DMP 400  (260-1251)            Self-Test               Faxback Doc. # 4568

The DMP-400 has a built-in self-test feature which lets you check 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 or smudging occurs) and if the 
paper is feeding properly.

The Self-Test will last for several minutes. It includes the various prin-
ter font styles, print widths and intensities, graphics characters.

Before running the Self-Test, however, always be sure to load the DMP-400 
with wide paper (15") 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 an AC power outlet.

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

3. Press and hold the RESTART Switch.

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

The Printer will begin printing all the characters according to the Font 
Style Selection Switch (Rotary Switch).

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