The quality of the Canon LBP-810 is very good. It's a very old printer, without any chip.
Here is how you can refill this toner EP-22 Cartridge.
Do not drill, just glue a hole on top
I used an old simple solder iron.
Smooth the hole.
Make sure no parts get inside - if, remove it with tweezers.
Step 2: Refill
Just refill. I had an other old printer with lot of ink in it, so I just reused this ink.
I just used reinforced tape. And I used a regular paper to cover the hole.
That's it! Just leave a comment below.
You can also use the original filling hole, but then you need to unscrew one side.
There are 2 (two) parts holding together with two pins and one screw.
Just make sure, that the pins don't fall in the containment inside the toner cartridge! Just push it in with a screwdriver of a smaller pin until you can loosen the other part. If you do it so, the pin will stay within the hole. Later on you can take them out, and reuse them.
