How to use expired ink carteges in DesignJet T920 plotter?

[scania471]

Hello everyone!

I have a T920 plotter. Previously, I got many ink cartridges (2-3 packs)for it but nearly all of them expired by 2-3 days. I would like to use them because the ink levels are 90% or above. I don't want to throw it to the trash as they are so expensive in a one-person company. Is it possible somehow to overwrite the expiration date of the and continue using it?

I can send print jobs to the plotter but it doesn’t do anything. It has a yelow triangle at the bottom of all colors.

The data about ink level and expiration date are stored on the integrated circuit ( chip) that is on the ink cartridge. There is no option to bypass or overwrite data on the chip unless you remove the original chip buy and replace with aftermarket chip for each ink cartridge.

The reason why printer stops when ink cartridge expires is that in the expired ink cartridge chemicals in ink liquid may cause poor print quality and defect on printers printhead
