Poor Scanning Quality; Unable To Scan The Image; The Recipient Does Not Receive A Transmitted Data - Sharp MX-C250 Operation Manual

Problem

Poor scanning quality.

Unable to scan the image.

The recipient does not receive a
transmitted data.
Cause and solution
The document glass or the underside of the document
feeder is dirty.
→ Clean regularly.
Original smudged or blotchy.
→ Use a clean original.
You have not specified a suitable resolution.
→ Make sure that the resolution setting in the scanner driver is
appropriate for the original.
You have not specified a suitable value for the "B/W
Threshold" setting.
→ If you are scanning with a TWAIN-compliant application, make
sure that a suitable value is specified for the "B/W Threshold"
setting. A larger threshold value makes your output darker, while
a small threshold value makes it lighter. To adjust the threshold
automatically, click the "Auto Threshold" button on the "Image"
tab of the "Professional" screen.
The brightness and contrast settings are not suitable.
→ If you are scanning with a TWAIN-compliant application and the
resulting image has unsuitable brightness or contrast (for
example it is too bright), click the "Auto Brightness/Contrast
Adjustment" button on the "Color" tab of the "Professional"
screen. Click the "Brightness/Contrast" button to adjust the
brightness and the contrast while viewing the scanned output
image on the screen.
The original is not placed face up in the document feeder
or face down on the document glass.
→ Place the original face up in the document feeder or face down on
the document glass.
The original was not placed in the correct position.
→ Place the original correctly.
Your application is not TWAIN compliant.
→ If your application is not TWAIN compliant, scanning will not be
possible. Make sure your application is TWAIN compliant.
You have not selected the scanner driver of the machine
in your application.
→ Make sure that the machine's scanner driver is selected in your
TWAIN-compliant application.
You have not specified all scanning preferences
appropriately.
→ Scanning a large area at high resolution results in a large amount
of data and extended scanning times. The scanning preferences
should be set appropriately for type of original to be scanned, i.e.,
Text, Text/Graphics, Photograph.
There is a mistake in the stored destination information
or the wrong destination was selected.
→ Make sure that the correct destination information is stored.
If there is a mistake, correct it.
