Sub error codes
The sub error codes are helpful troubleshooting a paper path problem. Each
status byte has a different level of troubleshooting value for each area of the
printer. The following table displays up to 8 status bytes of data. Some or all
of these bytes may be used to help diagnose a printer problem. These
status bytes are designed to help isolate paper jams and paper feed
problems in the base printer.
To identify the bytes:
975 Unrecognizable
network port
A failure with the network port.
If the printer is a network model, replace
the controller card. See “Controller card
removal” on page 4-15.
976 Software error in
network port
978 Bad checksum while
programming network
port.
979 Flash parts failed while
