How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

Turn the printer on, and replace the cartridges if possible. If the carriage moves, but there is still a grinding noise, there may be a paper feed issue. If the carriage will not move, then it is a carriage stall issue.
Open the input tray, and then remove the stack of paper from the tray. Remove any torn pieces of paper, or jammed paper, from inside the tray. Replace the stack of paper in the tray, and then close the tray. Check if the noise comes from the input tray.
The flag located right of the pick-up roller has a fixed position. If the flag becomes stuck or broken, it will produce a 60.02 tray lift error or a “LOAD PAPER” message.
Tray 2 lift error can be caused by a damaged, dislodged cartridge contact in the body of the printer, which would explain why multiple cartridges do not solve the problem. Open the cartridge door, remove the cartridge and inspect the contacts on the left side, they should look the same as the picture below.
Paper pushed too far into the input tray when it is loaded, might feed into the printer incorrectly, causing the paper to tear. Paper stacks loaded into the input tray with too many or too few sheets of paper, might feed into the printer incorrectly, causing the paper to tear.
A clicking sound may occur if the stirring spring assembly inside the Toner Cartridge catches on a rib within the cartridge, preventing the stirring spring and its gear from turning. The resulting click is caused by the drum`s toner drive gear slipping against the stirring spring gear on the Toner Cartridge.
55 Lift Down Coil fault All Models Check the down solenoid and wiring, and the scissor harness for crushed or pinched wires.
Solution. Error 2 is a network error code produced by Windows NT that generically translates to: “The system cannot find the file specified.”
That error code indicates a failure of the yellow laser scanner. Unplug and leave for a few minutes, also make sure you are plugged directly into the wall and not into a surge protector.
Improve printer performance by selecting the optimum paper type for the tray. You can select from the following paper types: Tray 1. [Thin Paper], [Thick Paper 1], [Thick Paper 2], [Plain Paper], [Recycled Paper], [Color Paper], [Preprinted], [Prepunched], [Letterhead], [Bond Paper], [Cardstock], [Label Paper]
When the bushing wear thin, the pressure roller gear rides too low and you`ll hear gear noise because the gears are grinding against each other and not meshing well. To fix this problem, you should replace the fuser and also the fuser drive gear in the printer.
When the bearings start to fail they tend to make a buzz sound. Then they stop working completely and your printer starts giving material movement issues as the extruders overheat. The easy way to test if it is a fan making the noise is to stop the fan turning briefly.

Look for a small piece of paper stuck inside the printer. Try a different toner cartridge. Remove any installed paper feed options. Narrowing the source of the noise to a specific feed option.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
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.

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.
