- Confirm the connection
- between the ADF motor and the ADF PWB, and

- logic board.

without printing the remaining data for the
ejected paper, then printing will resume from
the next page.

It won't scan unless you have a program like picasso running on your computer to accept the scan. On the Canon you choose where you want the scanned image to go and if you choose the computer you need a program running to store or adjust the scanned image.

If you are receiving an Error Code 103 or a Paper Jam error, but there are no pages in the ADF (Automatic Document Feeder), follow the steps below:

1. Close the scanning application (such as PaperPort)
2. Turn off the scanner and the computer
3. If you have a combination ADF with a Flatbed scanner, unplug the ADF cable from the base of the scanner
4. Plug the ADF cable back in
5. Turn on the scanner power
6. Turn on the computer
7. Try scanning again

For a Paper Jam or Error Code 103, make sure that the ADF cable in the rear is connected to the scanner base. Check the flatbed to make sure that it is clear. A page incorrectly placed on the flatbed may interfere with a page feeding through the ADF.

If your scanner stops scanning due to a paper jam in the Automatic Document Feeder (ADF), a warning dialog box appears after a few moments.

To clear a paper jam:

1. Open the Automatic Document Feeder cover.
2. Remove the jammed paper and close the cover.

If you are receiving a paper jam error, or if the scanner is running continuously, check to make sure the paper sensor arm is not stuck down.

1. Open the Automatic Document Feeder cover.
2. Look for the small black plastic arm
3. When you press on this arm, it should move freely up and down
4. If the arm is stuck down, please contact Technical Support for troubleshooting options
5. Close the ADF cover.

This is a known problem with the scanner. Use PixEdit to scan which comes around this problem so the scanning terminates OK after the ADF goes empty.

Have you tried lowering the resolution of the scanned document?

Did you install the full printer driver package?
The printer has to start the appropriate scanning SW on your PC.

1. From the MP Navigator screen, select "Scan with Scanner Driver" in lower left corner.
2. When in ScanGear MP, select the Advanced Mode tab
3. At Input Settings, select Document (ADF) for document type
4. Set paper size in next window
5. Click Scan button at bottom

Open the back door under the rear feed-in slot and check for distorted paper there.
I reuse the backside of lots of paper so sometimes get it jambed up back there.
