7. Toner End Detection
The CPU uses the image density sensor to detect a toner end condition. The toner
end condition is reset by opening the front cover for more than five seconds. If Vsp
becomes greater than 0.8 volt twice, the CPU starts blinking the Add Toner indicator.
After the indicator starts blinking, the operator can make up to 50 copies, then
copying is disabled.
CAUTION: This copier detects the toner end condition not by a mechanical
system but by a software system. If the main switch is turned off
or the front cover is opened for more 5 seconds without
replenishing toner, it will require another 61 copies for another
toner end condition to stop the machine.
If a customer continues in this way, the drum and other parts will
be damaged.
