What does the 5b00 error code signify on a Canon G2000 series printer?

The 5b00 error code on a Canon G2000 series printer indicates that the waste ink absorber pad (also known as the maintenance cartridge or ink absorber full error) is at or near its capacity. This pad collects excess ink from print head cleaning cycles and borderless printing. The printer's internal counter tracks this usage, and once a certain threshold is reached, it triggers this error to prevent ink overflow and potential damage.
