DMP-204  (260-2883)              Self Test            Faxback Doc. # 4250

Running the Self Test:

To check the printer's operation and print quality, we recommend you run
the printer's self test before you connect it to your computer. This
self-test function has two test modes, depending on the ribbon cassette you
use--black test print or seven-color test print.

Follow these steps to run the self test.

1. Check to be sure which type of ribbon cassette is in the printer,
   standard black or optional seven color.

2. Load standard 8 1/2" wide paper.

CAUTION: The self test prints lines that are 8" long, so you must use 8
1/2" wide paper to protect the platen and print head.

3. Set POWER to OFF.

4a. Standard Black Color Test Print

    Press and hold LF/FF while you set POWER to ON. When printing begins,
    release LF/F.

4b. Optional Seven Color Test Print

    Press and hold PARK while you set POWER to ON. When printing begins,
    release PARK.

    The printer repeatedly prints characters--alternately in draft and
    letter-quality (LQ) modes. If you are performing the color test, the
    printer alternates the colors printed.

5. To end the self test, press ON/OFF LINE or turn off the printer.

If some of the characters are blurred or if the printer is light, adjust
the print head. If this does not correct the problem, try removing and
re-installing the ribbon.
