Paper Feed Trouble
If the document is not fed properly or the detection functions do not work smoothly, remedy the problem by following the remedies described below.
Condition | Paper jam has occurred. |
Cause and remedy | ● Check the document to see if the size and thickness of |
| the document are within the ranges supported by the |
| scanner, and to see if the quality of the document paper |
| is appropriate. |
| Refer to cautions on handling documents. (See “About |
| Documents” P. 42) |
| ● Document slipping may be causing a paper feed error |
| (See “Paper Feed Adjustment” P. 36). |
| ● The intermediate unit is not attached properly. Properly |
| attach the intermediate unit. (See “Attaching the |
| Intermediate Unit” P. 67) |
| ● Dirty or worn rollers inside the scanner cause paper |
| jams. |
| Clean rollers if dirty (See “Cleaning the Scanning Glasses |
| and Rollers” P. 75). |
| Worn rollers must be replaced. Contact a Canon service |
| department. |
Condition | The document tray does not rise and you hear a |
| clicking sound. |
Cause and remedy | The weight of the loaded paper sometimes increases due to |
| the environment in which the document is stored. If this |
| happens, the weight of the paper will exceed the maximum |
| allowed stacked weight even if the number of stacked |
| sheets is below the maximum, and sometimes prevent the |
| document tray from rising. Reduce the number of document |
| sheets loaded on the document tray and scan the document |
| again. (See “Document Loading Precautions” P. 43) |
Condition | Double feed error occurs even though documents are |
| not being |
| feed) |
Cause and remedy | If the size and thickness of the paper on which the Function |
| Sheet is copied differs from that of the document to be |
| scanned when the Function Sheet is used, the scanner |
| erroneously judges this to be a double feed, and this error |
| occurs. If this happens, turn double feed detection OFF, and |
| scan the document again. Or, copy the Function Sheet on |
| paper of the same size and thickness as the document, and |
| use that copy. |
