MP C401ZSP J004 issue

[copier tech]

This one is driving me mad!

Paper is not being picked up from tray two (all rollers replaced no change)

If I run the motor for tray 2 & the clutch in output checks the rollers all drive fine!

When closing the paper tray the paper lifts up ok & contacts the first pick up rollers but when trying to print or copy the machine tries to feed but jams every time & paper is still in the tray.

I can’t think what this could be!!!???

Have you updated firmware, just kidding.

I know this is a stretch, but we ARE at the grasping at straws point, right?

Could it be the paper? (Wrong paper type or packaging glue residue on the edge of the stack?) I hope you don't feel insulted but I would now be at the point where I don't take anything for granted and try even the simplest most basic things. I know ALL of us have overlooked something we were absolutely SURE couldn't have been the problem...whether we will admit it or not.

Did you look in SMC where is jam location?

After replacing the feed rollers first thing I tried was a fresh packet of paper & some other colour paper they also had, but exactly the same nothing gets picked up.

I'm thinking maybe a tray lift issue, not enough pressure being applied to the pick up/first roller.

Machine only has 20k its still like new.

Updated the firmware while I was there just in case it was a bug etc.

Yes, as in the title J004 (Tray 2 on Jam.)

Either that or the pick up roller isn't dropping down far enough. You could try swapping feed heads with another cassette and even swap lift motors with another cassette and see if you can pinpoint the problem.

Is the feed roller turning in the correct direction? If the one way bearing is installed incorrectly the separation roller will drive the feed roller in the reverse direction.

I would now suspect the feed head for tray two is the fault. Look at the arm that engages your rollers and make sure the solenoid is either out of position or not pulling all the way. Remove the copier from the paper bank to get a better look at it. (I think that can be done on these?)

Forgot about that but you'd think if the primary feed roller (the one with the one-way bearing) was the culprit that it'd at least pick the paper up. From what I read, the paper isn't moving at all?
