Canon 9080C not scanning 11x17 pages

You probably need to set the user settings to "long doc" mode.

1) When the machine is in the standby state,
press the NEW FILE key and Count Only key
simultaneously. During the user mode, the
LEDs of the NEW FILE key and Count Only
key illuminate and the address (U01-U10)
and data (the last digit) appear on the
counter display.
2) When changing the address, use the NEW
FILE key. Each time NEW FILE is pressed,
the address changes, cycling from U01 to
U10.
3) When changing the data, use the Count Only
key. Each time Count Only is pressed, the
data changes.
4) Pressing the Stop key exits the user mode.

Long document mode =U10; 0=normal and 1=long document mode.

Happy Scanning!

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.

Duplex scanning, Color Scanning and high-density scanning (600 dpi) cannot go with long documents like 11x17. Change the scanning mode, try one side at a time or reduce the resolution.

Hi
what size page are you trying to scan, if they are smaller than the gap between the transport rollers, they will not feed.

the single sheet problem you have:- the scanner knows when there is paper to feed when the sensor is pushed up beside the pick roller and it will put the tray down again when the rollers are pushed up. sometimes the little plastic sensor to the left of the roller gets a bit stuck and needs to be freed, it wares itself out where it hinges inside the cover around the pick roller. just unclipping it and cleaning it is usually enough.

good luck.

Sounds like you need a new CIS unit, the scan assembly or its lamps are flickering.

You are right, it is driver related issue. Acobat 9 has more features that may not be compatible with the existing driver. may be you can use CapturePerfect and directly create PDF and then use the Optimising features of Acrobat 9. Ofcourse you have to do it twice, but you can use the 'batch' process and do it automatically.

There is a paper sensor just under the rolers in the lifting tray. Clean the area thoroughly with a damp cloth. Keep some sheets and try ]count only'. If it works then the sensor is okay, then you can try your scanning. If it is not sensing paper, check the sensor or connections to the sensor.

U should select 'Scanners maximum'  and try this. I have found this does not work midway, after some scans. So close and exit out of captureperfect, re-enter and try. This should work.

I have two of these scanners the only way that i have found round this is to scan the pages duplex then remove the unwanted afterwards!

Do you have enough disk space? Check if your C; drive has enough space. Normally C: is used as 'scratch area'. Try scanning intoa different location.
