Laserjet M603DN tray 2 not lifting
ANSWER : I had a similar issue with a M602, though it’s the previous generation machine they are close in design. This one kept saying tray 2 lifting but there was not a sound of the motor even trying. My first thoughts were replace the lift motor then DC controller but it was replacing the formatter that fixed it after other parts made no difference.

Tray 1 (upper tray) paper feed problem
ANSWER : There is no way of adjusting the distance of lift. Could be that the pickup roller is worn enough that it will pick up a sheet that is higher, but not one that is lower down. You can look at the end of the roller that first makes contact and see if it is worn smooth.

Paper jam in tray 2 (but no paper pulled from tray) also M476DN models
ANSWER : Isopropyl alcohol is not recommended for rubber rollers. It dries out the rubber and hasten it’s cracking and breaking. It will do nothing to restore the grip. Those rollers are really hard to replace. It would be easy if that dumbass secondary menu really worked. None of the techs I’ve spoke to ever got into it. Everyone I know sends a print job and listens for the roller to rotate into position where you can pull it off.

HP Laserjet 2200, Tray 2 Pickup Problem, Gears Clicking
ANSWER : Definitely not a solenoid problem. I’ve worked on tens of thousands of printers and never replaced a single solenoid. You probably knocked something loose when you installed the pickup roller. Maybe something to do with the gear on the end of the pickup roller shaft. You’ll need to take the gear assembly off to be able to see it.

Optional 250 Sheet Feeder Tray (Q5931A – Tray 3) Constantly "Jams"
ANSWER : You don’t say if the paper moves at all. That’s key in determining the cause. If it’s not moving, then try swapping the rollers with tray 2. If it is moving out of the tray, then that would indicate there is some obstruction it is hitting on its way out of the tray. Hard to troubleshoot remotely when one doesn’t have specific details since we can’t see what is occurring.

Paper tray 3
ANSWER : What usually happens in this instance is that the access flap to the left of the pickup roller pops up. This blocks the tray from opening. The only way to fix it is to look in from the back of the tray with a flashlight and get something thin and long, maybe a wooden ruler? Reach in and push down on the flap until it locks in place. If you’re not sure what I’m referring to, you can pull out and look at tray 2 for guidance.
