HP OfficeJet 6950 (De Parys MK40)

In need of attention. It seems to be working perfectly except for the Cyan cartridge. No matter how much I clean the print head or replace the cartridge, it doesn’t seem to help. Useless for colour printing, it has no problem with printing black text - letters, contracts and so on.

Collection only please from the town end if Kimbolton Road.
