; TIMING CHANGES FOR B3 NECISITATED BY
; INCLUSION OF THE MOHAWK HIGH VOLTAGE POWER

;
; 1. KEEP THE EXPOSURE LAMP ON AS LONG
; THE DRIVES ARE ON.
;
; 2. PREVENT THE COROTRONS FROM GOING OFF
; IF THE PRINT SWITCH IS MADE PRIOR TO
; THE NORMAL COROTRON TURN-OFF TIME
; DURING CYCLE OUT.
;
; 3. IF THE PRINT SW IS MADE AFTER COROTRON
; TURN-OFF AND BEFORE 7.5 SEC. HAVE PASSED
; SINCE THE END OF SCAN TURN ON THE
; COROTRONS AT 7.5 SEC. AND START A SCAN
; AT 8.0 SEC.
;
; 4. IF THE PRINT SW IS MADE BETWEEN 7.5SEC.AND
; CYCLE OUT TURN ON COROTRONS AT 10.1 SEC.
; AND START A SCAN AT 10.6 SEC.

; SENSE JAM RECOVERY( POWER ON RESET) AND TURN CHARGE
; ON WITH DRIVES FOR COPY FOLLOWING A JAM TO AVOID THE
