I have no idea how the RX510 is built though so if you do decide to go
ahead can you take a lot of digital photos of each stage, what you can
see, etc... and I can use those to write up a guide specifically for
your version (at some point)..

Thank you both for your response,
As I had already reset the counter and from information I gathered apparently
the ink pad may be only 50% full I will leave well enough alone at the moment.
FYI Martin the printer has a "door" on the back of it held in place by a Philips
screw - and when removed you can see the ink tube coming from the head parking
area to a large area of felt which at the moment only seems damp.
To remove the tube and take it outside the printer looks "too easy" so I will wait
until - if and when - it starts to leak externally - then I'll tackle the thing seriously.
Once again thank you both for your response and help.
