Main Switch
Power On: Push main switch once quickly
while printer is off.
Form Feed: Push once quickly while printer is
on and partial page has been sent to printer.
Power Off: Push twice quickly.
Charge battery: Push once and hold for
several seconds until green BATTERY
indicator stays lit. When printer finishes
discharging battery, it starts to charge
battery, and green BATTERY indicator starts
to blink.
Refresh battery: While in Charge mode, push
once and hold for several seconds until
green BATTERY indicator starts to blink.
Power off during Charge or Refresh mode:
Push twice quickly.
Density Dial
Density dial is on side of printer closest to
operation panel. Larger numbers make
prints darker. Smaller numbers make prints
lighter.
Charging the Battery
1Make sure printer is off and it is
connected to AC power outlet with AC
adapter and power cord.
2Press main switch and hold it down for a
few seconds until green BATTERY indicator
stays lit. This puts printer in Charge mode,
which completely discharges battery and
then charges it. Green BATTERY indicator
stays lit until discharging is completed;
then it blinks until charging is completed.
When finished, printer turns itself off.
Tips on Using the Battery
◆Charging battery after it has been
completely discharged takes about 70
minutes.
◆When you run printer on battery power,
it can print approximately 30-35 pages
on a full charge.
◆Darker prints discharge battery faster
than lighter prints do. Use density dial to
adjust lightness and darkness.
◆Printer’s protective vinyl case has sleeve on
inside for extra battery. With two batteries,
you can print twice as many pages before
you have to charge batteries.
Serial Handshaking: Used with serial interface.
DTR handshaking: set switch 7 to ON. This
disables Xon / Xoff handshaking. Xon / Xoff
handshaking: set switch 7 to OFF. Letter/A4
and Letter/Legal models: set switch 6 to OFF.
Auto-off Timer: Printer must be powered from
its battery. When switch 8 is OFF, printer turns
itself off after 60 seconds if it is not receiving
data (unless there is data in printer buffer).
NOTE: Your Ni-Cd battery will last much longer
and carry a greater charge if it is always
completely discharged prior to charging.
Refreshing the Battery
You may refresh a seasoned battery
occasionally when you don’t have time to
completely discharge and charge it.
Refreshing a battery “tops off” the charge
without first discharging battery.
CAUTION: This procedure is not recommended,
particularly with a new battery, as it may reduce
the battery’s life and its ability to carry a charge.
1Make sure printer is off and it is
connected to AC power outlet with AC
adapter and power cord.
2Press main switch and hold it down for a
few seconds until green BATTERY indicator
stays lit. This puts printer in Charge mode.
3Press main switch and hold it down for a
few seconds until green BATTERY indicator
starts to blink. This bypasses discharging
process and puts printer in Refresh mode,
which charges battery. Green BATTERY
indicator blinks until charging is completed.
When finished, printer turns itself off.

Clearing a Paper Jam
Remove paper as follows when a jam
occurs.
1Open release cover as far back as it will
go. See figure.
2Gently pull paper out of the printer.
3Reset printer by turning it off and back
on again.
When you reset printer, you lose data for
page that was printing when jam
occurred. Printer will print remaining
pages. If necessary, reprint page that
jammed as separate print job.
POWER indicator does not light.
If you are using AC adapter, make sure it is
connected properly. Also make sure AC
power outlet is “live.”
If you are using battery, make sure it is
installed properly. If it is installed properly,
follow procedure for charging battery.
POWER and
BATTERY
indicators are blinking.
A battery error has occurred. Make sure
battery has been installed and connected
properly. If battery is connected properly,
Application
should be sending
data to printer, but
green DATA indicator is not lit.
Make sure interface cable matches port
(parallel or serial) to which computer is
sending data. If you are using serial cable,
make sure serial port speed on printer and
computer match. DIP switches 1 and 2
control speed of serial port.
Green DATA
indicator goes
out while page is
in printer.
Application did not send full page of data.
Remove paper from printer by pressing main
switch once quickly to “form feed”
incomplete page.
What To Do if Nothing
Prints
Make sure you are using recommended
paper and loading it with print side (smooth,
coated side) away from you.
Application may have sent a form feed
command on a blank sheet. Try printing
another print job such as a one-page
memo.
Printer may be in cleaning mode. Make sure
DIP switch 4 is OFF.
POWER and
DATA indicators
are blinking.
A data I/O error has occurred. If you are
using parallel interface cable, parallel
connection may be defective. Replace
defective part—most likely interface cable.
If you are using optional RS-232C serial
interface cable, make sure serial port speed
and handshaking on printer and computer
match. DIP switches 1 and 2 control speed
of serial port. Switch 7 controls handshaking.
POWER
indicator is
blinking and
BATTERY indicator is on.
Printer is attempting to charge battery, but it
is not receiving any AC power. Make sure
you have connected printer to AC power
outlet.

you may have tried to charge battery while
it is overheated. Allow battery to cool before
continuing.
If indicators still show a battery error, battery
may be defective or printer may need
service. Call Pentax and ask for Technical
Support.

Inserting Paper
1Use both hands to hold paper straight
while you insert it into printer’s paper input
slot. Make sure bottom edge of paper is
parallel to feed roller.
Make sure smooth, coated side of paper
faces the back of printer.
2Press paper gently and evenly into
printer’s input slot until roller pulls it into
starting position, then let go.
If paper is skewed after printer pulls it into
starting position, do as follows.
◆If printer does not start to print
immediately, open release cover as
far back as it will go. Pull paper out
and reinsert it. Close cover.
◆If printer does start to print, wait for
page to be printed and then reprint
page if necessary.
TIP: If you insert paper before you start print job,
you will have time to adjust paper if it is skewed
after printer pulls it into starting position.
If serial port speed and handshaking are
correct, serial connection may be defective.
Replace defective part—most likely serial
interface cable.
POWER
indicator is
blinking and
BATTERY indicator is off.
Thermal print head has overheated. Turn
printer off or wait until POWER indicator light
stops blinking before you continue printing.
