Lever Motor Drive Circuit
This printer has a DC type lever motor for the purpose described below.
❏
Adjustment of paper path changeover timing
❏
Adjustment of shaft rotation position
Rotation of the lever motor starts changeover of the paper path and the platen open/close
operation. An NPN Darlington transistor is used for lever motor drive. Due to the structure of
the lever motor, a brake circuit is not required. The lever motor is driven using the ELV_M1
output signal from the GA.
The lever motor rotates when LEV_M1 = LOW. The motor cannot be driven when the VCC-
PWR is not being supplied. Furthermore, the Q41 NPN Darlington transistor incorporates a CE
Zener to perform kickback protection.
