SW1 applies AC power to pulse relay SOL3 causing the hole finder pin to press against the card surface in search of a hole In the absence of previous imprints the card travels until its bottom edge contacts the registration switch actuator Further travel depresses the positioner closing SW2 Closure of SW2 applies AC power to the print solenoid providing impact force to the platen A throwout arm opens 581 immediately following registration to remove power from the print solenoid The card must be removed to reset the SW trigger As the platen strikes the card the punch assembly also driven by the platen linkage punches a hole near the top of the card s print field On subsequent registrations the hole finder pin falls into the hole nearest card bottom Further travel depresses the hole finder pin closing SW2 A new hole is punched beneath the finder pin Since the hole nearest card bottom triggers registration imprints are aligned from top to bottom as the holes move down the card Horizontal imprint alignment is accomplished by a shift assembly which is manually operated via the card receiver The card receiver may be shifted from side to side into either of two positions thereby locating the column to be Page 8800 SERIES THEORY OF OPERATION imprinted between the platen and the print wheels An imprint ribbon is automatically ratcheted forward to the next position each registration by a ribbon shift solenoi
