Maintenance and
replacement
procedures
This section provides procedures for replacing the following parts. Use the
list below as a guideline for frequency of replacement.
• Feed Module Tires and Separation Roller – tire life will vary
depending upon paper types, environment and cleanliness. Nominal
tire life will be approximately 250,000 documents; results will vary.
Degradation of feeder performance, multiple feeds, stoppages, etc.
indicate a need to change tires. Change all the tires on the feed
module and separation roller at the same time.
• Feed Module Separation Roller – it is recommended that you install
a new feed module approximately every 5th tire change. See the
checklist included in the Replenishment Kit. Install a new feed module
and separation roller at the same time.
• Pre-separation Pad – change each time you change the tires on the
feed module and separation roller.
• Exposure Lamps – it is suggested that all four lamps be replaced
every 500 hours of operation or as necessary (i.e., as reported by the
scanner, repeated image calibration failures, etc.)
• Imaging Guides – replace when the imaging guides are heavily
scratched and defects show in the image.
This section also provides replacement procedures for the:
• Gear for Self-Centering Side Guides – a spacer is installed in the
output tray, which allows the side guides to move independently. If you
want the side guides to move together (self-centering) you can install
the geared spacer that is included with the scanner.
• Side Guides – short side guides are standard with the scanner. A set
of tall side guides is included with your scanner and can be changed
as required by your application.
