Printer response problems
The control-panel display is blank
Cause Solution
The printer power button is in the off position. Verify that the printer is on. Fans may run while the printer is
in standby mode (off).
The printer memory DIMMs (available on the HP Color
LaserJet 3000 and 3800 Series printers only) are defective or
installed incorrectly.
Verify that the printer memory DIMMs are correctly installed
and are not defective.
The power cord is not firmly plugged into both the printer and
the power receptacle.
Turn off the printer and then disconnect and reconnect the
power cord. Turn the printer on.
The line voltage is incorrect. Connect the printer to a correct voltage source, as specified on
the power rating label on the back of the printer.
The power cord is damaged or worn. Replace the power cord.
The power source receptacle is not working correctly. Connect the printer to a different power receptacle.
The formatter might not be installed correctly. Remove the formatter assembly. To reinstall it, align the
formatter board in the tracks at the top and bottom of the slot,
and then slide the board back into the printer. Push the
formatter until you hear the formatter latches click into place.
The control-panel display is difficult to read
Cause Solution
The contrast is too high or too low for the office environment. Adjust the contrast on the control-panel display. See Display

Cause Solution
The printer Ready indicator light is not lit. Press Stop to return the printer to the Ready state.
The top cover is not closed. Close the top cover firmly.

panel display.
Replace the specified print cartridge.
A printer message other than Ready appears on the printer
control panel.
See Control-panel messages.
The parallel port might have an MS-DOS timeout error. Add a MODE command to the AUTOEXEC.BAT file. See the
MS-DOS manual for additional information.

printer control-panel configuration settings.

printer driver (HP Color LaserJet 3000 and 3800 Series
printers only).
Select the PS driver in the software program or printer driver.
