Preventing paper feed and paper jam problems
To prevent frequent paper feed or paper jam problems, use this checklist of corrective measures:
When a paper jam occurs, a Jam xxx xxx xxx xxx message appears on the LCD panel. Xxx indicates areas where jams may be occurring, such as LC1 (standard lower cassette) or A (cover A). See the relevant sections for instructions on clearing paper jams.
 | Note: |
 |
|
|
|
These messages indicate that paper has jammed in one of the optional lower cassettes. The standard lower cassette, located directly beneath the MP tray, is always numbered LC1, and any optional 500-Sheet Lower Cassette Units and the Large Capacity Paper Unit are numbered LC2, LC3, and so on from top to bottom.
Follow these steps to clear paper jammed in the optional lower cassettes:
 | Pull out the cassette indicated on the LCD panel. |
 | 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 in the cassette. |
 | Clear other paper jams that are indicated on the LCD panel, until all error messages disappear. |
When the paper jam is cleared completely, the jammed page's print data is automatically reprinted.
This message indicates that there may be a paper jam inside cover A or cover B on the right side of the printer.
Follow these steps to clear paper jammed inside cover A or B:

Make sure you use a double-shielded, twisted-pair parallel interface cable no longer than 1.8 meters (six feet) 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 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 in your application program.
Set the paper guides to fit the paper size you are loading.
Make sure that your application software 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, so you may need to increase your printer's memory. See Memory Modules for information on adding memory modules.
Settings made in the printer driver override SelecType settings. Use your printer driver to make settings whenever possible. See When to use SelecType for more information.
Your settings may have been changed by your application software. Perform a factory reset (initialize) with the SelecType Init function in the SelecType Setup Menu. For more information, see Setup Menu.
