Troubleshooting the Printing System
Preliminary Operating Checks
Prior to troubleshooting a specific printer problem, you should ensure
that:
●
The printer is being maintained on a regular basis as described in
Chapter 4.
●
The customer is using acceptable paper as specified in the
HP Printer Family Paper Specification Guide
.
●
The printer is positioned on a solid, level surface.
●
The line voltage does not vary more than 10% from the nominal
rated value as specified on the Power Rating Label.
●
The operating environment for the printer and paper is within the
temperature and humidity specifications listed in Chapter 1 of this
manual.
●
The printer is never exposed to ammonia fumes such as those
produced by diazo copiers or office cleaning materials.
●
The printer is not exposed to direct sunlight.
●
Non-HP components (such as refilled Toner Cartridges, font
cartridges, and memory boards) are removed from the printer.
Note When moving the printer into a warm room from a cold location such
as a warehouse, various problems can occur due to condensation in
the printer. For example, if the Photosensitive Drum is cold, the
resistance of the photoconductive layer will be high. This will lead to
incorrect contrast. Leave the printer running for 10 to 20 minutes.
