Step-by-Step Guide: How to Use the Service Tool

Using the service tool requires a specific sequence of operations. If you try to run the software without putting the printer into "Service Mode," it will not work. Follow these steps carefully.

Step 1: Enter Service Mode

This is the most critical step. You must force the printer into a state where it accepts service commands.

Before any software can communicate with your G1000, you must manually put the printer into Service Mode: Power Off: Ensure the printer is plugged in but turned off.

  1. Ensure the printer is turned off but the power cord is plugged in.
  2. Press and hold the Resume/Cancel button (the button with the triangle inside a circle).
  3. While holding the Resume button, press and hold the Power button. The green LED should light up.
  4. Keep holding the Power button, but release the Resume button.
  5. While still holding the Power button, press the Resume button 5 times. (For G1000, usually 5 times is the magic number to enter Service Mode).
  6. Release the Power button
