5 Troubleshooting
Calibrations
Scanner multifeed calibration should be done only when Technical
Support personnel tell you to calibrate.
The touch screen of the S2060w/S2080w scanners can be calibrated.
Again, this calibration should be performed only if Technical Support
personnel advise it and tell you how.
Roller marks appear on the paper after
scanning
Clean the rollers. See the procedures in “4 Maintenance” on page 39.
Scanning pages with wet ink will cause ink to transfer to the tires, and
from the tires to your pages. Do not scan pages unless the ink on them is
dry.
Images have black background bleed-
through
When scanning translucent paper, black bleed-through may appear on
the image. To minimize this, adjust the Contrast and Brightness values or
select Draft (Fixed) in TWAIN or Fixed Processing in ISIS to improve
the image.
Red, green or blue streaks are running
through a color photo
The scanner is dirty and needs to be cleaned. Refer to “Cleaning
procedures” on page 40.
Images have speckles Speckles happen because paper thickness is not uniform. See
“Improving image quality” on page 37.

• The scanner is USB 3.1 Super Speed compliant. It is designed to
operate with USB 3.1 or USB 2.0, but will function in a USB 1.1 port. If
you are using a USB 1.1 connection, update your USB connection.
• When scanning wirelessly, other network traffic can slow performance.
• Several settings, such as active feeding and enhanced stacking, can
slow the scanner. Experiment to find the settings that work best for you.
“Length protection active” message
shows on scanner screen
• The combination of driver settings may result in a jam message when
scanning occurs. If a jam message occurs, adjust one or more of these
settings in the scanner driver.
