HP wifi air printer (Bedford MK42)

This printer HP OfficeJet 6950, is a few years old. Works perfectly in black and white, but there seems to be an issue with the cyan (blue) ink. I’ve tried all I can do to fix it, but to no avail. I spoke with HP, who said it cannot be rectified, and that I needed to buy a new printer. So this has now been replaced. It does come with some spare ink cartridges, and a new cyan cartridge too, just in case. Power lead included. It has a scanner, both flatbed and sheet feed, copies, and prints via the wifi/airprint HP smart app. Other than the awkward blue, it’s still perfect. Collection only from Wixams, any time today/tomorrow or over the weekend. No holding. No show = goes to next person. Thanks
