Error Processing
When the printer detects an error, it reverts to an error recovery mode or fault
mode. In the fault mode, the following occurs:
•
The ATTN LED lights.
•
A continuous alarm sounds when the front panel alarm feature is set to
on. (Press CANCL or ENABLE / HOLD to turn off the alarm.)
•
The error log buffer automatically logs the error.
•
The message display shows a message indicating which fault has
occurred.
Four basic error categories exist in the printer:
•
Fatal Errors: problems detected within the internal workings of the
printer. When these occur, printing stops and the printer requires repair.
•
Correctable Errors: errors requiring you to perform some action to
clear the error.
•
Overrideable Errors: errors informing you that printer performance has
decreased for some reason. You can override the error and continue
printing.
•
Non–Intervention Errors: host system errors cleared by the host. These
are logged in the error log. In some, but not all cases, you are informed
that they have occurred.
Clearing Correctable and Overrideable Errors
To clear correctable and overrideable errors, refer to Table 4–3 and follow
the instructions. After clearing the error, complete the procedure as follows:
1. Press ENABLE / HOLD after the error is corrected to return the printer
to the hold mode.
2. Press ENABLE / HOLD again to return the printer to the enable mode.
