DMP 500  (260-1252)            Self-Test              Faxback Doc. # 4586

The DMP-500 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
printer font styles, print widths and intensities, graphics characters.

Before running the Self-Test, however always be sure to load the DMP-500
with wide paper (15" wide) since the Test prints from one end of the Platen
to the other.  Printing on the Platen can shorten the life of 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. If the printing is too light, set the Printer off-line and gently move
   the Penetration Control Lever towards the paper.  If printing is too
   dark or begins smudging, set the Printer off-line and move the
   Penetration Control Lever away from the paper slightly.
6. Printing will continue until you turn the power OFF.
