Ip7250 - Disc label not printing black anymore.. On normal paper it does however!

[avigoorn]

HI!

I am using "droppix" label maker to do my label printing for many years now. With my ip7250 and another canon before.

Since like 3/4 weeks when printing a disc label it seems the black color does not work any more. 

When I print the EXACT same label from droppix on a normal a4/letter paper, it will print the black color just normal.

I have no clue why it does not print black when using the disclabel. Does it use another black cartridge? like the big one on normal paper, and the small one for the labelprint?

I have reinstalled the drivers of the printer. But this does not help.

Is my printer broken??? 

Please advice or solution! :)))

thanks Arnaud!
