Kyocera 7002i thick solid black line

Re: Kyocera 7002i thick solid black line

Hi, I too would like to add to this thread, having this issue arise on both a TA8002i and now a TA9003i both mcs experiencing this black vertical black line issue AFTER 1st PM kits fitted. Having already been down the line of replacing drum, transfer unit, dev and finally drum drive as previous suggested posts, with No resolve, I decided to fit an old style transfer [no yellow dot] unit that I had kept from an old TA8001i pm and found this cure my issues on our test device. All along I have believed this to be a faulty PM unit as only started as I said after 1st 600k PM kits fitted, so I believe its an earthing/grounding issue with these new type units. Our mc is still running old type transfer unit under test and runs 3-4k per day on delivery notes/invoicing, hoping it holds out as these old units used to run on and on, still working even when split or ripped.. Hope this adds some light to this issue out there

That would be something to definitely look into, we have replaced the transfer belt twice but I am not sure we still have the original one. We are replacing the laser tomorrow and I'll look around for the original unit. Thank you for the input and experience with it.

Well we replaced the laser at the suggestion of someone here and it's still randomly doing it. I'm at wits end with this thing, we have replaced everything single thing that has anything to do with making a print.

From everything I've read on this thread, I'm inclined to think it may be the new style transfer belt that you installed. Did you ever find the old one? Good luck.

No we don't have it anymore but we do have one of the newer ones we put in it. What I am going to suggest doing is take the one we have here and put it in another customer's machine that does not have this issue and take their transfer belt to the customer that does and see if the new machine now has the problem and if the other machine stops doing it.

That's a great idea.

Here's my line of thinking on your problem. The machine was working fine before you replaced anything? Correct? That leads me to believe that the problem was introduced into the machine with one of the items that you replaced. The best solution, IMO, is to put each old item (one by one) back in the machine until the problem goes away. Of course, you can't do that if you don't have the old parts. Again, best of luck.

Maybe some of new transfer belts are factory flawed.

Went back and read the first post. Looks like I'm wrong. The problem started before anything was replaced. I think I'm right about that?

I went back and looked at our records and it is hard to tell when it first started because we could never reproduce it while we are there but I'm thinking it did start after the first maintenance kit we put in. When it originally started doing it the problem would only happen once a week if that many times so it's hard to pinpoint the actual day it started.

If that's the case, you now have a plan of attack. Whatever was replaced, go back and replace each item one by one with a known good one until the problem is resolved. Be sure to keep us up to date.

@Billy, I'm sure he will.

@Necrocannibal, I like your plan. Seems out of frustration you have pulled another rabbit out of your hat. Imho that makes difference from good techs to great ones.

Lol, thanks. We are kind of down to grasping at straws with it but this seems like the most logical straw to grasp at

Re: Kyocera 7002i thick solid black line

today i received brand new bulletin for Iris high systems.
Looks similar to this problem.
Haven`t seen it on this range up to yet, but maybe it can be helpfull in your case also, i think.

Looks like we may have a winner Kyo. Good to know even working on other brands.

Looks similar but different machine. I haven't called it yet but we swapped the transfer belt from a different machine that had the old style belt without the yellow dot on it and so far we haven't had any issues. I was going to give it another week or two before saying it was corrected but will definitely update this thread when we call the customer next week and ask how it is doing.

Re: Kyocera 7002i thick solid black line

I've got a 7002i that is on it's 2nd transfer belt assy for the same issue. I did not notice the crooked lines in the feed direction before/during the gray band. And the band is 100% K solid fill, not gray. The odd part is that the transfer belt change cures it for while.

I'm ordering the ferrite core now. I'm not entirely sure it's the same thing ... but I'll give it a go. =^..^=
