Situation/Message Solution
The control-panel display is blank, and internal fans are not
running. Make sure that the MFP power is on. Press all the keys to see
if one is stuck. Contact your HP-authorized service
representative if these steps do not work.
The MFP is turned on, but the internal fans are not running. Make sure that the line voltage is correct for the MFP power
configuration. (See the label on the back of the device for
voltage requirements.) If you are using a power strip and its
voltage is not within specification, plug the MFP directly into
the power receptacle.
The MFP voltage is not correct. Make sure that the line voltage is in the correct range. (See the
label on the back of the device for voltage requirements.)
Messages appear on the control-panel display. See Control-panel messages on page 193 .
Print media is jammed in the MFP. Check for jams. For more information, see Clear jams
on page 194 .
