thermal head, and the roll paper holder).
To clean these parts, turn off the printer, unplug the AC cable, open the roll paper cover, and
remove the paper dust, adherent glue, or other foreign substance with a cotton swab or cloth
moistened with an alcohol solvent (ethanol or IPA).
If paper dust adheres around the black mark sensor, blow or wipe it off to keep the operation of the
printer normal.
For the locations of each part, see the illustration.
!CAUTION:
❏ If adherent glue is attached, be sure to wipe it all off.
❏ Take care not to injure your fingers on the manual cutter when cleaning.
❏ Before turning on the printer after cleaning, allow alcohol on the printer to dry completely.
!KCAUTION:

Running a Self-test
In self-test mode the printer will perform a series of internal diagnostics, and then provide a listing
of printer settings. 
Having a printed self-test in hand when calling for technical support can help speed the
troubleshooting process.
Use the following procedure to start a self-test.
1. Close the roll paper cover.
2. While pressing the Feed button on the control panel, turn on the printer. (Keep pressing the
Feed button until the printer starts printing.) 
The printer prints out the various printer states.
3. When all printer states have been printed, make sure that the following message is displayed and
the Paper LED flashes.
"If you want to continue SELF-TEST printing, please press Feed button."
The printer is now in the self test wait mode.
4. To start a test print, press the Feed button when the printer is in the self test wait mode.
5. Check that the following has been printed.
"*** completed ***"
This indicates that the printer has been initialized and made the transition to the normal mode.
Resetting the Printer

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 Paper LED is on, check whether the roll paper is correctly installed and any roll paper
remains. (U“Installing or Replacing the Roll Paper” on page 14)
❏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.
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 15. 
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 15.
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.
(U“Installing the Paper Guide” on page 8)
Paper jam
Turn off the power and open the roll paper cover to remove the jammed paper. After that, install
the roll paper correctly. If the roll paper cover will not open, see the section below.
If glue or another foreign substance is present on the autocutter blade, platen roller, or the paper
path, a paper jam is likely to occur. (U“Cleaning Inside the Printer” on page 15)
