SERVICE INSTRUCTIONS
ACROPRINT MODEL 200 CLIP-O-MATIC RECORDER
I. MOTOR AND DRIVEASSEMBLY
This combination Payroll and Job Cost Recorder is driven by a
115 volt AC, 60 cycle, 1 RPM motor. This motor revolves the
Minute Drive Cam exactly once each minute. The accuracy of
the recorder is built into this motor, which should keep perfect
time provided all the Drive-Train parts are properly installed,
adjusted, and lubricated.
To ensure long life and accuracy, the Acroprint Model 200
should be properly cleaned, oiled and lubricated at least once
every two years. However, if the Model 200 is installed in a
dusty or otherwise unusual location, more frequent cleaning
and lubrication may be required.
The 1 RPM Motor operates the Minute Drive Cam which
operates the Minute Drive Lever. Attached to the Minute Drive
Lever is the Minute Feed Pawl. The Minute Detent Pawl has to
be adjusted, so there will be a .002" clearance between the
Minute Detent Pawl and the Ratchet Tooth when the Minute
Drive Lever is in the rest position. Check for this clearance on
all teeth in the 60-Tooth Minute Drive Ratchet. This adjust-
ment is very critical to the operation of the clock. If there is no
clearance between the Minute Detent Pawl and Ratchet Tooth,
the Minute Feed Pawl will bind on the Minute Pawl Stop as
the Minute Feed Pawl tries to advance to the next tooth. This
will cause loss of time and will shorten the life of the 1 RPM
Motor. Too much clearance between the Minute Detent Pawl
and Ratchet Tooth will cause the minutes to print out of
alignment.
The area of contact,where the pin located on the Minute Drive
Cam meets the Minute Drive Lever, should be greased. The
points where the Minute Drive Lever bears on the Minute
Shaft, the pivotal points of the Minute Feed and Detent Pawl,
and the brass Minute Shaft Bearing near the Minute Drive
Gear should be oiled with a high grade #6 machine oil. The
areas mentioned above should be greased or oiled at least once
every two years.
II. TYPEHEADASSEMBLY
The Minute Typewheel features a Drive Gear molded onto it to
correspond with the Minute Drive Gear on the output of the
Motor Drive Gear. Before the Minute Drive Gear can be on
Minute Shaft, you must refer to the Hour Drop-off Cam which
is also molded onto the Minute Typewheel and is reinforced
with a hardened Steel Cam. This Cam is used to back the Hour
Follower Lever and let it “drop” once each hour or each
complete revolution of the Minute Typewheel. As viewed from
the bottom center of the Typehead Assembly, the “drop-off”
occurs when the Typewheel advances from “59” to “00”
minutes.
The tab on the Hour Follower Lever should clear the back side
of the Hour Drop-off Cam by .005" when the Minute
Typewheel is at “00” minutes and the Hour Follower Lever is
in a “thrown” position. This adjustment is made with the
setting of the Minute Drive Gear. Be sure Set Screws are tight
after this setting.
The Hour Typewheel Arbor extends through the Typehead
Rear Plate to which the 24-Tooth Ratchet is set. With the Hour
Ratchet Pawl assembled on the Stud (on the lower side of the
Typehead Rear Plate) and engaged in the Ratchet Teeth, set
Ratchet Pawl Stop Screw for Ratchet Pawl which is also
engaged in Ratchet Teeth to just touch the leading edge of the
Ratchet Pawl; then, back the Pawl Stop Screw to allow a .002
inch over-travel.
The same procedure as used above for the Hour Typewheel is
used to adjust the Day or the Date Typewheel. This Typewheel
is drive by a 1/4" shaft extending through the Typewheel Rear
Plate. A recorder which uses a Day Typewheel employs a 28-
Tooth Ratchet, and a Date Typewheel requires a 31-Tooth
Ratchet. On the rear side of the 24-tooth Ratchet we employ a
Day-Date Cam which advances the Day or Date Typewheel
Ratchet.
