Toner Bank Unit; Cleaning Unit - Gestetner A294 Service Manual

1.4 TONER BANK UNIT

1. The toner bottle gear has been
modified so that it is not possible to set
the existing toner bottle. Only the new
bottle can be set.
2. To ensure that toner clumps or
blockage do not occur in the toner
bank unit, mylars [A] have been added
to the toner agitator.

1.5 CLEANING UNIT

1. Insulating layers added
To ensure that small white spots do
not occur, which can result from the
affect of the heat from the fusing unit
on the cleaning unit, insulating layers
[A] have been added.
2. Cleaning brush modification
To ensure that Medaka images (black
spots) do not occur, the cleaning
brush [B] has been changed to a
looped fiber type, increasing the
efficiency of brush.
3. Magnet added
To ensure that carrier is not attracted
to the drum, a magnet [C] has been
added to the cleaning unit. This will
attract the carrier particles toward the
unit instead.
The magnet can be removed to clean
if necessary. (The recommended
interval to check and clean is every
300K prints.)
4. Shape change in transfer unit
entrance stay
To minimize toner and other particles
on the drum surface, the gap between
the drum and stay has been increased.
