While the Canon Service Mode Tool version 1.050 is a powerful utility, its use requires careful consideration and caution:

The software will send a command to the printer, and the printer will momentarily feed a blank page or print a row of characters confirming the counter reset.
: While holding Power , press the Stop button exactly 5 or 6 times (the exact number depends strictly on your specific Canon model). The alarm LED will flash with each press.
