Hi Tony,
I'm afraid all faulty cartridges must be delt with by the manufacturer directly.
If you follow this link: http://www.microboards.co.uk/rmar.asp you can submit an RMA form (similar to this one you opened) and they will authorise the faulty cartridge for return.
If there is anything else I can help with please let me know.
Kind Regards,
David

Hi Tony
We have received back your ink here - and will post a replacement ink out in the post for you.
Please note in future however any problems with Microboards products should be dealt with directly with Microboards (who are based in the UK) - thanks.
Please note this ticket will now be closed.
Kind regards,
Jen Holden
