* If the error [E010] caused by a paper jam underneath the drum cleaner often occurs due
to an insufficient paper separation from the photoconductive drum, set a smaller value in
the code 08-841, and see what happens. At this time, however, pay attention to the
transferability at the leading edge of the paper since this transferability can be slightly
narrowed depending on the environments and conditions under which the equipment is
placed or the media type of the paper used. (Refer to 3.6.1 in this manual about the
details of the code 08-841.)
