Question about Xerox CopyCentre C20 Black and White Copier

Blank copies down the centre of the page

I have a copy centre c20 and i am getting a blank copy down the center of the page this error only occurs when the machine has been on for a few hours (4 - %5). turn the machine off for about 15 to 20 min the problem goes away and then comes back after a few hours. i thought of the corona wire but if it is the wire would the problem be constant.

    i know this is a bad response but i don't see the corona wire i know on other copiers it was a matter of sliding it out and cleaning it but on this copier it just has the drum cartridge and the tone cartridge. it looks more like a laser printer than a copier.

My c-20 copier will not print from glass. prints blank pages. will only print the ones placed on the feeder.


I know this silly, but you put the originals on the opposite end of the glass. I don't mean to insult anyone, but I don't know your experience with this machine.

The fact that it copies thru the feeder, tells me the copier is ok. The doc feeder uses the same optics.

hope this helps

I have a Xerox Copycentre C20. There is an error message reading Scanner Locked. It will only print blank copies


What you want to do is look on the bottom of the scanner.
On the bottom of the scanner you will see one and only one green latch. It is about 2 inches long an a half inch wide.
Turn the machine off and puch the latch in toward the back of the machine, then pull it out toward yourself untill it snaps forward.
Once you get it released, lift your feeder and look on the left side of the glass. You will see 2 phillips screws. Remove those, then take that 1 inch glass and white plastic surround off. Gently slide the scanner to the right until you slide it under the glass. Reach down and squeeze the tabs on the side of that latch and pop it out. You can just leave it out, but I would recommend taking some good tape and covering the hole to keep moisture and dust out of the scanner.
That latch is for shipping purposes only. So it will not have any effect on the machine unless you are planning on moving it in a truck or car a long distance, And if you are, just pop it back in and latch it. But that IS your problem. You hit that latch removing the copies from the output area.

Blank strip down center of page


It's hard to say when I don't know what machine you have, but it could be the toner cartridge. If you have a cartridge pull it ou shake it gently and try another copy.
Good Luck

XEROX C20 - Leaves a blank stripe down the side of the copy


Yeah the c20 is not sturdy at all. But that aside. Some things to do.
1, Unplug the machine, remove the back cover and on the right side you will see the main board.On the top portion of the board you will see a white ribbon cable. Unplug it and look at the silver contacts on the very end of that cable. Then reseat that cable. That may be the problem. More than likely though you have either a dirty mirror in the scanner. Which would require removing and cleaning the scanner thoroughly.
The laser may also need cleaning. The toner cartridges for that machine leave a lot to be desired also. When you get a bad copy remove the toner, shake it from side to side and see if that fixes the problem temporarily. The blades that put the proper amount of ink on the toner roll fail often.
The scanner failing would be my first thought.
Also go to Xerox.com, select support and drivers, then enter C20 in the search box. Then go to drivers and downloads and install the newest firmware for the machine. You may have a machine software issue.
I have worked on that machine since day one of its existence, I never did care for it. It is a cheap machine made by Sharp corporation for Xerox. It really isn't a Xerox product, they just stuck their sticker on it.

XEROX CopyCentre C20-Blank stripe going down side


Open the cover and put a piece of paper on only half the glass, and make a copy. BLOCK the left side of the glass with the blank paper.
See where it is blank. Most of the times that is a dirty or haved up mirror in the scan head. One of the small mirrors in the black assembly under the lamp. When a digital copier scanner optics become dirty, the image in that area becomes very light .

Xerox copycentre c20 paper jam in 2 how do i get it out please


Unplug the machine, open the right door. Get a phillips screwdriver.
Look on the upper portion of the paper path, you will see an assembly with yellow waning stickers that say HOT. There are 4 silver screws on that fuser assembly. Remove those screws, and unplug the white connector. Pull back toward yourself to remove the fuser.
Lay it down and remove 2 silver phillips screws , it will open up and you can remove the paper. Make sure the machine has been off for a half an hour or so, It is hot. Take a good look at the black aluminum coated roller on top. See if it looks smooth and clean, If it has a lot of toner built up on it, you will have to repalce the fuser or it will continue to jam and give you ghost ( light reprinted) images up and down your page.
Also the M20 does not handle large black ares on a page such as a picture or magasing cover being copied. Largs solid areas tend to stick to that heat roller. If you do copy a photo, try and allow about 2 inches on the top of white. Just move your original down on the glass about 2 inches from the edge. 2 inches to tie right of the edge of the glass.

Xerox Copycentre C20 Prints nothing but blank pages


Is the paper (copy) truly blank? Please look very close at the page. It sounds like the coratron (charge) wire (s) are broken. These are thin wires this use electrical charges to transfer the image onto the paper. You can go online and order a small spool of the wire and restring the wire. You do not have to be a doctor to do this repair but a steady pair of hands is very good. NOTE:::::: pay attention, most of the coratron units use tiny springs... so look and listen in case it falls out. You can restring with out the spring but it is better with the spring. Remember when stringing the wire, not loose but do not over tighten.
