These instructions cover the recharging of the Minolta SP-4X toner cartridge used in the Sharp UX-3200, UX-3500, and other
printer/fax machines using the Minolta SP-4X Laser Engine. Although these cartridges appear very similar to the Minolta SP-6,
there are some differences. The SP-4X cartridges are held together with plastic tabs, and the toner is different from the SP-6.
SP-6 toner will produce light print and shading.
The SP-4X engine is a 4ppm printer engine that runs at 300 dpi. The toner cartridge is rated for 4500 pages at 5% coverage.
More than 200g will fit into the Toner Supply housing, but the waste chamber will fill up and leak if this is done. The Drum-101
will work in this cartridge, the gears must be transferred from the old drum to the new.
This cartridge also uses a charge felt to charge the OPC Drum. Instead of using a Corona Wire or rubber Charge Roller, it uses
what is considered to be a conductive felt strip. So far it seems to be good for at least a few cycles.
The purpose of this disassembly procedure is to vacuum out toner that will have spilled inside the cartridge during shipping and/
or rough handling, to clean the debris cavity, and to clean and fill the supply chamber with new toner. This disassembly
procedure should also be used to examine the internal parts of the cartridge for possible damage, or wear should the printing of
the cartridge be poor and not correctable by any other means.
The following procedure should be read entirely before proceeding.
