Theory of Operation
Imaging Unit Life
A counter tracks the number of prints since the last detection of a new
Imaging Unit. As this count nears its maximum value, the system generates a
warning message. When the count reaches the maximum value, a
replacement error is generated. The counter is reset following the detection of
a new Imaging Unit.
The system checks for a new Imaging Unit when the Power Switch is turned
On or the front door is closed. If a new Imaging Unit is detected, the image
stabilization sequence is carried out.
The life counter is reset when a new DC is detected. When a predetermined
number of printed pages are produced after the life value has been reached,
the machine displays a DC replacement message.
Toner Cartridge
The system employs four Toner Cartridges (CMYK) installed in a revolving
Toner Cartridge Rack that positions each cartridge’s developer roller over the
Drum. A cross section of the Toner Cartridge showing functional components
appears below.
1.
Toner stored in the hopper is agitated by the agitating blade and conveyed
into the toner supply portion by the conveyance blade fitted to the leading
edge of the agitating blade.
2.
Toner in the toner supply portion is conveyed by the supply roller onto the
developing roller.
3.
At this time, the 1st and 2nd regulator blades moderate the height of toner
on the surface of the developer roller.
4.
When positioned by the Toner Cartridge Rack in the developing position,
toner adheres to the latent image on the drum. Toner left on the surface of
the developer roller following transfer to the drum is returned to the toner
supply portion.
To attract toner to the drum, a developing bias voltage (Vb) that includes
both DC (-) and + AC components is applied to the developing roller
during development. The AC component is applied only during