II. TYPEWHEELALIGNMENT
In order to set the 24-Tooth Ratchet to the Hour Typewheel
Arbor, manually advance the Ratchet by actuating the Hour
Follower Lever until the Day or Date Ratchet advances; then,
carefully rotate the Hour Typewheel to “12” midnight or “0”
hour to the bottom center printing position and in line with the
“00” minutes, which should have already been set. Tighten Set
Screws and check for binds or any misalignment. The Day or
Date Typewheel can now be set to the 1/4" shaft. Align the
Day or Date with the Hour and Minutes and tighten the
Ratchet Set Screws, making sure the Day-Date Ratchet and the
Hour Ratchet are not touching, which may cause binding.
Grease the Hour Drop-off Cam on the Minute Typewheel and
the Day-Date Cam. Also, apply grease lightly to the 24, 28, or
31-Tooth Ratchets. This should be done at least once every
two years.
When necessary to disassemble the Typewheels from the
Recorder, always clean and lightly oil the bearing surfaces
upon re-assembly.
1

It will be necessary to periodically clean the Typewheel
printing surfaces. DO NOT USEA SOLVENT cleaner, as
most solvents will eventually tend to “gum-up” the Typewheel
Assembly. Use a short bristle brush only.
IV. TYPEHEADASSEMBLY
A. REMOVINGTYPEHEADASSEMBLY
1. Remove Dial Assembly by loosening the one Screw
located on the underside of the Dial Assembly. Pull
the bottom of the Dial Assembly out to clear the
holding screw, then move the Dial Assembly up to
clear the Mounting Lugs on the Center Plates.
2. Remove four Screws (2 on each side) holding the
Card Receiver Support Plate. Remove Support Plate
by lifting straight up.
3. Remove both Screws from the Ribbon Guide. Do not
remove the Ribbon from the Ribbon Guide. Remove
the Chip Deflector. Loosen both Set Screws in Drive
Gear. Remove the four Typehead Mounting Screws
and two Hex Nuts from the Right Inside Plate.
Remove the four Typehead Mounting Screws from
the Left Inside Plate. Disengage Slide Shaft Latch
from Upper Slide Shaft so the Shaft can be removed.
Entire Typehead and Dial DriveAssembly will fall
forward, making Typehead removal easier. Move
Right Inside Plate to the right about an inch. The
Typehead can now be removed from the top.
B. DISMANTLINGTYPEHEADASSEMBLY
Loosen two Set Screws in Day-Date Ratchet. Remove E-Clip
from Detent Pawl and remove Ratchet. Disconnect Detent
Spring from Detent Pawl. Lift Day-Date Follower Lever off
Stud and disconnect (2) springs from Typehead Rear Plate.
Loosen Set Screws (2) in Hour Ratchet and remove Hour
Ratchet. Loosen Set Screw in Stud Collar and remove Collar.
Unhook Detent Spring from Hour Detent Pawl and remove
Detent Pawl (notice that Hour Feed Pawl and Hour Detent
Pawl are shorter than the Day-Date Pawl). Unhook Springs
from Hour Follower Lever and remove Lever. Loosen and
remove the four Typehead Spacers. Pick straight up to remove
Typehead Rear Plate. Now the Typewheels can be removed.
Before the Typewheels are separated, file the Set Screw marks
on Hour Shaft (Brass) and Day-Date Shaft (Steel). File lightly
to remove burrs. Now the Typewheels can be separated. The
Typewheels are in three different pieces (Day-Date, Hour, and
Minutes). The Day-Date Wheel has a solid 1/4" steel Shaft.
The Hour Wheel has a brass Shaft with 1/4" hole in the center.
The MinuteWheel, tenths or hundredths, has a molded Gear
and Cam on one side. Month,Year, and Symbol Wheels are
held to Typehead Front Plate by four Screws.
C. REASSEMBLINGTYPEHEAD
Put one drop of oil on Day-Date Wheel Shaft where it fits
Front Plate. Install Wheel in Typehead Front Plate. Oil the 1/4"
steel shaft and slip HourWheel over Shaft — Hour Wheel
should now spin freely on Shaft. If it does not, look for burrs
on Day-Date Shaft. Put Minute Shaft over brass Hour Arbor;
grease Hour Cam on Minute Wheel. Install Typehead Rear
Plate and secure with three of the four Typehead Spacers. Do
not install Spacer where the springs are going to hook in the
Typehead Rear Plate. Install this Spacer after all Springs are
connected to the Rear plate. All three Typewheels should spin
freely; if not free, check for burrs or misalignment. There is 1/
4" hole in all Typewheels in which a 1/4" Shaft can be inserted
for temporary Typewheel alignment. Insert this Shaft with
Minute Wheel at “00” printing position, Hour Wheel at 12:00
MIDNIGHT printing position, Day-Date Wheel at Monday
printing position, or DateWheel at 1st printing position. For
clocks with Month,Year and Symbol Wheels, the Month
Bracket has to be removed to reveal the aligning holes. Leave
this aligning shaft in Typewheels — it can be removed later.
