A. Unit mounting detection
• The TCR sensor board detects the mounting condition of the developing unit.
• When developing unit is detected in the mounted condition, control now proceeds to the
"new article detection control".
(1) Detection timing
• The unit mounting detection control is performed under any of the following conditions:
"The power switch is turned ON (with the front door and right door are closed)"
"The front door or right door is opened and closed with the power switch in ON position"
(2) Operation when it is detected that no units are mounted
• The message "Developing Unit Installation Error" appears on the control panel and the
machine prohibits initiation of any new print cycle.
• The message "Developing Unit Installation Error" disappears as soon as a developing
unit is mounted.
