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. 5-7.)
–
(See “Cleaning the Retard Roller” on p. 5-9.)
• 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. 5-13.)
