Performing the Self Test
1. Loosen two screws to remove the cover, circuit board B.
2. With the paper loaded, turn on the power while holding down the paper feed switch on the
circuit board. (If the power is already on, turn it off first before performing the self test with
the paper loaded.)
3. The current printer status is printed.
4. When the printing is complete, the message, "Self test printing, please press
FEED button," is printed; then the PAPER OUT LED starts to flash.
5. Press the paper feed button again while the PAPER OUT LED is flashing; then the printing
(for the test pattern printing) is resumed.
Self Test End
1. After a number of lines are printed, the message, ***completed***, is printed at the end
of the self test; then the unit enters the normal operational mode, with all settings initialized.
2. When the self test is completed, attach the cover, circuit board B with screws.
Note:
During the self test, check each LED on the circuit board. If an error occurs during the self test, see the
