If the toner residual level is less than the specified value, DC controller notices two kinds of messages (toner absence notice, toner absence) to video controller.
The following is the relationship between the display message and the toner residual level.

2. Detection by toner refill quantity detection sensor
This detection sequence works out the quantity of remaining toner from the outputs of the toner refill quantity detection sensors (PS3 to 6) and displays the quantity
on the touch panel in units of 1%. The sequence is performed when power is turned ON, upon image formation (for each 1% of consumption), when toner has run
out (0% notification) or when the toner status changes from no toner to toner present.
When toner is absence, the printing operation of the main body is stopped.
The toner feed level per one block varies, so the toner residual information is just a target. When the toner residual becomes 1% or less, the residual information is
not displayed on the touch panel and 0% is displayed at the time of the toner absence.
When toner is absence, the printing operation of the main body is stopped.
The toner feed level per one block varies, so the toner residual information is just a target. When the toner residual becomes 1% or less, the residual information is
not displayed on the touch panel and 0% is displayed at the time of the toner absence.

The device does not have toner container detection.
Even if there is no toner container in the device, there will be residual toner in the refill screw, etc., so printing can continue for a few more sheets. If printing is
continued for just a few sheets, there should be no problem as regards image quality.
Then, the piezo-sensor that carries out the remaining toner quantity detection will detect toner out and will stop the print operation.

The transfer assembly is divided into the primary transfer block and the secondary transfer block.
The primary transfer block serves to move toner from the photosensitive drum to the ITB, while the secondary transfer block functions to move toner from the ITB
to print paper.
The transfer assembly consists of the following components: ITB cleaning unit, ITB, primary transfer roller, primary transfer roller, secondary toner inside roller,
tension roller, secondary transfer outside roller.
