2. GENERAL DESCRIPTION
2.1 OPERATION OF ZERO-START PRINTER
The SERIES 788800 Ticket Printer (Zero Start) mechanically records and prints digital information
delivered to its drive shaft. This shaft positions the print wheels according to the ratio of internal and
external gears. Reset and print operations are manually actuated.
The zero-start printer is so-named because it begins to count at zero, and returns to zero when reset.
The printer total is the amount of delivery.
2.1.1 Drive
The shaft, figure 2, on the bottom of the printer is driven by a bevel gear from the meter-register or
other equipment. The printer’s bevel gear and shaft assembly turns in a counter-clockwise direction.
The internal bevel gear on the shaft drives the clutch assembly, associated pinions and the gear
assembly of the right-hand wheel.
Fig. 2: Drive Train
The zero-start clutch assembly prevents the printwheels from turning in a reverse
direction.