Install Hour Follower Lever on Detent Stud. Connect springs
and put thin Spacer Washer on Stud. Install Stud Collar and
tighten Set Screw. With Set Screw tight, Hour Follower Lever
and Detent Pawl should have very little side play, but should
be free enough that the Detent Pawl will not bind with Spring
unhooked. Hold side play to a minimum. Connect Detent
Spring. Holding Hour Follower Lever and Detent Pawl out of
the way, install 24-Tooth Ratchet. Rotate Minute Wheel
counter clockwise until it stops. The MinuteWheel will stop
when Hour Follower Lever bottoms in Hour Cam. This will
also position Minute Wheel to be in a “00” printing position.
Manually operate Hour Follower Level so Hour Feed Pawls
drops into next tooth of Ratchet. Release Hour Follower Lever
and Ratchet will advance one tooth. Hour Detent Pawl should
drop into tooth and give about .002" clearance. If Detent Pawl
does not drop in or there is no clearance, check Minute Wheel
for “00” position. If Minute Wheel is in correct position and
there still is no clearance, adjust Ratchet Pawl Stop Screw.
Loosen Hex Nuts and unscrew Ratchet Pawl Stop Screw from
1/2 turn. Tighten Hex Nut. Too little clearance will cause
binding of Hour Follower Lever, resulting in Typehead losing
hours. Too much clearance will cause hours to be out of
alignment.
Attached to the 24-Tooth Hour Ratchet is a white, molded
Cam. This is the Day-Date Cam. The 24-Tooth Ratchet has to
be in position so Day-Date Follower Lever will operate at
12:00 MIDNIGHT. Install Day-Date Follower Lever on Detent
Stud, but do not connect Spring. Manually advance Hour
Ratchet until Day-Date Follower Level drops off Day-Date
Cam. Slip a .010" feeler gauge between Hour Ratchet and
Bushing in Typehead Rear Plate. Press firmly on Hour Ratchet
and tighten one (1) Set Screw in Hour Ratchet. Remove feeler
gauge. Do not tighten both Set Screws — this is a temporary
adjustment. Install Day-Date Follower Lever connecting
2

Springs to Typehead Rear Plate and install fourth Spacer.
Install Spacer Washer on Detent Stud and Day-Date Detent
Pawl; secure with E-clip. Detent Pawl should be free on
Detent Stud. If tight or binding, you might have to remove thin
Washer or grind side surface of Detent Pawl. Connect Detent
Spring. Detent Pawl and Day-Date Follower Lever should
have as little side clearance as possible yet be free of binds.
Install Day-Date Ratchet. There should be 1/16" clearance
between tab on Day-Date Follower Lever and Hour Ratchet.
To increase this clearance, file or grind edge of tab. Too little
clearance will bind Hour Ratchet and result in losing hours.
Adjust for .002" clearance between Detent Pawl and Ratchet
as was done on Hour Detent Pawl and Ratchet. Insert .010"
feeler gauge between Day-Date Ratchet and Hour Ratchet,
press firmly on Day-Date Ratchet and tighten one Set Screw.
Remove gauge and remove aligning Shaft from Typewheels.
Manually operate Hour Follower Lever. It should operate from
its own Spring tension all the way around the Hour Ratchet. If
there is binding, check for proper Spring tension, clearance
between Ratchets, roughness on Detent Pawl or Ratchets,
binding Detent Pawl or Typewheels, and clearance between
Day-Date Detent Pawl and Day-Date Ratchet. If the Typehead
has Month Wheel, install Month Wheel and Month Bracket.
Leave the four Month Bracket Screws loose and align wheel
with rest of Typewheels using a straight edge. Press firmly on
straight edge against Typewheels and tighten all four Screws in
Month Bracket.
