USA MAV500/MKVI Service Manual
Bill Acceptor
With prolonged use, a build-up of dirt from the surface of the bills will accumulate on
the pressure rollers; drive belt surfaces and bill acceptor optics. These areas should
be cleaned to ensure reliable operation.
The procedure to clean rollers, belt surfaces, and validation optics is as follows:
1.
Remove the bill acceptor as described above.
2.
Open the upper guide to gain complete access to the bill channel.
3.
Using a soft lint cloth dampened with 90% isopropyl alcohol, wipe the bill
channel surfaces on both the upper and lower guides to remove any surface dirt.
Pay particular attention to the optics area and the magnetic head when
removing deposits from the surfaces.
4.
On the upper guide assembly, clean the surface of the pressure rollers. The belt
surface may be cleaned by using a thumb to rotate one of the drive rollers while
holding the cleaning cloth against the surface of the belt. Again, care should be
taken to prevent excess liquid from reaching the bill acceptor internals.

The following guide provides possible solutions to faults that may be encountered
