Aries-P1.5/C1.5
Reference
Developer tends to accumulate in the gap between the rollers and casings (indicated in
pink in the cross-section diagram below), and once accumulated, it cannot be easily
removed in the standard developer removal procedure, thus this additional procedure is
required.
The reason for tilting the unit as you remove old developer is due to the composition of the
3 augers as shown below. Developer stuck around the Development and Collection
augers is removed rather easily as these augers position under the toner supply port
whereas the Agitation auger does not. Tilting and shaking the unit helps the developer
stuck around the Agitation auger to fall towards the toner supply port.

This auger does not
position under the same line
as where the toner supply
port positions. This is why
the unit should be tilted to
allow loose developer to fall
in the direction indicated
with the red arrow towards
the toner supply port.

Because these 2 augers are located
under the same line as where the

developer stuck around these rollers
is removed rather easily.
