HP 2840 scanner error 2

Received scanner error 5. Turn off and on worked for a few times. Replaced the scanner assembly. First time on showed scanner bulb warming up, but eventually scanner error 2. Turned off and on - no good. The bulb lights up, but is positioned in the middle of the plate.

Help

Re: HP 2840 scanner error 2

Maverick,
when you replaced the scanner, did you re-install all the cables and the ground wire?
If not disassemble and re-insert and re-assemble.
If the scanner assembly is faulty, then return it for a replacement, HP will warranty all the replacement components.

Re: HP 2840 scanner error 2

Thank ypu for your reply. Yes, I believe I connected all the wires correctly. I disconnected the wires and reconnected and still receive the error. I probably made a mistake by buying it via eBay. It was advertised as new and physically it appears to be new.

Any other ideas? Any tests that I can conduct to locate the problem?

Thank you again.

Re: HP 2840 scanner error 2

Hey Maverick,
it may well be the case that the scanner is faulty, however< i have attached a PDF on printing the config page, then a deatiled report from the printer. Check out those and see what the printer has to say about the scanner, it should run some diagnostics on it and tell you in more detail any errors or error messages that have occured. The last page on the PDF is a NVRAM reset ,this will return the printer to the state that the printer was in as it left the factory, so all you settings, faxes, fax numbers etc will be wiped, this may remove the fault if the error is occuirng via a software clitch / error, or it may do nothing to solve the error if the fault is from a faulty scanner, goodluck, let me know how you go

Rowan:

Thank you for your valuable input. I found the problem - the gound wire in the new scanner assy was not attached properly. I removed and put on a new gound connector and now AOK.

But a new problem. I replaced the Imaging drum and now I am not able to scan. I have pulled it and reset three times - I believe it is installed properly. Help!

Re: HP 2840 scanner error 2

Thank you.

Re: HP 2840 scanner error 2

Hello,

 

I know that this post is very very old but I had the same problem (scanner error 2) and I've found that the flat cable connected to the scanner unit had 1 wire out of 20 interrupted.

 

I've changed the cable and the scanner works fine.

 

Scanner error 2 has to mean something like this: the scanner bulb  didn't reached temperature X in time Y.

 

I hope that someone will find my post useful.
