Please read this instruction carefully before you start refilling.
When refilling toner cartridges we generally recommend our customers to wear latex gloves and a fine particle mask.
Take the cartridge and loosen the 3 screws marked in picture 1 with a screwdriver. Afterwards you need to undo two clasps (picture 2 and 3). Use a small plain screwdriver to do that. Now you can remove the side cover and the closing plug appears (picture 4).
Before refilling the toner cartridge, you should pour out the rest of the toner powder or exhaust it with an aspirator for toner powders. Otherwise the physical and chemical characteristics of the old and the new toner powders could lead to a formation of clots.
Take the toner bottle and screw the funnel on. It makes refilling easier. Now fill in the toner powder into the cartridge. Now you can seal the filler opening with the recently removed closing plug.
As the cartridge is equipped with a chip that monitors the filling level you need to change that chip after refilling the cartridge. As the chip is located beneath a cover you need to remove that first. For that remove the welding spots marked in picture 5 with a cutter knife or a plain screwdriver. Now you can remove the cover (picture 6) and exchange the chip. Now put the cover back on and fix it if necessary with a little hot glue.
By changing the chip your printer recognises the cartridge as refilled. Please refill toner powder every time so that the cartridge gets the entire page capacity. If you do it without refilling toner the printer recognises the cartridge as empty and the chip gets blocked. By this the chip gets useless. A chip can be used exactly one time. Your toner cartridge is now refilled and you can reinsert it into your printer.
Refill toner and toner powder may cause serious health problems if not handled carefully. We recommend always using breathing protection or suction chambers while filling toner cartridges. Furthermore, toner powder and refill toner can be highly flammable with an appropriate oxygen mixture. Please note as well, that you should touch the photoconductor drum in no case or expose it to direct sunlight. This could lead to faulty print-outs. Octopus Office will not take any responsibility for success or failure of the described procedure.
