Section 4 –Maintenance
: DISCCONECT ALL ELECTRICAL POWER TO THE MACHINE BEFORE SERVICING.
4.1 –Bill Validator Maintenance
The Trilogy Series note acceptor is relatively maintenance free. An occasional cleaning is all that is
needed to keep the acceptor in top operation. To clean the acceptor:
Remove power from the machine.
Unplug the I/O connector and/or power connector from the side of the acceptor.
Remove the Lower Transport by pushing in the latch located on the bottom of the acceptor at
the rear. Gently pull the Lower Transport out of the assembly.
Clean the note path using a soft cloth or towel. Do not use any cleaners other than a 50/50
mixture of water and isopropyl alcohol.
NOTE: Pay particular attention to the gray oval pieces of plastic in the lower and upper transport area
and the Optical Anti-stringing (OAS) sensors located in the lower transport plate (on each inside edge
of the plate). They all must be cleaned well for proper operation.
Do not use any oils or silicon spray on the acceptor!
