Cornea Eye I cleaned the dust off the drum, but there are still marks on my copies. There is something on the cornea eye. What can I clean it with so I can get clean copies without the marks. Thanks, JANICE

Re: Cornea Eye

Take the drum unit out and lightly dab the roller on the drum (not the roller on the toner!) There is probably toner on that roller and it will leave black spots on your paper. I'm not a professional so take this from someone who may not know what they are talking about. I just had the same problem though and that's what it said to do in the manual! You can use Isoproply Alcohol (lightly, not soaked) on the qtip. It says to not "rub" as it may damage it so just gently dab.

Step1 Put on your latex gloves to protect the drum from skin oils. Cover a firm, stable working surface with a few sheets of clean newspaper to prevent spreading toner dust over your work area.
Disconnect your Canon copier from its power source and allow it to cool down for several hours if it has been used recently. Locate the access door to your toner cartridge and drum, typically located on the front or side panel depending on your specific model.
Step3 Remove the toner cartridge from its holding tray by lifting from both sides and pulling it up gently. Gently shake the cartridge to remove caked on dust, then place it on top of the newspaper sheets. Using your vacuum's hose attachment, clean away any toner dust from the cartridge's holding tray.
Lift the hinged door behind the holding tray to expose the copier's drum. Turn the spindle to the side of the door to rotate the drum. Apply a microfiber cloth to the outside of the drum as it rotates to clean away toner dust. Continue until the drum is as clean as possible.
Close the hinged door and replace the cartridge in its holding tray, ensuring that it is oriented the same way as when you removed it.
Reconnect your copier to the power source and make a test copy to ensure proper function.

Oce 7051 plain copier has dust or something on one of the rollers - prints have a trail of marks across sheet, repeating every 10 inches from top to bottom of page. Probably need to remove or access...

If the drum has marks on it, you might have to replace it.  Sometimes the fuser rollers can leave marks on them as well.
Check for lines on the drum first.  If they are there, it could need a drum replacement.

If cleaning everything isn't enough, the drum probably needs replaced.

Problem with Konica 7145.. When i make copies it duplicates some lines and reprints them lower on page (more faded) and also the first lines of the copy are blured in a point that they are not readabl

Manousos Xatzidakis:

I would take another look at the drum cleaning blade as well as the CEL and PTL. Any time I've had problems with double images, the drum carriage and parts associated to it have been the problem. I remember one notable case where I removed and shrouded the drum to protect it from light, cleaned both the charge corona and the discharge corona, cleaned the PCL and the PTL of toner dust, vacuumed the drum carriage of toner dust, cleaned the developer unit and replaced the developer. I finally got clear copies and the customer was satisfied.

I have lines on our copies, How do we clean it?

Locate and check the printer drum. You should be able to see the mark that is causing the line on your page. It could be s scratch or a ring of toner that the wiper is not picking up because a nick or something under it. Try cleaning the drum with a very soft dry cloth and inspect it again. If the mark is still there the drum will have to be replaced. Do Not Try To Clean The Drum With Any Type Of Solvent!

When I try to scan I do not get the image in the flatbed, I get a line or something in the file

at the risk of sounding redundant... try cleaning the glass on the scanner sometimes a scratch or dust can be picked up by the intensity of the scanning lamp that the naked eye can not see. as well as clean the backing of the scanning lid for the same reasons just mentioned. if the line fails to go away then unfortunately it is the glass or printer hardware

Printing directly on a cd or dvd

You should clean the white printed marks on the CD caddy. the "magic eye" relies on these marks to accurately assess where the CD is.

If it still struggles after cleaning the white alignment marks, clean the exit rollers with something like windowlene/windex to ensure they have sufficient grip.
