To replace the pick and drive roller tires, perform the following:
1. Power OFF the scanner (see 1.4.2 Scanner Back, “
Power Switch” on page 11)
2. Open the scanner’s transport cover (see 1.4.1 Scanner Front, “
Transport Cover” on page 7
and “
Transport Cover Release Levers” on page 7)
3. Remove the skimmer rollers (see “Cleaning the Skimmer Rollers” on page 61)
4. With the skimmer rollers removed, make note of the position the old tires are in, i.e. what side
the markers are on (in the image, the markers are red in color)
- Work the old tires off of the shaft with your fingers, leaving the
shaft in the same position as a reference for putting on the
new tires
- Another point of reference for correctly installing the tires is:
the side of the tire containing the markers should also be on
the same side that the metal clutch of the roller is visible on
(the opposite side of the roller shaft contains a plastic bush-
ing) - this applies for both tires for each roller (drive and pick)
5. Dispose of the old tires
6. Install new tires with tire markers facing the same side the metal clutch is visible on, taking
care to position the tires flush against the inside lip of the plastic hub
7. Install the skimmer rollers (see “
Cleaning the Skimmer Rollers” on page 61)
8. Replace the separator roller (see “
Replacing the Separator Roller” on page 67)
9. Close the scanner’s transport cover
10. Once all four tires and separator roller have been
replaced, reset the maintenance reminder for
replacing the Feed Rollers located in the
Maintenance Monitor section of the NOU’s Home
Screen
- With the NOU active and communicating with
the scanner (see ”2.2
Ngenuity Operator
Utility” on page 29), click on the Replace
hyperlink associated with “Replace Feed
Rollers” in the Maintenance monitor of the
Home screen
- A confirmation dialog window will display.
Confirm the Feed Rollers have been replaced
by clicking the YES button. This will reset the
reminder to begin monitoring for the next
required maintenance session
