This chapter describes the required cleaning and maintenance procedures for
the
Kodak
i4250, i4650 and i4850 Scanners. The frequency of these
procedures will vary with different scanning environments, paper types and
image processing requirements. High volumes of scanning will demand more
frequent cleaning of the scanner and more frequent replacement of
consumables. Lower scanning volumes will allow longer times between these
activities. Refer to the “Cleaning frequency chart” on the next page for cleaning
guidelines. However, you will need to determine what works best for you.
Years of production scanning experience proves that properly cleaning and
maintaining your scanner will result in scanning more paper in less time with
less issues. A properly maintained i4250, i4650 and i4850 Scanner will provide
years of trouble-free operation.
Scanner consumables (tires, pre-separation pads, etc.) and cleaning supplies
are available from your scanner supplier. Consumables are sold in kits of
various sizes. The kits contain the proper mix of tires, rollers, and pre-
separation pads so you can easily replace them at the recommended rate. For
example, only replacing the tires and never replacing the separation roller will
eventually minimize scanner performance. Replacing the consumables at the
recommended frequency will ensure the best performance.
