Troubleshooting Jamming and Paper Feed Issues on a Lexmark X264dn

The other day I went on a call for a Lexmark X264 that was getting multiple paper jam errors. The errors were not consistent; the printer worked fine at times but also had days where it was not working correctly.  When I arrived onsite, I printed a few pages and everything looked OK. So, I started looking further.

I removed the paper tray and checked the feed rollers. Then I tried printing again and got some paper jam problems. I removed the tray, again, for further inspection and found the source of the problem—the paper stop in the back of the tray was broken and had slid back so the paper wasn’t sitting up in the tray like it should. I installed in a new paper tray (part number 40X5381) and a few paper feed tires (part number 40X5440) and the machine was back and working the way it should.

Other possible causes of feed related issues are the registration rollers. If you remove the toner cartridge you will see a green and gray plastic piece that covers these rollers. Remove the four screws, pull the cover off and clean the rollers. These rollers get a build up on them and can cause odd feed issues. The media feed clutch that sits on the ACM unit is another part of the machine that I’ve seen cause some intermittent feed problems. This isn’t the easiest to get to but something worth checking out or replacing if you’re not seeing anything else that is the obvious. source of a paper feed problem.

Sticky Situation: Pads on solenoids and paper path sensor flags are causing paper jams!”

Today’s Guest Post is from Cliff Bishop at KIS Computer Center in La Puente, California.

Below is something I have found helpful:

Equipment:  LaserJet II to current machines

HP and other printer makers use solenoids to control paper flow.  To reduce “clicking” they put foam pads on one or both sides of the moving armature of the solenoids.  Over time the pad wears and the adhesive migrates through the pad making the armature of the solenoids stick.  Even a momentary “stick” can cause extra pages to feed or the D-Roller to grab and stop a page.

HP would have us at least replace the solenoid, and in the case of many Optional Tray 3+ products, replace the entire assembly.

Official Solution:  Replace the solenoid.

What I do:
1) remove the solenoid
2) Place clear plastic tape on each side of the sticking surfaces
3) reassemble and test the device

Related situation:
Some paper path flags also use foam pads to keep them quiet and have the same issue with the same solution.
