Scanning problems

|
|
The scanner does not | • Make sure that you place the original to be |

| • There may not be enough available memory |
| to hold the document you want to scan. Try |
| the Prescan function to see if that works. |
| Try lowering the scan resolution rate. |
| • Check that the machine cable is connected |
| properly. |
| • Make sure that the machine cable is not |
| defective. Switch the cable with a known |
| good cable. If necessary, replace the cable. |
| • Check that the scanner is configured |
| correctly. Check scan setting in the |
| SmarThru or the application you want to use |

| sent to the correct port (for example, |
| USB001). |

| received data has been printed. |
| • Graphics are scanned more slowly than text. |
| • Communication speed slows in scan mode |
| because of the large amount of memory |
| required to analyze and reproduce the |
| scanned image. Set your computer to the |
| ECP printer mode through BIOS setting. It |
| will help to increase the speed. For details |
| about how to set BIOS, refer to your |
| computer user’s guide. |
