2820 error 2


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 required

7. 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.

HP LaserJet 2840 and the scanner not working it stops suddenly and has some noise it says on the screen error5 I turn it off and again on but still not working, thanks


Scanner 5 error is usually caused by a failed scanner head drive motor. HP does not sell that part by itself, you must buy a new flatbed assembly. Can sometimes be caused by dirty mirrors, check my tips on cleaning the scanner on the 3380 as it is the same procedure.

The bulb in my hp 2820 printer does not move even when am scaning


If the scanner head does not move, you need to check two things:
1) If you look into the flatbed while it IS NOT ON (important there), if the bar is off track, it needs to be placed back onto the track.
2) The motor for the scanner apparatus is dead. Buy a new AIO Printer.

Hp 2820 scanner error 5


I'm not sure if this will help or if this is the same as i had but I had been given A laserjet 2820 which keep't coing up scanner error 5 the chap that had it before me contacted hp service & was told to replace scanner unit which he did & it was ok for a while like 6 months & started then started again.
The problem he had was powered up ok till it came to scanner bulb warming up the scanner unit moves back & forth then try's to escape through the right hand side of case.
This is because it cant see the home position white strip under the scanner glass all you have to do is remove top section of the scanner unit complete with scanner glass & clean the under part of the scanner glass the white strip is located under the wide gray panel as you look down on the scanner glass with the lid up. hope this is of some use. my unit has been working for some time now
