SETUP
Opening and closing the printer
You must open the printer to change the battery or media. Two cover
clips hold the cover closed. To open the printer:
1. Place the printer on a flat surface, with the top cover facing up.
2. While holding the printer, pull the bottom of each cover clip away
from the printer body and upward.
3. Pull the top of each clip clear of the printer cover.
4. Swing the printer cover all the way open.
To close the printer:
1. Place the printer on a flat surface, with the open cover facing up.
2. Position the label stock over the paper door edge.
Note:
If you are using the optional peel-back accessory, thread
the label stock through the printer as shown in Figure 5 on
page 9.
3. Lower the printer cover and hold it closed.
4. Engage the top of each cover clip on the mating lips on the printer
cover, then press the bottom of each clip against the printer body.
The clips will snap into position.
Installing the battery
(Not applicable to externally-powered printers)
Code Courier uses an internal rechargeable battery, and is shipped
with the battery discharged and uninstalled. To install the battery:
1. Open the printer.
2. The battery tray is located to the
left of the paper holder. Place
the battery in the tray with the
battery contacts down and
toward the back of the tray.
3. If you need to load label media,
do that now. Otherwise, close
the printer. Figure 3. Battery installation

contacts

8
Charging the battery
(Not applicable to externally powered printers)
The low battery indicator glows red when the battery needs
recharging. The printer automatically shuts off 30 seconds after the
low battery indication. To recharge the battery:
1. Confirm that the battery is installed in the printer.
2. Plug the charge adapter output connector into the printer charge
jack located next to the serial input connector.
3. Plug the charge adapter AC input into a live AC outlet. Connecting
the charger automatically turns the printer on. The CHARGING
indicator glows yellow during battery charging.
Note:
Labels can print during charging, provided the battery does
not become completely discharged. The printer will not
accept data if the battery is too depleted to print labels.
4. Charge the battery for 2 to 6 hours. The CHARGING indicator will go
dark and the READY light will begin flashing when charging is done.
Battery charging will stop automatically after six hours. If the battery
has not achieved an adequate charge after six hours, the CHARGING
indicator will shut off and the LOW BATTERY indicator will begin
flashing. This indicates that the battery is probably defective.
Loading labels or tags
Media is supplied on rolls having an outside diameter of about 2". Two
support arms hold the label roll in place. One arm is spring loaded to
allow the use of different roll widths. To load label stock:
1. Confirm that the printer is off.
Note:
This is a safety measure, to assure that the printer will not
print while it is open. You may leave the printer on during
loading, but take care that you do not touch the printhead.
It may get hot if printing begins.
2. Open the printer.
3. Unwrap the new label roll.
4. Push the spring loaded support arm all the way to the left and
hold it there.

9
5. Position the label roll between the
support arms. Load the labels with
their imaging surface facing the
printhead.
6. Allow the spring loaded support arm
to slide back against the label roll.
The roll will turn on the supports
with slight resistance when the paper
is loaded correctly.
7. Pull the free end of the label stock
until a few inches of stock extend
from the roll. Figure 4. Loading label stock
8. The labels feed through the printer differently, depending on the
label presentation mode. Thread the label stock through the
printer as follows:
• For batch mode presentation: Position the label stock over the
paper door. Close the printer while pulling the free end of the
stock. Turn the printer on and press the FEED button to index
the first label.
• For peel-back mode presentation
(requires optional peel-back
attachment): Raise the peel-back
locking bar until it is horizontal.
Pass the label stock over the drive
roller, then down and behind the
white peel-back roller. The label
stock should extend about ½"
beyond the peel-back roller. Tear
off any excess. Snap the locking
bar down tight against the printer
body, then close the printer. Turn
the printer on and press the FEED
button a few times to confirm that
labels feed properly.

