General Procedures/Information
5.2.4 Print Engine Controller Test Print
There are three methods to produce a Print Engine Controller Test Print.
NOTE: The System Controller must be installed to enter diagnostics.
1 Enter Diagnostic Mode 2 and then press ENTER. The printer will continue to produce test prints
until you press ITEM UP (2) to stop the test prints.
2 Enter Diagnostic Mode 3 and then press the MENU UP (1) or MENU DOWN (5) key until PRINT
DENSITY ADJUSTMENT is displayed on the LCD. Press the Enter key to produce the test print.
One Print Engine Controller test print is produced.
3 The following method bypasses the System Controller.
NOTE: The System Controller does not have to be in the printer for this method to produce a Print
Engine Controller Test Print.
• Switch off the printer power.
• Short the two male pins of P/J35 on the Print Engine Controller.
NOTE: No damage is caused if the shorting tool comes into contact with the metal parts of the printer
frame.
• Turn on the printer power.
NOTE: P/J35 is a white plug located directly above P/31, the Print Engine Controller-to-System
Controller plug.
NOTE: Each time the two pins of P35 are momentarily shorted together, one Print Engine Controller Test
Print is produced. However, if the pins are held shorted, the test pattern prints continuously.
