Service Mode, PJL Defaults
The Service Mode should be used only by authorized service
personnel. While in Service Mode, you can:
• Print a Service Mode Self Test.
• Verify and set the Page Count (the page count also is displayed
on the standard self test).
• Set the Cold Reset Default. (This sets the factory default paper
size to either Letter or A4).
• Set the Demo Page=True/False. Used to remove the Demo Page
option from the self test menu.
• Set the Diagnostic Functions ON or OFF (for software
developers use only).
Since the HP LaserJet 5P/5MP printer does not have a front
control panel, Service Mode and many configuration tasks are
accessible only through software (PJL commands).
The following example shows how to use PJL commands to enter
Service Mode and perform various Service Mode configuration
tasks.
Note
Text is CASE-sensitive in PJL; enter exactly as
shown. The
E
C
symbol stands for the ASCII
escape character (ESC or /027). When the PJL
code is entered, print the data file (or use the
DOS COPY command to copy it to the printer).
Detailed explanations of PJL commands and their functions can be
found in the Printer Job Language Technical Reference Manual
(HP part number 5961-0704).
