Line down center of page.

I have a line down the center of the page when I copy a document. I have changed the DRUM and also the Ink Cartridge. This line only happens when I copy something myself - not on any incoming faxes. Thanks, Sherrey

Re: line down center of page.

Hi Sherrey, I think I can help! If you open the ADF cover where you insert your pages to make a copy. You will see a scanner glass about 1/2 inch wide and runs across the width of the printer. You can take a soft towel and some glass cleaner and clean the glass. There will probably be some white build up that looks like white out on the glass just make sure you clean it very well. I hope this helps!!!!

Copying problem

Vertical lines on the copy usually indicate a dirty drum or Corona wire. The Corona wire should be cleaned each time you replace the toner cartridge. This is done by moving the Corona tab back and forth across the wire several times to clear it of debris. You may also want to check the drum for debris. Holding the copied page to where it feeds out and lining up the line or mark on the page will give you an idea as to where the dirt may be. Best of luck with your printing issue.

When printing dark line down copy

A line down the copy can come from a dirty document scanner lens.
Usually white out or wet ink will smudge on the document scanner. Opening the document cover check the scanner for a dirty glass. Some document feeders have the white roller on top of the small glass window. They have delicate plastice retainers that hold the roller on both ends. Extra care needs to be taken if this roller is removed.
Clean the roller and the glass with wet towel. Shine a flashlight on the glass to see if there are anymore black marks on it.
Use the finger-nail to run across the glass and make sure no debris is on it. Even a spot can make a line on the copy.
Also, a bad fuser roll can cause a black line on the copy. A defective drum unit can cause a line on the copy as well.
If all else fails place a Xerox service call for this problem.

Canon B640 printing problem

The scanner lamp is not working. When making a copy, the lamp lights the source document, so if there is no light, the source document 'looks' black. Your machine will need to be serviced.

Fax machine

Ok , I want to clarify. You have a line on all printing? When you receive a fax, when you print and when you copy?
If so, you need to replace the cartridge with the drum.

If It only is when you fax out and make a copy, then open the scanner and clean the strip over the CCD assembly in the scanner.
What happens is that something, Whiteout, ink from a page windes up getting on the scanner glass and as the original passes over it, it scans as a line and shows up on the paper as a line.

Large grey streak down center of page

It is the fuser at rear giving you grief! The upper heat roller has a teflon coating that wears away allowing toner to stick to roller and smudgin prints as they pass threw it. The fix is to replace fuser assembly, take to brother dealer to fix.

You can prove it to yourself by timing the print to stop mid way threw machine then remove print cartridge and look at paper, you should see a image is good untill it hits the fuser,( pre fused image "rubs off" paper.) If you have changed drum and toner thats all it can be. They all do it in time.

Fuser is hot bit at rear, pull out drum and look in the back with a small torch you will see upper heat roller is worn, guestimation $90 for fuser plus labour to fit.
