Refill Canon Pixma CLI-8 und PGI-5-Cartridges: A cartrige´s lifetime
What happens, if you do your refill more than once? We did it five times to check that out.
The sponges of the original cartridges proved to stay very elastic, after five refills the cartridges still didn´t leak.
There was no significant change in capacity of the sponges between first and fifth refill.
