Question about Canon BubbleJet i9950 InkJet Photo Printer
Seems impossible to reset the counter, is there a way to manually reset?

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

No, it has nothing to do with the waste ink pad.
From the cannon manual for service technicians:
5 times The print head is not installed ,
or it is not properly installed (EEPROM data of the print head is faulty) [1403/1405].
Install the print head properly, and close the access cover.
Or, with the print head installed, turn the printer off and on.
8 times Warning: The waste ink absorber is
almost full (approx. 95% of the maximum capacity). 
Pressing the Resume/Cancel button will exit the error, and
enable printing. ...

Had a problem with a Canon i9950 CD tray not operating or printing.
Took to a specialist and was quoted $582 to repair.
Tried the old blank media I had used as opposed to new cheaper media i was using, and ...... problem solved.

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...
remember to rate the solutions...anything less than FIXYA actually lowers my rank...I didn't make the system...just wanting everyone to understand the impact of their vote....so if you need further help...just ask....hope it fixya'd...if it did then rate please!
