❏ Check to see that the paper roll cover is closed and check the PAPER

❏ If the printer has been printing a lot, the head may be hot. Wait for the
head to cool. Printing will resume automatically.
❏ If the autocutter is jammed, turn the printer off and then back on.
❏ If the paper roll cover will not open, see the section below.
❏ Turn off the printer and then turn it back on. If the LED is still
flashing, call your supervisor or a service person.
Paper jam.
Turn off the power and open the paper roll cover and check for a paper
jam. If there is a paper jam, remove the jammed paper and follow the
instructions in the Installing the Paper Roll section to prepare the printer
for printing.
The paper roll cover will not open.
Turn on the printer and remove the cutter cover. To remove the cover, use
a tool such as a screwdriver, and insert it into one of the slots indicated by
circles in the illustration below and push the cover upward. After
removing the cutter cover, use a ballpoint pen or tweezers to turn the knob
in the direction indicated by the arrow until you see a triangle in the
opening.
