DMP 120  (260-1255)             Selftest               Faxback Doc. # 4416

CARRIAGE MOVEMENT TEST

The Carriage Movement Test allows you to check that the Carriage moves 
freely from one end of the Platen to the other and that the Platen is 
turning properly.

Printing is not performed during the Carriage Movement Test.

1. Set the ONLINE/OFFLINE switch to ONLINE and then set the Power Switch to
   ON. The Carriage will then move right and left performing a Line Feed at
   the end of each line.

2. Turn the power OFF to end the Carriage Movement Test.

SELF-TEST

The DMP-120 has a built-in self-test feature which lets you check the 
printing quality and general printer operation before you connect the 
Printer to a TRS-80. This is a good time to check that the Print Head is
adjusted properly (printing is neither too faint nor smudging) and paper is
feeding properly.

The Self-Test will last for several minutes. It includes the various 
printer font styles, print widths and intensities, and even a dot graphics
sample.

As test printing is 8" in width, always be sure to load the printer with 
paper to cover this before running the Self-Test. 
PRINTING ON THE PLATEN CAN SHORTEN THE LIFE OF THE PLATEN AND PRINT HEAD.

To run the Self-Test:

1. Set Print Function Switch 2 to ON (the up position)
2. Set the ONLINE/OFFLINE Switch to OFFLINE.
3. Turn Power ON.

The Printer will begin printing all the characters that it's capable or 
printing.

4. Printing will continue until you turn the power OFF.
