Diagnosing Paper Jams in HP Laser PrintersThere are many things that can cause paper jams in HP printers, and diagnoses vary from one model to next. In this article I will discuss some of most common causes of printer jams and possible solutions.
Where is paper jamming? When you answer this question you are close to solving problem.
1. If 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 paper rollers probably need to be changed. These come with every maintenance kit, but most end users do not change them, they just change 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 tray but does not make it to toner cartridge.
-Typically this is paper feed assembly or registration assembly. These are not easily replaced and I suggest consulting a professional.
