20 Most Recent HP LaserJet 2820 Printer Questions & Answers

This is a classic failure mode of HP Printers. I've tossed out two of them for the same reason, after fooling around for hours and wasting a couple of cartridges. My solution? Buy a different printer next time -- Canon, Brother, etc.

HI, Open the top cover of printer and try to clean up the carousel motor solenoid clutch. There are one foam tape - cean or better replace it. clean or better replace foam tape. (It is just for make less noise.) After that control carousel home position left and right gear home position marks must have same position.

The problem you are having is with a clutch also known as CL2 or T2 Clutch. The part is available through HP at http//:partsurfer.hp.com. Just put in the part number RH7-5335-000CN and it will come right up for order. It cost 26.73 plus shipping.

The disassembly is a little intense but completely do-able with the service manual walking you through it. The clutch is part of the drive assembly on page 366 (#3). The diagram looks intimidating but its not as the full hunk can be taken off and then the clutch removed for replacement.

Here's a free copy of the manual:

I would suggest changing printers. That model was prone to many problems with that being one of them.

Have you tried a new Imaging drum?

you may have to reinstall software. It seems something triggers it to shut off.

Kevin_Trenow is correct with his solution to the HP colour Laserjet 2820 error code 5 problem - Thank you.The symptoms are that the machine turns on but after initial movement of the lighted up scanner, there is a disturbing ratcheting noise as if the scanner is trying to move but can't. The machine comes up with error 5 and suggests turning off and on again - this is a waste of time. 1. The top document feeder is released by detaching the multiplug and simply (carefully) removing the whole section.2. This allows the removal of 8(?) screws from the second layer which contains the glass platform. The screw heads were removed using a star drive, labelled CR-V T10. (Buy Draper 31 piece Precision Screwdriver and Bit set; part no. PSS31)3. Carefully lever off the grey surround with button labels on it - probably between 6 and 8 clips attach it.4. Now lift/gently lever off the glass containing layer.5. Use a spectacle wipe or erquivalent to wipe the glass over the white strip (This is the problem - the scanner light needs feedback from the white strip to end up in the correct position - the 'ratcheting noise is caused as the stepper motor continually moves the head to find the feedback point)NB. The glass above the white strip will look perfectly clean - looks can deceive!6. Replace the glass containing layer, ensuring it is clipped in - don't screw up yet in case more cleaning is required7. Turn on and the scanner light should end up in the required position.8. Replace screws, replace lid, push on grey panel and you should have a fully working machine for the price of a spectacle wipe.

Yes, you will need to replace the drum unit as well. be sure to shop around so you can get the best price because some people mark up the price for that part. You can check the status of your supplies from the printer itself by pushing the "menu" button the printer and scrolling through until you see something about supplies status then press the check mark button.

Refix connector J127 on dc, clean the supply memory contact,switch on the machine remove all supplies, install one by one, check the recognition of supply status, missing all? replace DC controller, only black missing?Replace with another one,check, remain same, observe cartridge seated properly? compare with another cartridge feels difference? check the supply memory properly connecting to the contacts?..any breakage in corosol unit?..replace the corosol..

Do NVRAM Initialization for factory default setting. Press & hold enter & * button then turn on the printer, wait till "permanent storage init" appears on display then release the buttons, wait till ready mode comes, check.. I hope it will help you.. But..all setting you will lost like fax,copy,phone book.. be care full.. Best of luck..

Other than tec guy are not advisable to do this exercise :Corosol align distrubed,open the printer up to corosol mechanism check rotary swing shoft left and right gears, there are markings which was exatly matching with rotary right & left disc markings. If its distrubed print quality issue will comes.
You are facing the same complaint. Before opening the machine ensure that read carefully service manual hp clj 2820/2840.. Best of luck.
