DMP-135  (260-2866)            Selftest               Faxback Doc. # 4330

The DMP-135 has a built-in self-test function which checks the print quali-
ty and general printer operation before you begin using the printer. 
However, this test does not check the printer port.

Before running the self test, be sure to load the printer with 9.5-inch-
wide paper. The self test prints from one end of the platen to the other 
and the wide paper protects the platen.

    CAUTION: Printing on the platen can shorten the life of the platen
    and the print head.

To run the self test:

1.  Turn off the printer.

2.  Press and hold [LF/FF] while you turn on the printer.

3.  When you hear a beep, release the button. The printer prints the 96 
    ASCII characters programmed into the printer.

During the self test, the DMP-135 prints alternately in standard font for 
five lines and correspondence quality font (Courier) for five lines in a 
continuous pattern.

Press [ON/OFF LINE] to temporarily stop the self test. Press the [ON/OFF
 LINE] again to resume the test. To end the self test, turn off the 
printer.
