This is Canon's explanation of what this error refers to:

Ink has run out.

Replace the ink cartridge and close the Scanning Unit (Printer Cover).

If printing is in progress and you want to continue printing, press the Stop/Reset button for at least 5 seconds with the ink cartridge installed. Then printing can continue under the ink out condition.

The function for detecting the remaining ink level will be disabled.

Replace the empty ink cartridge immediately after the printing. The resulting print quality is not satisfactory, if printing is continued under the ink out condition.

Try printing a light stripes test page (Troubleshooting, print quality problems, troubleshooting print quality page).

If you do not appear to have many missing jets but the colours are all just wrong it may be that the ink has gone stale. Run a couple of head cleans and you should see the colours start to improve. If it is getting better, all you can do is keep running head cleans until you have replenished all the ink in the printhead well.
This problem is common in situations where a lot of black and white printing is done, with very little colour.
Alternatively, it could be that your wiper/cleaning blade is not cleaning the head properly and is smearing the different coloured inks across the head, or possibly that your printhead is leaking colours but I think the first solution should solve your problem.
Hope this helps.

You are getting leakage from one color cartridge to another. Do deep cleaning and run nozzle check. You may have been using non-Cannon inks. They can corrode the ink cartridge seats due to inferrior quality ink. You may need to replace the print head. Check out Cannon web site under this printer support. Print head is in the $50 neighborhood.

Dear budg,
Error code 5600 in S200 is No Print head Error indicator. In this case, the print head of the printer is faulty so that the printer cannot detect the print head. About the print out, please check if there is enough ink in ink tank to print. If there is enough ink to print, means this bad print out caused by the faulty print head. It seems that you to replace the print head.
Regards,

hi,
Ink-backup mode lets you continue printing with one print
cartridge when the other print cartridge has run out of ink.
Ink-backup mode allows the printer to operate using only one print cartridge. It is initiated
when a print cartridge is removed from the cradle.
Exiting Ink Backup mode
Install two print cartridges in the printer to exit ink-backup mode.


Cheers !!!!
