Theory of Operation
8. Cleaning: The IDT2 cleaner consists of a conductive roller brush rotating
in contact with IDT2 after the point where the toner is transferred to the
print media. The cleaner receives a high positive voltage from the HVPS
allowing it to electrically attract any toner particles remaining on IDT2.
Toner remaining on IDT 2 after the image transfer to the print media is
temporarily stored in the IDT2 cleaner.
9. Static Elimination: The positive charge on the print media can cause
image quality problems by scattering toner. To prevent this, negative DC
voltage from the HVPS is applied to the back side of the print media by
the Detack Saw, located on the Transfer Roller. This negative charge
neutralizes and eliminates the static charge on the print media resulting
from the tertiary transfer.
10. Fixing: The initial image is unstable and easily smeared. To fix the image,
the print media goes through the Fuser where it passes between a
pressure belt and the heat roller. The toner is fused onto the print media
by the combination of heat and pressure.
11. Cleaning: During the general cleaning process, the voltage applied to the
IDT rollers and drums go through a cycle of changes to move the negative
and positive charged toner particles from the cleaners and IDTs and then
the Transfer Roller. The toner stored in the IDT1 cleaner, the IDT 2
cleaner is removed and deposited into the Imaging Unit waste toner
reservoir. Toner from the Transfer Roller, charge roller and refresher is
also removed and deposited into the Transfer Roller waste toner reservoir.
In each case the voltage at the point of attraction is set high and the
voltage at the point of disposal is set to 0V with the result that the toner is
moved to the high potential until at last it is deposited on the Transfer
Roller. Toner is removed from the Transfer Roller by the attached cleaning
blade and deposited in the attached waste toner reservoir.
