Replacing the Rollers
The feed rollers (pickup rollers, feed rollers, and retard rollers) are consumables.
The feed rollers need to be changed periodically to maintain scanning quality.
When to Replace the Rollers
If the total number of scanned documents exceeds 250,000, a message for roller
replacement appears when you restart the computer. In this case, buy the
exchange roller kit and replace the feed rollers (pickup rollers, feed rollers, and
retard rollers).
Be sure to reset the counter after changing the counter.
Windows NT do not support a function to display a message for roller replacement.
To confirm the total scan, check “Total Scanning Count” in the “About” dialog box of
the ISIS/TWAIN driver and replace the feed rollers if the count shows around 250,000
scans.
Contact your sales representative for information about exchange roller kit (pickup
rollers, feed rollers, and retard rollers).
