What Is Canon Printer Error 1703?

Canon Printer Error 1703 is generally associated with the printer’s ink absorber or waste ink management system. During printhead cleaning cycles, excess ink is collected inside absorbent pads within the printer. If the printer detects that these pads are becoming saturated or senses an abnormal condition, it may display Error 1703.

In some cases, the error may also appear due to:

• Excess ink buildup
• Internal ink leakage
• Incorrect installation after cartridge replacement
• Sensor detection issues
• Firmware glitches

The printer may stop printing until the issue is resolved.

Common Causes of Canon Printer Error 1703

Several factors can trigger this error.

Waste Ink Absorber Becoming Full

Every cleaning cycle sends unused ink into absorbent pads. Over time, these pads fill up and require servicing.

Excessive Printhead Cleaning

Running multiple cleaning cycles in a short period increases waste ink accumulation.

Ink Leakage Inside the Printer

Leaking cartridges or overfilled ink tanks may cause excess ink to reach the maintenance area.

Dirty Internal Sensors

Ink residue can interfere with sensors responsible for monitoring the printer’s maintenance system.

Firmware or Software Issues

Occasionally, outdated firmware or temporary software glitches can generate false error messages.

Signs That Accompany Canon Printer Error 1703

Besides the error message, you may notice:

• Printing suddenly stops
• Orange warning light flashing
• Maintenance warning on the LCD display
• Frequent printhead cleaning cycles
• Ink smudges inside the printer
• Reduced print quality
• Printer refusing to accept new print jobs

Recognizing these symptoms can help identify the underlying cause more quickly.

How to Fix Canon Printer Error 1703

Follow these troubleshooting steps in order.

Restart the printer.

A simple restart can clear temporary software glitches.

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

If the error disappears, it was likely a temporary firmware issue.

Inspect the Ink Cartridges

Open the printer cover and verify:

• Cartridges are seated correctly.
• Protective tape has been removed.
• No cartridge is leaking.
• Cartridge contacts are clean.

If necessary, reinstall the cartridges before restarting the printer.

Check for Excess Ink

Carefully inspect the maintenance area for visible ink buildup.

Look for:

• Ink pooling near the parking station
• Ink around cartridge holders
• Excess residue on internal plastic parts

If visible ink is present, gently clean accessible areas using a lint-free cloth.

Avoid touching electrical components.

Clean the Paper Path

Sometimes ink residue spreads into the paper feed path.

Remove:

• Torn paper
• Dust
• Small debris
• Excess ink residue

This helps prevent sensor misreadings.

Update the printer driver.

Driver problems can occasionally interfere with printer communication.

Ensure you have:

• Latest Canon printer driver
• Updated printer firmware
• Current operating system updates

Restart the computer after updating.

Reset the printer.

A soft reset may clear temporary maintenance warnings.

1. Turn the printer off.
2. Disconnect power.
3. Wait 60 seconds.
4. Reconnect power.
5. Restart the printer.

If Error 1703 returns immediately, the issue is likely hardware-related.

When the Waste Ink Absorber Needs Service

If the absorber pads are genuinely saturated, cleaning alone may not solve the problem.

Professional servicing may include:

• Replacing waste ink pads
• Cleaning internal sensors
• Resetting the waste ink counter using Canon service software
• Inspecting for internal ink leakage

Attempting to disassemble the printer without proper knowledge may cause additional damage.

Common Mistakes to Avoid

Avoid these common troubleshooting mistakes:

• Running repeated printhead cleaning cycles unnecessarily
• Ignoring ink leaks
• Touching internal sensors with bare hands
• Using incompatible cartridges
• Forcing paper through the printer
• Continuing to print despite repeated maintenance warnings

These actions can worsen the problem.

Preventing Canon Printer Error 1703

Regular maintenance can significantly reduce the chance of seeing this error.

Best practices include:

• Print regularly to reduce excessive cleaning cycles.
• Use genuine or high-quality compatible ink cartridges.
• Clean the printer interior every few months.
• Avoid overfilling refillable tanks.
• Update printer firmware when available.
• Store cartridges properly.
• Keep the printer in a clean, dust-free environment.

Preventive maintenance extends printer life and improves print quality.

Quick Answers

What does Canon Printer Error 1703 mean?

It usually indicates an issue with the printer’s waste ink absorber system, excess ink buildup, or maintenance detection.

Can I continue printing?

In many cases, the printer will stop printing until the issue is resolved.

Does Error 1703 always require repair?

No. Temporary software glitches or cartridge issues can sometimes trigger the error, and a restart or basic maintenance may resolve it.

Frequently Asked Questions

Is Canon Printer Error 1703 dangerous?

No. It is a maintenance warning designed to protect the printer from ink overflow.

Can I reset Canon Printer Error 1703 myself?

A basic power reset may clear temporary issues. If the waste ink absorber is full, the printer may require professional servicing and a waste ink counter reset.

Does replacing the ink cartridge fix Error 1703?

Only if the error is caused by a leaking or improperly installed cartridge. It will not resolve a full waste ink absorber.

Can third-party ink cause this error?

Low-quality or leaking cartridges may contribute to excess ink buildup and maintenance issues.

How can I prevent this error in the future?

Perform routine maintenance, avoid unnecessary cleaning cycles, use quality ink, and keep the printer clean.

Conclusion

Canon Printer Error 1703 typically points to a maintenance-related issue involving the waste ink absorber system or excess ink buildup inside the printer. Fortunately, many cases can be resolved by restarting the printer, inspecting the cartridges, cleaning accessible areas, and ensuring the latest drivers are installed. If the error persists after troubleshooting, professional servicing may be necessary to replace the waste ink pads and reset the maintenance counter. Regular printer maintenance and responsible ink usage are the best ways to prevent Canon Printer Error 1703 from recurring.
