How to Refill CANON 045, 045H, 046, 046H Cartridges 

If your cartridge is not an original CANON, it may look slightly different. If you bought a toner refill kit from us, please contact us directly for tech support at info@inkowl.com

Explain it properly

Yes, you will use the whole bottle. For Canon 045/045H, we supply 35g of black and 30g of color. For Canon 046/046H, we supply 60g of each color.

Yes, the procedure is the same for 054H

CANON color laser cartridges can typically be refilled 3-5 times while maintaining an acceptable print quality. However, it's not the act of refilling itself that degrades the cartridge, but rather the printing thousands and thousands of pages. If the print quality was still satisfactory before the cartridge went empty, you can refill it another time!

The refill kits are available at www.inkowl.com

You can print with the old chip as long as you want! You never need to change the chips on this printer

Technically there are ways to get the cartridge open without making a hole, but it requires complete disassembly and is generally reserved for refill shops and professional remanufacturers of cartridges. You can look for "remanufacturing" instructions. As our products are targeted towards users and not professional refill shops, the methods we recommend are always a compromise between quality and ease of use. In our opinion, any marginal gain in quality from fully disassembling and cleaning out the cartridge simply does not justify the vastly more complex procedure and increased risk of error.

The second hole is for the "excess toner" or "waste toner" compartment. This compartment gradually fills up with use, and eventually it will fill up completely and the cartridge will stop working. So, to avoid this, we do recommend emptying this compartment out with every refill.

inkowl.com Gotcha. Thanks

inkowl.com after you have refilled once, can you reuse the toner that comes out of the "waste" compartment?

@@angelawilson8062 You should never reuse waste toner. It's contaminated with dust and debris which you DON'T want to bring inside the toner feed mechanism.

to empty to old waste toner

For this model, we recommend 35 grams of black or 30 grams of color.

@@InkOwldotcom Thank you very much for your answer

Yes, this will work on that model!

Yes, this video also applies to the MF631cn which uses 045/045H cartridges.

No, there's no need to cover it or do anything, in fact, simply continue printing. The toner level won't be displayed, but the printer will print normally.

@@InkOwldotcom So basically we have to just wait until we start to see printouts start to fade before we will know its getting low.
