Paper feed issues Paper jamming, skewing, misfeeds, or multiple-page feeds ● Scanning damp or wet pages can cause paper jams. Make sure that the pages being fed are completely dry (toner is dry, there are no wet substances such as glue or correction fluid). ● Check that all rollers are in place and that the roller door and document feeder hatch are closed. ● If the pages look skewed as they feed into the scanner paper path, check the resulting scanned images in the software to ensure that they are not skewed. ● The pages might not be placed correctly. Straighten the pages and adjust the paper guides to center the stack. ● The paper guides must be touching the sides of the paper stack to work properly. Please ensure that the paper stack is straight and the guides are against the paper stack. ● The document feeder or output tray might contain more than the maximum number of pages. Load fewer pages in the document feeder, and remove pages from the output tray. ● Clean the scanner paper path to help reduce misfeeds. If misfeeds still occur, clean the rollers. If misfeeds still occur, replace the rollers. Paper does not feed from the scanner Reload the pages into the document feeder, ensuring that they make contact with the rollers. The document feeder hatch might not be securely latched. Open the hatch and then close it, pressing firmly on both sides to ensure the hatch is closed. A problem with the scanner hardware might exist. Follow this procedure to test the scanner: 1. Ensure that the power supply is securely connected between the scanner and a live electrical outlet or surge protector. Check that the green LED on the power supply case is on to verify that the power supply is functional. 2. If the power supply is connected to a surge protector, ensure that the surge protector is plugged into an outlet and turned on. 3. Press the Power button to turn off the scanner, disconnect the power supply from the scanner, and then turn of the computer to which the scanner is connected. Wait 30 seconds, reconnect the power supply to the scanner, press the Power button to turn on the scanner, and then turn on the computer. 4. Try to rescan. Originals are curling up in the scanner output tray. Under dry conditions, lightweight originals such as those printed on carbonless copy paper may curl in the output tray. To minimize curl, flatten curled edges on the originals before placing them in the document feeder. 44 Chapter 4 Solve problems ENWW

Paper feed issues
Paper jamming, skewing, misfeeds, or multiple-page feeds
●
Scanning damp or wet pages can cause paper jams. Make sure that the pages being fed are completely dry
(toner is dry, there are no wet substances such as glue or correction fluid).
●
Check that all rollers are in place and that the roller door and document feeder hatch are closed.
●
If the pages look skewed as they feed into the scanner paper path, check the resulting scanned images in
the software to ensure that they are not skewed.
●
The pages might not be placed correctly. Straighten the pages and adjust the paper guides to center the
stack.
●
The paper guides must be touching the sides of the paper stack to work properly. Please ensure that the
paper stack is straight and the guides are against the paper stack.
●
The document feeder or output tray might contain more than the maximum number of pages. Load fewer
pages in the document feeder, and remove pages from the output tray.
●
Clean the scanner paper path to help reduce misfeeds. If misfeeds still occur, clean the rollers. If misfeeds
still occur, replace the rollers.
Paper does not feed from the scanner
Reload the pages into the document feeder, ensuring that they make contact with the rollers.
