[8] 1st image transfer
• It is the access system to scan the printed data from the PC to the printer.
This model supports the ethernet as standard.
• Printed data in page description language are converted to VIDEO signals
(C, M, Y, and Bk) to output to the printer's image processing section.
• D/A conversion will be performed after the VIDEO signals (Y, M, C, Bk) are
corrected. This data will control the emission of the laser diode.
• The image of the original projected onto the surface of the PC drum is
changed to a corresponding electrostatic latent image.
• Supply DC ( - ) charge on the PC drum.
• Expose photo conductor to a laser beam to develop electrostatic latent
image.
• The toner, agitated and negatively charged in the developer mixing cham-
ber, is attracted onto the electrostatic latent image formed on the surface of
the PC drum. It is thereby changed to a visible, developed image.
• AC and DC negative bias voltages are applied to the developing roller,
thereby preventing toner from sticking to the background image portion.
• A DC positive voltage is applied to the backside of the transfer belt,
thereby allowing the visible, developed image on the surface of each of
the PC drums (Y, M, C, and K) to be transferred onto the transfer belt.
• A DC positive voltage is applied to the backside of the paper, thereby
allowing the visible, developed image on the surface of the transfer belt to
be transferred onto the paper.
