Detects paper jams at the paper exit if the paper does not arrive
or leave the machine at the prescribed time.
Detects when the Copy Paper Tray B75 is full and temporarily
pauses printing so the operator can remove the stack from the
tray and continue.
Monitors the amount of toner in the developer/toner mixture
in the development unit of the Magenta PCU.
Monitors the amount of toner in the developer/toner mixture
in the development unit of the Black PCU.
The temperature and humidity readings of this sensor are
referenced to a lookup table stored in the ROM to 1) Correct
the charge roller voltage , and 2) Set the length of time the
agitators in the development unit rotate to mix the toner and
developer.
Monitors the amount of toner in the developer/toner mixture
in the development unit of the Yellow PCU.
Monitors the amount of toner in the developer/toner mixture
in the development unit of the Cyan PCU.
Switches the ITB lift motor off when the ITB contacts the drum
of the K_PCU
Pulls and pushes the pressure roller to separate it from and push
it against the hot roller. The pressure roller is a soft sponge roller
that would warp out of shape if it were allowed to press against
the hot roller while the machine is idle.
Reads the potential sensor pattern from the surface of the drum
in the black PCU.
Reads the potential sensor pattern from the surface of the drum
in the magenta PCU.
Reads the potential sensor pattern from the surface of the drum
in the cyan PCU.
Reads the potential sensor pattern from the surface of the drum
in the yellow PCU.
