HP Color LaserJet 8500

Experienced technical support provide their insights in answering this question :
HP Officejet is by far one of the frustrating piece of equipment I have ever owned. I bought it as unused in the package, at that point no warranty left. less than 6 months and 500 pages the white cog gear wheel broke. Luckily with instructions in this site I manage to glue it back together. Then I bought new ink – problems started as they were not original HP 30$ per cartridge. Ordered originals (here in China), took over one week to get them. Then found out that printhead needed to be replaced => more than 100$ spent. Still constant problems: If my wife kids print, I need to be stand-by as you never know what happens. Really an Office level equipment. After cleaning one paper jam I broke the encoder tape, took me another 4 hours to get it fixed. Then broke the cog gear again and got it displaced. Another 4 hours. Only reason I am not throwing this s***t out of window is that there are still ink left. Luckily this drinks them like a horse, for sure I will no more buy new ink. I will get a new laser instead, and not from HP. About cog wheel fixing: make sure that the white wheel is positioned correctly so that the small torx in shaft goes into the slit in the white wheel. When fitting the black cover back, make sure that the white washers on both sides fit into to slits of the black cover. Good luck.

How to Identify and Fix Common Problems ?

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

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.
If your printer has a paper path cover behind the carriage, remove the cover, and then remove any jammed paper. Pull out the input tray, and then remove any jammed paper. If your printer has a bottom cleanout door, carefully lift the printer and look under it, and then remove any jammed paper from the bottom cleanout.
Check inside the printer for any debris that might be causing paper jams. Turn off the printer, and then unplug the power cord from the electrical outlet. Remove any paper from the input tray. Open the rear access door, and then clean the paper feed rollers with a lint-free cloth lightly moistened with filtered water.
If the paper is even slightly askew, the rollers will pick it up a little crooked, and — guess what — the crooked sheet will immediately get jammed. So even though there`s no paper stuck when you start printing, the loose paper guides are ensuring that a sheet gets jammed whenever the printer starts doing its thing.
If your printer keeps jamming, you should know that the most common cause of a jam is misalignment of the paper. Paper needs to load in smoothly, completely flush with the tray. Overfilling the tray is a great way to ensure you will be spending some personal time getting to know the inside of a 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.
Step one: Perform a power reset

With the product turned on, disconnect the power cord from the rear of the product. Unplug the power cord from the wall outlet. Wait at least 15 seconds. Plug the power cord back into the wall outlet.

your pickup roller is dirty and the printer can`t grab a piece of paper. it will say paper jam when it does this. get a drop of dishsoap and clean the pickup roller of your printer with this. scrape at it with your fingernail to get the roller clean and wipe it off with a damp washcloth.
During a print job, the printer stops feeding pages, and a Paper Jam error message displays on the printer control panel. This indicates that paper might be jammed inside the printer. note: Paper jams can be real or false. The printer might report a paper jam even when there is no jammed paper.
Step one: Perform a power reset

With the product turned on, disconnect the power cord from the rear of the product. Unplug the power cord from the wall outlet. Wait at least 15 seconds. Plug the power cord back into the wall outlet.

Slide the paper all the way into the printer. The leading edge of the paper will stop at the Paper Drive Roller. Locate the Paper Sensor/OOPs sensor on the right side of the paper path. It can be seen from the top of the printer with the Top Cover open and has red, black, and blue wires attached to it.
Step one: Perform a power reset

With the product turned on, disconnect the power cord from the rear of the product. Unplug the power cord from the wall outlet. Wait at least 15 seconds. Plug the power cord back into the wall outlet.

Paper Jam and carriage jam code when nothing is jammed
