Question about Canon DR-2580C Path-Through Scanner

1 Answer

Image problems About four inches on the left sides of documents just come out white. I cleaned the glass, the rollers, everything and it seemed to make it worse. I've had it for about a year and a half and it was working fine. I reinstalled the drivers, everything.

Re: 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.

Bizhub C652 has horizontal lines.

its important to find out whether the \'lines\' are in scan direction/ or only through Radf or only from scan glass,

if the lines are only showing when documents are fed throught the Radf, then the problem lies with the document scan plate( left of the main glass platen (about 2" in width)) or with the scan plate blade cleaner

if the lines ONLY appear when copying from the Glass then the issue lies within the optics (probably nothing more than a clean will be needed)

another question would be to ask if the lines are solid (black line overprinting image) or if they are \'missing\' lines where the image has failed to copy, sometimes it can be hard to work out which side the fault lies,so try shaded greys as a copy original .

if the scan lines are appearing on both Radf and Glassplatten ,mode then the issue may be dirty optics/ccd sensor or it could e an indication of the ccd failing or image control pwb in error while interpreting the image file.

what to do

1) place a grey sheet of paper in the Radf and have the copier photocopy both sides of the original and print to single sided sheets ( so the printer turns the original over to complete the task)

observe the result.

2) have the copier photocopy directly from the platten glass- single sided.

observe the result.

ckeck to see if the error has appeared on both sets of prints ,

if the error has only appeared in the first set of prints then the issue may be a tiny DOT on the slit glass (left of platten) - a dot on this glass will indeed appear as a Line as the original is scanned across the glass.

When I scan a document in the canon 9080c scanner - the document when printed will print with a black line through the middle of the page or on the left side of the document. I have changed the rollers and...

Try scanning a few documents in full size mode (scannerrs maximum), If you observe a line in the same location in all images, you can conclude that there is either a scratch in the glass (due to stapler pins) or dirt stuck firmly. Try cleaning with Isopropyl alcohol. For absolute emergency, you can wet a cotton bud in after shave and clean the right spot, take care not to touch any other part other than the glass. If glass is scratched, you need to replace it.

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.

We have a Canon DR-9080C scanner. When scanning in Duplex on pages with data on both sides, the back side of each page is coming out unreadably faint. The header and any overall large blocks of black on...

The Canon DR 9080C is a 'contact' scanner. There is no optical lens, instead it uses a technology called "Contact Image Sensor' or CIS. The page to be scanned must be close to the glass for a proper image. This is achieved by a full-length rubber roller just above/below the scanning module. The roller is spring loaded and in case it gets stuck, there wont be enough pressure on the document to keep it close to the glass. ensure these rollers are moving smoothly and if required clean them. The rollers are on the opposite of the Scanning module.

Look at the glass strip through which the documents are scanned. Even a tiny spot there results in a dark line along the scanned image. Often such spots come from scanning a document with corrections made using the white correction fluid :)
The users manual (UM) describes the cleaning procedure on pages 61-62, you can get the manual here:

Black line through the middle of the document

The thick line is either because of dust sticking to the glass or a module problem. Try different brightness settings and scan white paper. If the thickness varies and also the sides of the black strip are jaggered (step like) then it is dust on Glass. use isopropyl alcohol to clean, dont use solvents. If the teickness is same for all levels of brightness and has a sharp edge always, it could be scan module problem.

Scanned image on left is cropped by a good quarter of an inch.

To get the image on the right side, Select 11" wide and the length you want. Keep the paper guides at the far ends. Insert the paper at the extreme right side and the image will appear on the right side. The left side would appear dark and You may need software to clean. If you dont have Raster Editing software, best way is to stick your image onto a white paper and scan the whole paper. Ensure that the ends are trim. ( I am assuming it is faceup scanning)
