ip4500 - how to disable low-ink warning...and other questions

[yanomilano]

I just did my first refill of one of .
Can I disable the low-ink warning?
Should I wait until the original cartridges run out?
Should I flush cartridges of the original ink or can I mix in the precision color ink?
Are they gonna drip?
What cartridge resetters do you recommend and where to get them?

Thanks!
