That is what we do - converting the small sponges of HP 123 305 650 652 etc. to XXL sponges - see below!
The original sponge of the HP 123 and HP 305 black is even smaller – they contain only 2ml of ink!
We modify the inside and place an XXL sponge with 12ml – 6 x more ink. For color its similar!
ink-jet reset chips - we can put them - but stopped, because its not necessary - it would make our refill only more expensive
What this means is this: we are working on equipping most of our refilled INK CARTRIDGES WITH RESET CHIPS. – to make them more user friendly.
Something we have been doing for years with our toner cartridges we are now going to introduce for refilled ink cartridges.
The reason we delayed with this for so long is that – for ink cartridges – it is a much more complicated workstep. But we have tested it and established the necessary equipment and know how to do it.
This means our refilled cartridges – e.g. Canon 445 446 / XL, HP 305 123 650 953 will very shortly work basically exactly like original cartridges.
When installing them they will show a full ink level.
