Pixma Pro 100 -- Printing grayscale when color carts are low

[eliu]

Hi, 

I'm trying to print a black and white document (I checked the black and white box when printing) but the printer is not letting me print it. Got four amber light flashes; checked and some of the color carts are low.

Is it not possible to print in black and white if some carts are low? Is there a way to circumvent this? I need to have this document printed ASAP and won't be able to get replacement color carts in time.

Thanks in advance

The Pro-100 will use color inks even when trying to print monochrome.

Ack that's a bummer. I'd read in a different thread that printing in grayscale wouldn't use colors. Thanks for the reply.
