Transfer Roller:
The black/gray sponge like roller which runs the width of the paper path
and is positioned just below the toner cartridge. During the printing
process, this roller is electrically charged and as the paper passes
between this roller and the drum in the toner cartridge, the toner
from the drum is transferred to the paper. It is subject to mechanical
wear and degradation of it's ability to hold a uniform charge. It also
accumulates paper dust and can be contaminated with finger oils if
touched.
Fuser
Assembly:
This is the assembly which uses heat and pressure to "fuse" or
melt the toner into the fibers of the paper or media. Because of the heat
and pressure this assembly is subject to mechanical wear. The heating element
is also subject to electrical failure. Plastic gears can degrade over time
and continuous exposure to the high temperatures and eventually fail.
Installation of a maintenance
kit involves replacement of the parts listed above and any needed cleanup
of toner and paper dust as well as inspection of other high wear items.
These kits are designed to be user replaceable, and many users choose to
replace their own maintenance
kits and save the expense of a service call. We offer maintenance
kits for Hewlett Packard and Lexmark printers with installation instructions.
Exchange kits contain a remanufactured fuser assembly, transfer
roller, pickup rollers, separation pad and parts needed to perform
the printer maintenance function on the selected printer. On exchange
kits, the fuser assembly must be returned within 15 days to avoid
being charged for the core. Our kits include a pre paid return label.
* Interval is the number of pages between installation
of the maintenance kit parts. This is based on the manufacturers
recommendation. On some machines, a message appears on the display
to indicate that maintenance is required. You can continue to use
the printer, but for optimum performance it is recommenced that
the maintenance kit be installed. Once the maintenance kit is installed
you can reset the display message with the instructions included.
On printers with intervals marked N/A, the manufacturer does not
provide a recommended page count between maintenance kits.
