ABSTRACT:
A tape drive (20) detects engagement of scanner cleaning assembly (200) with a scanner (90). A cleaning engagement detector (111) uses rotational velocity of the scanner (90) in order to detect engagement of a cleaning wheel (204) with the scanner (90). In particular, cleaning engagement detector (111) detects engagement when a rotational period of the scanner (90) increases by a predetermined amount. When the cleaning engagement detector (111) detects engagement of the cleaning wheel (204) with the scanner (90), a microprocessor (100) controls a duration of the engagement, thereby avoiding wear both of the cleaning wheel (204) and of the heads on the scanner (90).
