Data cartridges, like all magnetic media, require periodic cleaning and retensioning to remove surface debris and dirt that interferes with proper head/tape contact. The 3491e automatic cleaner thoroughly cleans and retensions all IBM and compatible half-inch data cartridges which conform to IBM publication GA 32-0048 (3480, 3490 & 3490e).

The machine uses a vacuum-assisted gemstone-cleaning blade to remove contamination from the oxide surface of the tape. Each blade is good for 2,000 passes. The machine automatically indicates when the blade requires changing.

Two cleaning tissues are used to remove contamination from both sides of the tape, and the machine automatically indicates when the tissue cartridges require changing.

The machine drive design incorporates hydrostatic air bearings to minimize tape contact and friction. It uses microprocessor controlled tension transducers to provide accurate winding and tensioning. Air filters and ionizers are included to purify the environment and eliminate static. The microprocessors automatically set tension per ANSI standards for each type of cartridge.

Autoloader - Ten Cartridge Magazine

The 3491e is fast enough to clean ten (10) tapes unattended in less than half an hour. Cartridges are housed in a removable ten-cartridge magazine that is placed in the loading mechanism for processing. Each cartridge is then automatically positioned, loaded, processed, and unloaded sequentially. 

Optical Scanner (OPTION)

This optional feature provides detection and recording of any physical tape imperfection. Wrinkles, edge stretches, oxide voids, shedding oxide, or any anomaly on the oxide surface is detected. Defects .0025 inches or larger are detected.
