Getting Fingers Dirty
These are the new HP ink jet cartridges. Has anyone tried refilling these yet? I have one here in the workshop and just cut it open to get a better look at the workings of the cartridge. They seem to have a bladder in them, But not sure why because the bladder doesnt seem to hold any ink. There is a single hole with a spring and small rubber ball on the inside that seals against the hole so it doent leak when the cartridge is out of the printer. Only thing im not sure about is the chip. The cartridge has an Expiry data like the older 920 cartridges but not sure if you can put them back in after they are empty.