Installing thermal transfer ribbon
(PT422003 only)
The PT422003 must have a ribbon installed when printing thermal
transfer labels or tags. To install or replace the ribbon:
1. Confirm that the printer is off.
2. Press down on the ribbon door’s
back edge and pull it forward, then
swing the door open to expose the
ribbon take-up roll.
3. Open the printer.
4. Remove any exhausted ribbon by
pressing each roll to the left to
release it and then lifting it out.
5. Unwrap the new ribbon roll. The
ribbon is attached to the new ribbon
take-up roll. Do not detach it from the take-up roll.
6. Position the new ribbon supply roll in the printer such that the
ribbon unwinds from the bottom of the roll towards the front of the
printer. Snap the new ribbon roll into place by pressing it to the
left as you push it onto the ribbon hubs.
7. Pull the ribbon over the printhead. Notice that the ribbon’s shiny
side faces the printhead and the dull side faces the drive roller.
8. Position the new ribbon take-up roll under the ribbon door. Snap
the ribbon take-up roll into place by pressing it to the left and
pushing it onto the take-up roll hubs.
9. Turn the ribbon take-up roll until the ribbon slack is taken up.
10. Close the ribbon door and the printer.
Selecting the print mode and index method
The printer supports both black bar and gap indexing. The PT422003
can print in direct thermal or thermal transfer mode. If you are using
label printing software, it should provide a means to set the print
mode and index method.
If you are writing your own software or controlling the printer using
direct commands, you must use printer commands to set the print
mode and index method. Refer to the programming information in the
PROGGDE.HLP file for more information.

Note:
The PT422003 cannot use gap indexing in direct thermal
mode. Only use gap indexing when using thermal transfer
mode.
Printing a self-test label
Printing a self-test label checks the printer’s overall operability. To run
a self-test, verify that the printer is ready to print labels (label media
installed, and battery installed and charged). Then:
1. Confirm that the printer is off.
2. Press and hold in the FEED button, then turn the printer on.
Release the FEED button after the printer begins printing.
3. After a few seconds the printer will print a self-test label. Printing
a self-test label places the printer in hex dump mode. Turn the
printer off and back on again to return it to normal operation.
Important!
Printing a self-test label places the printer in hex dump mode.
The printer will not print labels while in hex dump mode.
Turn the printer off and back on again to resume normal
label printing.

12
USING THE PRINTER
Note:
New batteries are delivered uncharged. Install and charge
the battery for 6 to 8 hours before using the printer for the
first time.
Turning the printer on and off
The printer uses a pushbutton switch for manual power control. Press
and release the ON/OFF button to turn the printer on or off.
The internal speaker will beep once when the printer is turned on and
twice when the printer is turned off. The READY light flashes
continuously about once per second while the printer is on, unless the
battery is charging.
The printer is automatically on if the battery charger is connected. The
READY light is off during charging, and the CHARGING indicator is on.
Feeding blank labels
To feed blank labels:
1. Confirm that the READY indicator is flashing green.
2. Press the FEED button to feed a blank label. Each time you press
the FEED button, the printer will feed an additional label.
Sending data to the printer
To print labels using data sent from a host computer or terminal,
perform the following steps:
1. Connect the host and printer serial ports together.
2. Confirm that the host and printer are using the same
communications parameters.
3. Confirm that the printer READY indicator is flashing green.
4. Send your data to the printer.
Note:
Transient noise or incorrect serial port parameters can cause
a data transmission error. If an error occurs, the printer will
emit one long beep. Re-send your data to resume normal
printing.

