Orange light flashing on canon mp630 printer where is the waste ink

SOURCE: Canon i9950

Five flashes: Print head not installed / Print head not installed correctly / Defective print head
Install the print head. If the print head is already installed, remove the print head and check the electrical contacts for foreign matter, then reinstall.
For the i9950 ONLY: When the CD-R tray is set in the printer, remove the CD-R tray and set the paper output tray to the paper print position, then install the print head.
After reinstalling the print head, you may need to realign it.
If this error still remains, the print head may be damaged

Yes, the flashing light on start-up is actually the Waste Ink pad is full
a Canon tech suggests that the job is very difficult (unfortunately even for them)
HOWEVER....good news is that you can override it for awhile...

• turn off power
• press & hold RESUME button, then press POWER button
• continue to hold POWER then release RESUME button
• Press RESUME Button 2x quick
  
• Release both RESUME and POWER
• Green light will now blink, then stop
• With Green light on....press RESUME 4x
• Push Power button to turn printer off
