C554 J2002

[Spidula]

Evening all,

Need a little help.

C554 jamming tray 2 A3 booklets J2002 codes. A3 runs fine from tray 1. Very low vol machine. Flashed V68 FW. Took out the feed assembly and stripped the clutch as they are the same as C220 series and they had probs on installs. No joy though. Everything physically looks fine. Was scratching my head after 2hrs so going back with a colleague on Tues next week.

Any of you guys with any info or if had same problem please reply

Thanks

Re: C554 J2002

I have a c554 doing this too, fortunately my customer was happy to leave the a3 in tray 1 and I've not heard back from them since.

It seems to do it on first attempt to feed - subsequent feeds after this error are ok until another tray is used and then its attempted again. Nfi wtf is going on, i have a feeling its because this customer is using exceptionally poor quality paper and the paper from the lct is covering the vertical transport rollers with paper dust. As it jams mainly after paper is fed from the LCT.

Yeh, there was a Sh*tload of paper dust on the take up sensor, but give it a good clean.

The customer is actually saying they preferred their C451. I nearly spat my coffee on her!! Ha ha...

Will let you know if we get something sorted on Tues

Thanks for your input!!

Re: C554 J2002

I have a few C284 /C364 machines with frequently J-2002 /J-9901 happening. after cleaning the vertical transport stays away for a while...
Not the best paper is being used with all machines, but it looks like these machines have very tight timings while feeding from tray 2...
For the J-9901 there's a fix in the latest Firmware (Ver. 68) Still hope there's a firmware fix coming for the J-2002...

Re: C554 J2002

also be aware that the one way spring clutch on the lct vertical transport shaft is an *absolute piece of shit*

if you turn it backwards you will break it and you will get 9901's from tray 3.

you can pack out the vertical transport roller bushings and the clutch with the shim washers from 2 of the roller "support kits".

the clutch is also not orderable as once piece and comes as 3 parts, this is one part among many, that should NOT of been made even more cheaply.

Oh well, keeps us employed.

Re: C554 J2002

Thanks for the info folks

A colleague of mine went to have a look and stuck a whole new feed assy in. Still doing its J2002.

Customer is fairly happy feeding A3 from tray 1 so leaving it at that.

Next time I'm back I will have a look at the clutches you mentioned.

Re: C554 J2002

I seem to recall on the training course someone sarcastically saying about the 454/554, Awesome, another km7145, a machine that's too fast for its own paper path and has regular mysterious jams.

Sounds about right to me now

Re: C554 J2002

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!

Good to hear, can't find it on infohub(EU), we don't get full access here, any chance you would like to share?

Re: C554 J2002

the separation spring ?

I was told in training that was to be used with thin paper.

Interesting.

We have just made a habit of setting up all new machines with a3 in tray 1 anyway

Re: C554 J2002

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

Re: C554 J2002

Having the same issues down here in NZ, This is the first time I've seen this fix but will give it a go if what I did today doesn't resolve it. Changed both feed tyres and the small one way clutches that sit next to the rollers along with changing the Dip SW 145 to hex 02 (mis-match paper feeds through rather than jamming).

Cheers

Wow, how long did it take them to implement this change! And why the FEk isn't it enabled by default.

I wonder how many calls it will prevent with dumbasses assuming the machine is "jamming" because they are feeding an unexpected paper size.

FYI. The dipswitch mentioned is meant to prevent the J99-01 jams which occur with mismatched paper so I dont know if it would cure J20 jams. My team have found the spring to be effective for the J20 problem. Just as a warning though, only change the spring when you have the fault. If you change the spring as a `precaution` you can end up with jamming problems again!!!
