Re: C554 J2002

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.

Re: C554 J2002

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
Pat

Re: C554 J2002

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.

Re: C554 J2002

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.

Re: C554 J2002

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??

Re: C554 J2002

Its probably popular paper in the 3rd world, you can't please everyone. But KM seems to think they can.

Re: C554 J2002

Japan doesn't use 80gsm paper
all the paper samples I have seen from KM Japan are from 70gsm.

I was talking to our paper supplies manager and the trend for office products is to go thiner than 80gsm
Eg - going to 70gsm means they get more sheets per kilo
Basically more environmentally friendly


Crap for the copiers though
- Thiner and recycled ...what next ?

FYI -Dip SW 145 to hex 02 (mis-match paper feeds through rather than jamming) is only designed for J9901 and wont make a difference for J20-02.
Its more for operator error ...even then it displays a message that's not easy for the user to exit

Re: C554 J2002

I just solved this on a C364. I cleaned the vertical transport rollers and the one-way clutches next to the rollers. The transport rollers took a while to clean, they were really dirty with some black grime/dirt coming off.
This is a machine that's been on site for two weeks with under two hundred clicks, with less than seventy through tray two. After the thorough cleaning 100 A3s went through without any problems.
Talking to KM, they suspect the rollers are coated with something that prevents it from drying out while in storage, but they haven't had this confirmed...

Re: C554 J2002

I just went back to one machine on an unrelated call that was initially having the issue on A3 from tray 2 and had performed the spring swap. It has made a large difference in the quantity of the jams but does not eliminate it completely. I've now moved A3 to tray 1 and that's going to be my permanent solution from now on for all customers.

Re: C554 J2002

We've had two C454's (early ones) for high-volume customers and have been plagued with the A3 jamming in Tray 2 prob (mainly J20-02). With the first one, after trying all sorts of issues, including moving the A3 to tray 3 (but we then eventually had same problems in Tray 2 later with A4 even), we ordered the whole Tray 1/Tray 2 assembly from KM and replaced it. Not a problem since. It's part A5AYR70300 and called "Paper feed assy C454e" and was $302.05 and best 300 bucks we ever spent to end the nightmare high-visibility return calls. The second one has just started to be a huge problem and we will do the same. Note that the new units have been modded from the originals, not just a shaft and frame change but also the rollers and maybe more. If you want to try a cheaper option, there's a parts modification for both Tray 1 and Tray 2 with a new pickup roller. Instead of using the same part number as the feed roller (which is unchanged and still A00J563600) it's now a ribbed roller and part A5C1562200. This was on 9/9/13 and applies to these trays for the C224/284/364/454/554 and their corresponding "e" series cousins. Try the new roller and if there's any probs, highly suggest replacing the whole "paper feed assy C454e" unit to the new and improved one.

Re: C554 J2002

This solution works fine. You can use thick tape or washer or duct tape....This eliminate 2 tray jam C224-C554e series.

Re: C554 J2002

the vertical transport rollers now is changer see the niew machine bh224e b&w;
and we update the printer only with the niew patch GD2-27 .

Re: C554 J2002

Same problem, J2002 on my C554e. I change every parts that 's parts manual say PS19, PS20, CL, Washer on the Cluth. Same problem. But after I see this bulletin pressure spring. I try it and so far it work. The pressure spring is soft, so the feed roller may last to 20K to 30K p/c give or take. I just monitor the copier for now let you know the up date.

Re: C554 J2002

There is a modified conveyance roller for the vertical conveyance on tray 2. It has black ribbed rollers a instead of the smooth grey ones and appears to work well. The only problem is that everyone in Europe wants them so they keep going out of stock!
