Turn off the printer and check the power cord connections between the printer and the electrical outlet. Then turn the printer back on.
If the electrical outlet is controlled by an outside source such as a wall switch, make sure the switch is turned on, or plug another electrical device into the outlet to check whether the outlet is operating properly.
Your computer may not be properly connected to the printer. Refer to the connecting instructions in the Setup Guide.
The interface cable may not be securely plugged in. Check both ends of the cable between the printer and the computer.
Make sure that your interface cable meets the specifications for the printer and your computer.
If you are using the parallel interface, set the Speed setting (in the Parallel menu) to match the value that the computer requires.
Make sure that your printer is selected in your application software.
The Imaging Cartridge may be empty. Replace it following the instructions described in Replacing the Imaging Cartridge.
Press the On Line button once to put the printer online (the On Line light turns on).
The selected font is not installed in your printer. Be sure you have installed the correct font. See Adding and Selecting Fonts for more information.
Make sure that both ends of the interface cable are plugged in securely.
Make sure you use a double-shielded, twisted-pair parallel interface cable no longer than 1.8 meters in length.
The Image Optimum setting may be set to Auto or On. If it is, certain unexpected fonts may be printed to increase the printing speed. Turn the Image Optimum setting off in the printer driver or SelecType Config Menu.
The emulation setting for that port may not be correct. Specify the correct emulation mode on the SelecType Emulation Menu.
If the printer still does not print correctly, contact your dealer or a qualified service representative.
Make sure that you are using the correct page length and margin settings, such as T. Margin or Text, in your application software.
Set the paper guides to fit the paper size you have loaded.
Make sure that your application software is set for the printer emulation you are using. For example, if you are using the LJ4 emulation mode, make sure that your software program is set to use a LaserJet 4000 printer.
Graphics require large amounts of memory. See Memory Modules for more information.
Settings made in the application software or the printer driver override SelecType settings. Use those settings instead of SelecType settings whenever possible.
Your settings may have been changed by your software program. Perform a factory reset (initialize) with the SelecType Init function on the SelecType Setup Menu. See Using SelecType for more information.
You may not have reset the printer after making settings. Press the ALT and Continue buttons at the same time to reset the printer and enable the new settings.
The Imaging Cartridge is not installed correctly. To properly install the cartridge, see Replacing the Imaging Cartridge.
If you encounter any one of the following problems with your printout, try the solutions listed for each problem.
Lighten the Density setting using the printer driver or the SelecType Config Menu.
Clean the paper path inside the printer with a clean, soft, and lint-free cloth. See Cleaning the Printer.
Clean internal printer components by printing several pages with only one character per page.
There may be a problem with the Imaging Cartridge. Remove the cartridge, gently shake it from side to side, and then reinstall it. If this does not solve the problem, replace the Imaging Cartridge as described in Replacing the Imaging Cartridge.
Install a new Imaging Cartridge as described in Replacing the Imaging Cartridge.
Take out the Imaging Cartridge, shake it from side to side, and reinstall it.

Your paper may be moist or damp. The printer is sensitive to moisture absorbed by the paper. The higher the moisture content in the paper, the lighter the printed output. Do not store paper in a humid or damp environment.
You may not be using the correct type of paper for your printer. If the surface of your paper is too rough, printed characters appear distorted or broken. Smooth, high-quality copier paper is recommended for best results. See Available Paper Types and Printer for information on choosing paper.
Check the amount of toner in the imaging cartridge by using SelecType Toner option in the Setup Menu. If a message on the LCD panel indicates that the amount of toner is low (E* F) or toner out (E F), replace the imaging cartridge. See Replacing the Imaging Cartridge for more information.
Check that the Imaging Cartridge is installed properly as described in Replacing the Imaging Cartridge.
The problem may be with your application software or interface cable. Print out a status sheet by pressing the Enter button on the control panel twice while the printer is online. If the status sheet is also blank, the problem may be with the printer. Turn off the printer and contact your dealer.
