Canon Pixma MG7150 printer and scanner. Worked well, until it didn't - last week. Error message B200 - indicates that a new print head is required. As I have another printer, this is surplus to requirements.
It is not difficult to replace the print head - there's a good YouTube video for the exact model.

OEM (Canon) print heads are quite pricy and copies appear to be unreliable. The print head model number is QY6-0083. There is a set of cartridges with it, some partly used. Taker collects.
