Make sure the person sending the fax has a fax machine capable of sending colour faxes.
If one or more of the ink cartridges are empty, the machine cannot receive a colour fax. While memory is available, black and white faxes will be received into memory.
The FAX/MFC will stop all print operations such as printing copies, faxes and jobs from the PC when one or more of the ink cartridges are empty.