Now Typehead can be installed in the recorder. Slide the
Typehead into Left Inside Plate being sure that Set Screws in
the Drive Gear are in a position so they can be reached and
tightened with an AllenWrench. Slide the Right Inside Plate to
the left. Before securing Typehead with the four Mounting
Screws, align Right Inside Plate with Dial Drive Shaft, Dial
Lock Shaft, and the two Stabilizer Bars. Tighten the Hex Nut
in the Stabilizer Bar and tighten Mounting Screws on the
Right and Left Inside Plate.
Before putting the Upper Slide Shaft back into side frames,
there is one crucial alignment. Slip Ribbon Guide on the Right
Inside Plate — do not install Screws. Install Upper Slide Shaft
and engage Slide Shaft Latch. Position Ribbon Guide and start
both Mounting Screws. The correct position for Ribbon Guide
is when the Ribbon is positioned as close as possible to
Typewheels but not touching. If the Ribbon touches the
Typewheels it is possible for the Minute Wheel to twist the
Ribbon. If the Ribbon is too far back, the time card can hit the
edge of the Ribbon and twist it. Ribbon positioning is very
important! Tighten Screws in the Ribbon Guide. Install the
Chip Deflector and tighten screws.
Position Drive Gear to Minute Wheel being sure the side of
the Gear does not rub the side of the Wheel, rotate the top of
the Drive Gear to the rear until Gear stops, and then tighten
both Set Screws in the Drive Gear. Install Card Receiver
Support Plate and start the four Mounting Screws.Align
Upper Card Receiver to Inside Card Receiver and tighten the
four Mounting Screws. Plug in the Recorder and print on a
card. The “00”on Minute Wheel will always be the aligning
reference for other Typewheels as explained earlier. Align all
Typewheels and tighten Set Screws in the Hour and Day-Date
Ratchets. Install the Dial Assembly by aligning the slots on the
back of Dial Assembly with the lugs on the Inside Plates.
Secure the Dial Assembly by tightening the Screw on under-
side of Dial Assembly. Adjust printing as Follows:
1. Heavy or light printing is corrected by movingYear-
Month Bracket in or out. A simple way to do this is to
loosen the four Screws in the Bracket and push the
Bracket all the way in. Snug down the four screws. Take a
print — it should be light printing. Place a punch or
screwdriver on the top outside corner of Bracket and tap
Bracket down until printing is uniform. Tighten the four
Bracket Screws. Heavy print on Month or Symbol will
cause light printing on other Typewheels, which would be
hard to read.
2. The Month Latch has an elongated mounting hole.
Loosen Latch Mounting Screw and slide Latch up or
down to correct alignment. Sometimes moving Latch will
not align month printing. In that case, theYear-Month
Bracket must be moved. This can be done with a punch
and Hammer. Tap Bracket up or down. After moving
Bracket, check the four Screws for tightness.
Steps 1 & 2 might have to be made in reverse order — adjust
alignment before heavy or light print adjustment is made.
V. CARD RECEIVER
As the time card is inserted into Upper Card Receiver, the left
corner of card will contact the Left Card Guide. The Left Card
Guide is spring loaded which will push the time card to the
right. The purpose of the Left Card Guide is to insure that the
time card will align with the Punch and Die and to insure that
the right edge of time card will actuate the Right Hand Guide
Operating Lever. If the time card does not actuate the Right
Hand Guide Operating Lever, the Recorder will not print. This
is why the Card Receiver should not be more than one thirty-
second
(1/32") of an inch wider than the time card you plan to use.
When the time card actuates the Right Hand Guide Operating
Lever, this closes the Cancellation Microswitch. As the card
goes further down the Card Receiver, the left corner of card
will hit the Card Trip Lever which will close the Print
Microswitch. When the Print Microswitch closes, the follow-
ing functions will take place: Solenoid will energize and rotate
the Hammer Shaft Assembly, Card Punch will remove left
corner of time card, Platen strikes card for print, Cancellation
Bracket strikes Cancellation Pawl opening Cancellation
Microswitch, and Hammer restores to normal. This sequence
takes place each time the Recorder prints.
3

The Cancellation Microswitch and the Print Microswitch are
wired in series. Both Microswitches must close before a print
can be made. Once a print has been made and the time card is
still in the Card Receiver, the blade on the Cancellation
Microswitch will be under the step in Cancellation Pawl. The
time card must be pulled up far enough so that the bottom
edge of the time card will allow the Right Hand Operating
Lever to restore to a normal position with the Cancellation
Microswitch. Now the recorder is ready to make another print.
