Hp laser Jet Pro P1606dn 52.0 scanner error

HP LaserJet 2840... | Answered on Dec 31, 2018


It's a problem with the scanner unable to "see" its home sensor. The home sensor is a black & white film strip stuck onto the flatbed glass, just above where the scanner head homes. The printer needs to "see" the two little black 1mm square bumps in the white area. When the scanner head "homes", as it just disappears under the plastic it should move left and right as it looks at the home strip. If it keeps going and chatters at the right-stop it didn't see the home strip.

This can be caused by dirty mirrors, or lens in the scanner head (clean them);
Low or off color light (replace the bulb or high voltage power board on bottom of scanner head);
Broken, cracked, or loose scanner head ribbon cable (replace or repair);
Dirty or crooked home sensor film strip (I had one of these: the black & white film strip stuck to the flatbed glass was slightly crooked, it doesn't take much!)
Dirty slide bar (clean & oil);
Bad stepper motor, bad scanner PCBA (replace).

Either a bad cartridge or your carousel is not synchronized properly. If you just replaced a cartridge that is likely the source of the error. You can find videos on YouTube on fixing the carousel issue.

Hi Sccfire, This apparently is a fairly common problem with the 2800 series printer and associated with connection to a PC using USB. It can only be overcome by manually configuring the printer?s USB port to work in standard mode rather than at high-speed USB2.0 mode which probably won?t be to much of a problem. Here is a link from a support page on HP?s site that should walk you through the process: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00506095 Let us know how it goes and please don?t forget to rate the posting.

Thanks CoolDragon. Ifollowed your advice and eventually replaced it.

After trying to pull out and reseat the fuser a few times (I would even get one or two prints out of it each time), I finally ordered another fuser and problem has gone away. I did google and purchasing site searches (pricegrabber, pricewatch, etc) and found a decent priced site, that also gave discount for your returned bad unit (they gave you so many days to return it), otherwise they'd charge your credit card for the extra dsicount they had origanlly given.

The device has experienced an internal hardware error. Recommended Action
  1. Turn off the power by using the power switch, wait at least 30 seconds, and then turn on the power and wait for the device to initialize.
  2. If the error is still unresolved, contact Hewlett-Packard for technical support to troubleshoot the problem. Call HP for telephone support
