Waste Toner Near-Full/Full detection control
A. Waste toner near-full detection control
• An optical sensor is used to detect waste toner. When the sensor is blocked for a given
period of time, the machine determines that the Waste Toner box is nearly full of waste
toner.
• At this time, a corresponding warning (near-full warning) is given on the control panel.
B. Waste toner full detection control
• Upon the waste toner near full detection, the counter exclusive for waste toner inside the
machine starts counting. When the number of color pages reaches around 3,000 sheets
(A4) or the number of monochrome pages reaches around 12,000 sheets (A4), the
machine detects a waste toner full condition and stops printing.
• Counting method of the counter exclusive for the waste toner is corrected to count the
value appropriately according to the color or monochrome mode or paper length.
• When the waste toner full counter reads 12,000, the machine regards that the waste
toner box is full.
