G4510 Canon printer printing blank pages
I have an iMac set up with a G4510 Canon printer. I am working on Mac OS Mojave Version 10.14.6.
I printed off it 2 days ago in black and white and it printed fine.
Today it is feeding through the paper but the pages are white.
I assume it is because the heads need cleaning but I don't know how to do this.
Does anyone have any idea how to do this?
Thank you
iMac 27″, macOS 10.14
