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

Thanx!

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!!!

Thanks,

We knew it wasn't related but as we were getting desperate we thought it might change the sensitivity of the timming overall.

Rollers and clutches no joy as suspected so was going to change the spring but instead the customer wanted to change the paper trays around so will have to wait for another machine to test is out on.

Thanks again for the help.

Hi All

Has anybody come up with a fix for this problem- changing the spring has not worked for us on several machines -364, 454.

We've heard rumours of a new modified feed section supposed to be coming out but seen nothing as yet.

Cheers

The spacer/washer mod (for tray 3/4) spring clutch can also improve J20-02

Its a really strange Jam and not an easy one to narrow down.

putting the lighter take up roller pressure spring in place on tray 2 has made a massive difference in my experience. But I simply recomend to customers to put the a3 in tray one for "enhanced reliability"

the 2002 jams are caused by the takeup roller pressing hard on the paper stack, causing friction between the fed sheet and the sheet below after the takeup event has finished and the paper is being fed by the vertical transport roller. the small vertical transport roller slips momentarily causing the jam. The standard spring puts too much pressure on the stack and the lighter one has worked for me.

also, the tray 3 / 4 / lct vertical transport clutch crappiness of design plays no role in this jamming from tray 2. The tray 2 vertical transport roller does not use on of those clutches.

The crappiness of the paper plays a role too, as some customers i've never had to do anything and never seen the jam at all.

The C224 series paper feed assy for Tray 1 and Tray 2. Has been designed to feed thin paper (52 -
59gsm) although this type of paper is not popular in the UK this design change may affect some paper
types at 80gsm. And jam code 20-02 or 10-02 may happen.

But, but, but..... Is it REALLY saying that tray 1 and 2 are being designed for thin paper less than 80gm? Who's using this lightweight paper anyway??
