How is ink level determined?

    They, too, do not always hold treasure. :gig

    All kidding aside, excellent job on the Freedom Method video. Clear and concise.

    That method has now been superseded by the dribble method, because it’s easier for the Auld men to handle... :p :lol:

    Air in a Canon print head could be a problem. This is why each time you remove a cartridge and install it back the printer will invoke a cleaning cycle when you start up the next print job.

    If your printer is powered off and remains off for a prolonged period of time the printer will automatically invoke a cleaning cycle too. I had a power outage yesterday. When the power is restored and it received a new print job it did a cleaning like crazy before it started to print. It was for getting rid of possible air in the print head.

    What a resetter does to reset a chip is by writing into the chip with data that resembles empty. If the data is identical to what was in it by Canon then it does reset it to true empty. But if the data is only close to empty (to avoid a potential copyright issue) then it is only close to be empty.

    I think you probably overfilled your cart by 1 ml. It actually is a 1 ml insurance to make sure you don't run with a dry ink cartridge. Much better than 1 ml short.

    That makes little sense. It is more reasonable to set the chip to FULL. I base my assumption on the CPU instructions for a test for zero as a result of a decrement operation versus a comparison and then test for equality. It's an optimization thing.

    Why is it taught that cartridge chips are intelligent and can somehow communicate and have direct access to the printers’ memory, they can’t because its primary task is read only, the printer does all the reading and counting.

    The chip receives information from the printer only after the chip is shown to be registering as full, then stage drops occur to 3/4, and half full, all are only estimated ink levels and are not very accrete (guesstimate).

    Only when the prism declares a low ink level, does the printer determine accurately the amount of ink left that can be used up safely before it stops and all communications to the chip are declared unreadable and void, you can hold the Resume button in for 5 seconds to continue. ! !

    But running with ink monitoring disabled will cause the printer to deliberately use up excessive amounts of ink on cleaning cycles, and without diligent self-monitoring by the owner the printer will cause a fatal error to occur, this is better known as self-destruct mode...

    The use of a redsetter will prevent the early demise of your print head and waste pads, by bring the chip back to a useful state and allowing the printer to communicate with it once more and exiting the self-destruct mode...

    I seldom ran a printer with ink monitoring disabled (only for a very short time when I was busy printing), so I can't confirm the printer does more cleaning cycles.

    It is registered in the EEPROM.

    Does this occur on all Canon printers or has it only be observed on particular models ?
