Canon Pixma MG3650S Ink absorber full code. ??!!

[Brian Lacey]

Canon Pixma MG3650S Warning message flashed up
Support Code : 1702 The ink absorber is almost full. Press the printer's Start button to continue printing. Contact the service center.

I have tried Google but can't get the code to clear and machine reset itself, just used for domestic use. Anyone know how to reset the blooming thing ? !!!! Sending it to Canon costs more than buying a new one !

Thanks
Brian.
