Step 3. Printer and Paper-Handling Devices Messages
Be sure to read the exact text of the control panel message, including the error message number and the text, in order to locate the error message in the tables. This printer has enhanced information in the control panel. Printer messages displayed on the control panel provide five categories of information. Each message category is assigned a priority. If more than one condition occurs at the same time, the highest priority message is displayed. When it has been cleared, the next priority message will be displayed, and so on. The displayed messages and their priorities are:
Printer Status Warning messages Error messages Critical error messages External Paper Handling Device Messages
Control Panel and Event Log Message Format
The format of Control Panel messages is:
13.xy PAPER JAM IN INPUT/OUTPUT DEVICE INPUT/OUTPUT DEVICE CONDITION xy.zz 66.xy.zz INPUT/OUTPUT DEVICE FAILURE
The Event Log messages have the following format:
13.xy zz INPUT/OUTPUT DEVICE PAPER JAM 65.xy.zz INPUT/OUTPUT DEVICE CONDITION 66.xy.zz INPUT/OUTPUT DEVICE HARDWARE MALFUNCTION
For information on the 3,000-sheet Stapler/Stacker, see HP 3,000sheet Stapler/Stacker Service Manual Supplement for Paper-Handling Accessories (C4788-90904).
The following are two examples of Control Panel messages, the corresponding Event Log messages, and what the messages mean. These examples do not show the recommended action to follow to fix the problem. See Printer Message Tables on page 607 for the recommended actions for these messages.
Control Panel Message 13.11 PAPER JAM IN INPUT DEVICE

Event Log Page

13.11 1B

Meaning

A paper jam occurred in the first C-link device configured. It is an input device (2000-sheet Input Tray or 2 x 500-sheet Input Tray) with an error code 1B. This is normally a timeout at an entry or exit sensor.
66.22.09 OUTPUT DEVICE FAILURE

66.22.09

A hardware malfunction occurred in the second C-link device configured. It is an output device (Mailbox) with an error code 09. This is an external memory error.
Be sure to print a configuration page to properly identify the input or output device configured. Notice that the error format only identifies the C-link device number and the device type; it does not identify which input or output device is used in the system.
