If I scan A4 dokument with SmartThru4, everything goes well as usual, but in the end I get only blank white page, so it scans document, but cannot show the image of scanned A4 . Also if I copy A4 text document I´ll get black page

Two possible solutions to your problem.
If you are talking about grabbing more sheets than one from the tray, you need to make sure the tray guides are up flush against the paper.
If on the other hand you are talking about scanned/copied jobs, check the setting for your scanner, it may be set to letter size which is longer than A4, so the machine thinks it needs another sheet to complete the job causing a blank page to be sent.
Hope this helps

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.

The most common cause of blank (void) lines on a scanned document is from whiteout on the glass where the page is scanned when using the document feeder.
If there is a clear mylar sheet on the bottom of the document feeder, the whiteout may be there instead.

If there was dirt or a dark smudge on the glass (or mylar), it would show up as a black line, but whiteout is white, and shows up as a void (blank) line.

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 ..

If line is vertical.

Try scanning a bigger document. Use a blank page big as the scan capacity and scan the blank page.

If for example you are using an a3 scanner, scan a blank A3 page.

When scanning blank page set resolution to an high value, so that you does not lose pixels.

Check scan result, and explore the whole document using zoom to see if the line is still present on the test scan of the blank page.

If there is still the line, then it is either a scanner dirty, probably inside glass, or a dafective sensor on CCD sensor array.

If there is no line, then the problem is usually depending on the software.

In that case uninstall the software and install it again.

If that is not enough to fix the problem, try uninstalling software, doing a system restore to a date before the problem started , and then installing software again.

If the line is horizontal , that is usually a loss of power on the high voltage to lamp.
Try reinstalling software first, if that does not fix the problem , and line is horizontal, then it is fault mentioned above.
Horizontal lines at the end of a document may also be caused by faulty scanner control board, or scanner going out of memory.

Hi,

Scanner contains Unlock botton below it, just unlock it it will scan fine.

Try scanning a full page (A3) at different levels of contrast and in the Automode also, in color and Mono. Check the output to see if it is software or hardware issue.

Scan all, then copy to the word document. You can edit your file into small so that you can put several file in single pages.

I just did it then! With help from solution posted Feb 08 leave the acual scanner alone can be done from the computer. Steps:

1. Go to - start - control panel - printers & hardware - scanners.
2. Once inside the scanners folder just click once on the scanner icon (mine is called WIA Canon) so it is highlighted.
3. Then click on the toolbar 'File' > 'scan', then select the correct program from the list (mine was MP Navigator 2).
4. Use the MP Navigator program to select "scan photo/document", follow the instructions. At the bottom if the window that is open you can change the document type to PHOTO or DOCUMENT!

This is where the problem lies it is scanning the document as a photo which is why it is coming out as multiple documents.
