Though high-performance scanners are designed for long-term use, they contain consumable parts that wear naturally over relatively shorter periods of time. Much like the air filter or spark plugs in your car, these parts are excluded from warranty and service contracts. Fortunately, when maintenance to your scanner is required, more often than not, it's a simple matter of cleaning or replacing a worn consumable. By utilizing the ScanAid kit for preventative maintenance, you can ensure your scanner will continue to operate at the high level of performance as when you initially purchased it. This package includes: 5 pad assemblies, 3 pick rollers, 1 chute roller, 1 blow brush, 2 F1 cleaners, 1 F2 cleaner, 3 10-packs of cleaning paper, 2 20-packs of cleaning cloth, 2 100-packs of cleaning swabs, cleaning instructions.
