Troubleshooting Guide

555

Ensure that the scanner sharing feature is disabled when you use Mac OS X before

you scan documents via an ICA compatible application such as Image Capture.

The printer does not support the scanner sharing feature of Mac OS X. Select a

printer which is directly connected to the computer via USB or wired /wireless

LAN and scan documents.

The printer scans very slowly.

Graphics are scanned more slowly than text when using the

Scan to

E-mail

Scan to Network

feature.

Communication speed becomes slow in scan mode because of the large amount of

memory required to analyze and reproduce the scanned image.
Scanning images at a high resolution takes more time than scanning at a low

resolution.

Document misfeeds or multiple feeds occur

in the DADF.

Check whether the DADF roller assembly is installed properly.
Ensure the document’s paper type meets the specifications for the printer. See

"Supported Paper Types" for more information.
Check whether the document is properly loaded in the DADF.
Ensure that the document guides are adjusted properly.
Ensure that the number of document sheets do not exceed the maximum capacity

of the DADF.
Ensure that the document is not curled.
Fan the document well before loading it in the DADF.

Vertical blanks or streaks appear on the

output when scanned using the DADF.

Clean the DADF glass.
Clean inside the printer by using the cleaning rod. See "Cleaning the Raster

Optical Scanner (ROS) Window."

A smear appears at the same location on the

output when scanned using the document

glass.

Clean the document glass.

Images are skewed.

Ensure that the document is loaded straight in the DADF or on the document

glass.

Diagonal lines appear jagged when scanned

using the DADF.

If the document uses thick media, try scanning it from the document glass.

• "Device can’t be set to the H/W mode you

There may be a copying or printing job in progress. When the current job is

complete, try the job again.
The selected port is currently being used. Restart your computer and try again.
The cable may be improperly connected or the printer may be turned off.
The scanner driver is not installed or an operating environment is not set up

properly.
Ensure that the port is properly connected and the printer is turned on. Then

restart your computer.
Check that the USB or Ethernet cable is connected properly.