13
Automatic power management features
Timed power shutoff
Code Courier features a power shutoff timer to save battery power
when it is idle. When running on battery power and inactive for longer
than a specified period, the printer automatically turns itself off.
Pressing the ON/OFF button will turn the printer on again.
Any printer activity that occurs before the specified time period has
elapsed will reset the power shutoff timer. The timer restarts when the
printer finishes the activity. The timer will not run while the printer is
processing labels, even if printing is paused. This avoids data loss if
you manually pause the printer during a batch mode operation. The
timer is also disabled whenever the battery charger is connected.
This is a programmable feature, and is not activated when the printer
is first shipped. Your printer software may provide control over this
feature, or you can activate it using direct commands. Refer to the
PROGGDE.HLP file for more information.
Low battery power shutoff
Code Courier continuously checks its battery. When the battery is
almost completely discharged, the low battery indicator glows red and
the READY light shuts off. The printer will beep seven times and turn
itself off 30 seconds later. It will not turn on if the battery is com-
pletely discharged or not connected. Replace or recharge the battery if
the printer delivers a low battery warning or refuses to turn on.
Automatic speed control
You can control Code Courier’s print speed via software, but under
some conditions the printer may limit the print speed to maintain good
print quality. The printer will automatically reduce speed if the
battery becomes too depleted to print good labels at the selected speed.
Printhead temperature also affects the print speed. Code Courier
automatically adjusts print speed to maintain high-quality printing
over its specified operating temperature range.
Low speed (1 inch per second) provides satisfactory printing at any
ambient temperature within the printer’s operating range. If you have
selected low speed, the print speed will not change in response to
temperature or battery condition.
Normal speed (1.5 inches per second) provides satisfactory printing
down to about 5oC. If the printhead temperature falls below 5oC, the
printer automatically switches to low speed to maintain print quality.

14
High speed (2.5 inches per second) provides satisfactory printing in
most applications at temperatures above 15oC. The printer will switch
to normal speed below this temperature.
Print speed may increase with increasing ambient temperature.
Normal print speed resumes if the printhead temperature reaches 5oC
and battery condition permits. High speed resumes if the printhead
temperature reaches 15oC and battery condition permits. However,
automatic speed switching will never raise the print speed over that
set by your label printing software.
Automatic speed control does not require any special operator action.
Be aware, though, that a reduction in printer speed may indicate that
the battery needs recharging.
Sleep mode power saver
Sleep mode conserves power by turning off some printer circuitry when
there is no incoming data and no labels are in process. The printer
goes to sleep automatically when inactive and “wakes up” (reactivates
all of its internal circuitry) automatically when there is incoming data
or whenever the FEED button is pressed. It goes to sleep again right
after finishing the requested operation. You do not have to perform
any manual operations to control the sleep mode.
If you are programming the printer or controlling it using direct
commands, you will need to wake the printer up when sending data.
Refer to the PROGGDE.HLP file for more information.
Buffer reset timer
Unforeseen events, such as a break in communications between the
host and printer, can leave the printer in an indeterminate state. Code
Courier uses a memory reset timer to avoid this problem.
The reset timer resets the printer if it starts an operation and does not
receive expected data for a preset period of time. Resetting the printer
allows the printer to go to sleep and clears any graphics data or label
format in process.
The reset timer is an automatic feature and does not require any
special attention from the user. If you use the printer in an RF linked
data transmission system, however, you may want to change the timer
duration. This is a software controlled feature. Please refer to the
PROGGDE.HLP file for more information.

15
ROUTINE MAINTENANCE
Cognitive printers need very little maintenance other than occasional
cleaning. Clean the outside of the printer as required, using a soft
cloth dampened with a mild detergent cleaner.
Clean the printhead if it appears dirty or if print quality is poor.
Printhead cleaning is easy and fast:
1. Confirm that the printer is off.
2. Open the printer.
3. PT422003: Remove any installed
ribbon.
4. If label media is installed, pull it
clear of the drive roller.
5. Using a cloth moistened with
alcohol 99% pure isopropyl
alcohol, clean all dirt and label
residue from the printhead,
paying particular attention to the
“burn line” (this is the thin black
line near the front edge of the printhead.
CAUTION
Do not use any type of abrasive or metallic objects on the
printhead as this may seriously damage it.
6. Wipe the drive roller with the cleaning cloth. You can reach all
portions of the drive roller by turning the printer on, tapping the
FEED button, and turning the printer off before continuing cleaning.
CAUTION
Keep all objects clear of the printhead and drive roller any
time the printer is turned on.
7. Confirm that the slotted index detector hole (located just behind
and to the right of the drive roller) is unobstructed. Clean away
any obstruction with a soft brush if necessary.
8. PT422003: Install the thermal transfer ribbon.
9. Close the printer and resume normal operation.

