Canon TS8050 printer with spare ink (only printing B&W) (Peppard Common RG9)

The yellow cartiridge has stopped working (tried the printer clean setting but didnt clear it). It prints B&W / scans / photocopy / etc fine - and with a bit of time it's possible the yellow could be cleaned to print in colour again. A box of spare ink cartridges with it. Collection from Peppard Common.
