Trying to rule out variables and the only thing we've done this week which would be different is we re-stocked the HR paper from inkexperts (different batch maybe could this have an affect on colour?) and we refilled our ink tanks, using the same ink that was already in there.
All colours are off, even pure white that should be unprinted isn't white, and we're getting a very faint off-white print over the entire printable area of the page.
Does anyone have any idea what the issue could be?
Any help would be greatly appreciated thank you
