Questions about this item

When will the 250 ml black ink cartridge need replacing?

Replace the cartridge once the 250 ml of black dye-based ink is depleted; print volume determines the interval.

What limits continuous printing on the ColorMax7 or ColorMax8?

The 250 ml ink capacity is the limiting factor; the printer stops when the cartridge runs dry.

Does the cartridge generate extra heat or noise during all-day printing?

The ink cartridge itself adds no heat or noise; any sound or warmth comes from the printer mechanism.
