Paper Jamming Questions

How do I diagnose paper jams on HP laser printers? by dpbroda
Posted: 9 Feb 05

There are many things that can cause paper jams in HP printers, and diagnoses vary from one model to the next.  In this article I will discuss some of the most common causes of printer jams and possible solutions.

Where is the paper jamming?

This is the most important question to ask.   

1. If the printer will not pick up paper from tray two or three there are several causes.

Try using a lower weight paper.  HP does not recommend printing a higher weight than 20lbs from and tray but tray one.  

If this does not work the paper rollers probably need to be changed.  These come with every maintenance kit, but most end users do not change them, they just change the fuser.  If you do not have rollers available try cleaning them with a lint free cloth and wipe away any paper dust or other debris.

2. The paper is picked up from the tray but does not make it to the toner cartridge.

Typically this is the paper feed assembly or the registration assembly.  These are not easily replaced and I suggest consulting a professional.

3. The paper gets to the toner cartridge and then jams.

Try replacing the toner cartridge.  Sometimes the drum shutter will get bent and cause jams.  

Check for debris.  If there is debris in the paper path this can cause jamming.  Debris can be a torn piece of paper, a stable or just a build up of paper dust. DO NOT touch the roller.  It will hold the oil form your skin and cause print defects.  

4. The paper enters the fuser, but gets jammed inside.

Unfortunately, the fuser will probably have to be replaced, but check for any debris on the rollers before replacing.  Also clean the paper path with a lint free cloth.  DO NOT touch the rollers.  They will hold the oil form your skin.  

This does not cover all possible causes, only the most common.  For any other problems please post a message and I will get back to you.
