I press scan but nothing happens I scan on cannon Mp 160 and I cant scan with my pc

Operate the scanner from the computer not the printer.
Have you loaded the MP Navigator progam from the cd supplied with the printer?
If not, do that first and then follow the steps below.
Double click MP Navigator icon on desktop.
Choose "custom scan with one click "
Save to pc. (" attach to email "only works on windows mail)
Open saved location and rename.
Write your email & click on insert drop down box
Click on "pictures inline "
Open pictures.
Open MP Navigator folder
Choose scanned item by name
Click on open box
Scan will appear under the text in your email.

I think I know what you are asking. You want to scan in 4 documents, but end up with only one pdf file? You can scan them in as 4 files, and then combine the files into one with the right software. There are some free tools that can do this, but they are not as easy to use as software you would have to pay for. No, there is at least one free web-page-based utility to do this now. You have to decide which utility you want to use, but here is you you would find some: http://www.bing.com/search?setmkt=en-US&q=combine+pdf+files+into+one

Something is wrong with the scanner or communication to the scanner

Uninstall all your drivers (and delete the preferences) and download the Mac drivers from this link. The drivers that came with your printer were developed before Snow Leopard came out.

Make sure the scanner is connected to your laptop/PC before you press 'scan'.
Pressing the scan option will start Canan's software MP Navigator for scanning. You can also start MP Navigator on your PC and then start scanning directly from your program or from the printer button.

so simple
open the photoshop then click import then usb scanner then it will open the scanner window

CANNON MP 520 PRINTER HAS FROZEN PLEASE HELP TRYED TURN OFF

try checking if you have completely installed all the drivers for your printer. scanning and copying dont usually needs drivers because you can do that even without a computer. but scanning requires your scanner to be read by your pc. try checking for the scanner driver from the cd that came from your printer.

some printers can detect that the cartridges are refilled based ona barcode or scanning of the cartridges. Does this Cannon have ink tanks or ink cartridges. If it has intakes then the print head needs to be cleaned wth rubbing alcohol and a q-tip. If they are cartridges then it would be good just to buy the original cartidges. As far as the scanning goes this can be a direct connection to the printer going through maintenance. If it continues to not scan then you may need to uninstall the scanner. see if the scanner shows up in your scanners area. if not then it will need to be re-installed.
