How to Fix Canon G7020 Error 5B00 (Waste Ink Pad Full) - Reset Guide and Solutions

Question:
I'm getting error code 5B00 on my Canon G7020 printer. I understand it's related to the waste ink pad, but how can I fix this issue and get my printer working again?

Answer:

Understanding Canon Error 5B00

The 5B00 error code on Canon printers, including the G7020, indicates that the waste ink absorber (waste ink pad) is considered full by the printer's internal counter.

During cleaning cycles and printing, excess ink is flushed into internal pads designed to absorb waste ink. Over time, the printer tracks this usage and, once a threshold is reached, triggers Error 5B00 to prevent ink overflow inside the machine.

Important Note About This Error

The error is not always due to physically full pads-it is often triggered by a software counter reaching its limit. However, resetting the counter without addressing the physical pads can eventually lead to ink leakage if the pads are truly saturated.

Solution 1: Reset the Waste Ink Counter (Service Tool Method)

Your suggested approach is correct and commonly used:

• Go to eBay.com and search for Canon Service Tool

• Choose the latest version available (newer versions are generally backward compatible with older models like the G7020)

• Download and run the software on a Windows computer

Steps (General Overview):

1. Put the printer into Service Mode (this varies slightly by model, but typically involves holding the Stop/Resume button while powering on).

2. Connect the printer via USB (Wi-Fi usually won't work in service mode).

3. Open the Canon Service Tool software.

4. Locate the "Waste Ink Counter Reset" or similar option.

5. Execute the reset.

This should clear the 5B00 error and allow the printer to operate again.

Solution 2: Clean or Replace the Waste Ink Pads (Recommended Long-Term Fix)

While resetting the counter works, it's only a temporary solution if the pads are actually saturated.

For a more permanent fix:

• Disassemble the printer (requires technical skill)

• Locate the waste ink pads (usually near the bottom of the printer)

• Either:

  • Clean them thoroughly (wash and dry completely), or

  • Replace them with new absorbent material

⚠️ This process can be messy and time-consuming, as the pads may be heavily soaked with ink.

Solution 3: External Waste Ink Tube Modification (Advanced Option)

Some technicians install an external waste ink tube:

• Diverts waste ink outside the printer into a container

• Prevents internal pad saturation in the future

However, this requires modification and is recommended only if you are comfortable working inside the printer.

Common Issues When Using Service Tools

• Some versions of the software may show communication errors

• Certain tools are locked to specific models

• Antivirus software may flag the tool (often falsely)

• USB connection is required (Wi-Fi will not work)

Make sure to:

• Use a compatible version

• Run as administrator

• Disable antivirus temporarily if needed
