Dirty scan glass

Clean slit of glass extremly well, it is a small slit rectangler section of glass before copy glass on the scanner.

Glue, Liquid paper are common finds on the glass in this area, While you have the lid up, clean white reference area (on lid directly on top of scan glass when lid is closed)

Check your flat bed and Document feeder scanning glass need to be clean, if any dot or dust in scanning glass of document feeder it will appear a line, check this points first
1- Check printouts from computer or FAX if it is clean problem in scanning section
2- Check using Copying a blank paper using only Flatbed if it prints without any line its problem from document feeder Scanning glass
So solution is clean the Document feeder scanning glass using wet cloth, note careful about wet cloth switch off the machine and clean it

Black lines when sending faxes or making copies


I've been getting many calls asking me why their fax/copiers/printers are getting black lines when they send faxes and making copies while using the automatic document feeder, and not when they open the document feeder and use the glass.

What happens, when you fax or copy papers that has white-out or some material that can flake off, it gets embedded on the ADF glass and the unit thinks its part of the paper.

99% of the time, what needs to be done is to clean the small glass, usually using fingernails to scratch off the dirt, or using a lint free cloth slightly moistened, should do the trick. Just go over it several times until it comes off.

If the lines are thick, it usually indicates a damaged scanner assembly, in cases with the Brother machines, not expensive to fix. With other units, its a different story, either because they do not sell the scanner assembly as a part, or units are sent in for whole unit repairs.

Copies leaves lines when put through the feeder,but not on the glass .......have cleaned and sprayed air can everywhere I can think of The Hp Printer is HP 3055 All in One printer


Most likely a fax has been sent or a page copied 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, scanning or sending a fax, 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.

Faxes sent are being received with lines on the pages


You need to clean the glass real well, the narrow one if you fax from feeder and the big glass if you fax from flatbed. After cleaning you power off and on so it will calibrate to clean glass. Test by making a copy, the copy will look just like a sent fax will look. If you still have streaks you may need a new CIS scanner, around $60.00

Every Fax we send has stripes going down it making it hard for the receiver to read our faxes. It doesn't happen when we receive fax, print or make copies.


You say it makes copies without the stripes. Do you use the automatic document feeder (ADF) when you make copies, or open the top and lay the paper on the platen? If you get stripes when using the ADF, the ADF scanner area needs to be cleaned. It's the smaller glass area to the left of the main platen glass. Use a damp cloth and remove any dirt or debris.

Black lines in copies and fax's Brother MFC 7420


If the black lines comes when using the ADF (top feeder), try to see if you get the same problem when using the scanner glass or receiving faxes. If you don't, you simply have to clean the glass strip to the left of the a4 sized scanner glass. Wipe it with a dry cloth piece, no paper and no water/alcohol. If you see some dirt there that you're unable to simply wipe off, try to use a cotton wool to "rub" it off.

Two lines, one on each side of copies made from feeder and faxes


Try cleaning the rollers inside the scanner including the glass inside and out with a soft damped cloth. Look also for a piece of paper, staple wires, paper clips or pencil lead jammed inside the rollers or somewhere in the corner.
Also, look for a foreign object or substance on the cold cathode tube light and clean it. Try also cleaning the mirror.

Black line on my fax copies!


You sure can - the issue is that there is something on the thin strip of glass where the copy goes through from the feeder at the top - follow these directions and you should clear the problem right up.
