NOTE: 1) Improper cleaning can cause vertical white or black lines.
2) Failure to change the filter could cause complete clogging in the flow of the toner.
3) Failure to replace the cleaning blade could cause toner to cling to the transfer belt, dirty back sides
of copies, poor paper separation, or pawl marks on paper.
4) Failure to replace this item could cause the machine to return SC300, SC301, SC303, or SC304 due
to a corona housing leak.
5) Failure to replace worn pawls could cause them to wear and sharpen, thus increasing the chance of
scouring the drum surface.
