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. :)

You need to replace the fuser, a consumable item.
