The Test Print Function
The Test Print Function is available in Status Mode when any of the three Ready codes (00, 01, 02) are
displayed. Pressing the Self-Test button (upper right) initiates the printing of a single page and checks all
functions required to produce a printed image. The Test Print is a page covered with vertical lines about
a quarter inch apart.
While the test print is being produced, the display changes as the Status monitor displays the codes for
each function involved in making the test print. If no problems occur during the Test Print operation the
DCU will again display one of the three Ready codes.

5.4.2.2 Diagnostic Mode

Diagnostic Mode enables the individual testing of thirteen different printer functions.
Diagnostic Mode is entered by simultaneously pressing three keys--DOWN, SHIFT, and STOP--at the
time the printer is switched on. If the printer is already connected and in the Status Mode, it is necessary
to switch off the printer, hold down the three keys, and switch on the printer.
When the DCU enters Diagnostic Mode, the readout window displays "00" and all LEDs on the printer's
Control Panel start to blink. The Control Panel LEDs continue to blink as long as the DCU is in
Diagnostic Mode.
