Possible Solution
•
Re-establish a Bluetooth connection with the
mobile computer or scanner. For help, see your
mobile computer user's manual or
Bluetooth Communications" on page
•
Make sure the mobile computer can print to a
known good printer.
•
Print a Bluetooth test print page to make sure
that the mobile computer discovered your
printer. For help, see
page 27.
•
Make sure the printer is in Ready mode.
•
Fingerprint users: adjust the media constant/
factor and contrast (-10% to +10%).
•
IPL users: adjust the media sensitivity setting
(-10 to +10).
•
ESC/P users: adjust the Media Sensitivity
command or the Set Dark Adjust command. For
help, see the ESC/P Programmer's Reference
Manual.
•
Check to see if the printhead needs cleaning. For
help, see "Upgrading the Firmware" on
page 45.
•
Check the battery date. If the battery is a few
years old, the shortened life may be due to
normal aging.
•
Replace the battery.
•
Make sure that the blue light is not blinking. If
it is, make sure your printer has media and that
the media cover is closed.
•
Make sure that you can advance media by
