Canon MG5750 printing black

[robertford]

Hi, my printer won't print (or copy) in black when Plain Paper is selected in the settings. It just prints the parts of the page that are colour, but not the black. It prints OK on plain paper if I select Glossy Photo Paper in the settings, but then I can't use duplex printing.

I have latest drivers and firmware. Have reinstalled drivers from scratch. Running on Windows 10. 

Tried brand new full cartridges. 

I've tried various documents, Word and PDF and the print test function - all of them have the problem. 

I've done the Nozzle Check Pattern and it looks fine on black and colours, so there appears to be no clogging.

I've run all the maintenance programs such as deep cleaning and print head alignment.

Any ideas?
