Vertical lines Each fax/copy has two clear vertical lines down the page which makes reading the message difficult, whats going on here.

SOME all in one printer SCANNERS like Brother and others can HAVE AN AUTOMATIC PAPER INTAKE on top of te device ( copy device )and if on the left side of the glass plate under the copy unit is a narrow glass strip to find that needs to be cleaned if there is a little spot of dirth on it then it will give a stripe on the same part after every copying session on all papers a small point can be very difficult to see, but if the small glass stripe is cleaned the problem is solved.

Problem Vertical lines; Auto document feeder scan anomaly; ADF scanning problem; Scan issue; Scanner issue; Visible line; Streaks show on page; solid line down the page; Top to bottom line; Smudge runs down the page; Opaque line; Broken line; Bar all the way down the page Solution Overview

This article provides the self-diagnostic steps necessary to evaluate top-to-bottom streaks that appear when copying or scanning.

Important! This is seldom a scanner hardware failure.

The main reason for this anomaly is debris or marks on the scanner glass that is used for Auto document feeder (ADF) page scans.

Printed or Scanned Page Illustration

Who should consider this article?

Any user of an MFP or All-In-One printer experiencing the following symptoms:

• -Vertical lines only when using the Autodocument Feeder (ADF).
• -Observed with any type of scan job (e-mail, ftp, solutions, fax).
• -However, normal expected output when the page is scanned from the scanner flatbed.

ADF scan behavior

Think of it this way:

• -The page is pulled from the ADF.
• -The moving page slides across an ADF-designated portion of glass.
• -The image sensor, which is located under the glass, reads and interprets the moving page's contents.
• -Contamination on this ADF glass is seen by the image sensor for the entire length of the page.
• -The image processor interprets the image sensor's repeated capture of this contamination as a vertical solid line.
• -Any ADF scan function now exhibits a vertical line.

Suggested Diagnosis and Fix

Step Action 1 Locate the portion of the glass designated for ADF scans.
HINT: The glass location differs by model. This area is often separate from the scanner flatbed. Please reference User's Guide for more information if you are having a difficult time locating this designated area.
2 Perform a visual inspection for any of the following recurring culprits:

• -Clear adhesive tape
• -Glue
• -Ink pen
• -Paper
• -Marker
• -White out
• -Staples
• -Environmental dust or dirt

HINT: Ink marks can be especially hard to see and almost translucent at first sight. However, the image sensor (CCD) registers them as a mark. 3 Use a clean, soft, moistened cloth to thoroughly clean and remove any marks or debris. 4 Inspect the underbelly or underside of the ADF for any marks or debris. 5 Perform another scan to see if cleaning the glass alleviated the issue. 6 Repeat the procedure if a vertical line still appears.
Remember! Printing and scanning from the scanner flatbed work fine.
7 This time, place an intentional mark on a blank sheet of paper and take note of its location. Now place that sheet of paper in the ADF and make a copy.
8 Evaluate the distance of the vertical line to the your mark. 9 Inspect that area of the glass for further debris or marks and clean as necessary.

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. 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.

there is probably a dirt spot on the scanner glass where the document feeds in. try cleaning the thin glass under the document feed cover.

This can be caused by a damaged fuser or drum try to change the cartridge and if that does not resolved the issue then its the fuser

You have to clean the scanner.Open the dock feeder area,and make sure the scanner glass is clean sometimes the glass look clean but just a smaal dot on the glass can cause a line.Clean also the white area above the scanner.The white area above the scanner help for shading operation of the mchine.Make sure you clean with a sullotion that can remove ink but not damage plastic.

does it do it on copies and internal test as well???
1- check the thin strip of glass inside the machine and make sure it is clean, look at the toner are there any line on there that corresponds?? yes then replace.it could be coming from the drum or toner. I beleive the drum is a seperate piece from the toner

TYPICALLY SF900 FAX USES A DIFFERENT CIS SCANNER , THSI SORT OF INDICATION IS EITHER SMPS BAD OR CIS SCANNER BAD. HAPPY FAXING OMNIRESENT

Make sure you have good OEM supplies installed. Use a good vacuum and clean the toner from the laser scanner window.
