Error Ranking
The LCD shows only one error at a time. If multiple errors occur simulta-
neously, the errors are prioritized to determine which error is displayed.
Table 6–3 lists the error priority ranking. The highest priority error appears at
Level 1. When two or more errors with the same priority level occur, the
LCD panel displays the error that occurred first.

Error Log
The CT Test called “Print Error Log” produces a record of the number of
times each error occurred in the printer since the last time the Error Log was
cleared. The errors are stored in the Error Log as a two–digit code. Printing
the Error Log produces a listing of the two–digit code, the error message, and
the number of occurrences of the error since the last time the Error Log was
cleared.
To clear the Error Log, refer to “Clearing Correctable and Overrideable
Errors” on page 6–35. Table 6–4 explains the two–digit error code used in
the Error Log.
