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. A-61169 July 2003 5-11
