These tutorials provide step-by-step visual guidance for entering service mode and resetting the 5B00 error manually:
For persistent "Waste Ink Pad" errors that manual buttons won't clear, you may need a reset utility: resetter printer canon g2010
When this counter hits a threshold (often set at roughly 20,000-30,000 pages of theoretical waste), the firmware triggers Error 5B00 . The printer is effectively bricked, refusing all commands. This is a safety mechanism to prevent ink from overflowing onto the user's desk, but it is also an artificial endpoint that often occurs well before physical saturation, especially if the user performs frequent cleaning cycles. Resetting the software doesn't physically empty the waste
Resetting the software doesn't physically empty the waste ink. You should eventually clean or replace the ink pads to avoid actual leaks. Over time, this pad becomes saturated
Inside every Canon inkjet printer lies an absorbent pad (or series of sponges) designed to catch excess ink during print head cleaning cycles, borderless printing, and power flushing. Over time, this pad becomes saturated.
