Dirt and/or stains on the
Rollers and Lenses
Clean the Transport Path. Refer to the “Cleaning Procedure” on page 2-11.
The Unit has been
disassembled, and calibration
adjustments have not
occurred following a
reassembly.
Calibrate the Sensors after reassembling the DBV-400 Unit.
The wrong Software version
or an older Software version
is being used.
Make sure that the programmed Software is the latest version, and it
supports the Currency values for the specific Country (e.g., check
denomination/issuing year).
