This is annoying: bad IP4300 print head. Replacement?

[The Hat]

Where'd this come from?

They have been at that for years, Canon print heads are designed to fire an X amount of ink and then cease, then give a bog standard fatal error message out of the blue, the older iP series print heads may not have had this restriction, maybe one of the reasons why they lasted so long.

Their calculations are based upon ink usage and not the number of sheets printed, Canon did changed most of their print head Code Numbers, I wonder WHY... ?

Here is a cleaner with a guarantee for Epson, Canon etc for a 'Perfect Print' - it's April now - o.k. - but I thought Fool's Day is over.....

No shit Sherlock...
Maybe this crowd might introduce us to cartridge refilling...

All I've seen is speculation so far.

I have to agree...

I can agree that Canon print heads have a design lifetime, probably based (loosely) on nozzle firing count, else they won't make it through the warranty period. I doubt that there's an actual "nozzle firing" register in the firmware that, when reached, initiates some sort of disabling function.

I had a QY6-0049 print head go belly up while running a print job, and with a message to replace the print head, which I did but a week later I reused the same old head again and it last another 3 months but then started to have a lot of different missing nozzles, (Miss-fires), the new head (QY6-0066) is still working today...

The printer “HEADS” back then would last 60 years...

Canon may not count nozzle activities or use it stop the printhead usage, but I know that Brother desktop models did a nozzle firing count in the firmware, probably for maintenance/warranty reasons e.g. excessive usage. And Epson is counting nozzle activities in the firmware as well on large format printers.

Anyone knowledgeable: My Pixma IP4300 printhead just died, but I still have lots of cartridges. There is a local offer of a IP4500 printhead, the thing looks very similar, only difference that I see is that the plastic base up front is somewhat shorter. Could I use that printhead in the IP4300, or wouldn't it work? Thanks for any idea! Anja
