REPLACEMENT OF CONSUMABLES
In this section the instructor will identify all the consumables (parts of the scanner that will wear
out during normal use) and instruct you on the proper procedures for the replacement of these
items. Just as changing the oil and replacing worn tires on your car is necessary to keep it
running properly, the timely replacement of the scanner’s consumables is critical to its
performance. As an operator, you will experience fewer paper feeding problems if the
consumables are replaced when they are worn.
Open the User’s Guide to the Replacement Procedures in the Maintenance chapter.
Pre-separation pad: it is recommended that you change
the pre-separation pad approximately every 250,000
documents.
Feed module tires and separation roller tires: tire life
will vary depending upon paper types, environment and
cleanliness. Nominal tire life for clean, non-NCR, US letter
size, 20 lb bond paper, documents fed in landscape
orientation is approximately 600,000 documents; results
will vary. Degradation of feeder performance, multiple
feeds, stoppages, etc. indicate a need to change tires.
Change all tires on the feed module and separation roller
at the same time.
Feed Module: replace after every 4th replacement of tires,
approximately after 2,400,000 scans. Install a new feed
module and separation roller at the same time.
Separation roller: replace after every 4th replacement of
tires, approximately after 2,400,000 scans. Install a new
feed module and separation roller at the same time.
