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.

4

2.1.2 Reset

During printing operation, the printwheels are reset to zero through rotation of the reset gear-train and
reset shaft, figure 3. During the “Print In” cycle, one complete clockwise revolution of the reset drive
gear turns the reset shaft gear and reset shaft to zero the print wheels.

2.1.3 Printing
In printing operation, a ticket is inserted into the slot of the ticket tray until it bottoms on the internal

stop.
a. As the printing crank is turned, the reset drive gear, figure 3, makes one complete clockwise

revolution until a positive stop is reached. As the ticket tray moves into position, the seal pin
pierces the ticket, holding it in place. This initial printing is made with wheels at zero.

b. At the completion of delivery, the crank is turned in a clockwise direction one complete turn until

the stop is again reached. During this cycle the second printing is made recording the amount of
delivery. At the end of the print cycle the ticket tray returns to original position and the seal pin
releases the ticket.

5

2.2 OPERATION OF ACCUMULATIVE PRINTER

The SERIES 788801 Ticket Printer (Accumulative) 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. Print operations are manually actuated.
The accumulative printer is so-named because it is a non-resetting type that begins the count at the
accumulated total of the last delivery, prints it, accumulates a new total for the new delivery and prints
it. The amount delivered must be calculated by the operator.

2.2.1 Drive
The shaft, figure 4, 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.

2.2.2 Printing
In printing operation, a ticket is inserted into the slot of the ticket tray until it bottoms on the internal

stop.
a. As the printing crank is turned, the reset drive gear, figure 5, makes one complete clockwise

revolution until a positive stop is reached. As the ticket tray moves into position, the seal pin
pierces the ticket, holding it in place. This initial printing is made with wheels as they were at the
completion of the last delivery.

b. At the completion of delivery, the crank is turned in a clockwise direction one complete turn until

the stop is again reached. During this cycle the second printing is made recording the accumulative
total of this delivery. At the end of the print cycle, the ticket tray returns to original position and the
seal pin releases the ticket.

4. CLEANING AND LUBRICATING

4.1 GENERAL

Although the printer, when manufactured, is adjusted and lubricated, it does require periodic cleaning
and lubrication to give maximum service. Judgement of the intervals at which the printer requires such
service must necessarily be left to individual users, due to varying conditions of service. Under normal
circumstances, this will be no more than twice a year, or after each 100,000 units of measure
delivered.

4.2 CLEANING

a. Remove cover and case-assembly and detach printer from meter-register per Section 3.
b. Flush printing wheels, reset gears, and all drive gears with cleaning solvent. Blow out surplus

solvent with compressed air and lubricate unit.
c. If printing wheels are extremely dirty, a small brush may be used to scrub the figures.

CAUTION: DO NOT USE A WIRE BRUSH.

4.3 RECOMMENDED LUBRICATION

OIL : Anderol L-401-D or equivalent (Temperature range -60C to +253C).
GREASE : Anderol L-795 or equivalent (Temperature range -54C to +145C).

All lubricants used in the printer must be of a type which remains fluid over the full
temperature range to which the printer will be subjected. Also they should not oxidise or
dry out, leaving a gummy or perceptible residue

4.4 LUBRICATION POINTS

(Figures 4 and 5)
Apply recommended or equivalent oil to bearing surfaces of all shafts, studs, and bosses on which
parts move or rotate.
Apply recommended or equivalent grease to bearing and mating surfaces of all bevel gears, drive
gears, reset gears, wheel ratchets, ticket tray, shafts, studs, and bosses according to figures 4 and 5.
