Printer not printing black only faint grey outlines

[Kevdrwg]

I have never been able to print full black on my printer its as though there's a pencil outline but no full black lettering. I've tried all cleaning and alignment and hard reset etc.  Also tried all options for print quality.  I'm using instant ink and have upgraded to a paid plan because I'm doing so many tests of single pages to try and get it right.  Colour is coming through strong but not the black.  Tried all paper options and best quality and photo options but it refuses to print a full black section.  Faded and outlined barcodes and QR  are no good for scanning please help me before I throw it out the window 😕
