G6020 printing everything with pink

[gnordwig]

We have a Cannon G6000 series ink jet printer. When trying to print in either black and white or in color pages are coming out pink. How can we fix this?

It is a Cannon G6020. We are connected by both USB and WiFi. Our computers are Macs. The tower is an old Mac which no longer can be updated and has OS 10.13.6 and the other computer is a brand new Air Book which has Sequoia 15.3. When printing there are no error messages. The only message is "The latest firm wave is on the printer" We get the same problem with both computers.
