HP 1500L LaserJet Problems

[Rick]

We are having trouble with an HP 1500L. It periodically makes grinding noises during print jobs, prints out blank pages intermittently, and isn't printing out all the colors from time to time. The toner cartridges are good and the imaging drum has been replaced.

The person whose printer it is has described the following problems:

*Model: hp laserjet 1500L; printer no.: Q2597A; Serial #: CNGGG11051: when printing b/w eg text the printer will intermittently fail to print a page or two at some point in a sequence of several pages; they'll be blank. When printing color my most recent experience (today) is illustrative: a 3 page sequence of color pics: page one fine; page two missing yellow and blue hues; page three: blank. With the change in drums yesterday grinding has stopped ( or is at least much subdued) thanks for your help.

*This just in: loud grinding during the self-exam sequence; cyan seems to be missing most of the time.

*It's degraded to printing one color per page of a colored job.

Would you guys know what could be causing the problems? If you have any tips on what to check, it would be a great help.

Thanks,

Im sorry, have to say,,,EOL!
The carousel has skipped a few teeth on one side, and is really tough to fix if you are not very good at it. Even then it's a pain. You might be able to push down on the carousel, and rotate the right side to it's timing marks. It is located on the inside notch below the "K". The top drive shaft gears have two nubs that line up with the mark.
Time to upgrade!

That sounds like it would be too involved to attempt a repair, so thanks for saving me the time and trouble.

you should be able to stick a paper clip in the square notch just below where the right side top cover arm is closest to the printer.and raise the solenoid to free the carousel.then turn it by hand til the K slot is facing out.then pull the carousel towards the inside a little til it's gear moves past the white gear.to the inside of it.then turn the white gear til the marks line up.can be easier if you pop off the side and top covers.
