Red vertical lines, scanning to computer

THE BLACK SCANNED LINE IS PROBLEM OF THE SCANNER CARRIAGE AND HAVE TO BE CHANGE.

Probably there is nothing wrong with that scanner, just open and clean document feder with alcohol or glass cleaner.

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

Unknown if this is new installation, or old installation that went bad.
Old install, then check voltage is correct for rating plate, check that line power is not under-voltage, check that photo control receives enough light by shining 120Volt light bulb onto photo eye, replace photo eye
New install, check wiring. Photo cell has 3 wires, For example Black White and Red.
Black and White connect to power source, and Red goes to load.

Documents scanned/copied from the document feeder pass over a thin glass area where scanning occurs. Clean this area if sent faxes, copies or scans have black or white vertical lines.

1. Lift the document cover to expose the platen glass.
   
   
2. Wipe the ADF scan area (C) with a clean, soft, lint-free cloth moistened with water.
   
   
   
   
3. Then wipe with a clean, soft, dry, lint-free cloth making sure there are no residues left, especially on the platen glass.
   
   
4. Close the document cover and make a copy of a text document to confirm the black line has disappeared.

See previous fix for black lines problem is likely the same i.e fractures in the flexible cable between the scanning head and mother board, changing this cable will likely cure this fault.

For this kind of problem you need to call the tech support because the printer is already messed up and it is in need of replacement

Hope this help

A long black line on scanned images is usually caused by a piece of trash on the scanning mechanism.
Look at the scanning arm (the thing that moves when you scan something) and then see if it has any trash on it. If it looks good then you may have a mechanical malfunction in that part.
Let us know hat you find.

well as i know there is a selection when u r scanning asking u to scan either in black & white or color

did u check that? maybe its switched to the black and white option
