Question about Canon CanoScan 8400F Flatbed Scanner

Yellow streak through color image scan

When I scan color, it doesn't matter where I position the item to scan, I get a yellow streak through the scan. The streak is so bad that I can even adjust or tone it out of my photo. The scanner is an Epson Perfection 3490 Photo scanner, only 2 years old. It used to work great. Can you tell me what is wrong and how to approach fixing it? Thanks so much.

Crysti Esper I've been using the CanoScan 8400F for a few years with no problems.  Suddenly I started getting a yellow streak down the right side of the page on all color scans.  It seems to be getting larger.  I've emailed Cannon, but so far to no avail When scanning a color picture the image has a yellow streak covering about 25 % of the image. This problem did not occur when the scanner was new

There might be many causes of lines on the image.. Depending on weather the line is Horizontal (Parallel to the scan lamp) or Vertical (In the direction of the motion of the lamp).
Vertical lines are due to certain CCD cells not responding properly, and that "bad spot" is moved down the page by the carriage motor, making streaks. The problem can be due to dust inside the scanner, on the CCD or mirrors, blocking light from reaching the CCD, and these tend to be dark lines (perhaps dark in only one of the RGB channels) and relatively few in number. The problem can be defective electronics in the scanner, and these lines often appear as red, green or blue lines (stuck on), and sometimes in great numbers or width. However, a deposited film on the mirrors can be wide and colorful too. Vertical lines tend to always be at the same place on the width of the scanner bed, being caused by specific CCD cells
Horizontal lines are an event in time. Rainbow colored lines might be due to a flickering lamp Or the scanner has an internal high frequency power supply for the lamp which might cause such a problem. A faulty or incorrect or insufficient power cube may be the problem. Is the problem everywhere, or random locations, or always in one place in the carriage travel? It could be irregular movement of the carriage due to loose belts or sticky guide rods or other mechanical interference can cause "glitches". You might notice the lamp flickering, or watching the carriage carefully while it moves might show some type of binding. Horizontal lines due to lamp problems are random, showing at whatever location of the carriage at that point in time, but a sticky carriage would probably always be seen at the same location. Effects of an insufficient power cube is probably seen all over the image.

Hope this would help you to pin point what might be the problem.
Let me know if that helps and rate the solution if you liked it.

Thanks and Regards,
Srinivas

Light yellow streak down the center


there is a prism in between 3 lcd panels that the light shines through for the image. each lcd panel has a color filter between it and the prism. after a while the filter will fry, creating the discolor on the image. unfortunately, you cannot but just the filter. you'll have to get the entire lcd/prism assembly. it's pretty tough to get it out, so you might want to bring it someplace that can do it.

Red and yellow streaks appear in scans, always in the same location. The scanner was cleaned but the repair person could not find any problem with the equipment. Yet the streaks persist. How do I resolve...


execute a calibration to correct the wrong color:
  1. place your photo on the scanner, with a distance of 0.25 inch from the edge of the glass
  2. open Epson scan and select Professionnal Mode
  3. select the document source
  4. select the image type
  5. uncheck thumbnail then click Prevew
  6. crop the area of the image
  7. Click zoom to fine tune the area you see the streaks
  8. select the resolution of 72 dpi
  9. scan your photo

if the problem still not solved, you need to change the scanner unit , there are many dead pixels.

Yellow not printing - but only in streaks


Your yellow problem sounds like a bad yellow developer housing. Take the drum out and look at the developer housing, You will need a flash light to do so. See if the roller is solid yellow. Even if it is there may not be any developer left in the housing.
The Cyan sounds like the drum since it gets worse as it prints.
That can also be caused by the transfer belt cleaner. But that normally is the opposite. It has a rainbow sort of streak and it gets better as the machine runs.

Yellow Streak on Images


I took the scanner apart. Then using a dampened eyeglass cleaning cloth, I gently cleaned the 3 internal mirrors.
No more yellow streak! :)
