Was there any resolution to this problem?

SOURCE: Persistant error: "Document remains in scanner. Open door and remove document."

I get calls about this all the time. The most common reason for this is the shiny reflector for the Ending Sensor is dirty. It is best to clean this with a cotton swab and a few drops of rubbing alcohol.
Although it is possible that one of the sensors has gone bad. The Panasonic User utility is very basic, but if you have access to the Service Utility it will help pin-point which sensor is causing the problem.
Out of all the calls I've taken relating to this same issue, only two or three situations have been resolved by replacing the sensor - all the rest have just been dirty.

SOURCE: lines in scanned documents

Usually cleaning the glass over the LEDS will take care of any lines. I reccomend you try this first.

If the scanners keeps blinking while powering on, it is because it has not been intialised. Check for loose shreds of paper in the paper path. Unless the scanner intialises, it cannot scan. If simpel 'countonly' option works, then the scanner is okay.

I havent used Canon 2580C and hence cant comment on Scan Panel. But you can download SU5000 or Captureperfect 2.0 from Canon website ( This is easy to use and probably offers more features as compared to ScanPanel. Canon 5010C is a higher model as compared to 2589C and Captureperfect may offer better user interface.

Canon DR-9080C Scanner all of a sudden all color documents scanned have a pink tint to them. I do not know how to get rid of the pink. Have been using the scanner for years. Also use Adobe as the...

Sounds like the shading compensation strips may be dirty and/or sticking. Otherwise the scan sensor is going out.
To check and clean the the shading compensation strips:

Open the feeder up all the way and hold down the red stop button. about 5 seconds the upper and lower shading compensation strips will pop up.

They may be getting stuck and not popping out all the way (about 1/2")
Clean them up with a small brush and a lint free rag with alcohol.

If the shading sensor strips aren't popping out all the way, this will cause the problem you described, so clean them up and repeat this several times.
(They pop up during the document scanning process)
If they still aren't popping out after cleaning them up, then there may be a mechanical problem with the mechanism.

Hope this helps! You may need a tech.

I've cleaned the glass and still have a black line on the image

Scan a document in 300 dpi in full width. Check where the line appears in the image. For example if the black line appears at vertical position say 1900, then it means the dirt is at 1900/300 i.e., 6.3 inches from left. Clean the area thoroughly. Check if any pin had created a scratch in the glass. At different contrast levels, if the line appears different, it is definitely unclean glass. On the contrary, if the line appears constant at various levels of contrast, then it is possible that scan module is faulty.

I clean the glass but there are still black streaks

Try scanning the same document in two diff brightness levels (in B&W, say one at 75 and other at say 210. I am assuming you are using CapturePerfect. If the black streaks are same in both the images, then it could be scan module problem. If the streaks vary in size, then it is definitely dirt on the glass. use isopropyl alcohol (rubbing alcohol) to clean the glass. DONT USE solvents. S. Mohan, Chennai, India

When scanning, there are lines on the image I have scanned.

Use a blank sheet of paper (as white and clean as possible). Put it in the scanner landscape ( you will need to cut off about 1/2 inch of the paper to make it fit. The run the DR-3080CII Shading tool (DR3KUserSh.exe) C:\Program Files (x86)\Canon Electronics\DR-3080CII\DR3KUserSh.exe

Canon dr-7580 scanner how to initialize cis

If the Black lines are jaggered and are vary in size with different levels of brightness, then most likely it is scratch on the glass. If the lines are sharp and perfect and does not change when different brightness is chosen, then it could be failure of CIS module (Try this under B&W mode). To the best of my knowledge there is no concept of initialising the CIS, you may need to clean the Shading sheet.

Scanned images are scaled

the feed rollers likely have paper dust accumulation and are slipping .. you can clean them with special cleaning fluid or just water .. dont use alcohol since that can remove elastomers that give it traction ... since you have so many pages thru the machine then the rollers may be warn or hardened and need replacment ..

Image problems

The lower scanner unit moves when doing the shading adjustment (scans the little white plate on the top and bottem scanners). Most common problem is a staple interfering with the lower scanner movement.
