This message indicates that a paper jam may be occurring in lower cassette 1, 2, or 3 (LC3 appears if the optional Large Capacity Paper Unit is installed).
 | Pull out the indicated cassette (lower cassette 1, 2, or 3). |
 | Carefully remove any paper you find jammed inside the cassette or printer. |
 | Remove the stack of paper from the cassette. Even its edges by tapping the paper on a flat surface. Then reinsert the stack into the cassette making sure the paper is evenly aligned and rests below the maximum paper mark. |
Make sure you are using the correct paper size and that your paper meets the specifications for this printer.
 | Push the cassette back into the printer. |
 | Clear any other paper jams that are indicated on the LCD panel, until all jam messages disappear. |
 | After that, if the control panel still indicates LC1, LC2 or LC3, completely remove the indicated cassette. |
 | Carefully remove any sheets that have fed part way into the printer. |
 | Reinstall the removed cassette. |
|  | Caution: |
| | If you completely removed a cassette, be sure to put it back into its original position. Changing cassette 1 with cassette 2 (or cassette 3, if installed) causes improper paper feeding. |
When the paper jam is cleared completely, the jammed page's print data is automatically reprinted.

| | Note: |
| | If the On Line light is off, press the On Line button to turn the power on. |
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 computer.
If you are using the parallel interface, set the Speed setting (on the Parallel menu) to match the value that the computer requires.
Make sure that your software is properly set up for your printer.
The Imaging Cartridge may be empty. Replace it as described in Replacing the Imaging Cartridge.
Press the On Line button once to put the printer online (the On Line light comes 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 person.
Make sure that you are using the correct page length and margin settings, such as T. Margin or Text, in your application program.
Set the paper guides to fit the paper size you are loading.
Make sure that your software program is set for the printer emulation you are using. For example, if you are using the LJ4 emulation, be sure that your graphics software is set for a LaserJet 4 printer.
Graphics require large amounts of memory; see Memory Modules for more help.
Software programs override SelecType settings. Use software 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. For more information, see SelecType Settings.
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 one of the following problems has occurred in your printout, try the solutions listed for the 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, 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. Printing is sensitive to moisture absorbed by the paper. Do not store your paper in a humid or damp environment.
Install a new Imaging Cartridge as described in Replacing the Imaging Cartridge. Then print several pages to check the print quality.
Remove the Imaging Cartridge, shake it from side to side to distribute the toner, and wipe the bottom of it with a clean, dry cloth.
Clean the paper path inside the printer using a clean, soft, and lint-free cloth.
Clean internal printer components by printing several pages with only one character per page.
If the problem remains, replace the Imaging Cartridge as described in Replacing the Imaging Cartridge.
Your paper may be moist or damp. Printing is sensitive to moisture absorbed by the paper. The higher the moisture content in the paper, the lighter the printed output. Do not store your 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 Paper Specifications for information on choosing paper.
If after checking the SelecType Toner option in the Setup Menu, the Toner message indicates that the amount of toner is low
(E*F), read Replacing the Imaging Cartridge.
Check that the Imaging Cartridge is installed as described in Replacing the Imaging Cartridge.
The problem may be with your software program or interface cable. Print out a status sheet by pushing 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.
Darken the Density setting using the printer driver or the SelecType Config Menu.
Your paper may be moist or damp. Printing is sensitive to moisture absorbed by the paper. The higher the moisture content in the paper, the lighter the printed output. Do not store your paper in a humid or damp environment.
Take out the Imaging Cartridge, shake it from side to side to distribute the toner, and then reinstall it. If the problem persists, replace the Imaging Cartridge as described in Replacing the Imaging Cartridge.
The Toner Save mode may be on. Turn off the Toner Save mode using the printer driver, OneTouch mode 2, or SelecType Config Menu.
The Density setting may be incorrect. Change the Density setting on the printer driver's Panel menu. (You can also change this setting from the printer's control panel using SelecType. For details, see SelecType Settings.)
If the problem persists, replace the Imaging Cartridge as described in Replacing the Imaging Cartridge.
Toner may have spilled in the paper feed path. Remove the Imaging Cartridge and then clean the paper path of the printer using a soft, lint-free cloth. See Cleaning the Printer for more information.
| Warning: |
| When opening the printer, do not touch the hot areas indicated on the caution labels inside cover A. |
Be sure you have selected the proper paper cassette in your software.
There may be no paper in the lower cassette. Load it with paper.
Make sure that the lower cassettes are properly installed as described in Installing.
Make sure you have not tried to load a cassette with too many sheets of paper. The cassettes can hold a maximum of 500 sheets or 1000 sheets (depending on the cassette) of 75g/m2 (20 lb) paper.
The Page Protect setting in the printer driver or SelecType may need to be changed.
You may not have enough memory installed. If you are printing at 600 dpi, printing at 300 dpi may solve the problem.
