This is the most frequent reset request for the G3400. It requires entering Service Mode first. Step A: Enter Service Mode Turn off the printer but keep it plugged in. Press and hold the Stop (red triangle) button. While holding Stop, press and hold the Power button.
Release the Stop button while still holding the Power button.
Press the Stop button 5 times (some newer firmware versions may require 6 times).
Release the Power button. The green light should flash and then stay solid, indicating you are in Service Mode. Step B: Reset the Counter Once in Service Mode, press the Stop button 5 times. Press the Power button once to confirm the command.
The printer will print a test page (usually a D=000.0 report) to confirm the counter is now zero. Turn the printer off and back on to exit Service Mode. 2. Factory / Machine Settings Reset
Use this to clear network issues or restore default administrator passwords.
Method: Press and hold the Stop button. Release it only after the Alarm lamp (orange) flashes 24 times.
Result: All machine settings, including network configurations, will be initialized to factory defaults. 3. Ink System Reset (Air in Pipes)
If your G3400 has air bubbles in the ink tubes or poor print quality, use the "Ink Flush" reset: Turn on the printer.
Press and hold the Stop button until the Alarm lamp flashes 5 times. canon g3400 reset
Release the button. The printer will begin a deep ink system cleaning (this uses a significant amount of ink). 4. Summary of Reset Codes (Stop Button Flashes)
By holding the Stop button and counting the orange light flashes, you can trigger specific resets: 5 Flashes Ink Flush / Cleaning 21 Flashes Hard Factory Reset (some models) 24 Flashes Complete Initialization of Settings Important Notes
Ink Absorbers: Resetting the 5B00 code only clears the software lock. You should eventually replace the physical felt ink pads (absorbers) inside the printer to prevent ink from leaking.
Service Tool: If manual button combinations fail, you may need the Canon Service Tool (ST5302 or similar) software, which requires a PC connection. To help you further, let me know: Are you seeing a specific Error Code (like 5B00 or P07)? Do you have air bubbles in the colored tubes? Is the printer currently connected to a computer?
Once in Service Mode, you generally need a software tool (such as the Canon Service Tool or Resetter Tool) connected via USB to clear the error counters (specifically the Waste Ink Counter for the 5B00 error).
Warning: Downloading Service Tools from the internet carries a risk of malware. Ensure you trust the source or consult a professional technician.
The Canon PIXMA G3400 is a workhorse known for its MegaTank ink system. However, like all printers, it can suffer from logic errors, stubborn "Error 5B00" messages, or connectivity glitches. Knowing how to properly reset the printer is an essential maintenance skill that can save you a service call.
This guide covers the different types of resets available for the G3400, ranging from simple soft resets to deeper hardware interventions.
If you refilled the magenta, cyan, yellow, or black tanks but the printer still says "Low Ink," you don't need the Service Tool. You need a hard reset of the ink detection. This is the most frequent reset request for the G3400
Every time you clean the print head or print a page, a tiny amount of ink is sprayed into a sponge-like pad inside the machine. This prevents ink from leaking out of the bottom. Once that sponge is saturated, the printer stops working to prevent a catastrophic ink leak. The counter for this pad is digital. Even if you physically clean the sponge, the chip remembers it is full. You cannot fix this without a reset.
Yes. A Canon G3400 reset is the difference between a $50 repair bill (or a $200 replacement printer) and 5 minutes of free software work.
To summarize the process:
By following this guide, you have successfully performed a Canon G3400 reset. Your printer will now function as if it were brand new—saving you money and reducing electronic waste. Just remember to keep an eye on the bottom of your printer for future leaks.
Disclaimer: Modifying your printer using third-party service tools may void your warranty. This guide is for informational purposes. Always wear gloves when dealing with waste ink.
The small office hummed, or rather, it to. Sarah’s Canon G3400, a workhorse affectionately named "Old Faithful" for its unending supply of vibrant ink, had fallen silent. The LCD panel wasn't just flashing; it was panicked—an alternating blink of green and orange signaling the dreaded Support Code 5B00.
"The Ink Absorber is Full," Sarah read from her laptop screen, feeling a cold dread. She had a massive report due in two hours. Replacing the physical ink pads, she knew, was a nightmare of staining her hands for days. She needed a miracle, or at least, a reset. The Digital Escape Artist
Sarah turned to the internet. The consensus was grim: "Take it to a service center." But she didn't have time. She found whispers of a "Service Tool" software, a magical, slightly sketchy file that could bypass the printer's internal memory.
She downloaded a supposed version, but her antivirus screamed in protest. Desperate, she tried a different path—the "Manual Reset," a secret handshake between human and machine that required the precision of a safecracker. The Secret Handshake (How she did it): Turned off the G3400, keeping it plugged in. Held down the Stop (Triangle) button While holding Stop, she held the Power button Step 2: Using the Reset Tool Once in
Released the Stop button (while still holding Power), then pressed Stop five times
Released the Power button. The light flashed rapidly and then settled into a solid, peaceful green. The machine was in "Service Mode." The Final Countdown
"It's just a digital trap," she muttered, her hands hovering over the buttons. She needed to tell the printer she hadn't just cleaned its 'diaper,' but replaced it. She pressed the Stop button five more times to select the reset counter function, then pressed Power once to confirm.
Old Faithful groaned, a sound of churning gears that sounded like a mechanical sigh. It didn't print, but the orange light was gone. The Revival
She turned the printer off and on again. The 5B00 error was gone. She opened her report and hit 'Print.' The printer roared to life, churning out pages, indifferent to the fact that its "absorber" was still, theoretically, full.
"Not today, service center," Sarah laughed, grabbing her report. Old Faithful had one more adventure in it, courtesy of a clever digital handshake.
Note: This story describes bypassing the physical maintenance check. The ink absorber will eventually leak if not actually replaced.
