1. Drive. The shaft, Figure 4, on the bottom of
the printer is driven by a bevel gear from a
meter register or other equipment. The
printer's bevel gear and shaft assembly turns
in a counterclockwise direction. The internal
bevel gear on the shaft drives the clutch
assembly, associated pinions and the gear
assembly of the right-hand print wheel.
2. Printing. ln printing operation, a ticket is
inserted into the slot of the ticket tray until it
bottoms on the internal stop.
a. As the printing knob 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,
by means of the tray actuating cam and gear,
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 knob 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
its original position and the seal pin releases
the ticket.
SECTION 3. PRINTER REMOVAL AND
INSTALLATION
A. REMOVAL.
Before maintenance, remove the printer from
the meter register as follows:
1. Break the seal and remove four bolts on the
bottom corners of the meter register.
2. Remove the screw from the center of the
printer knob and remove knob, shaft extension
and washers from the printer. Remove the
cover.
3. Remove the bolts securing the printer frame
to the meter register. Remove the printer.
B. INSTALLATION.
After maintenance, install the printer onto the
meter register as follows:
1. If the meter register is still in the case,
remove the three screws holding it and lift the
register from the case. Reset the register to
zero by turning the small gear at the left end of
the reset shaft counterclockwise.
2. Install printer knob and shaft extension on
printer and turn it until tray is in the outward
position and seal pin down. Remove printer
knob and shaft extension.
3. Rotate the large idler gear (B) so that the
timing marks on it and the printer gear (A)
align. See Figure 6. It may be necessary to
hold the idler gear in position until the printer is
mounted and the idler gear and print gear
engage.
4. Mount the printer onto the meter register
and secure with bolts.
5. Check the position of the timing marks on
the printer gear (A), idler gear (B) and register
gear (C). They must be in the position shown
in Figure 6.
6. Loosen the printer bevel gear set screw and
adjust for proper backlash between the printer
bevel gear and the meter register drive gear as
necessary (Figure 20).
7. Place assembly in register case and secure
with three screws.
8. install printer cover using four corner bolts
under the register.
9. install the large steel washer, then the
rubber washer on the slotted end of the shaft
extension.
10. lnsert shaft extension with washers through
hole in cover and engage the end of reset
shaft.
11. Position reset knob with arrow pointing up,
approximately vertical, on spline of shaft
extension and secure to printer with the 2¼
