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 soft-
ware for possible problems. Refer the customer to the LaserPrinter
Network Printer Utility Guide to find the problem.
•
Make sure the network protocol you want is enabled from the
printer operator panel.
•
Verify proper print queue and printer driver configuration.
•
Verify the adapter port has been associated.
•
Verify correct installation of the 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”. See
“Blank Page” on page 2-14 .
Make sure Print Darkness on the customer menu is set to Normal or
Dark. Increasing the diagnostics mode Print Contrast setting will
darken print further.
PostScript emulation output may appear lighter than PCL emulation
output or a test print; this is not a defect. Verify on the Print Test that
the print is too light before performing service.
Network Card 977 Errors
All network card errors are recorded as 977 in the error log. If there
are 977 errors in the log, POR several times and take the appropri-
ate action for the displayed error code.