The Cancellation Microswitch should close each time a time
card is inserted; also, when there is not a time card in the
Receiver, the Cancellation Pawl should be free to latch with
the blade on the Cancellation Microswitch. Both of these
adjustments are made by forming the blade on the Cancella-
tion Microswitch.
The Card Trip Lever has an extension on the back side which
fits into the Punch and Die. This extension is what the time
card presses when closing the Print Microswitch. As the Print
Microswitch closes, the blade will stop on the Print
Microswitch Limit Screw which is located in the Left Side
Frame. The Limit Screw can be adjusted for various printing
spacing on the time card. The further the time card goes into
the Die before printing, the further apart the distance between
each print will be on the time card. Likewise, the shorter the
distance that the time card travels into the Die the least
distance between each print. To test for proper adjustment, set
recorder to PM hours, especially on the models that use 1-12,
1-12 hours, and make certain that the underscore does not
print over the previous registration. Turn the Limit Screw in
for less spacing and out for more spacing. It may be necessary
at times to form the blade on the Print Microswitch for the
spacing you need, if proper spacing cannot be obtained by
adjusting the Limit Screw.
As the time card is punched it will go deeper into the Card
Receiver. To eliminate any excess side clearance that might
develop as time card goes deeper into the Card Receiver, there
is a Lower Card Margin mounted under the Punch and Die.
The Lower Card Margin is adjusted to keep the time card
straight as the time card goes through the Punch and Die. To
test for this adjustment, print half of the time card, unplug
recorder and insert the time card. With time card touching the
Right Card Guide, the left side of time card should clear the
Lower Card Margin, about one-sixteenth (1/16") of an inch.
Loosen the Mounting Screws in Lower Card Margin and move
Lower Card Margin left or right for the correct clearance, and
then tighten Mounting Screws. Insufficient clearance between
the time card and the lower Card Margin will cause the time
card to fit too tightly and roll the left side of time card. Too
much clearance will cause the printing to be out of alignment
and affect the spacing between prints.
VI. RIBBON DRIVE & REVERSE
Every time the Model 200 prints, the Hammer Shaft pulls the
Ribbon Feed Lever down. The Ribbon Feed Lever should be
adjusted by the two Set Screws so the Ribbon Feed Pawl will
advance the Ribbon Ratchet 2 teeth.Attached to the Ribbon
Feed Lever is the Ribbon Feed Pawl. The Ribbon Feed Pawl
will engage with the Ribbon Feed Ratchet and rotate the
Ribbon Feed Ratchet 2 teeth every print. The Ribbon Reverse
Shaft is driven by the Ribbon Feed Ratchet. There are two
Gears on the Ribbon Reverse Shaft that drives the Ribbon
Spool Shaft.Adjust the Ribbon Reverse Shaft by aligning it
flush with the hub on the Ribbon Feed Ratchet and tighten the
two Set Screws in the Ribbon Feed Ratchet. Push the Ribbon
Feed against the Left Side Frame, the Left Side Frame is the
stop for the Ribbon Reverse while driving the Right Ribbon
Spool Shaft. Then adjust the right Ribbon Drive Gear to mesh
with gear on the right Ribbon Spool Shaft. Do not mesh these
gears too tightly as this will cause a bind. The Ribbon Drive
Gear on the right Ribbon Spool Shaft can be adjusted up or
down for proper gear mesh. Now that the Ribbon Drive Gear
is in proper mesh, tighten the Set Screw in the right Ribbon
Drive Gear. While the Ribbon Reverse Shaft is in this position
(driving the right Ribbon Spool Shaft) space the Ribbon
Reverse Shaft Collar 1/8" from the Left Side Frame and
tighten the Set Screw in the Collar. This Collar will be the stop
on the Ribbon Reverse Shaft while driving the left Ribbon
Spool Shaft. Push the Collar against the Left Side Frame, slide
the left Ribbon Drive Gear into proper mesh with left Ribbon
Spool Gear and tighten the Set Screws. Adjust the Gear on the
left Ribbon Spool up or down for proper gear mesh.
