Scanning problems
| Condition |
| Suggested solutions |
|
|
| |
The scanner does | • | Make sure that you place the original to be | |

| scanned face down on the scanner glass. | |
|
| • | 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 USB cable is connected |
|
|
| properly. |
|
| • | Make sure that the USB 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 Configuration or the application |
|
|
| you want to use to make certain that the |
|
|
| scanner job is being sent to the correct port. |
|
|
| |
The unit scans | • | Check if the machine is printing received | |

| data. If so, scan the document after the | |
|
|
| 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. |
