The Rex-Rotary 6640 Fax is refilled with the "Unscrew, Unplug and Pour" fill method

Square These are general instructions for this fill method. We supply specific instructions for the majority of printers with the toner. This is a straightforward and quick way to refill.

First of all prepare your worksurface. Working in an area of subdued light, cover your work surface with some newspaper. You may choose to wear latex gloves or use a dust mask. Take care not to touch or damage the imaging drum on the bottom of the Rex-Rotary 6640 Fax toner cartridge. Greasy marks or nicks in the surface will ruin the print quality.

FIller cap

The filler cap is hidden under the removable end panel. Unscrew the end panel from the side of the cartridge. Put the screws somewhere safe. Remove the end panel. Locate and remove the round plastic plug on the side of the Rex-Rotary 6640 Fax toner cartridge with pliers or a flathead screwdriver. Carefully avoid damaging the plastic around the edge of the hole. Push the flathead screwdriver under the lip of the filler cap and lever it upward. Work around the edge of the filler cap until it pops out.


Pour slowly into the toner chamber and be careful not to squeeze the bottle hard.

Leave an air space at the top. We may supply more or less toner in the bottle than your cartridge can contain. Do not overfill. Ensure that there is at least 5cm of space above the toner with the cartridge upright on its end.

Wipe any loose toner off the outside round the hole with a duster and then close the hole with the filler cap so that it does not leak. You may like to test the seal by holding the cartridge above a sheet of white paper and gently shaking it. If some toner leaks, stick brown vinyl packaging tape around the edge of the filler cap. Replace the end panel and screws.

See the instructions provided for emptying the waste toner. The waste toner can build up and permanently damage the toner cartridge during the first refill. Emptying it each time you refill ensures that the toner cartridge lasts for the maximum number of refills (typically three).

Replace the cartridge into its lightproof plastic bag. Clean away any spilt toner and you are done!

Note that you have done nothing to disturb the cartridge so if it had packed up because it had run out of toner you should have it back in action without affecting any components.

We suggest you always have at least one spare refilled cartridge ready to be used in your machine as you do not want to have to refill a cartridge in the middle of a print run.

We also suggest that you always have one spare new OEM or remanufactured cartridge as well. Your refilled ones will go on beyond their first life and will save you money.......but they will not go on for ever! Sooner or later something will deteriorate inside and you will need to start another one.

Killer Chips

You have probably got the idea now that the manufacturers are doing their best to protect their large toner cartridge profits from people like you who want to refill their own cartridges and from the remanufacturers who offer a better priced replacement. In recent years they have added electronic chips to some cartridges which monitor how much toner is left. It would be fine if that was all they did but some of them also close down the machine when it goes low....... and refilling it won't reverse that. So for some machines you need to screw or plug in a new chip before your refilled cartridge will work. We either supply the chip with the toner where it is always needed or else, where one chip lasts for several refills, we draw your attention to it so you can buy it separately.
