This customer was using 80g but is really cheap sh*t.

This is really helpful thank you.

Re: C554 J2002

Really. Its driving me nuts on one machine. More than 500K on the machine and then it would happen mysteriously.
Having this problem on tray 1 and tray 2. Bypass would feed an entire ream continuously with no problem.

So i will try the springs and the dip switch.

This one gives J9901 and J2002 every 150 pages on standard good quality 80gsm A4. Making me waste Friday afternoons in frustration.

Fixed J2002 on one machine by adding shims to the inside of the door hooks. Never had a jam again.
Fixed one with J9901 by removing and reinstalling the door. Also no more jams.

This is silly. Seems to be a combo @#*$ of different solutions for a stupid problem.
Then its just a couple of these problem children. All the others are rocking on with no problem.

Re: C554 J2002

I've got one doing it now, have we come to a consensus on what the "best" fix is?

Re: C554 J2002

We have 1 BH554e doing this to us!! No 99-01's but getting 20-02 jams quite often. Paper comes out of tray 2 about 4 inches and JAM. We clean that out and away it runs. We saw that the door
appears warped on this one machine, but it is all Plastic. Shimming latch did tighten it up. We have done New feed section and tray 2 feed motor assembly on back. No help from KonMin on this one.

So we can assume you have fitted the low tension spring to the tray, fitted the modified conveyance roller and the modified pulling springs on the side door?
These are all official mods from KM and they do work.

Re: C554 J2002

The only bulletins we have seen state "when feeding from the LCC" PC410. That is not in play. Only tray 2.

Drive roller new ribbed black.
Softer pick spring.
Separation torque limiter likes to seize up.
Feed sensor are better wiped than just blown.
Lubricating feed shafts bushings does improve feeding.
There is foam padded guide on T2 which can be obstructive, remove it along with the self adhesive tape.
If you have T3 LCT the amount of paper being fed throughout vertical tend wear out the mylar on T2 and causing it to curve on the edge inwards the tray 2 causing 2002s.
Depending on paper registration loop adjustments do some magic as well!
Registration rollers can slow down if bushings are not cleaned.
Registration actuator does wear as well. I change it around 1 mil on most machines.
Presume you are using Grey ribbed pick rollers and have the latest firmware on machine.

Forgot to add.

If T3&4 are used there is one way spring clutch which has to have washer and then c-clip.
They like to seize and when cleaning vertical rollers roll the rolls in feed direction as if you turn the other way the spring may come out of position inside the clutch.

Hope this helps!

Update for any of you guys interested on this one.

There is now a tech bulletin out for KONICA MINOLTA AUTHORISED TECHNICAL PERSONNEL. Regarding this problem. You should be able to get it on Infohub.

There is a spare spring mounted on the full feed assy to swap over with the problem tray. Did this today and ran 500+ through tray two with not one jam!

Happy Days

Good Night!

This has worked every time I've tried it!!!
