Solving printer problems
Printer hardware issues
Situation
Solution
The printer makes a noticeable
pop sound when it turns on.
This is normal. The sound results from the printer
mechanism designed to improve print quality and facilitate
the clearing of media jams.
A printer door does not close.
Firmly close the printer doors.
Check to make sure that all of the levers and handles
(colored blue and green) are in the correct position.
The control panel display is
blank, and the internal fans are
not running.
Make sure that the printer power is on.
Make sure that the printer is plugged into a working
alternating current (ac) power outlet.
Press all of the buttons individually to see if one is stuck;
contact your HP-authorized service representative if this
does not work.
The printer is turned on, but the
internal fans are not running.
Make sure that the line voltage is correct for the printer
power configuration. (See the plate next to the power
receptacle on the back of your printer for the voltage
requirements.)
If you are using a power strip and its voltage is not within
specification, plug the printer directly into a working ac
outlet.
The green lever does not rotate
up.
Make sure that the image drums are completely inserted
in the printer and the image-drum door is closed securely.
Make sure that the transfer cleaner is completely inserted
in the printer and latched in place.
Make sure that the transfer roller is inserted completely in
the printer.
Make sure that the image transfer belt is inserted
completely in the printer.
The printer does not print from
tray 2, tray 3, or tray 4.
Make sure that the media tray guides are adjusted
correctly for the media size you are using. (See
“Configure
the input trays” on page 39
.)
Select the correct tray in the printer driver.
Make sure that the optional trays are configured correctly
on the Device Setting or Configuration tab in the printer
driver. See
“Configure the printer and the default settings”
on page 54
Tray 4 does not work.
Make sure that the power cord is firmly plugged in to both
the printer and the power receptacle. Remove and
reconnect the power cord.
If the problem persists, you might need to replace the
cable that connects the tray to the printer.
See “Printer does not print from tray 2, tray 3, or tray 4.”.
