SOURCE: FUSER ERROR

I just reviewed both of the above fuser issues (50.2 & 50.3). Both are highly likely (even if recently replaced) fuser damaged. I have included below a link to a free HP service manual for your machines. Start on page 309 using a volt/ohms meter to test the fuser. To address the "Guest" inquiry regarding the HVPS, there is a separate HVPS however please be aware that it is not part of the fusing circuit in this machine. If anything it would be the LVPS (Low Voltage Power Supply) however very remote. Odds are maybe 1 in 200 on your best day. I'd put 10 fusers in the machine before I bought 1 LVPS. This machine is known to eat fusers. The HVPS and LVPS at this time are just about bulletproof. PLEASE TRY TESTING THE FUSER AGAIN USING THE MANUAL PAGE 309 TO 311. If your really want the power supplies though, they are on the part number list at the end of the manual. I just looked it up and we have repaired 74 of machines to date with not one PS ever used. 59 of the 74 have been for fuser issues.

Here's the manual link:

Hope that helps you both. :)

Scanner error 5 on HP Color Laserjet 2840


Scanner Error 52 is a hardware error. If turning the power off , waiting 30 seconds and turning it back on does not solve the issue the the scanner assembly might need to be replaced. Another thing to try is make sure the printer is plugged into the wall not into a surge protector. Aside from that you may need to have the scanner assembly replaced.

I am getting scanner error 5 massage on hp 2840


A tech needs to look at it. It could be as easy as just reseating the 4 wire bundle connector that comes off the scanner and connects to the formatter.
But, in any event a tech has to check it out.

Scanner Error 5 "error message" on my all in one


I had this problem and it had to do with the scan bulb head not recognising the marker. My temporary fix until the bulb is replaced is to turn the printer off, open the top (ADF and all) with the gray button on the right so that it's slightly raised and then switch the printer on. When it comes up, just close and print/scan/copy as usual. Apparently the spring in the arm warped the interior surface where the head moves and it can't line up when it's closed. Hope this helps.

Engion error


Based on prior experiences, it looks like it is the laser scanner that is bad, I have had some engine board go out too, but it should be 1 of the 2.