When the Ribbon Reverse Levers are to the left, the Ribbon is
winding on the Right Spool. The Ribbon Reverse Levers are
held in this position by a Stud in the Ribbon Reverse Bracket
and toggle Pawl on the Ribbon Reverse Lever Assembly.
Adjust Ribbon Reverse Flange left or right so that Stud in the
Ribbon Reverse Bracket is equal distance on each side of the
Toggle Pawl. This adjustment can be checked by manually
moving the Ribbon Reverse Levers left and right noticing the
Stud position to the Toggle Pawl.
On each Ribbon Spool Shaft is a Ribbon Shaft Tension Spring
and Collar. The purpose of this Spring is to put tension on the
Ribbon Shaft so that the Drive Gear will mesh, and the Ribbon
Spool will not unwind too freely, but will turn easily. Too
much tension will impede Ribbon Drive and printing. Too
little tension may cause the Ribbon to twist if the Ribbon
unwinds too freely.
Near each end of the Ribbon is a Reversing Rivet.As the
Ribbon moves through the Ribbon Reverse Levers, the
Reversing Rivet pushes the Ribbon Lever and moves the
Levers in the direction the Ribbon is traveling. At the same
time, the Stud in the Ribbon Reverse Bracket moves to the
other side of the Toggle Pawl which moves the Ribbon
4

Reversing Flange and the Reversing Shaft. This is how the
Ribbon reverses.
VII.PLATEN INSTALLATIONANDTRIMMING
Sometimes it is necessary to install a new Platen when
changing from three wheels to four wheels or when installing
aYear or Symbol Wheel. Remove old Platen from Hammer.
Before installing new Platen, apply adhesive substance to
Hammer. Beveled edge of Platen should be inserted into the
Hammer towards the top. Insert new Platen in Hammer
making sure Platen is in position to hit all Typewheels. Having
the Platen in the correct position, we can now press or hammer
Platen to be sure Platen is seated in Hammer. Manually push
in on Hammer and release; this will transfer typewheel print to
Platen. With a razor blade, remove all Platen around the
minute character. Take a sample print on time card. If print
quality is not adequate, the Platen may need to be filed or
ground flat.
VIII. ELECTRICAL INFORMATION
One wire of the AC line (Terminal 4) connects to oneAC
terminal on the full wave bridge Rectifier. The other AC wire
(Terminal 2) will connect to the Normally Open (NO) Termi-
nal of the Print (Left Card) Microswitch, leave the Print (Left
Card) Microswitch thru the Common (COM) Terminal and
proceeds to the Normal Open (NO) Terminal of the Cancella-
tion (Right Card) Microswitch thru the Common (COM)
Terminal and connect to the other AC terminal of the Rectifier.
The Print Solenoid is connected to the + and - terminals on the
Rectifier (one wire on the Solenoid to +; the other wire to -).
Always be sure Left and Right Card Microswitches are
connected toAC. NOTE: The Microswitches are connected in
series — (both Microswitches have to close to complete the
circuit for recorder to print).
IX. SERVICETIPS
A. Losing time (minutes).
1. Check 1 RPM motor with second hand on watch —
Minute Drive Lever should operate at the same
second for 4 or 5 minutes.
2. Binding MinuteWheel against Drive Gear.
3. Binding Hour Reduction Gears.
4. Minute Cam loose on motor — Set Screw loose in
Drive Gear.
5. Minute Detent out of adjustment.
6. Check parts for lubrication.
7. Ask if they experienced a power failure recently.
B. Gaining time (minutes).
1. Minute Feed Pawl backing up two (2) teeth.
2. Minute Feed Pawl and Detent Pawl out of adjust-
ment. When this adjustment is incorrect, the Hour
Cam on Minute Wheel wears the point off Hour Cam.
On the 59th minute, the Minute Feed Pawl comes out
of the 60-tooth Ratchet.At this time the Minute
Wheel can be rotated by the Hour Follower Level.
This will account for one (1) minute fast. Then the
recorder will take on (1) normal minute.
C. Losing time (hours).
1. Hour Ratchet binding on Typehead Rear Plate.
2. Too much side play in Hour Follower Lever allowing
Hour Feed Pawl to get off Hour Ratchet.
3. Day-Date Lever binding Hour Ratchet.
4. Hour Detent binding — not enough clearance.
D. Gaining time (hours - Typewheels one or more hours
ahead of clock face).
