PIXMA MG5350 Printing problem. Black text not aligned properly. Tried the alignment fix.

[Kasvet]

My Canon Pixma MG5350 printer has developed a printing prob.

The Black text for documents is not printing properly. Printing of photos appear OK.

Have tried the Check printing pattern and cleaning.... as below.

This is after having also tried the Auto and Manual Alignment fixing instructions and replacing the two Black ink cartridges.

Does this now mean that the printer is U/S ?
