I did clean out the dev. section and change the toner and problem solved. Funny, I just got a call from another customer today who buys their toner on-line. They have exactly the same symptom. This...

That's what I thought. I've seen Katun toner work fine in multiple machines so I figured it must be something else. Confusing why it is bad in this machine and not the other ones. But I'm going to...

I am working on a KM2550. I installed an entire PM kit but the copies have a lot of dirty/dark background and there's somewhat of a 1" or so darker band on the back and maybe a somewhat darker 2"...

I have 2 km1810 copiers and both have j98 error codes. Has anyone had experience with this error? :confused:

I am servicing a customers KM-C2630D and after running a couple of months fine it started giving an error to reset the yellow toner unit. We'd take the toner unit out, shake it and it seemed to help...

Thanks, I'll try blowing it out better!

I have continually gotten J98 code. The Intravia manual says "BD LASER" problem, not paper jam. ???

I've got two Copystar 1810 copiers that I bought off lease and they came in with toner and developer all over. I cleaned them up but now they feed paper, go through the motions of making a copy once,...

Thanks, I'll try that. I appreciate the response!:)

What fixes error F-51-4?

Please tell me what fixed the F-51-4 error. I have a customer with that error on a Konica 7033 and I hope it will go easy for them. They can't afford to replace it or pay...

What would you scrub it with, (mag roller)?

You are right, they are all just over three years old. I only sell them with 50,000-120,000 copies on them, (very low count). That's what makes it hard to put a full PM in them. I did a full PM on...

is V s g G =grid (maybe)

What sim raises the transfer current? I've got the same problem at a church up here. Someone said sim 101 but that shows TC = 120 value. I don't think that value is the current rating, (or is it)?

I have quit a few of these 3 year old "off lease" machines out there now. I still have trouble with "not so dark" blacks.
In the manual it says which way to change Dev bias, Dev duty, Dev Sbias and...

I'm going to go try "all that jazz" today!
I bought several of these KM3035 copiers and got some generic toner cartridges with them. Any problem using the "generic" to "Redevelop" the dev. section...

I've been selling quit a few of the 3035 copiers. Several don't have very good blacks on the copy. I've cleaned the charger and transfer roller and "cleaned up" the developing section. I've used the...

I had exactly the same problem 6 months ago. I just ignored/forgot about it.
Thanks for the "heads up"

I am working on a 3035 and the second side of any duplex copy is "washed out", faded, (like real bad developer) but any normal one sided copy is fine, except for the fact that the Katun toner is...

Howdy!
I'm working on a Konica 7040 with 489,000 copies on it. It gets an error F-28-1 but the customer says they can run about a thousand copies before it does it again. My "Intravia" book says...

I usually use Intravia manuals to repair most copiers. I recently started specializing in KM/Copystar copiers, (2530, 3530, 3035, etc...). I buy them "OFF LEASE" and clean 'em up and send "em out. ...

I have been servicing copiers for 25 years and I am very good with computers. I just haven't got down to business with hooking up copiers to the customer's network. Is there a shortcut for learning...

A church customer of mine in So Bend, IN area has 2 Ricoh dig. dupl.s for sale. Any one interested? They have 6 color master/drum units.

I've got a Canon Color IC2100? Got any use forr that?

Thanks for the help. Yesterday before I checked this forum again I decided to change drum units from a known good machine. That solved the problem so I took the old drum unit apart and cleaned it...
