IMAGE SENSOR defectives. replace it.

See this link regarding the strange colors and horizontal lines on your LCD. A bad image sensor (CCD) can cause the issues you describe.

This sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following two links for more info:

I suspect your camera has a defective CCD which is quite common for the A75.   Canon is aware of the problem and has issued a recall for affected cameras.  I have had mine repaired under this recall.  Here is a link with some pictures which show what the problem looks like.

I hope this helps

If you are using original cartridges then there should not be a problem. The horizontal lines come from the cartridge. Can you pinpoint if it is a color or black line that is missing? My guess is that during the alignment procedure, you are asked to choose a number or letter that corresponds to picture of a the lines that show the best alignment. If you did this correctly, may I ask how many pictures you printed before seeing that line. Is it on the first print or 10th printing? Cuz if it is on the 5th or more full color picture, then the problem is that you you really have the wrong printer. The F380 capacity for printing full color pictures is miniscule. 1 ml per color. So usually after the 3rd color picture, the ink starts to run out. Let me know if this helps.

What is the make and model number of your set? I may b able to help you. desribe in more detail is the picture gone entirely and you only see colored horizontal lines on ablack screen?

According to many respected sources with far more expertise than myself, the symptoms you are describing also fall within the realm of Canon CCD failure. In Canon's Service Notice: CCD Image Sensor Advisory, they outline the most common symptoms (distorted images, LCD showing only a black screen, etc.). They have conveniently limited the description to the bare minimum. More symptoms of the failing CCD include: pictures appearing on LCD show up with severe color variations (pink-purplish or green tint), colored "streaks" or "lines" throughout pictures, and wavy distortions in image. Most of these symptoms include the color variations, but not always. The lines or waves can appear in any direction and with varying degrees of severity. Some LCDs do not go black, but turn totally purple. Here is a link to a very informative article that should clear up any questions you might have.

If nothing else, call the Canon Customer Support Center at 1-800-828-4040. They will ask questions to identify whether or not you are having the same symptoms as described in the Product Advisory. I have been through this twice, and both times they were very nice and very helpful. Even if you don't qualify for the free repair, it didn't cost a thing to find out.
I hope this has been helpful.

Sounds like a bad imaging drum to me...

Depends on whether the "lines" are colored or just blank areas missing in the print . If it is blank areas , then most likely the laser scanner is dirty and the glass needs to be cleaned . If it is colored lines , then you most likely have a defective drum .
