Question about HP LaserJet 2420 Printer
I see the top roller (it's where the paper comes out) is malfunctioning.
It doesn't roll anymore. I looked the gears on the left side of the printer & fuser, it seems loosely connected which I think is the cause.
My problem is I don't know how to dismantle the printer to replace the gears inside especially on the top roller.
Except for the fuser assembly, I know how to dismantle it to replace its parts.
Pls help...... :(
Here's a link to the complete service manual. The 2400 series isn't known to have problems with output gear problems. Most of the time the problem is with the geartrain itself. Below the service manual link and there is another link that addresses geartrain issues. The gears they are showing and discussing are also known to cause top end (exit) jamming. The article walks you through the gear replacements.
Hope that helps you. If so hit me with a FIXYA.
