Sensors are expensive. Counters are cheap. Put in ink by weight. Assume pages at 60th percentile use of each color. Set counter. At zero, whine for more ink.

- mjevans 9y agoCounters are cheep; they /could/ count the actual requested ink coverage (in actual volume of ink product) across the lifetime of a cartridge. That would at least give a better estimate and you'd only need to update the batch counter a couple min after a print job (just in case there's another one). That would allow for a great reduction in programmable memory write cycles. Careful programming would also allow the use of a ring buffer that 'loops' with an erase the ROM page to vastly reduce the write count per cell.
- sliken 9y agoWhining would be fine. The evil part is completely disabling a cartridge because of a color you aren't using is low, or that the cartridge is arbitrarily too old. If you pay for ink you should be able to use it.
