As reported I was able to reset the waste ink counter with service tool 5204.

https://www.printerknowledge.com/threads/maxify-ink-absorber-counter-reset.14065/#post-122349

I was deliberately running the magenta cart with an autoreset chip showing empty to see what happens and this morning I had error B504.

According to Canon this is due to the use of cartridges "not produced by Canon" but https://www.inkhub.com.au/ink/b504-error-canon-maxify-printers says this can happen with OEM's too

> The Canon B504 error code is a built in protection to stop the delicate resistors in the print-head from overheating and self destructing. The problem occurs when there is no ink flowing to the print-head to keep it cool, which can occur when a cartridge is run completely dry or no ink is flowing. <

This proves there is indeed an ink flow monitoring !

Canon suggests to restart the printer.
Strange enough this resetted the ARC but the error returned.

I unlocked the printhead by turning the wheels and changed the magenta cart (this is easier when you have removed the plastic cap on top that serves only to block you to change all the cartridges at once).

After a lot of whirring and shaking everything seems OK again.

Excellent find, palombian. Glad Canon is doing this. :thumbsup

I gather that the error occurred because the ARC chip reset to "new cartridge" on an empty cartridge and when the printer saw a "new" cartridge had been inserted it tried to do a new cartridge ink purge and no ink flowed. The printer was behaving as designed. :)

Most probably.
But this drives an inexperienced user mad, since he does not know how to change the cartridge.
There were reports on amazon.de from people who were told only Canon could do this.

We are lucky Canon uses rather simple tricks - in fact in the interest of the printer.

As reported before I am having ink feed problems with the cyan since long. I neglected this deliberately to see if this ink monitoring would jump in, but it never happened and at the end I had damaged nozzles.
I rinsed the printhead and changed to another ink for cyan.
The problem did not occur since and I can continue to use the printer for drafts and B/W (and tests ;) ).
The ink was from octopus-office.de, only the cyan, no problems at all with the other colours.
@Redbrickman informed me he had the same problem with the same ink.

Most probably I could have saved the printhead if I had rinsed it in time.
Learning money, not a drama after 25.000 sides printed.
The Maxify is very solid but there are limits.