Extending the life of the battery
The battery supplied with your printer should charge and discharge
satisfactorily many times. Observe the following guidelines to obtain
the best performance from your rechargeable battery:
• Only charge the battery using the charge adapter supplied with
your Code Courier, or use the optional SC5000 drop-in battery
charger.
• If you must store the battery for an extended period, discharge and
recharge it every six months or so. The battery can lose some of its
capacity if it is not exercised periodically.
• Do not recharge the battery prematurely. If you plan to print
several small batches of labels, it is best to print all the labels and
then recharge the battery, rather than to recharge it between
batches.
• Recharge or replace the battery after the first indication of a low
battery condition.
Users who rely heavily on rechargeable batteries should consider
purchasing the model SC5000 drop-in battery charger. The SC5000 is
designed especially for use with Code Courier, and can simultaneously
charge up to five battery packs. It also features a battery conditioning
function to help maintain peak battery performance.

17
WHAT TO DO IF...
Cognitive printers are very reliable, so printing problems are unlikely.
If you do think you have a printer problem, proceed as follows:
1. Confirm that the printer is turned off.
2. Confirm that the printer is connected directly to the host computer.
If there are any switches or other devices between the host and
printer, remove them for troubleshooting purposes. You can
reconnect them later after you resolve the problem.
3. Open the printer. Confirm that it has the right media installed,
and that it is loaded correctly. See page 8 for media loading
instructions.
4. Confirm that the printer has a battery installed and that the
battery is fully charged. If its condition is questionable, recharge it
or replace it with a fully charged, known good battery.
5. Inspect the media path. Remove any obstructions and clean the
printhead, index detector, and drive roller according to the
instructions on page 15.
6. Close the printer, taking care that the media threads through the
printer according to the media loading instructions on page 9.
7. Turn the printer on. Confirm that the printer READY indicator
flashes green.
8. Print a self-test label as described on page 11. The test label will
report important printer setup parameters, such as serial port
settings and the current index setting and print mode. Keep the
test label for future reference.
9. Turn the printer off and then back on again. Confirm that the
READY indicator flashes green.
10. Press FEED to confirm that the printer will feed a label.
11. Review the common problems described in the following section.
12. If these steps do not correct the problem, contact your Cognitive
dealer or our Technical Services Department. You will find
Technical support contact information on page 22.
Note:
The information here assumes you are using label printing
software. If you are programming the printer, please review
the troubleshooting information in the PROGGDE.HLP file.

Printer will not turn on
Pressing the ON/OFF switch once or plugging in the battery charger
should turn the printer on. The printer READY light will flash about
once per second while the printer is on, unless the battery is charging,
in which case the CHARGING indicator should be lit. If the printer does
not seem to power up properly:
1. Check the battery connections for dirt or corrosion. Clean them if
necessary.
2. Check that the printer’s battery connector is plugged into the main
circuit board.
3. If the printer emits a low frequency tone when you try to turn it
on, a memory checksum error has occurred. Contact our Technical
Support Services Department for assistance.
Printer will not turn off
1. You cannot turn the printer off if the battery charger is connected.
Disconnect the battery charger if you must turn the printer off.
2. If you try to turn the printer off and the READY indicator does not
stop flashing and the charger is not connected, the battery is
probably very depleted. The printer may make a ticking sound for
a short while. Recharge or replace the battery immediately.
Printer shuts off by itself
1. If the printer beeps seven times and then shuts itself off, the
battery is exhausted. Recharge the battery or replace it with a
fully charged one.
2. If the printer beeps twice and shuts itself off, it is probably
shutting down in response to the “timed power shutoff” feature.
See page 13 for further information.
Printing stops
If the printer stops printing in the middle of a batch and it has not
indicated a low battery condition, the printhead may have overheated.
This is uncommon, but can occur in extreme conditions. Printing will
resume after the printhead has cooled sufficiently (typically within
about five minutes). This is normal printer behavior and does not
indicate a printer malfunction.
