New Unit Detection
There are two types of fusing unit: one for emergency maintenance (EM) and another for periodical replacement. The
fusing unit for periodical replacement has a new unit detection mechanism.
When the machine is switched on after installing a new fusing unit, the engine board detects the fuse [A] under the
drawer connector of the new fusing unit, and then blows the fuse. This resets the counter.
