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)

We received a cople of faxes from different sources. There are lines down all the pages except the top (there is readable text there) and the lines are from the letters (like they have been stretched) like...


That sounds exactly like the sending fax is document is stalling, so a single line across the page gets sent for a few seconds. You can easily check your own machine's scan and print quality by putting anything in the doc feeder and copying it.
To test the print section alone, use the menus (or I think your model has a separate Report button) to print out the Help list.
It's possible that both your sending correspondents have slick, hard document feeder rollers, but you'd think they would have heard complaints from others. I can't think of anything at your end that would stretch out your prints, and there's no Bulletin about it on Brother's service website.
On the off chance you have a glitch in your machine's memory fouling it up, you can clear it out. This page has instructions for clearing out only the image memory (91) or all of it (01). It may or may not help, but only takes a couple of minutes to try.

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.

Unwanted verticle line on fax copies


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 the cause you will also find that faxes you send to other people will also have this line (although faxes you receive are not affected by this problem with your machine).

To fix the 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 get lines and can't read the right side of copies that I make with the 1270e. How do I fix this?


You have not specified why you can't read the right side of copies and I am assuming that the reason is because the 'lines' are covering the text. I can offer a solution to the lines issue.

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.

I have a Ricoh 2050L that is leaving vertical lines on copies by not transmitted faxes. How do I clean my fax or who can perform the needed service. What is a fair price in the market?


What you are saying cannot happen. When you send a fax or make a copy, you are using the same mechanism. Do you mean print outs instead of copies?

Open the doc feeder and clean the scanner glass.

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.

Document sent is blank for recipient


Hi there check the machine scanner light by putting the original in the feeder and doing a copy. If the printout comes out OK then it either could be the other fax machine you are trying to send it to or you have a intermittent fault with your scanning lamp (Section).

You also must make sure that the original is text face down.

Hope this helps you
Thanks J
