Question about Canon PIXMA MP780 All-In-One InkJet Printer
Service error 5C00 is a purge unit error. The purge unit like a spitoon to the printhead where is stops. There is a sensor in the purge unit; when it is blocked (usually by ink build up), that error is given. The error indicates that the purge unit may be full or at least gunked up. It may be possible to clean the purge unit and sensor to make the error go away. I base this on information learned with experience on another Canon product (Model i560). Hope this helps...

if your printer is flashing 4 orange and then back to green repeatedly - i found a solution to it for my ip90v - i opened the printer and checked the right hand side cogs - carefully turn them and you may see that some stray paper jam debris is blocking the cleaning unit from returning to its home in the bottom front of the printer - carefully remove it and replace the casing - turn on and with any luck you will have a dully functioning ip90 like i did.
Hope it helps some others out

Canon USA has a down loadable file for the manual.
Here is the link.
Here is what is being said of this error on the forums:
Fixing this error is much easier as it looks. Unplug the printer completely. Move the ink cartridge cradle gently to the left. Over to the right at it's usual resting place you will see a small pad about 1cm square. This pad and the area around should be covered with ink. Get a microfibre cloth and press down on this pad - it's not fixed so should come away with the cloth, otherwise use tweezers gently. Squeeze the pad several times between your thumb and forefinger while inside the microfibre cloth to remove ink build up. Then when not much ink comes out on the cloth, clean the area in the printer around the pad so that looks free from ink too. Then position the pad back in place, move the cradle back into position, plug in and switch on - should work fine now. But it's worth checking for any paper caught near the ink pad
