Can you auto-aline with CapturePerfect 3.1 version 3.1.12

Normally it is advisable to use only one Scanning Software. The software has various files which may overwrite the previously installed version. The later version works good.

It is also possible that the brightness/contrast settings in Captureperfect 3 is not proper. Try scanning after altering these.

Wht must be done is to first uninstall the drivers from your PC and then install once again the software with the PRINTER DETACHED. Connect ONLY when the PROMPT appears and then rrun an alinment of the paper- you need to take a test print and place it on the scan table to make the printer alignment correct.
Please read through the manual to confirm- which can be downloaded from the Hp/support site.

IF you are using CapturePerfect 3. version, you can select "Auto detection" for page size, and under 'more' select 'image size' instead of guide plate. Also you may have to select option '1' under user code U10 in case you want to scan pages over 17 inches long. (Press Newfile and Countonly simultaneously, press 'newfile' till you get U10, press 'countonly' and select 1. This will enable scanning upto 1 meter long).
CP3 has "Skip Blank page option", this helps you to automatically delete blank pages on the back side and scan only those with data.

Open the Applications folder on the hard disk on which MP Navigator is installed, then open the Canon Utilities folder and double-click the MP Navigator 3.0 icon. MP Navigator opens.
2. Point to Scan/Import and click 'Photos/Documents (Platen)'.

3. Place the document face-down on the platen glass, and select 'Document Type'.
How to place the document and Document Type depends on the document to be scanned.

How to place the document
Allow 3/8 inches (1 cm) or more space between the edges of the platen glass and the document.
Align a corner of the document with the corner at the arrow of the platen.

• When you select Color Photo or Black and White Photo, the position or size of the image may not be scanned correctly if you do not leave 3/8 inches (1 cm) or more space between the edges of the platen glass and the document.
  
• When you select Color Photo or Black and White Photo, the position or size of the image may not be scanned correctly depending on the document. In such a case, select Document Size such as A4 or Letter according to the document to be scanned.
  
• When you select Magazine(Color), the Descreen function will be enabled and scanning takes longer than usual. To reset the Descreen function, disable Descreen in the Scan Settings dialog box.

4. Click 'Specify'... and set the preferences as required.
The Scan Settings Dialog Box opens. Specify the Document Size and Scanning Resolution.

• When Document Size is Auto Detect or Auto Detect(Multiple Documents), the position or size of the image may not be scanned correctly depending on the document. In such a case, select Document Size, such as A4 or Letter according to the document to be scanned.

5. Click 'Scan'.
Scanning will begin.
When the document has been scanned, the scanned image is displayed in the Thumbnail List area.

If you are using CapturePerfect 3, select page size as Auto-detection, detect size by Image width, Deskew by roller & Image, then you will get images exactly as that of the scanned image.
If you ae using CP2, then you can select Auto-detection AND page detection. The problem with CP2 is if the image is less than that of the guide-plate, you will get black background. You can clean this through software.
If you had select B&W scanning and chosen to save file in JPG format, the scanner will report error. JPG is only for Color/ Grey scale.
With CP2, I have observed that sometimes, the changes are not retained, unless you select 'default' first and alter the parameters. This is not found in CP3.

A 'Driver' is only the software portion to connect two hardwares. You need to install a printer driver for Printer, or a DVD driver for a DVD drive. Similarly, the scanner driver just connects the scanner to the computer.
You need to use a Scanning software to use the scanner. Canon offers CapturePerfect 3, using which you scan documents, do rotation, convert to PDF etc. CP3 has option to detect the page size. CP2 is available free of cost from Canon sites. CP3 comes with the scanner.

CapturePerfect is a good software. What version are you using? What is the problem. It is easy and meets general requirements. The only problem I found with CapturePerfect is that it does not accept changes made in settings, you need to go todefault and then select the settings of your choice.
If you have installed the driver, you can also use Micorsoft Document imaging for scanning. S. Mohan

I have resolved this in the past and a new user just brought it up again.

The pafcv2.dll in Captureperfect 2 does not seem to work. If you install CapturePerfect 3 and copy the pafcv2.dll into captureperfect (c:\program files\canon electronics\captureperfect2 or whatever install path you used), you will find that you can now scan into PDF, even in batches!

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.

As per CAnon Europe site, it looks only version 3 of CapturePerfect works in Vist environment. What version do you use?

There is no mention about ISIS/TWAIN Drivers. In case you can load the drivers, you can try Microsoft Imaging to scan instead of CapturePerfect.
