Horizontal Void or Streak
This is usually due to the cartridge not being installed correctly.
Check the printhead area for obstructions, and check the
mechanical workings of the print cartridge and printhead shutter. If
nothing is found go to “Blank Page” and follow those instructions.
LAN Problems
You cannot find a printer or network problem, but jobs still do not
print.
If the network card checks out successfully, the problem may be with
the hardware or software outside of the network card. Below are
some suggestions to the customer for checking hardware and
software for possible problems. Refer the customer to the
LaserPrinter Network Printer Utility Guide to find the problem.
• Make sure that the desired network protocol is enabled from the
printer operator panel.
• Verify proper print queue and printer driver configuration
• Verify that the adapter port has been associated
• Verify correct installation of software utility
• Single route broadcast not supported across network bridge, if
bridge is used
• Server problem; check print server installation and configuration
using the appropriate system guide to operations.
Light Print
Light print is frequently caused by a worn out print cartridge. Clean
the transfer roll by powering on and off two or three times, leaving
the printer on for about two minutes each time. Other causes are the
same as for “Blank Page”.
Make sure Print Darkness on the customer menu is set to Normal or
Dark. 10P: Increasing the diagnostics mode Print Contrast setting
will darken print further.
