Regular Maintenance 67
Removing and Attaching the Rollers
Follow the relevant procedure to remove and attach the pickup roller, feed
roller, and retard roller when you clean them or replace them.
IMPORTANT
Feed rollers are consumable parts. When the rollers start to wear out, paper
jams and misfeeds may occur more often. When this happens, buy a exchange
roller kit, and replace the pickup roller, feed roller, and the retard roller.
CAUTION
• Turn ON the power to the scanner to remove or attach the
pickup roller. Be careful when working on the scanner when the
power is ON.
• Do not use excessive force when removing or attaching the
rollers. Doing so may damage them.
Roller Replacement Message
When the number of pages scanned has exceeded 250,000 pages, a roller
replacement message appears on the computer when it is started. Buy a exchange
roller kit, and replace the pickup roller, feed roller, and the retard roller.
IMPORTANT
• If misfeeds happen often, check the rollers for wear, and replace them if
necessary before the message is displayed.
• Be sure to reset the counter when you replace the rollers. (See “Resetting
the Counter,” on p. 68.)
• Windows NT does not support the roller replacement message display.
Check the number of pages that have been scanned in the “Total Scanning
Count” in the version information for the ISIS/TWAIN driver, and use
250,000 pages as a guideline for replacing the rollers.
