Functional Description - Aristocrat USA MAV500/MKVI Service Manual

Ticket Printer
Figure 17-3 shows the paper path through the feed rollers. The two plies of paper
must follow their correct paths to ensure correct operation and that the journal copy is
not cut off with the original and deposited into the coin tray.
Ribbon Cassette:
The average life expectancy of a ribbon cassette is 1.5 million characters. The ribbon
cassette should be replaced when the printouts become unclear. The printer will not
function if a ribbon cassette is not installed.
Take-up Unit:
The take-up unit is mounted on top of the chassis. It provides a motor driven shaft for
the journal paper to spool onto, as well as a shaft for mounting the two-ply paper roll.

17.1.2 Functional Description

Depending on the machine software configuration, the printer can provide the
following:
A ticket showing the customer's winnings (which would usually be redeemable
•
from the cashier).
A printout of audit information.
•
A printout of machine security events such as:
•
Main door opening,
•
Logic cage door opening,
•
Cash box door opening,
•
Mechanical meter accesses
•
Resetting of the electronic meters - both before and after the reset.
•
The printer module receives data, control signals, and 24 V DC power from the
machine via the 20-way Minifit Junior connector P7 on the Backplane.
Movement of the print head (left to right and right to left) is provided by a
mechanical drive shaft on which the print head is mounted. The drive shaft is driven
by the electric motor and gear train. The drive motor mechanism includes an encoder
gear and sensor which derives timing pulses from the motor. The electronic
controller PCB uses the timing pulses to determine the exact position of the print
head along the drive shaft.
