Notes
◆Until you are ready to install the Process cartridge, do not
unpack it and store it in its cardboard container.
◆Firmly hold the handles on both sides with both hands when
handling the Process cartridge.
◆Take care not to scratch the surface of the photoconductor
drum during handling.
◆With the exception of the handle area, take care to avoid
contacting the surface of the photoconductor drum as much
as possible.
◆Except when you install the Process cartridge into the device
body, keep the cover on the Process cartridge cover to
protect the photoconductor drum and to prevent optical
deterioration.
◆Some black developing toner may be visible on the
photoconductor drum of a new Process cartridge. This is to
ensure that the cartridge is kept in a ready-to-use condition
at all times, so you may use it as it is. After the cartridge is
mounted on the device body, cleaning will automatically start
so you need not worry about the liquid affecting printing
quality.
◆Since waste toner remains in the used Process cartridge,
take care not to shake it strongly, tilt it sharply, or hit it with
force as this may cause waste toner to spill out.
