Expired ink, HP Designjet Z2100 / Z 3100

According to HP's webpages, the expired ink message can be overridden for some of their printers, including my Z2100 44". But, they have no info about this, anywhere, and HP Support in my country couldn't help in other ways than "Sorry, you have to buy new cartridge". But, I found a solution that wil let me use the remaining 13 unopened, original cartridges I have. And, now I know where to get all I need to save a lot on ink. Fantastic printer, lousy ink policy.

It’s best to think ahead from as early as possible when preparing these tactics of course– it can be a real nightmare to pick apart a model and add support structures or cut it apart.

@ThePrinthead Pick apart a model..? I'm just picking apart the inktank... "Add support structures"? What structures?

Macro Enter also has replacement bottoms that reset without tool, you cut off the bottom of the cartridge plastics and glue on a new one that has an auto reset chip in it. Each time you unplug the cartridge and reinstall it resets to full - great for allowing refills. About $5 a cartridge that way. The tool you show doesn't reset the HP factory chips so you have to rechip the cartridges anyway
