Since the new pigment based firmware is written to the flash
ROM by this upgrade service implementation, the display in the
sensor adjustment mode’s LCD display is as shown below. The
meaning of each value is as shown below.
• Panel Display: “Sen: Sensor Name A D ttt vvv”
• ttt = Difference between the sensing level when there is no
paper and when there is paper. This numerical value is
shown in Hexadecimal and changes depending on the
printer’s state.
• vvv = Sensor detection level when there is paper. The
hexadecimal number during the adjustment changes
depending on the VR element’s adjustment level and
the printer’s state.
