Lanier ld520c jams from tray 1

[fixthecopier]

The machine has a total of about 300,000.

The jam is always from tray 1. Jam code 003. The lead edge of the paper comes out and touches the 3 grey rollers on the feed shaft. It may run 10 or 12 sheets before jamming. I pulled the feed assembly from the rear of the machine and changed both 1 way clutches, the spring clutch, swapped the motor and tried different paper trays. Has anyone else had this issue?

Make sure the guides in the tray are OK. It sounds like they may not be aligned properly, or they may be broken.
This might be kind of a long shot, but if time permits you might take drawer 1 completely out of the machine and make sure that the latch on the bottom front right hand side of that drawer wasn't modified stupidly. I've run into a number of LD520cs with that latch broken, and before I knew better even I may have modified them that way. Sorry about that.

Had that one the whole time. That's where I got the info on the clutches. I called Ricoh and all they could come up with was firmware.

If you take the tray out and look on the right hand side of the machine frame, there's a black plastic roller. Check that for a flat spot. That can cause the tray to drop on one side and cause jamming.

To update, firmware did nothing, as expected. I pulled the shaft with the 3 grey rollers out and changed it, no difference. Out of frustration, I swapped the whole right side door simply because of the rollers that contact the grey rollers. So, everything has been swapped.changed parts...

Paper tray and roller
Both 1 way clutches
feed motor
Shaft with feed rollers, 3 grey
Right side door
Torque limiter
Black plastic guide

There must be a loop adjustment, yes? Try adjusting that. =^..^=

Yes there is (SP1-003-001, registration buckle adjustment for tray 1), but it never seemed to do that much good when I tried it. This is more likely something else.

With 300k pages have you tried replacing the tray feed roller and sep pad? The majority of my non feeds on those machines were the guide on your left hand side when you open the tray it should be touching the paper when the spring plate is locked down, most of the time someone moves it to add paper and does not put it back or they mash it to tight and bind paper to the tray lip and paper will jam with partial pulled page.

Check the push switch behind the tray, I would also check the push switch for the right side door, i used to push in on the door while its closed and let go several times, if you hear it beep at you or the display flickers the switch is sending a door open signal if this happens during paper feed it will cause a jam.

You could try swapping tray 1 and 2 around see if the problem moves, if it does then you knows its a tray issue and limits it to roller, sep, spring plate etc. Make sure tray 2 works with tray 1 pulled out if its feeding fine from tray 2 this might narrow it down to switch for the tray or something with the feed unit of tray 1.

I have swapped the tray 3 times. Runs fine from tray 2. I feel like I have overlooked something simple.

After spending a lot of time laying on the floor trying to get the tray 1 feed assembly back in with out pinching any wires, for the third time, I went to put a clutch in a new Konica c454. Unplug the connectors, remove 5 screws and you are holding the combined feed assembly for trays 1 and 2 in your hand. 5 minutes. Just sayin...

Well if it works fine in tray 2 position it must be ok tray wise, i know that spring clutch is a pain for tray 1, #2 is easier to get at but of course 1 usually fails first. That spring clutch would be my only other thought besides a faulty paper end sensor or push switch. You could try swapping the paper end sensors from one and two around and test it, they get faulty and will cause paper out during feeding.

Re: Lanier ld520c jams from tray 1

Well I can close this. I swapped the trays again, no change. I tried the buckle adjustment, no change. One of the other techs suggested doing a memory clear. I scoffed. In 18 years I have never fixed a jam that way. I cleared the engine, no change, just as I thought. I cleared the printer and copier and that goddamn thing has run about 250 pages so far and is still running. I don't get it, but I am happy it is running. Of course it makes me look bad after fighting this beast for 2 weeks, but shit happens.

Generally speaking, I like to clear function memories before I clear system or engine memory.
