We just replaced HV1 and brought the machine up and made 100+ black copies with no problems, but when making multiple color copies, we have what looks like a repeated image on the lead edge of the copies. The image looks like a light and smudged repeat of the pattern from earlier copies. Any ideas?
hi, I like to see the sample of the problem that you have.
usally on tech rep i run stibilizationa nd inilization first. i run this maybe 2 times, you want to also make sure gradiation is acurate and fine, do gruiation, then i would go to half tone and cahnge the setting for 99, usally the default is 255 then you can really see half tone for each color should be lighter when reunning it at 99. this test usally tells you which color is giving you problem.
this has fixed many prblems specially with doule image and color smuged.
the half tone seeting will go back to deafult of 255 when powering off or going out of the tech rep.
I still want to see the sample.
good luck
The sample is attached, I hope. Any advice?
I saw the sample, the only time I seen this issue is when the fuser unit was faulty. this is someting like oily stuff on the paper. never seen this before.
but thoes adjustment that i just mentioned will help to isolate the problems.I usally go to tech rep and do graduation first, then i run stibilization few imes, after that you need to run half tone test and change the adjustmet to 99 and check for each color and print the page, it prints solid color for c,k,y,m and the color is light because the half tone is change from 255 to 99. try and see if you have same issue.
I try to get some mor info for you. make sure your paper size also is set correct for the tickness, if it's glossy or regular, there are mny issues with selecting correct size.
Like I said before, make up your mind which thread you are going to use and STAY WITH IT!!!!
Cleaning bias on the belt "might" be weak. To verify, print a few pages of the same image...about 5, and when the second sheet is exiting, force a jam...just open a door. And then remove the transfer belt and inspect. If you see a latent image on the "cleaned" portion of the belt (just after the cleaning unit), this is the issue.
10.6.2 Transfer Belt
A. Cleaning Bias
Functions • To set the level of transfer belt cleaning bias independently for each process speed.
Use • When the image pattern is not completely removed, it strengthen the transfer belt cleaning bias in order to make the cleaner more effective.
• For each processing speed, positive and negative output values can be set.
Setting/ Procedure
• The each default setting is 0.
-5 to +5 (step:1 *)
*: One step corresponds to 5μA.
If that is not the problem, paper weight might be. If you are doing card stock or anything like perhaps 80lb glossy text, you need to set the paper weight accordingly. The fusing unit sets its temperature based on this and will cause ghosting if not set to the correct weight.

you can get help from any expert and any certified filed engineer, every one welling to put out thier experties and some poeple may have more experience. I thinlk stirton.m getting it to complecated and it is not that complecated when you think of it. I personaly think the papaer could have
issue and you can alway stop the paper before exit to the fusing sextion. I think thoes setup and adjustment that i send you will determine the cituation a little. I always use these test before start repalceing parts and get down to changing transfer belt,fuser,print head and so on. I hop you get this going without any expensive part repalcement. let me know what happens.good luck

It's not that complicated. Adjustment of the cleaning bias is related to the transfer belt itself and is a VERY common issue with this series of machine. I immediately recognized that problem when I saw the image he provided. If you look at the image where the defect is, you will see that the ghosted image is obviously smeared and limited. Fuser ghosting does not do that. Fuser ghosting leaves an almost exact duplicate of the previous image, albeit a much lighter version.

Paper was 20lb. plain. The transfer voltage adjustment did the trick. Thanks for all the help. Will post if other problems surface.
