Replacing the Transport Rollers
As the rollers start to wear out, feeding quality declines, and document feed errors, such as paper jams, become more likely.
If document feed errors continue to occur after cleaning the rollers, purchase the Roller Replacement Kit and replace the transport rollers (pickup,
feed, and retard rollers).
Roller Replacement Cycle
The feeding rollers are consumables that must be replaced after
feeding about every 500,000 pages.
When the rollers have fed more than 500,000 pages, a roller
replacement message appears on the display panel whenever the
scanner is turned ON. When the scanner is configured to reboot with
the computer, a roller replacement message also appears on the
computer screen.
IMPORTANT
• When the roller replacement message appears, purchase the Roller
Replacement Kit and replace the rollers by following the relevant
steps in the cleaning procedures.
–
(See “Cleaning the Pickup and Feed Rollers” on p. 92.)
–
(See “Cleaning the Retard Roller” on p. 96.)
• When the rollers start to wear out, problems such as paper jams and
document misfeeds may occur more frequently. If this happens,
replace the rollers, regardless of the page count of the roller usage
counter.
• Messages on the display panel can be cleared by pressing the
Stop key. However, the messages will continue to be displayed
each time the scanner is turned ON until the roller counter is reset.
• Make sure to reset the roller counter when replacing the rollers.
(See “Checking and Resetting the Page Counter” on p. 100.)
