What does "recommend new C-CRT" mean on the Cannon Pixma MX310 message display?

[pdott74]

I have a pixma all in one printer.  Yesterday I sent a fax with no problems.  Later in the day I tried to send the same fax to another number but it wouldnt send.  I get a message in the display window that says "Recommend new C-CRT". 

I don't have a clue what that means.

Can you help?

Thanks Phyllis Dottery

I think it means cyan cartridge...you may be out of ink.

Hello.

This error indicates that the color cartridge is empty and needs to be replaced.  Please install a new CL-31, CL-41 or CL-51 cartridge to clear this error and resume normal operation of the unit.

I thank you for Your reply, but the color cart nor the black cartridge is the problem. Their both full.
