Routine Maintenance
The overall maintenance of the Sharp MX-
3501N is very straightforward and simple.
Most users will find the directions easy to
use.
Refilling the toner extremely simple and
clean. The toner is located inside of the
front cover which opens down.
Once open, the four toner cartridges are
visible. Yellow, magenta, cyan, and black
span across the top from left to right. Each
cartridge is the same size and holds the
same amount of toner. The cartridges are
removed easily by lifting the colored tab
and gently pulling the cartridge straight
out. After removal, we noticed no mess
whatsoever. We could not create a spill
even after shaking and flipping the
cartridge.
The waste toner unit, a large black piece of
plastic, sits below the toner cartridges.
Users can remove it by pushing on the
green plastic button above it. The waste
toner unit opens down like the front cover
did. The tray is pulled out in a flat position.
The waste should be disposed of
immediately. The tray should be held flat to
reduce the chances of dropping lose toner
around the office. Although the process
was somewhat messy — it is after all a
toner waste unit — we were very pleased
with the cleanliness of the unit.
The drum units can be replaced when the
waste unit is out. While Sharp suggests
users place a service call to replace these
units, BERTL believes some advanced
users can replace them by removing a few
screws.
When paper jams occur, even novice
users would not have problems removing
jams from this machine. The larger touch
screen turns into an illustration which will
guide users through the paper removal.
The front cover is first released revealing the
toner cartridge supplies.
Toner cartridges can then be replaced. The
process is mess-free; BERTL analysts were
unable to create any toner spill even when
shaking the cartridge roughly.
The imaging drums, while supposedly an engineer
install process could be replaced by end users.
The bottom plate is lowered, three screws are
removed, then drums replaced easily.
