Printer not printing in Colour

[mylogon]

Hi all,
I have a Lexmark PRO901 here which is refusing to print in colour. I have installed brand new colour cartridges which are definitely seated properly. The printer is reading that the cartridges were full when I put them in, and after I tried printing and photocopying a few things the levels have gone down, which I'm guessing is inaccurate considering not a single drop of colour is on the paper. I have updated the firmware to the latest version and that has done no good. I have tried printing from Windows 7 and Mac OSX for good measure, but, unsurprisingly it made no difference.
I've also tried cleaning the heads, aligning and every thing else I could see.
I'd really appreciate any help.
Thanks,
Luke

I wouldn't even reply, but I managed a printer service center a few years back so you might say, I've seen it all.  Well, almost.

Go into the control panel for that printer and make sure it's NOT set to text only or 'Black' only.
I'm not sure of the exact wording for a Lexmark printer.

If you had an Epson, I could be of more help.  Sorry.

fyi, It was a faulty printhead and after being on the phone to Lexmark for AGES they eventually sent out a new one, along with new cartridges for free. Not bad.

sorry for not getting back. just found this old topic.
