D. SALES NUMBER ADVANCING
MECHANISM INSPECTION.
1. Sales number advancing mechanism, Figure
17, is tripped when printing occurs. The
movement of the sale advance wheel starts
immediately with rotation of the input shaft and
completes transfer within 1/4 of a revolution. If
the sales number on the right-hand wheel does
not align properly with the other wheel, it must
be adjusted.
2. To align the wheel, position the tail of the
clutch spring in different slots of the transfer
disc until properly adjusted.
