We have a large black streak printing down the back of our copies. After alot of copies of something it gets lighter. but the next copy down the road it's worse again. How do we clean the copier to remove it? Ee also tried changing the large black cartridge to see if that was the problem but it didn't work either. Help!!!!!!
This is a fairly common problem. More common when you use junk cartridges from printcountry.com.
1) you will need some cotton swabs, isopropyl alcohol and "canned air" or any pressurized computer cleaner.
2) lift up the top console while the unit is on and wait for the cartridges to reset to the center position.
3)Release the grey lock on the LH side of the cartridges and remove cartridges.
4) take alcohol soaked swabs and clean bottom of ports and nozzles.
5) blow out with air.
6) go into program and run clean and align programs. (if you don't have them go to google and type canon mp830 support)
8) if this doesn't work, give to someone you hate or throw out window.

Open your scanner lid and make sure their is no dirty marks sitting on your scanner glass. Also does this happen on the scanner glass or when using the ADF? If its on the ADF its most likely that the glass is dirty and needs to be cleaned.
Are the streaks horisontal or vertical on the page? What printer? Laser or InkJet? If laser, and streaks are vertical, you might have some dirt stuck in teh tomer cartradge or somewhere along the paper path If laser, and streraks are horisontal, your toner cartridge might be dirty or leaking toner
Most leasing companies will not provide financing unless you have a maintenance agreement by an authorized servicing agent. These parts should be covered under that agreement. If I can help, contact me at www.Xippa.net.
Are you sure this is a Designjet 450 (large format printer) and not a Deskjet 450 (portable printer)? The following assumes you have wispy black streaking on the printed side of the paper. If the streaking is on the back side then post more details of the printer model and the issue.
In either case the most likely cause is a buildup of fibers on the underside of the printheads or carriage, causing wisps of black ink to be dragged on the paper when the carriage reverses direction. You can clean the printer as shown at the following (though the details will be somewhat different for the Designjet or Deskjet....).
Do the lines only show up if you use the document feeder? If so, there is something on the strip of glass where the page is scanned. Open the top to reveal the large glass area. Then open the part where the paper feeds in when using the document feeder. It will flip open from right to left. There are two pieces to this, so make sure you grasp it as low as possible. You should see a small strip of glass. Clean all the glass with a SOFT cloth. Don't spray any cleaner onto the glass, rather, spray it onto the cloth if you need any.
Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.
Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).
Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.
Stop the print with a little practice, half to 3/4 of the way threw machine by opening door at right time. You want the paper to be jammed/stopped after the drum (has image on paper) but before fuser (print should still rub off)
fuser is blue green 300 thingy
If print is line less where stopped then mark is from fuser, replace
If print has line before fuser then it is drum/cartridge
..probally drum..need more info to know for sure, ie you say mark when faxing I guessing you mean receiving, what happens in copy mode is same as printing I'm assuming too
