SOURCE: Error message 5B00 for Cannon Pixma MP630

Waste ink absorber full [5B00]. That means that you have filled the sponge where the cartridges are when they don't print. If you have printed a lot lately, that's quite normal, because every time you print, the cartridges spray some ink that is left on the nozzles and go on that sponge. Open the printer, take the cartridges and the printing head out. Locate the sponges and take a lot of tissues. Clean the mess and i guess it will start working again.

SOURCE: I have Canon Pixma MP450,

Error 5B00 means that your ink absorber is full. you need to reset the counter protection and replace the ink absorber inside the printer.
