Many malicious websites wrap the executable file in malware, adware, or trojans. Always scan any downloaded .exe or .zip archive using robust antivirus software before opening it.
To use the tool effectively, your printer must be in "Service Mode." If the printer is in its normal state, the software will not detect it. Turn off your printer. Hold the Stop/Reset button. While holding Stop, press and hold the Power button. Release the Stop button (keep Power held).
Ensure the printer is plugged in but turned completely off.
Press and hold the Stop / Reset button (the red triangle inside a circle).
