Common causes of jams
|
|
|
|
|
| The paper length and width guides are not adjusted correctly.
|
|
| Adjust the guides so they are against the paper stack.
|
|
| The media does not meet specifications.
|
|
|
| You are using media that has already passed through a printer or copier.
|
|
| Do not use media that has been previously printed on or copied.
|
|
| An input tray is loaded incorrectly.
|
|
| Remove any excess media from the input tray. Make sure that the stack is below the maximum stack height mark in the tray. See Load paper and print media.
|
|
|
|
| The input-tray guides are not adjusted correctly. Adjust them so they hold the stack firmly in place without bending it.
|
|
| The media is binding or sticking together.
|
|
| Remove the media, flex it, rotate it 180 degrees, or flip it over. Reload the media into the input tray.
|
| NOTE:
|
Do not fan paper. Fanning can create static electricity, which can cause paper to stick together.
|
|
| The media is removed before it settles into the output bin.
|
|
| Wait until the page completely settles in the output bin before removing it.
|
|
| The media is in poor condition.
|
|
|
| The internal rollers from the tray are not picking up the media.
|
|
| Remove the top sheet of media. If the media is heavier than 163 g/m2 (43 lb), it might not be picked from the tray.
|
|
| The media has rough or jagged edges.
|
|
|
| The media is perforated or embossed.
|
|
| Perforated or embossed media does not separate easily. Load sheets one at a time.
|
|
| Paper was not stored correctly.
|
|
| Replace the paper in the trays. Paper should be stored in the original packaging in a controlled environment.
