Transfer Current
 First, a low current (10 μA) is supplied at leading
edge (before print area).
 Prevents positively charged toner remaining on
drum from transferring to roller.
 Then high current is supplied (amount depends
on paper size and type).
 This transfers toner to paper.
 Finally, at trailing edge, either:
 Multi-copy mode, between pages
» Low current is applied again.
 Final page
» Transfer current is switched off.
