ok how do they know when they are empty (page counts, ink level etc.)

if you refill a cartridge and it doesn't get filled to what the manufacturer considers "full" wouldn't this effect the sensor? I just had a cartridge act like it was empty (cleaning and priming didn't solve the banding) - and this was a cartridge I had filled from before. I injected ink and the printing was fine. I can't say how many CCs got into it but I did 2 injections. Perhaps 10-20 pages got printed and suddenly to low ink indicator is flashing (Epson 440 for those who care). I don't know if this is accurate or whatever ...

Some of the newer ink cartridges have a memory of usage to disallow refilling. I guess they're getting tired of people not buying new ones. :)

Try taking out the cartridge and turning off the printer. Put the cartridge back and and turn on the printer and see if that works.

I don’t think the Epson 440 stops printing when the chip says it is empty like newer models, but it still tracks usage to determine ink level. HP tracks usage as well. Some of the newer Canons actually measure ink levels.

I had one HP that showed empty for a year because I refilled the same black cartridge. There is a trick with HP to reset the ink level but I haven’t read of one with Epsons unless KeithKman’s trick works. Get back if it does.
