THERMAL PAPER
We recommend using B-G Instruments’ type TP-3 thermal
paper in the DataPlot model PM1320 Print Mechanism. This
paper produces a permanent black-on-white image that is
stable with time and it does not tend to stick to the printhead
as do some other brands. Use of waxy-coated papers should
be avoided because of their tendency to adhere to the
printhead and cause a buildup of material on the head. TP-3 is
a 2.6 inch wide, high quality facsimile grade paper that can
produce high resolution permanent copy in the PM1320
printer. It is available from B-G Instruments in cartons of 36
rolls, or in larger quantities.
CAUTION --- NON-WARRANTY
PRINTHEAD DAMAGE
The DataPlot CB1320 control board applies power to the
selected thermal dots for a period of time sufficient to exceed
the thermal paper activation temperature, or about 2
milliseconds. If electrical power is applied to these elements
for a significantly longer period, or for too high a duty cycle, or
in some 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 is not covered by warranty. For this reason, it is important
that the print mechanism be operated only by the DataPlot
model CB1320 control board and that the applied power be as
specified in the CB1320 Technical Data and Instructions sheet.
WARRANTY
B-G Instruments will repair or replace, at its option, any
DataPlot model PM1320 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 CB1320 control board and
B-G Instruments’ type TP-3 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.
PRINT SPEED
When driven by a CB1320 Control Board, the PM1320 print
mechanism can print approximately 150 dot rows per second
(somewhat slower for rows containing more than 64 printing
dots). At .005” per step, the maximum paper speed is,
therefore, about 0.75” per second. Rows of 5x7 characters can
be printed at about 5 lines per second, somewhat slower for
bold or larger size characters.
