Slide 80
Transfer Current
First, a low current (10
μ
A) is supplied at the
leading edge (before the print area).
This prevents positively charged toner remaining
on the drum from transferring to the roller.
Then a high current is supplied to transfer the
image to the paper.
The amount depends on paper size and type.
(See the table on the next slide.)
This transfers the toner to the paper.
Finally, at the trailing edge, either:
Multi-copy mode, between pages: Low current is
applied again.
Final page: Transfer current is switched off.
No additional notes.
