DMP 105  (260-1276)             Selftest               Faxback Doc. # 4309

The DMP-105 has a built-in Self-Test feature which lets you check printing
quality and general printer operation before you connect the Printer to 
your TRS-80. This is a good time to check that the Print Head is set 
properly (printing is neither too faint nor smudged) and that the paper is
feeding correctly. 

The Self-Test will last for several minutes.

Before running the Self-Test, however always be sure to load the DMP-105 
with wide paper (9.5" wide) since the Test prints from one end of the 
Platen to the other. PRINTING ON THE PLATEN CAN SHORTEN THE LIFE OF THE 
PLATEN AND THE PRINT HEAD.

To run the Self-Test:

1. Plug the Printer into and AC power outlet.

2. Set the ON-LINE/OFF-LINE Switch to ON-LINE.

3. Set the Power ON/OFF Switch to ON.

4. Press the ON-LINE/OFF-LINE Switch to set it to OFF-LINE while the Carri-
   age is moving toward the left. The Printer will begin printing rolling 
   ASCII 96 characters in Standard 10 CPI mode.

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