3. Diagnostic Aids

The printer contains self tests to help find and solve problems. You
need not connect the printer to a computer or terminal to run these
tests.

Types of self tests are as follows:

•

Power-On Self Test (POST)

•

Print Test

•

Hex Dump Mode (a computer or terminal is needed)

•

Serial Interface Adapter Print Test

The following are special machine modes that run when the printer
is turned off and then back on:

Turn the printer on while
Pressing:
