(2) Waste toner full condition
• When a waste toner near-full condition is detected, the "waste toner full detection counter" is incremented according to the image density
information of the print image during each of subsequent print jobs.
• When the waste toner full detection counter reaches a threshold value, the machine determines that there is a waste toner full condition.
(a) Execution timing
The waste toner box full detection control is performed under any of the following conditions:
• "The machine determines that the waste toner box is mounted in place using the waste toner box set sensor."
• "The waste toner full sensor detects a waste toner near-full condition."
• "During a print cycle"
• "During execution of image stabilization control"
9.3.5 Waste toner box new article detection
• The waste toner box is not provided with any new article detection mechanism. Detection made by the waste toner full sensor is used for
detecting a new waste toner box.
• When the waste toner full display appears, the existing waste toner box is replaced with a new one. When the waste toner full sensor
remains unblocked for a predetermined period of time or more, the machine determines that the normal state is recovered (the old waste
toner box is replaced with a new one).
• Determining that a new waste toner box has been mounted, the machine resets the waste toner full display, allowing the initiation of a new
print cycle.
(1) Timing at which to reset the waste toner full display
The waste toner box full detection control is performed under any of the following conditions:
• "The waste toner full sensor detects a waste toner full condition."
• "The power switch is turned ON"
• "The front door is closed"
9.3.6 Waste toner spillage prevention shutter
• The toner collecting port for the transfer belt unit is provided with a waste toner spillage prevention shutter that prevents waste toner that is
transported from the transfer belt from spilling during removal or reinstallation of the waste toner box.
• Inserting the waste toner box into its mounting position pushes the shutter at toner collecting port of the waste toner box, thus opening the
toner collecting port.
• Removing the waste toner box allows the shutter spring to close the shutter at the toner collecting port.
