DMP-137  (260-2887)          Printer Selftest          Faxback Doc. # 4014

Performing a Self Test:

To check the printer's operation and print quality, we recommend you run 
the printer's self test before you send any print jobs from your computer 
to the printer. The self test has two modes: black test print or seven-
color test print. Perform the self test according to the ribbon cassette 
you use.

Notes:

* The self test prints lines that are 8 inches long, so you must use 8.5"
  wide paper to protect the platen.

* Do not perform the color self test when you use the black ribbon. This
  could shorten the life of the black ribbon.

Follow these steps to run the self test:

1. Check which type of ribbon is in the printer: the standard black ribbon
   cassette or the optional seven-color ribbon cassette.

2. Load 8.5" wide paper.

3. Set POWER to OFF.

4. Begin the test print as follows.

* Standard Black Color Test Print: Press and hold down LF/FF while you set
  POWER to ON. When printing begins, release LF/FF.

* Optional Seven-Color Test Print: Press and hold down PARK while you set
  POWER to ON. When printing begins, release PARK.

In each test, the printer repeatedly prints the 96 ASCII characters
alternately in draft and near letter-quality (NLQ) modes.

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