Canon Service Tool V3800

After resetting with V3800, always print an EEPROM information page (by clicking "EEPROM" in the tool). Check the "Dd" value (Absorber counter). It should read 0.0 to 0.3. If it says 0.0, you succeeded.

After every 2nd reset, disassemble the printer, remove the sponge pad, wash it, or install an external waste ink tank. 2. Permanent Bricking If you power off the printer during the EEPROM write process, you can corrupt the firmware. The printer will never turn on again (hard brick). 3. Warranty Void If your printer is still under warranty, running this tool flags the service log. Canon technicians will see the counter mismatch and void your coverage immediately.

If you are a printer technician, a small business owner, or a savvy home user who owns a Canon PIXma printer, you have likely encountered the dreaded "5B00" or "5B01" error code. These errors indicate that your printer’s waste ink pad counter is full. While Canon wants you to send the printer to a service center (or buy a new one), professionals use a piece of software called the Canon Service Tool V3800 to bypass this. After resetting with V3800, always print an EEPROM

For newer printers (TS700, TS800, TR8500 series), you likely need a newer tool (V5100, V5300, or V5400). For older printers (MP280, MP495), you need V3400 or V2000. Why Do You Need the V3800 Tool? (The "5B00" Error Explained) Canon printers use a non-replaceable sponge pad at the bottom of the device to absorb ink during print head cleaning cycles. Over time, this sponge saturates. To prevent ink from leaking out of the printer case, Canon programs a counter into the EEPROM. Once that counter hits a specific number (usually around 7,000 to 15,000 pages), the printer hard-locks itself. If it says 0

However, respect the hardware. Use the tool to reset the counter, but do not ignore the physical waste ink pads. Open your printer every two years, air out the pads, and consider installing an external waste tank.

| Method | Cost | Difficulty | Best For | | :--- | :--- | :--- | :--- | | | $10 (Pay per reset) | Easy | Non-tech users with a credit card. | | Manual EEPROM Reset | $5 (Arduino) | Extreme (Hardware) | Hardware hackers who can solder wires to the mainboard. | | New Printer | $60 - $150 | None | Users who don't want to risk ink leaks. | Frequently Asked Questions (FAQs) Is the Canon Service Tool V3800 a virus? No, the legitimate file is not a virus. However, Windows Defender and many antivirus programs will flag it as "HackTool:Win32/Keygen" because it manipulates printer firmware in non-standard ways. This is a false positive, assuming you downloaded a clean copy. Can I use V3800 over Wi-Fi? Technically, yes, but it is highly discouraged. A single network drop during the EEPROM write will corrupt the printer. Always use a USB cable. I clicked "Set" but nothing happened. Why? You likely failed to enter Service Mode correctly. Turn everything off and repeat the button sequence. Also, ensure the printer is in "USB Direct" mode (not wireless). Conclusion: Is the Canon Service Tool V3800 Worth It? Yes. If you own a Canon MG5720, MG6820, or TS6050 and you are handy with computers, the Canon Service Tool V3800 is the difference between a $20 software fix and buying a $150 new printer.
