Where is the serial number of the NP Series Printer located?
On all printers, the serial number can be found on the back of the unit. It is printed on a white label below the model number. Serial numbers are nine (9) digits and follow the form S/N 40CxxxxB, 30CxxxxB, 44CxxxxxB, 36CxxxxB, etc. On newer units, the serial number can also be found on the inside right side of the chassis. Open the door and look on the right wall. The S/N will be located above a barcode.
