Pins
7, 8
The 3/8" (95 mm) wide pin 7 at the center-point of the cartridge mates
into a slot in a spring-loaded bushing in the carousel end panel. This
pin functions similarly to pin 2.
Pin 8 is the flex-type pin on the rear face of the cartridge. It mates into
a slot in the same bushing as pin 7 described above, but its function is
entirely different. A ramped opening into the slot actuates pin 8 and
unlocks the toner cartridge so that its inner workings rotate indepen-
dently of its outer housing. This design accomplishes two things: it
keeps toner plumb so as to avoid scattering that would otherwise occur;
and it reveals the developing cylinder in synch with a cartridge’s arrival
at the “stop” position.
Pin 9 The developing bias transfer pin on the carousel end panel presses
against the contact inside the rear face of the cartridge.
