Chapter 2 Principles of Operation
2.1.07 Line Feed Circuit
Whenever it is in a stopped position, the line feed motor shaft is held stationary by +8vdc, which is
enabled by the LFCHOP Signal from Q2. The holding current is approximately 30 ma.
During a line feed operation, the line feed motor is driven by +38 vdc in accordance with the LFOVDV
signal. The signals LF - Phase 01 and LF - Phase 04 establish the proper phase relationship for driving
the motor. However, the line feed motor uses Phase 1 - 4.
