Try doing an internal printout. press function-6-4-start- and if there are lines on that paper that prints out. you need to replace the drum on the machine.

The CIS scanner has one of the LCD bits bad. If it is new, claim a warranty repair. Otherwise, strip the scanner out and go over all the solder joints

As the fax receives and prints incoming faxes ok then the print engine is working ok. the fact that the problem arises when copying or scanning indicates the problem is with the scanner or software that controls the scanner.
First clean both scanner glasses and the white area (white reference) under the doc feeder. When you are happy all is clean, follow the following instructions:
Press menu, * 2864 within 3 seconds. the display will show "Maintenance"
now press 55. The scanner will initialise and go back to "Maintenance"
now press 99 and the machine will go back to the default screen showing date and time.
Now do a copy. if you still have the lines or its all black then you will need a new contact image sensor. If all is well then that was a good cheap repair.

The faxed copy has a big black line in the middle of the paper. A new toner and a new drum have been installed but the line is still there. Help! Ruth


Clean the scanner glass. This is the smaller piece of glass that is located just to the left of the large original glass. Or if you have an older or smaller model Brother the strip of glass is going to be located under/inside of the port where your documents are fed into the machine. This operation panel usualy just pops open and you can find the strip of glass inside. Just clean it with a bit of glass cleaner that has been sprayed on a soft cloth. Make a copy with the machine to test if the line is gone. If the copy mode comes out ok then your outgoing faxes will be ok. You can also make a copy before you start the cleaning process as the copy with the line on it can aid you in determining what area the glass needs to be cleaned.
Good Luck and Thank You for using Fixya.

When making a copy on our Canon copier (super G3; image class MF4150) we are getting a vertical black line down the entire length of the paper. Is there something we can do to fix it? SG


You can fix this yourself by cleaning the scanner glass. When you insert a document to make a copy it is pulled in and travels over a thin strip of glass. When something gets stuck on this glass it is read or scanned as a solid line. What you need to do is make a copy. Then put that copy in the feeder the same way you put the original document in. Now the line on the copy will "line up" with the area of the glass that has something stuck to it. Use this as a guide to pop open the feeder cover, locate the glass and clean it with a cloth dampened with a bit of glass cleaner. Once you have it cleaned just run a copy again and the line should be gone. Sometimes a small flashlight helps to locate the glass.
Good Luck and Thank You for using Fixya.

BLACK LINES WHEN TRANSMITTING ON THE PANAFAX UF 895 AND WHEN PRINTING A COPY BUT NOT WHEN RECEIVEING A FAX NOT THE TONER CARTRIDGE


If the lines are thin, open the document feeder by pulling up on it and clean the small glass.

If they are 1/8 inch or wider, some elements are burned out in the LED scanner assembly.

Getting a black strip in copy mode on X6575 lexmark printer. No line in print or test mode


Most likely a page was scanned with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page.

If this is your problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.

I have a black line showing up on my faxed documents. I have opened it up, changed the film and re- set it, but the problem persists. The machine is about 5 years old.

Black lines on faxes


Open up the document feeder (where you put paper to send) and look for wite-out on the thin glass.

If it's not dirty, you probably have a bad scanner unit. Uneconomical to repair.

POOR COPY QUALITY


Here is the scoop! There are two (2) components to the fax machine, one is the scanner portion which is located just past where the paper you are copying or faxing enters the machine, separate the two sides and access the imaging plate, clean this area with denatured alcohol.
Step two is to clean the toner and drum unit, get the mirror at the back of the toner and under the toner. If after this you are still getting lines on the prints you will have to replace the drum unit KX FA-84 about $85. Happy faxing, Ken
