Replacement
procedures This section provides procedures for replacing the following parts: the
feed rollers, the pre-separation pad and the imaging guides. When
replacing parts, turn the scanner off by pressing the power switch
located in the back of the scanner and unplug the power cord from the
wall outlet.
Replacing tires With proper cleaning, tire life of the pick roller, drive roller and
separation roller is approximately 600,000 pages. Different document
types, the condition of the documents being scanned, and the volume
of scanning may alter that estimation.
All tires on the pick roller, drive roller and separation roller should be
replaced at the same time. See the section entitled, “Cleaning the feed
rollers” earlier in this chapter for procedures on removing and installing
the feed rollers.
1. Open the scanner cover.
2. Remove the pick and drive rollers.
3. Gently remove each tire from the pick and drive rollers and dispose
the old tires.
4. Install each new tire by gently pulling it over the core. The tires do
not need to be installed in any specific orientation.
IMPORTANT:Do not overstretch the tire; it may tear.
5. Re-install the pick and drive rollers.
6. Pull the separation roller door forward and hold it in place while you
remove the separation roller; gently release the separation roller
door back in place.
7. Remove each tire from the separation roller and dispose the old
tires.
8. Re-install the separation roller and verify that the separator roller is
seated properly.
9. Close the scanner cover.
10. When all tires have been replaced, reset the maintenance reminder
by clicking on the Replace Feed Rollers link on the Maintenance
monitor.
11. Click Yes on the dialog box to confirm the tires/rollers have been
replaced. The reminder will be reset for the next required
maintenance session.
