Re: Dark Copies

Jim, A couple of things: 1. OEM (Canon original) toner cartridge or remanufactured/compatible? The first place to start is always with the toner cartridge when image problems occur. Pull the cartridge out and draw back the drum cover. Check to see if the drum is a nice "clean" blue color or if the lines and spots are on it like you described. (These two areas should be handled by someone with experience in copy service) 2. The next thing would involved cleaning under the copy glass. Build up from dust, etc causes a "fogginess" that makes the machine try to adjust the intensity of the exposure lamp to conpensate for this. 3. Also could be a bad upper fuser roller if you started having any paper jams when to paper exits.

Are the dark spots random and moves location with every copy or are they at exacly the same place on every copy? Random you will need to remove the drum/toner and use a blower to clean the inside of the machine,failing that replace the drum unit.If the spots don't move clean the top glass.Let me know

Our Gestetner DSm645 gives Dark Copies..........

Sounds to me like the drum needs replacing, and likely the developer too. There is probably a haze of toner still on the drum. You can check by opening the right side cover and looking at it. Is there toner on the drum (green cylinder). It may not be too obvious depending on how dark the copies are. GENTLY wipe a tissue across it after making several copies - it should be clean if the drum is functioning properly. If it is, it could be the fuser that is wearing out, but I'm leaning toward the drum. As I said, if you need to replace this, it is a good idea to do developer at the same time, because these machines tend to be a little sensitive.

Copier too dark

Did you clean the lens and the mirror under the lens cover? If so, There is a VR behind the front cover of most small Xerox machines. One VR makes the image darker/lighter and one VR changes the lead edge registration.

I have a dark line across copies

Whats the make and model of the copier?
One culprit might be the drum.  If you can take a look at the drum from your copier and you see black lines on it.  It could be scratches on the drum or it may need a new cleaning blade to clean the toner off the drum.

Dark edges

It depends... never use a Reman cart in these machines... only use sharp...especially if the machine is under warranty.

Does this happen when,
Using the Doc Feeder
When making copies from the Glass
Or when you print from a computer (assuming you print from a PC)

If you print something and this happens then it is inside the machine
Probably toner or developer dumping...

Take a few pieces of large white paper and cover the entire glass surface... make a copy is the line there? If so see the answer above... if not then close the top and make a copy with no paper on the glass... is that black line there.. If so then your top needs adjustment...

One more test
If you make a copy using the doc feeder, this black line only occurs when making copies with the doc feed, clean the **** glass, and try again...
