HP Laserjet 6MP wont feed paper

ANSWER : I had a similar paper pickup problem on laserjet 6mp. The printer would go through start-up sequence fine but when it received a print job you could here the main gears/rollers turning but no clicking from paper pickup solenoid, then eventually error lights would come one . I incorrectly assumed it was an error with the paper pickup mechanism and wasted a whole day taking the printer apart and replacing the paper pick mechanism. Long story short, if I had bothered to figure out the secondary error light codes from the start, I would have realized it was just a bad fuser and would not have wasted so much time.

ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.

Paper Jam 13

ANSWER : Sticky paper pickup solenoid. Since MF tray doesn’t use it, it works fine. Solenoid is located on right side of printer at the end of the paper pickup roller shaft. You need to remove the solenoid, take the plate and spring off the top and then scrape off the gooey residue that’s causing it to stick. Then you get a thin piece of sticky backed felt and put it on top of the metal base. You can find some at the local hardware store, they’re used on the bottom of chair legs.
