A piece of paper stuck in the paper tray or inside the printer can create a paper jam. Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again. Turn off the printer, and then disconnect the power cord.
Loading paper that is stuck together, frayed, curled or bent can cause a jam. Overloading the paper tray, loading different thicknesses of paper in the tray or using paper that isn`t appropriate for your particular printer can all result in a jammed printer.
Low-quality paper leaves an accumulation of tiny paper bits often referred to as “paper dust” inside the machine. This “dust” is one of the top causes of paper jams. More dust means more jams. Besides jams, the dust also contributes to poor-quality prints and causes machine parts to wear at a faster rate.
Frequent paper jams most often result from improper use. Make sure to load the paper correctly and use the right paper size as well as the correct toner or ink cartridges for your printer.
With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet. Remove USB cable, if present. Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

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.

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.
HP LaserJet 4200 paper jam fix
ANSWER : Yes, thank you! You did a thorough post! If your still hacking away at HP’printers you will know that unfortunately HP kept using that type of solenoid with the “Sticky Mess” on all of their new Equipment. I use this method almost everyday (without removing the actual solenoid). I’ve replaced so many I got carried away and now, I sell a solenoid repair kit! It’s for those people that like convenience. I provide a professional supply of perfect material with sticky back tape pre-cut to exact dimensions! All in a little kit. I have install videos, (I don’t charge for that I believe in the Do-it -Yourself approach.) Sorry for the sales pitch… but here is my link.
