2. Diagnostics information
Start
CAUTION: Unplug power from the printer before connecting or disconnecting any cable,
assembly, or electronic card. This is a precaution for personal safety and to prevent damage to the
printer.
Use the service error code, user status message, user error message, symptom table, service checks, and
diagnostic aids in this chapter to determine the corrective action necessary to repair a malfunctioning printer.
They will lead you to solutions or service checks, including use of various tests.
Symptom tables
If your machine completes the “Power–On Self Test (POST) sequence” on page 2-1 without an error and you
have a symptom, then go to “Messages and error codes” on page 2-5. Locate your symptom, and take the
appropriate action.
Service errors (9xx.xx’s)
If a service error code appears while you are working on the machine, then go to “Messages and error codes”
on page 2-5, and take the indicated action for that error.
Service error codes are indicated by a three-digit error code followed by a period and additional numbers in the
format XXX.YY. In most cases, five digits are shown.
User status and attendance messages
•
User status messages provide the user with information on the current status of the printer. Ready displays
on the first line of the display unless invoked, and then Power Saver displays. If a user status message is
displayed, then go to “Messages and error codes” on page 2-5.
• User attendance messages are indicated by a two- or three-digit error code that provides the user with
information that explains a problem with a print cartridge, paper jam, option, port, and so on. If a user error
message displays, then go to “User attendance messages” on page 2-5 and “Paper jam error codes
(200-series)” on page 2-9.
