Troubleshooting

Printout is faint
When printout is faint, adhesive glue or another foreign substance may be
present on the thermal head, platen roller, or paper path of the printer.
In such case, first clean the thermal head by following the instructions
described in "Cleaning Inside the Printer" on page 12.
If the print quality does not improve, clean the platen roller and paper path of
the printer by following the instructions described in "Cleaning Inside the
Printer" on page 12.
Printed character size is not appropriate for 40 mm/58 mm width paper
When using 40 mm/58 mm width roll paper, if the printed character size is
not appropriate or if the printout does not fit within the paper width, the
paper guide may not be installed correctly.
See "Installing the Paper Guide" on page 11 for installation instructions.
Error LED on or flashing
❏ Check to see that the roll paper cover is closed and check the Paper LED.
Close the cover or replace the roll paper if necessary.
❏ If the printer has been printing a lot, the thermal head may be hot. Wait
for the head to cool. Printing will resume automatically.
❏ Open the roll paper cover, and check to see if the paper is jammed. If a
paper jam occurs or if the roll paper cover will not open, see the section
below.
❏ Turn the printer off and back on. If the LED is still flashing, notify your
manager. The printer may require servicing.
