Cleaning the feed rollers Feed rollers include the skimmer (pick and drive) roller and separator roller. All feed rollers should be cleaned and/or replaced at the same time to ensure optimal scanner function. Maintenance reminder intervals (both cleaning and replacing) are based on all feed rollers having the same life cycle. Cleaning the skimmer rollers The skimmer module is comprised of two rollers; the pick roller and the drive roller. Both rollers contain two, removable rubber tires. One outer edge of each tire contains at least 3 dots. Skimmer Pick roller Release lever Drive roller Spring-loaded release These dots are used as a point of reference for correctly installing the tires on the roller and also the rollers into the skimmer housing. When installing the tires, the 3 dots should always be facing left. If the tires or rollers are installed incorrectly in the skimmer housing, the skimmer module will not function properly. All four tires and the separator roller should be replaced at the same time. When the skimmer rollers become dirty, they may begin to slip on paper or cause multifeeds. To prevent feeding problems and avoid rubber tire replacements, it is recommended that you clean the skimmer rollers (tires) every 10,000 pages or as needed. Different document types, the condition of the documents being scanned, and the volume of scanning may require more frequent cleanings. 5-4 A-61662 April 2010
