What are the steps to access service mode on a Canon G2010 printer to clear the 5B00 error?

To access service mode on a Canon G2010, ensure the printer is off and unplugged briefly, then plug it back in. Press and hold the Stop/Reset button, then press and hold the Power button. While holding the Power button, release the Stop/Reset button. Now, press the Stop/Reset button five times consecutively. After the fifth press, release the Power button. The printer should power on, and the power lamp will glow steadily green, indicating it has entered service mode. From here, specific button presses (e.g., three presses of Stop/Reset for waste ink counter clear) can be performed.
