• Shows the IDC bare surface output reading taken last (in 0.01 V
increments).
• It should normally be around 4.3 V.
• The output range is 0 V to 9.99 V.
• "Reading taken last" means: Latest toner density
• Relevant Components: IDC Sensor, Transfer Belt Unit
• Shows the T/C ratio (in 0.01 % increments).
• Standard value: 8 ± 2 %
• Relevant Components: PH Unit, TCR Sensor K
• Shows the T/C ratio (in 0.01 % increments).
• Standard value: 7 ± 2 %
• Relevant Components: PH Unit, TCR Sensor K
• Shows the grid voltage value of each color of toner when an
image is produced.
• Standard values: Around 500 V
• A correction is made to make the image lighter when the numeric
value is greater.
• A correction is made to make the image darker when the numeric
value is smaller.
• Relevant Components: Imaging Unit, High Voltage Unit (Develop-
ing Bias)
• Shows the developing bias value of each color of toner when an
image is produced.
• Standard values: Around 400 V
• A correction is made to make the image lighter when the numeric
value is greater.
• A correction is made to make the image darker when the numeric
value is smaller.
• Relevant Components: Imaging Unit, High Voltage Unit (Develop-
ing Bias)
• Shows the IDC intensity adjustment value.
• It should normally be around 40 and can range from 0 to 255.
• The value becomes greater as the Transfer Belt Unit has been
used more.
• Relevant Components: IDC Sensor, Transfer Belt Unit
• Displays the Grid voltage value of each color when printing the
image on the thick paper.
• Standard values: Around 500 V
• A correction is made to make the image lighter when the numeric
value is greater.
• A correction is made to make the image darker when the numeric
value is smaller.
• Relevant Components: Imaging Unit, High Voltage Unit (Develop-
ing Bias)
