GENERAL DESCRIPTION
The DataPlot model PM
1416 Print Mechanism incorporates a thermal printhead with
416 heat element dots arrayed in a single line across the width
of the paper. The mechanism holds a supply roll of 4.5" wide
thermal paper and moves the paper past the printhead in steps
of approximately .005 inch. When driven by a DataPlot CB
1416 or CB 1100 Control Board, the print mechanism steps the
paper forward, pausing after each step to heat selected dots. In
this manner, a dot matrix representation of alphanumeric and/or
graphic data can be printed.
MOUNTING
The DataPlot model PM 1416 print mechanism is designed to
mount to the rear surface of a panel, using four 6-32 screws.
The mounting and cutout dimensions are shown on the
reverse side of this sheet. If you prefer to use mounting studs,
we can eliminate the mating PEM nuts and you can use nuts
to secure the print mechanism to the panel.
CONTROL BOARD CONNECTION
This print mechanism is designed to operate reliably when
driven by the B-G Instruments' DataPlot model CB 1416 or
CB 1100 control board or another board specifically approved
by B-G Instruments for that purpose. Attempting to operate it
in any other way may cause permanent damage that would not
be covered by warranty. With all system power off, attach the
supplied ribbon cable between the 26-pin printhead connector
and connector J3 on the control board, being sure to observe
correct polarity by aligning the red dots on the connectors with
those on the cable ends. Also connect the 8
RE
SOLUTION
The 416 thermal dot elements are uniformly spaced at 100 dots
per inch, with centers 0.010 inches apart. The mark made by
each element is slightly larger than this spacing, so that the
printer can print solid lines and solidly filled areas. The
standard mechanism advances the paper approximately 0.005
inches between steps, providing a dot matrix pitch of .010"
across the paper by .005" along its length. The CB 1416 and
CB 1100 Control Boards and software use this dot matrix to
produce printed characters and graphic images.
PAPER LOADING
A paper sensor in the PM 1416 provides signals that are used .
by the control board to stop printing when paper runs out and
to "autoload" a new paper roll. To load the printer, be sure the
power is on and insertthe paper end into the slot behind the
rubber platen with the sensitive side (outside on the roll) away
from the platen. When the paper is inserted, the platen will run,
pulling about 2 inches of paper through. On print mechanisms
with a head lift tab, you may also install paper by lifting the
printhead and inserting the paper manually.
MAXIMUM PRINT SPEED
When driven by a CB 1416 or CB 1100 Control Board, the
PM 1416 Print Mechanism can print approximately 125 dot
rows per second (somewhat slower for rows containing more
than 64 printing dots). At .005" per step, the maximum paper
speed is about .6 inches per second. Rows of 5x7 characters
can be printed at a rate of about 5 lines/second.
pin stepper motor connector cable to
connector J1 on the controlboard. This
connector is keyed to facilitate correct
polarity assembly. Refer to the control
board data sheet for instructions on
applying power and operating the printer.
The standard length of these cables is 18
inches. Contact us if you need shorter or
longer cables in your application.

THERMAL PAPER
We recommend using B-G Instruments' type TP-4 thermal
paper in the DataPlot model PM 1416 Print Mechanism. This
paper produces a stable black on white image. Unlike some
waxy coated papers, it does not stick to or-cause material to
build-up on the printhead. TP-4 is a 4.5 inch wide, high quality
facsimile grade paper that can produce high resolution
permanent copy in the PM 1416 printer. It is available from
B-G Instruments in cartons of 24 rolls, or larger quantities.
CAUTION --- PRINTHEAD DAMAGE
The DataPlot CB 1416 and CB 1100 Control Boards apply
power to the selected thermal dots for a period of time
sufficient to exceed the thermal paper activation temperature,
orabout 2 milliseconds. If electrical power is applied to these
elements for a significantly longer period, or for too high a
duty cycle, or in any other improperly controlled manner,
irreversible printhead damage may occur. Such damage can be
readily detected, as the affected dots will print only lightly, if
at all, and isnot covered by warranty. For this reason, it is
important that the print mechanism be operated only by the
DataPlot model CB 1416 or CB 1100 Control Board and that
the applied power be as specified in the control board's
Technical Data and Instructions Sheet.
Locations and dimensions for panel
mounting holes and paper exit
cutout are shown at the left. We
recommend inserting a transparent
tear-off bar in this cutout. Contact
B-G Instruments for further
information.
The paper supply roll
compartment is usually covered by
a removable door set flush in the
front panel and secured by captive
screws to the two leftmost nut
inserts shown.
Brackets are also available from
B-G Instruments for attaching the
printer control board to the rear of
the print mechanism.
ALTERNATE PAPER SUPPLY HOLDERS
The PM 1416 print mechanism is available in several versions,
varying only in the manner of holding the paper supply roll.
The version pictured in this data sheet is model PM
1416-PTVF, one of the more popular versions, that holds the
paper roll in a front-loading tray. We also offer these
mechanisms fitted with a rear-loading tray,. an axle paper roll
mount or a spring holder. Upon your request, drawings of the
other standard configurations will be sent to you by phone or
fax. Other paper supply holding fixtures have been designed
for other customers with special mounting requirements. Let
us know what works best in your application.
WARRANTY
B-G Instruments will repair or replace, at its option, any model
PM 1416 Print Mechanism that malfunctions because of faulty
manufacture within one year after its original date of sale,
provided that the mechanism has been used exclusively with a
properly functioning CB 1416 or CB 1100 Control Board (or
other control board specifically authorized by B-G Instruments)
and B-G Instruments' type TP-4 thermal Paper, and:
1. neither the print mechanism nor its control board have been
modified in any way not specifically authorized by B-G
Instruments, Inc., and
2. electrical power applied to the control board has
always been within specifications for that board, and
3. the mechanism shows no evidence of electrical, thermal
or mechanical damage, and
4. the mechanism has printed fewer than 100 million dot
rows and less than 100,000 feet of paper.
