ImagePress C1. I just completed a print job - imaging a Florescent Label stock with black print. When I ran the next job, I saw that there was a band of toner going the length of the sheet. Not sure if this was a result of the label stock introducing some foreign matter into the imaging system or not. It looks similar to some type of squeegee smearing the toner on a drum or something. See attached image. When I print just black, the black is in the stripe, when I print full color, all colors are in the stripe. The toner stripe is obviously too thick on the sheet, as it rubs off fairly easily on the stripe. But the regular type does not rub off. Any one have an idea?

Re: Excess toner band on page
Sure, that it is toner and not developer? as long as the fusing unit is ok, which you can check visually, i would investigate the area around the drum unit and the dev units carusel for foreign material. also check the primary corona grid.as it rubs off fairly easily on the stripeIf sometimes you feel a little useless, offended and depressed always remember that you were once the fastest and most victorious sperm of hundreds of millions!Comment

How would I turn potential control off?
The sample I scanned was on regular paper. I also ran the same job from the RIP on regular paper and the banding was there.Comment

Re: Excess toner band on page
-------
make sure the ARCDAT Patches are being cleaned by the Secondary Transfer Roller.
one of the pressure plates on the Secondary Transfer Cleaning Unit may be cracked. A cracked pressure plate will cause insufficient pressure on the secondary transfer roller cleaning brushes. This resulted in poor cleaning
There are five pressure plates on each end of the Secondary Transfer Cleaning Unit. The part number for them is FC7-0863-000.
have u removed the Transfer Belt to inspect/
ITB Cleaning Assembly 1 FM2-2455-000, ITB Cleaning Assembly 2 FM2-2456-000, Inner Transfer Roller FC6-1545-000 and Secondary Transfer Cleaning Brushes FC6-1645-000 (2)
have u run some test prints in service mode to inspect ?

Re: Excess toner band on page
Well, I dug into the guts of the machine and I found a lot of excess toner building up on the rollers. The pictures give the best description of what is going on. Any ideas on this one? Thanks.

------------------
CHECK if the arm on the ATR Shutter that sits above the turret had come out of the socket andis rubbing against all or one of the developers.
M Developing unit??
Check your M Developer Cylinder Retainers-
when was the last time u did a developer change ???**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment

Re: Excess toner band on page
The arm of the shutter has not come loose and does not rub against the developer cylinders. Also, the cylinder retainers are secure. I noticed that there is a lot of toner on every developer cylinder. I have not changed the developer in the 1 1/2 years I have had the machine. The buildup on the cylinders contains all of the toner colors, and it is concentrated in the same areas on each of them as in the pictures.Comment

Re: Excess toner band on page
Hi Victoryprinting,
I assume that your machine has not been maintained for long time.
As you may know, this machine use only one drum and 4 developing unit rotate around drum so toner usually drop out.
You have to do maintenance more frequently in comparison with other model.
Back to your case, please clean all developing unit, patch image sensor, machine inside... re check starter lifetime and replace if it reach end of life.
This problem is quite common on C1 machine

Re: Excess toner band on page
Thanks so much for helping me narrow down the issue with the C1. I did finally narrow it down to the developer unit. It appears that toner had dropped down and was building up on the plate at the bottom of the rotating developing unit. My best guess is it was "scooping up" excess toner on the developing rollers as it rotated around. This caused excess toner to pile up on all of the developer rollers, and subsequently was transferred to the drum, then to the transfer belt. Perhaps there was some debris in one of the developer units and was depositing toner. I gave it a good internal cleaning and all is working fine now. Now I just have to replace the transfer belt, as I discovered some imperfections with it - but that is quite an easy fix compared to this last issue.
Thanks again for your time in giving me some direction!Comment
