[Misc] MFP476nw All-In-One Issue with Flatbed Scanner

[rebeltaz]

I have got an HP MFP476nw all-in-one color laser printer that I am having an issue with. All of a sudden, the flatbed scanner on this printer has started acting up. When you first turn on the printer, and it goes through the initialization, it moves the scanner tube back to the home position, but it will keep trying, even after it's there... clicking as the teeth on the belt jump the teeth on the gear. It will stop and try again. It does this several times. Once it gives up and finally boots fully, I can tell it to make a copy and it will make a good copy, so I know that the tube is working. But... once it's made the copy, it starts to pull the sled back to home but stops immediately and never moves back more than a millimeter, if that. From then on, if you try to scan, the sled just stays in one place. The sheet feed scanner works fine. I have to assume that the interrupter disc and the IR detector pair is working since it knows when to stop at the end of the scan, but.... I don't remember that ever emitting visible red light. I could be wrong about that, though. The sled is not hanging on anything. The cables are reading continuity. I am at a loss here. I really don't want to have to replace this printer. Any help or advice would be greatly appreciated!

Any error codes?

Sometimes no. Sometimes (like right now) Scanner Error 17

Well, that is a 9 or 10 year office depot type machine now, might be time for an upgrade. I like the older ones also, the fusers last longer than the M477/479 so I get the reluctance but they aren't really much more than a disposable machine once you start having issues. Last HP MFPs I sold were the M477 due to the cheap aftermarket toner costs. Once all the big manufacturers conspired to make them where you have to use OEM cartridges it wasn't worth the effort, the only money to made is on the aftermarket toners.

Yeah... that os one of the reasons I want to hold on to this printer. I as looking at toner costs and we're talking five times the cost I pay now! Not to mention all of the privacy issues. I'm thinking that the opto interrupter is bad, but... if I can't fix it, I'll just buy a standalone flatbed scanner. I appreciate the reply.
