Thanks for the info on the date. One cartridge I have showed a date of
2001, several years before I acquired the printer!

Received mine a few days ago, along with a nice set of filled carts. All
I need now is an accurate scale and I'll be set.

ink levels. With a proper scale, and resetting the chips, I'll be
relying on weight rather than the "guess" that the chip reads out.
