Maxify MB5440 ink absorber

[PeterBJ]

A weakness of Canon printheads is that they can fail suddenly without any warning like degraded print quality. They can print perfectly one day and have failed when the printer is turned on next day. I think this is what might have happened with the Maxify.

But wouldn't the printer still power up and give an error code?
In this case it just lights up the orange warning light and remains with blank LCD.

Fired up the smaller 2140 after sitting just as long. This was also throwing some error code when turned off, but that's gone and it's working.

Think I'll pull the print head tonight and give it a clean again.
