Control-panel messages

Be sure to read the exact text of the control-panel message, including the error message number (not all error messages display an error number) and the text, in order to locate the error message in the tables. The control panel for this MFP stores enhanced information.

Not all possible error messages that can appear on the control-panel display are listed in table 18 on page 120. If a message appears that is not in this table see the HP LaserJet 4100 series printer service manual for more information about control-panel messages.

The messages displayed on the control panel provide six categories of information. Each message category is assigned a priority. If two or more conditions occur at the same time, the highest priority message appears. When it has been cleared, the next priority message appears, and so on. The displayed messages and their priorities are:

●Status messages— Status messages communicate the current state of the MFP to the operator.

●Warning messages— Warnings are messages that are important enough that the user must acknowledge them, but not serious enough to make the MFP stop the printing process.

●Error messages— Error messages communicate to the operator that some action must be performed, such as adding paper or clearing a jam.

●Critical error messages— Critical error messages communicate MFP failures to the operator.

Hint

If the control panel display is blank or messages appear garbled, see “Basic troubleshooting” on
