HP LaserJet Pro MFP M426fdn
Microsoft Windows 10 (64-bit)

This problem occurs on HP Laserjet M426 and M428 printers. In the ADF assembly, underneath the ADF scanner, are two free-rolling paper guides. These guides are two rollers with black rubber bands across, across a metal bar. Those rubber bands are a bit fragile - after extended use, we have seen several of them snap and come apart.

 

Once they've broken, the ADF starts misbehaving. Papers will often 'skew' once they reach those guides which can cause partially skewed scans. The pages going through the ADF often get output in the wrong order, or will often catch along edges and push papers in the ADF output tray onto the desk/floor. We would like to acquire replacement bands to resolve this issue, but unfortunately I'm running into a hiccup there.

 

I've read through the HP Laserjet M426 repair manual but I cannot find any mention of these little bands or the rollers/bar anywhere in the manual. I'm not sure what HP calls them (Paper guides? Paper rollers?) nor do I know where to find replacements online. Buying an entirely new ADF assembly just to get replacement rubber bands is a tremendous waste, so any advice we could get on replacement parts for this would be MASSIVELY appreciated.

 

Here's an image of the paper guides/bar with the ADF scanner lifted up.

HP directly does not make those parts available. Maybe someone in third party world, but these small ADF devices are also difficult to disassemble. You also cannot purchase the ADF by itself from HP, you need to purchase a part called and ISA or integrated scanner assembly which is the ADF and scanner together.

If you find the information provided useful or solves your problems, help other users find the solution easier by giving kudos and marking my post as an accepted solution.
