SOURCE: Brush roller lines in feed direction of pages

Maybe the charge roller. Make sure it is very clean. You can also stop a copy before it enters the fuser to rule the fuser rollers out.

Our small office purchased a Canon Imagerunner 2000/1600 copier 4 years ago. Since our last service call, when the drum was changed and the machine was cleaned, we then ran less than 2000 copies. The...


When your drum was replaced did they put in a new drum assy or just replace the drum cylinder? I would purchase a new drum because these are one of the chepest to buy, around $ 80.00. They have a 6 month warranty and around 20,000 copies. I would replace the drum to see if that solves the problem. Before doing that, pull off the left side bypass assy. It is easily removed without tools. You should be able to see the drum and see if the drum is clean. If not, then replace the drum unit assy. Are you using only Canon toner, no other kind of brand will work. Generics should work but they are usually not as good a quality. The volume is very low and that should not be an issue. I believe its suppossed to handle 10,000 copies per month. Cleaning the glass top and below may help. The mirrors should also be cleaned as well. Good luck.

I want now what's Common faults in Aficio 2035


THe main problems are toner spill form drom/dev units ..the transfer on the right hand door will have to be emptied every few months. the paper tray paper stops need to be checked as they come out of place and cause paper jams if not set in place..cahrge rollers can be troublesome if not cleaned every coulple of months and may cause dirty image at the sides or lines on copies..dust on laser **** glass can cause faint on sides of copies.. the fuser stripper fingers tat guide the paper need to be checked for toner under the points to stop paper jams in fuser and the lower guide plate entrance to the fuser needs to be cleaned off every now and then to stop crinklin of paper...apart from that good machine

Magicolor 2400w gives paper jam error at transfer roller, after I cleaned the printer -laser head.


My 2400W was standing a long time without being used, and when I wanted to use it, it made a very faint image and showed "paper jam at transfer roller". Also, the image stayed on the transfer belt, but never got transferred to the paper. I tried a lot of things, nothing worked, but the message from weirdal1968 above pointed me in the right direction.

I eventually scratched / scrubbed / cleaned the copper pad on the left side of the optical imaging drum - this copper pad probably receives the bias voltage for the imaging drum from a springy stainless steel wire. There was some visible darkening of the copper pad where the stainless steel wire touched, this is what I cleaned. And then, presto, problem solved - the image came out great, and no more "paper jam at transfer roller" error message.

Gestetner 3245 dev.bias setting....


Hi how you doing the main problem with changing the dev bias is that the gap between the drum charge and dev bias has been brought closer and so more toner is being put onto the drum for image density.. I take it you have cleaned the optics on the scanner mirrrors and that the laser **** glass has been cleaned as these effect the copy quality too.. if the dev hasnt been changed at the pm intervals it slowly looses its charge holding capabilities.. you should change at least at the 160k marks to keep quality good.. you could also adjust the laser power up so you have a stronger image formation..hope this helps..if you know the machine I would take the laser unit out too and take the cover off to see if there a dust coating in the image mirrors as this can cause faint copies over a long period.. Good Luck A

A copy with a lighter image of the copy on the page


Do printed pages come out better than copies?
If they are the same, you may try another toner cartridge (especially if it is a remanufactured or compatible toner), otherwise, you need your optics cleaned (mirrors and lens under the contact glass)

Gestetner 2722z copier, new drum, new transfer belt, smudges yet


The image is not transferring properly..........

remove and clean all corona wires (thin wires that create the latent image) use a q tip and dip in rubbing alcoholhot

Also make sure the fuser rollers are hot(insert or trick safety switches to determine if the fuser lamps are lighting usually upper and lower

Also check the imaging lamp to be sure it does not have any dark burn marks on it and clean the mirrors and the glass under the coy area
