CAUTION
To comply with FCC part 15, subpart J, electromagnetic inter-
ference requirements for computing devices, a shielded signal
cable is required
for either serial or parallel operation of the
Model 880 printer. TI cable part number 2223106-0001 for paral-
lel
operation or part number 2230504-0001 for serial operation or
equivalent should be used. Failure to use the properly shielded
cables
may result in radio frequency interference in excess of
the levels allowed by law. The user of equipment found to be
out of compliance would be liable for any interference and
corrective action to eliminate that interference.

2.2 INSTALLING THE PRINTER
With all components unpacked and accounted
for, follow these steps to prepare the printer for
operation.
1. Set the printer on a level surface that is
able to safely support 25 kg (55 Ib). If the
printer is puton a metal surface, the metal
must be grounded to prevent electrical
interference. Be sure that the weight of
the printer is not pressing on the back
paper chute.
CAUTION
Do not obstruct the air intake and
exhaust vents on the sides of the
printer; damage to the printer from
heat can occur. Figure 2-2 shows
the printer dimensions.
2. If you ordered the optional Texas
Instruments printer stand (TI part number
999841-0001), fasten the printer to the
stand according to the assembly instruc-
tions provided
with the stand.
3.
If you ordered the optional Texas
Instruments stand-mounted paper basket
kit (TI part number 999839-0001), mount
the paper basket on the printer stand
according to the assembly instructions
provided with the paper basket kit.

4. Open the printhead door (Figure 2-3) and
remove the cardboard shipping material
from the printhead.
5. Manually slide the printhead from side to
side. Be sure that the printhead and con-
nected wire rope move freely.
6. Close the printhead door.
2.3 INSTALLING THE PAPER BASKET
f
~
1. Install the accessory paper basket kit (TI
part number 994442-0001) as shown in
Figure 2-4.
2. Fasten the basket to the printer by com-
pressing the basket and inserting the
pivot pins into the holes on the back of
the printer.
1
NOTE
If you are not installing the paper bas-
ket accessory, you must provide
another suitable method for holding
the printer output. For correct printer
operation, any other paper holding
device must be connected to printer
ground to prevent electrostatic dis-
charge.

2.4 INSTALLING THE RIBBON
CAUTION
Use of ribbon not meeting TI speci-
fication 2246601 can cause exces-
sive
printhead wear and may void
warranty. (TI ribbon Part No.
2246601.)
Followthese steps to install a new ribbon.
1. Set the power switch to the OFF position.
2. Open the printhead door.
3. Make a note
of the position of the print-
head adjustment lever. Then move the
lever awayfrom the platen by pushing the
lever slightly
to the right and then pulling
it to the front of the printer as shown in
Figure 2-5.

"ADJUSTING THE PRINTHEAD" proce-
dure in subsection 2.8.
2.5
LOADING THE PAPER
The Model
880 Printer has a bottom and rear
paper path (see Figure 2-8). Either path can be
used for single-thickness forms. The bottom path
is recommended for multiple-thickness forms. To
PAPER OUT
SWITCH BOTTOM PATH
load paper, refer to Figures 2-8 and 2-9 and com-
plete the following steps.
1. Open the printhead door.
2. The left tractor must be to the left of the
paper-out switch (Figure 2-8).
If it is not,
loosen the locking lever (Figure 2-9) and
slide the left tractor to the left so that
when the paper
is installed, the paper will
cover the paper-out switch. Tighten the
lock lever.
3. Open the covers on both tractors.

4. Use the printhead-adjustment lever to
move the printhead away from the platen.
5. To load paper through tile back paper
path,
a. Put the paper supply in back of the
printer.
b. Insert the paper, with the side to be
printed facing down, into the paper
path at the back of the printer until the
paper appears at the platen. Align the
paper so that it does not rub against
the sides ofthe paper path.
c. Go to step 7.
6. To loadpaper through the bottom path,
a. Put the paper supply under the table or
stand.
b. Insert the paper, with the side to
be
printed facing forward, into the bottom
paper path until the paper appears at
the platen. Align the paper so that it
does not rub against the sides of the
table slot or the sides of the bottom
paper path.
c. Go to step 7.
7. Loosen the locking lever on the right
tractor and adjust the tractor to accept
the paper width.
8. Put the paper in both tractors with the
holes on the tractor pins. Make sure you
place corresponding holes on correspond-
ing pins.
9. Close the tractor covers and move the
right tractor to pull the paper tight across
the platen. Then tighten the locking lever.
10. Check the alignment of the paper supply
with the paper path. Paper must not
touch either side
of the path.
11. Return the printhead to its original pOSi-
tion (step 4) using the printhead adjust-
ment lever.
2-6
NOTE
To prevent possible damage to the
printhead and platen, do not operate
the printer without a ribbon and paper,
or beyond the width of the paper.
2.6 CONNECTING THE POWER CABLE
Make sure thatthe printer is adequately grounded
by plugging the power cable into a three-wire
power receptacle.
CAUTION
Refer to the identification label on
the back of your printer for correct
voltage levels. An incorrect voltage
can cause damage to the printer.

Figure 2-11. Three-Wire Power Receptacle
CAUTION
The printer must be connected to a
three-wire (with earth-ground) ac
receptacle. If an extension cable is
needed,
the cable must be a three-
wire cable which includes an earth-
ground connection. Failure to
provide an earth ground can cause
faulty operation, data errors, possi-
ble damage to the printer, and pos-
sible electrical hazard to the
operator.
2.7 ACTIVATING THE PRINTER
CAUTION
Before activating your printer,
allow at least 15 minutes after
unpacking for it to adapt to
ambient temperature and
humidity.
When the power switch is put in the ON position,
the printerdoes
an automatictest that takes about
30 seconds. While the test is being done, the fol-
lowing events should occur:
1. All indicator lights (except Command)
turn on.
2. Indicator lights turn off in the following
order:
a. On Line
b. Paper
Out
c. Test
d. Menu
e. Error
3. The carriage moves to the right bumper
and then tothe leftbumper.
4. The printermakes ashort audible tone.
5. The Power and Normal indicators
remain on. The
Paper-Out indicator
flashes if you have not loaded paper. The
On Line indicator turns on if the printer is
configured to power-up on line (configu-
ration code 9B selected).
If your printer does its automatic power-up test
without these results,
see Section 4, liST ATUS
REPORT AND PROBLEM ANALYSIS."
2.8 ADJUSTING THE PRINTHEAD
The printhead must be adjusted to the thickness
of the form used. For the initial adjustment, and to
make corrections for different paper thicknesses,
complete the following steps:
1. After loading paper, move the printhead
toward the platen by pushing the print-
head adjustment lever slightly to the right
and then toward the back
of the printer.
Allow the printhead barely to touch the
paper.
2-7

2222627-8
Figure 2-12. Printhead Adjustment Lever
2. Print a barberpole test (described in
subsection 2.9). Ink smears will appear on
the paper if the printhead
is too close to
the platen. Incomplete characters or no
characters will appear
if the printhead is
too far from the platen.
3. Continue adjusting the printhead and
printing barberpole tests until the print
appears sharp and dark.
NOTE
Adjusting the printhead cannot com-
pensate for a
worn-out ribbon. Replace
the ribbon if the printed characters are
too light.
2.9 PRINTING THE BARBERPOLE
Before printing the barberpole test, the printer
must be
off line. If the On Line indicator is on,
press the On
