Put in the new toner cartridge by
positioning it in the guide. Slide it gently
into the machine. Do not try to push or
lock the new toner cartridge in; it must
rest loosely in the guide rails and will
automatically be positioned properly
when the front cover is closed. Note that
each color cartridge is individually keyed
to prevent improper installation. Match
each cartridge color label to the same
color label on the machine.
