Clean the Transport path and remove any foreign object
discovered.
The Acceptor Unit is not
properly seated all the way
into the frame
(the Acceptor Unit latch
release levers are not locked
onto the frame).
Re-seat the Acceptor Unit back into the frame so it is firmly
seated all the way back into the frame so the Acceptor Unit
release lever latches securely lock onto the frame.
Bill is wider than 85 mm or
narrower than 62mm (out of
UBA Bill width
specifications).
Use only bills widths having the correct UBA size
specifications.

Dirt and/or stains on the
rollers, belts and lenses.
Clean the Transport path. Refer to the Cleaning/
Preventive Maintenance procedure in Section 2 of this Manual.
The unit has been dis-