1. When Hour Typewheel is at 12:00 midnight, check
clearance between Day-Date Cam and Cam Follower
of Day-Date Lever. There should be 1/16" clearance
between Cam and Follower at midnight. Check Hour
Ratchet for adjustment and alignment. It may be
necessary to remove Day-Day Cam and grind about
1/16" for correct clearance.
2. Binding Hour Detent Pawl.
3. Hour Pawl Stop Screw loose — causing hours to
advance two hours at a time.
4. Set screws in Hour Ratchet loose, causing Hour
Wheel to spin freely and appear to gain time.
E. Day or Date not changing.
1. Too much side play in Day-Date Follower Lever.
2. Day-Date Detent binding — not enough clearance.
3. Set Screws in Day-Date Ratchet loose, causing Day-
DateWheel to spin freely.
4. Day-Date Pawl Stop Screw too tight, not allowing
Pawl to advance.
5. Clock may be set 12 Hours off, so Day-Date would
appear to advance at noon instead of midnight.
F. Light or weak print.
1. Ribbon worn out or not reversing.
2. Ribbon Guide loose.
3. Hammer Shaft and associated parts dry — need oil
G. Not Printing.
1. Card Receiver out of adjustment — too wide for card.
2. Rectifier or Solenoid burned out.
3. Microswitch burned out.
4. Bad connection at Terminal Block or Microswitch.
H. Ribbon not reversing.
1. Ribbon Drive Ratchet loose on Ribbon Shaft.
2. Ribbon Drive Arm loose on Hammer Shaft.
3. Ribbon Feed and Detent Spring broken.
4. Gears loose on Ribbon Drive Shaft on Ribbon Spool
Shaft.
5. Ribbon Reverse Flange loose or out of adjustment.
I. Platen Replacement. SEE PREVIOUS TEXT.

X. RECTIFIERTEST
A. Preliminary Information
1. Terminal Configuration and Schematic Diagram.
2. Types of Failures — Two types of Rectifier failures could
cause the inoperation of the Rectifier Power Drive System
— these are:
A. The opening of the Bridge Diode element/leg.
B. The shortening of a Bridge Diode element/leg.
3. Circuit Failure Symptoms:
A. Open Bridge Diode Element/Leg: Should this occur,
there would be a reduction of DC output voltage to
the load circuit thus causing no or intermittent
operation.
B. Shorted Bridge Diode Element/Leg: Should this
occur, there would be no DC output Voltage with AC
input Circuit Breakers opening.
B. In Circuit Testing
1. Procedure
A. Before turning system on, disconnect the Load
Circuit from the Positive and Negative Terminals
of the Rectifier.
B. Place DC Voltmeter between the Positive and
Negative Terminals (1000 ohms/volt typical or
higher) with the scale switch set on applicable
range which would allow the reading of 250
volts DC or less.
C. Activate System: Meter should read as follows:
For AC For DC
Input Output voltage
Voltage Min. Max.
110-125vac 85vdc 12vdc
208-250vac 170vdc 240vdc
D. If meter indicates within the acceptable maxi-
mum/minimum range, the Rectifier is operating
properly with the problem most likely being in
the Load Circuit.
2. Precautions
A. Make sure that there in no accidental shorting of
the Terminals of the Rectifier by screw drivers,
other tools or metallic objects when the AC Input
has been activated. This could cause a severe
overload, thus causing the Rectifier to fall.
B. Make sure that no body contact is made with any
Terminals of the Rectifier since voltage and
current levels could prove to be lethal.
C. Out of Circuit Testing: This method permits a
rough check of the Rectifier at convenient/safe
voltage levels. It does not assume that 100% of
the Rectifiers tested by this method will function
properly under rated voltage and current condi-
tions, but rather is analogous to the simply OHM
meter check for half wave Rectifier Diodes.
1. Procedure
a. BasicTest Circuit
b. With or without the primary voltage of T1
applied, place the Rectifier to be tested into
the circuit as shown below.
c. Place DC voltmeter between the Positive
and Negative Terminals (1000 ohms/volt
typical or higher) with the scale switch set
on applicable range which would allow the
reading of 15 volt DC or less.

Minimum Maximum
8.5vdc 14.5 vdc
e. If meter indicated with the acceptable
maximum/minimum range, the rectifier is
operating properly.
