I have an epson cx3600 colour inkjet printer. I never print colour. The colour cartridges are now all flagging low so can I replace them with all black cartridges, ie have 4 black cartridges in one printer, or will this damage the printer in any way?

I have set the printer software to black only printing, but over a long time the colour cartrdiges are all low.

do the black cartridges even fit the colors' bed?

Well spotted sir, they do not.

I hate the fact that even though I never use colour printing and my driver is set to "black ink only", I still end up replacing the bloody things over time. I think every time theres a power failure or the printer gets switched off by someone by mistake, when it starts up again it seems to do a head clean or use up ink doing something, and over time this uses colour ink even though I dont

Thanks for the reply
