3.5.21. Multi-purpose Tray (MPT) Paper Pickup Motor Drive Circuit
This is for controlling the stepping motor (7.5°/step two-phase) which feeds the media from the multi-purpose tray. This circuit
mainly consists of ASIC (IC14), IC16, IC10(motor driver IC). There are the 2 drive method (2-phase drive and 1-2 phase drive) for
driving the MPT paper pickup motor. The drive method is selected based on the media type and media feeding speed (600dpi or
1200dpi). The 2-phase drive is for feeding the standard recommended paper (except envelope, OHP, label) at 600dpi feeding
speed. The 1-2 phase drive is for feeding the standard recommended paper at 1200dpi feeding speed, the envelope, OHP and
label.
MPTMA, MPTMB:
These are the phase selecting signals for the channels A and B.

MPTMNA, MPTMNB :
These are for controlling the power output for the channels A and B. When this signal MPTMNA (MPTMNB) is the low, the
power is outputted to the phase A (B) and phase A- (B-).

MPTMCUR, MPTMON :
These signals are for controlling the current from the motor driver IC (IC10) to the motor. The current varies based on the status
of these signals. The following indicates the current that is supplied to the motor (on the assumption that the supplied motor
current is “I”) when the MPTMCUR and MPTON are the low.

VREFCNT :
These signals are for controlling the current from the motor driver IC (IC10) to the motor when the ADU is activated. When the
ADU is activated, the VREFCNT signal is changed from a low to a high. As a result, the current from IC10 to the motor is
decreased because the voltage of VREF1 (VREF2) is lowered.
