6.15.4 DETECTION OF A NEW PCU

Before starting to use a new PCU, the machine must (a) agitate the toner/developer
mix, (b) initialize the TD sensor, and (c) initialize the PCU counter. This machine
automatically detects the presence of a new PCU and carries out these operations.

At time of copier installation

The first time the machine is turned on following installation, a factory-set flag
informs the machine that the PCU has not yet been initialized. The machine carries
out the necessary initialization automatically.

When a replacement PCU is installed

Replacement PCUs have a special mechanism that trips when they first start,
informing the machine that a new PCU has been installed. (Preinstalled PCUs do
not include this mechanism, and have two empty pins in their connector.)
