3.3 PAPER FEED CHARACTERISTICS
Paper is fed in a forward direction when the motor shaft is rotating in the normal direction
(clockwise) when seen from the motor gear side.
The motor is driven by a 2-2 phase excitation, constant current chopper method and feeds
paper 0.125 mm (equivalent to a single dot pitch) every two steps of the motor drive signal.
To prevent deterioration in printing quality due to backlash of the paper feed system, the motor
should be driven 40 steps in a reverse direction and then 40 steps in the normal direction during
initialization or after backward feeding.
During paper feeding, the motor should be driven lower than the value obtained by equation (1).
Equation (1):
Vp
×
165 - 220 (pps) (max.1000 (pps) )
During printing, the motor drive frequency should be adjusted according to working conditions
such as voltage, temperature, number of activated dots, etc. (For details, see
CHAPTER 5
DRIVE METHOD
.)
Do not print while the motor is rotating in the reverse direction.
