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
make sure the left edge of it is placed against the left side of the
input tray.
●
The maximum number of pages the ADF input and output trays
can hold is 50, depending on the type of media being loaded.
Make sure to load only 50 or fewer pages in the input tray, and
remove pages from the output tray if they are stacking up to a
pile of more than 50.
●
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 7
.
When using the ADF, the scanner does not feed the item at all.
The document input tray might not be securely latched. Raise the
hatch and the input tray, and then lower them, pressing firmly. See
"To clear jams at the end of a page" on page 94
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 7
.
●
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 7
.
●
The item is too small. The ADF can handle items as small as
148.5 by 210 mm (5.9 by 8.3 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.
The bottom of the scanned image is cut off.
●
The ADF can handle items up to 355.6 mm (14 inches) long. If
the item is longer, scan it in sections on the glass. If the item is
the correct length, choose the correct page size setting in the
ADF dialog box prompt before scanning.
●
If sent to a printer, the item might be too complex (require too
much memory) for the printer to process. If possible, choose a
printer with more memory. Or, select a lower resolution or
different output type.
Pages scanned from the ADF only appear as vertical lines, or all one
color.
There might be a page on the scanner glass. Raise the ADF unit
and remove any pages on the scanner glass.
