What Is Canon Support Code 6801?

Canon Support Code 6801 is a general internal printer error. Unlike paper jam or ink cartridge errors, this code usually points to a problem with the printer’s internal hardware, firmware, or control system rather than a user-replaceable component. Canon recommends turning the printer off, unplugging it, restarting it, and contacting an authorized service center if the error remains.

Common symptoms include:

• Printer won’t start normally
• Error 6801 displayed on the LCD
• Printing stops unexpectedly
• Printer becomes unresponsive
• Continuous error message after restart

Common Causes of Canon Support Code 6801

Several issues can trigger this error.

Internal Hardware Failure

A malfunctioning logic board, memory component, or internal sensor may prevent the printer from completing its startup sequence.

Interrupted Firmware Process

If the printer loses power during a firmware update, internal software may become corrupted.

Power Supply Problems

Voltage fluctuations or unstable electrical connections can trigger startup errors.

Main Board Communication Failure

Internal electronic components must communicate correctly during startup. If communication fails, the printer displays Support Code 6801.

Internal Mechanical Fault

A damaged carriage assembly, sensor, or motor may prevent proper initialization.

How to Fix Canon Support Code 6801

Follow these troubleshooting steps in order.

Step 1: Restart the printer.

A simple restart clears many temporary errors.

1. Turn off the printer.
2. Unplug the power cable.
3. Wait for 2–5 minutes.
4. Plug the printer back in.
5. Turn it on again.

If the error disappears, no additional troubleshooting is necessary.

Step 2: Check the Power Source

Power instability can cause startup failures.

Make sure:

• The power cord is firmly connected.
• The outlet is working properly.
• You are not using a faulty extension cord.
• The printer is connected directly to a wall outlet.

Step 3: Disconnect External Devices

Remove every external connection except the power cable.

Disconnect:

• USB cable
• Ethernet cable
• Memory cards
• USB flash drives

Restart the printer afterward.

Step 4: Inspect the Printer for Obstructions

Open the printer cover and check for:

• Torn paper
• Packing material
• Foreign objects
• Stuck carriage
• Loose ink cartridges

Do not force any moving parts.

Step 5: Perform a Soft Reset

A soft reset can eliminate temporary software glitches.

1. Turn off the printer.
2. Unplug the power cable.
3. Wait at least two minutes.
4. Reconnect the power.
5. Turn the printer back on.

This process does not erase your printer settings.

Step 6: Update Printer Firmware

If the printer starts successfully after restarting, check whether a firmware update is available using Canon’s support resources. Firmware updates can resolve known software issues and improve stability.

When Canon Support Code 6801 Requires Professional Repair

If the error continues after basic troubleshooting, the problem is likely related to an internal hardware component.

Possible failed parts include:

• Main logic board
• EEPROM memory
• Internal sensors
• Power supply board
• Control circuitry

These components generally require diagnosis and replacement by an authorized Canon technician.

Can You Reset Canon Support Code 6801?

A factory reset may help if the printer is still accessible through its menu.

If the printer boots normally:

1. Open Settings.
2. Select Device Settings.
3. Choose Reset Settings.
4. Confirm the reset.
5. Restart the printer.

If the printer cannot reach the menu because of the error, a factory reset usually isn’t possible.

How to Prevent Canon Support Code 6801

Although hardware failures cannot always be avoided, good maintenance reduces the risk.

Follow these best practices:

• Keep firmware updated.
• Use a surge protector.
• Avoid unplugging the printer while it’s operating.
• Turn the printer off properly.
• Keep the printer clean and dust-free.
• Use genuine Canon ink cartridges when possible.
• Place the printer on a stable surface.
• Avoid frequent power interruptions.

Quick Answer

What does Canon Support Code 6801 mean?
