Re: raised image on copy ir9070

Check your paper settings. If you are running a thicker paper stock through the machine and haven't set the machine up for that, this problem is likely to occur.
Also, this problem can be caused by a worn out or defective fusing unit, but that will cost you money to fix. Checking the paper settings is free - do that first.

You should also check the colour composition of the text, I've often seem where the composition of the text may be over saturated with high color percentages, especially black. You'll need to go to the application and and try reducing the color compostion of black. Common problem with graphic software, the application could be using high concentrations of cymk for example, say 50 % coverage of each will produce a stunning black, but at 200% coverage. The device will not be able to fuse that much toner. I suspect this is your issue, as you can feel the text raised of the page, a sure indication the color composition is set too high.

Roho: This one is B&W.

Smels like high temp on fix unit like Iowa say.Check paper setting and fix temp in s.mode.
Can be also a worn fixing unit but to be sure post a pic please.
Check test prints from service mode for some difference on the letters.

Me bad, I saw the description of the symptoms and locked in on common problems like that I've seen before. Still raised text draws my attention.

Re: raised image on copy ir9070

i forgot something when the image faintly appears on third sheet it as sending 1 set of 5 sheets or 10 sets of 5 sheets consecutive , the last set will always be clean as you could ask for..using canon toner as well. will check fuser , this has been going on for a while,ran 6 case of paper yesterday.. if you turn dens up to nine it will make image trace almost go away ,in fact it did for those 6 cases..started a new run of different books and it showed back up can't make it go away..dens adjustment doesn't seem to affect anything at all, no matter what it is on.this is the percetage adjustment correct??

Re: raised image on copy ir9070

Wow...mass confusion, What is the paper weight? Is it in specs of the machine? Is it being registered properly? If you can feel it on the paper obviously it is not fusing properly. You changed upper and lower fuser rolls and bearings. I did not see bushings(plastic collars). Make sure both have their flanges(large side)installed toward the front of the machine. Older versions of the service manual have incorrect diagrams. Is the web advancing properly? The one way clutches go bad and won't advance web. Make sure that the static eliminator in the fuser under the lower fuser roll is good and making contact. If the little hairs are all hacked up and missing replace it. I have seen this cause dirty running fusers on 105s and 7105s also. Ensure that the metal contact inside the rear heater lamps cap is bent out and will make good contact with the metal washer/collar on the rear of the upper fuser roll. This is where the bias is applied to the upper fuser roller. One last thing...when it does repeat the image, run it on 17 inch paper and measure distance between repetitions. Take this measurement and divide by pi(3.15 roughly) and this will tell you the diameter of the roller that is causing the issue. Simple math. Keep us posted
