Resolving issues with the ADF
This section contains issues that might occur when you are using the
automatic document feeder (ADF).
The ADF is feeding multiple sheets, skewing pages, or jamming
frequently.
If the pages look like they are skewing as they feed into the ADF,
check the resulting scanned images in the software to ensure
they are not skewed.
The item might not be placed correctly. Straighten the item and
adjust the guides to center the stack.
The maximum number of pages the ADF input tray and output
bin can hold is 25, depending on the type of media being loaded.
Make sure to load only 25 or fewer pages in the input tray, and
remove pages from the output bin if they are stacking up to a pile
of more than 25.
The item loaded might not meet the specifications for the ADF.
Make sure the type of media being loaded meets required
specifications. See "Items for the ADF" on page 17.
When using the ADF, the scanner does not feed the item at all.
The hatch might not be securely latched. Open the hatch, and then
close it, pressing firmly. See "To clear jams at the start of a page"
on page 108 for illustrations.
An item loaded in the ADF keeps jamming.
The item does not meet the guidelines for the ADF. See "Items
for the ADF" on page 17.
The item might have something on it. Make sure you have
removed anything such as staples and self-adhesive notes on
the item. See "Selecting and preparing items" on page 17.
The item is too small. The ADF can handle items as small as
88.9 by 127 mm (3.5 by 5.0 inches). Use the glass to scan.
The item is too large. The ADF can handle items as large as 216
by 355.6 mm (8.5 by 14 inches). Use the glass to scan the item
in sections.
