White band running thru copy

This machine is about a year old and i replaced the toner not very long ago and have hardly used it.
on every copy i make there is a white band running vertically thru the copy. You can still read the text, but it is lighter than the rest of the copy and there is a distinctive band that goes thru the middle that is white.

I have a mfc-8440, 5 years old, low usage, 50% drum life, new toner cartridge. The problem is that the contrast of the printed copy does not change regardless of the setting using the path...


This is very easy to solve. Remove the drum and toner cartridge. Look into the machine where they sat. Now look up and you will see (a little aukward but its there) a glass plate the width of an A4 sheet of paper. Run your finger accross it. Look at your finger and will probably be dirty. This is the window the laser beam passes thru to hit the drum. When its dirty it does not allow enough ;light to the drum hence a weak beam and light printing.
simples?

I recently changed my copiers toner (the change toner light came on) and now my copies are uneven (alternating in light and dark patterns). I properly shook the toner, I even returned the toner to get a...


The light and dark banding going horizontally accross the page is usually caused by the drum unit. This is the smaller of the 2 cartridges and it sits just to the right of where the toner sits. If you have a spare drum unit, replace it. This should resolve the problem. The Toner cartridge can also caus this but if you have tried 2 DIFFERENT units with the same banding then it must not be the toner.
Good Luck and Thank You for using Fixya.

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 XC1020 White Bands running across copied page 4" apart


The metering blades in those cartridges go bad and do not allow the ink to get to the page. Look at the front of the toner cartridge, is should be a solid consistent black all the way across, if its streaky, not consistent all the way across replace the toner.
The other problem could be a dirty laser. If replacing the toner doesnt work let me know, I will tell you how to remove and clean the laser.

Hello mine is really an FT3713


This sounds very scary...
Your Machine is very old..
What did you do last to the Copier to get it in this condition?


All you should have done is empty the Waste Toner bottle, and do SP83.

Hello Bob,
Where are you located? You should be able to find the toner for this machine. Have you tried www.precisionroller.com ?
I am almost positive that they carry the toner and also consumable part as well as replacement parts.
One of the reasons the copies might be dirty, is that the optics, charge wires, cleaning blade, drum, and or fuser unit might need some parts replaced. Without seeing a copy of what the machine is actually doing, or looking at the machine, it's hard to pin point exactly what is going on.
If you have any questions with the machine, feel free to post any questions and I will be glad to help you.
Good luck.
Hope this helps.
Mac =)

Canon PC940 Problem


You could have a broken exposure lamp. Does the scan bar light up when you make a copy? If not that is the problem. You might also ck the contacts on the machine where they touch the toner cartridge. The toner cartridge opens a shutter to the drum when you slid it into the machine and that may be broken.

Al-1631 Sharp copier


You could have one of several problems. Seeing as how you just replaced the toner, it could be a defective toner. Did you have the trouble prior to cartridge replacement? Did you replace it with OEM or after-market/refurbed stuff? You could also have a broken corotron wire. On the right side door is an assembly that has a very fine tungsten wire strung across it. This wire places a charge on the paper to "pull" the image off the drum. if it's broken, you will get blank (or almost blank) images). A 3rd possibility I have seen is that your scanner lock is on. Usually this will cause L1 codes, but I have seen cases where it didn't, and your scanner never moves from "home" position to scan your originals, again, resulting in no image being processed, and therefore blank copies. The scanner lock is under the scanner assembly (above the area where your copies come out) on the left side of the machine. It is a dial mechanism that can be turned to either the locked or unlocked position. It's hard to see, and you almost have to stand on your head to get a good view of it. It is not uncommon that in the process of removing copies from the "catch tray" area to accidentally brush it with one's hand, or watch, or ring, and spin it to the locked position. Certainly a bad drum can effect copy quality as well, but before spending the money, I'd check/re-check the other 3 first.
