EEPROM Operations: Allows users to read and save EEPROM data to diagnose technical issues.

Maintenance Functions: Includes options for test printing, cleaning the print head, and checking sensor statuses.

Region Settings: Facilitates changing the printer’s regional firmware settings if needed. Compatibility & System Requirements

Operating Systems: Best suited for Windows XP and Windows 7; newer versions may require running in "Compatibility Mode".

Connection Type: Must be connected via a USB cable; the tool typically does not function over Wi-Fi. Supported Models: iP Series: iP2700, iP4800, iP4900, iP5800. MG Series: MG2100, MG3100, MG5100, MG5200, MG6100. MP Series: MP230, MP280, MP490.

Because Canon does not officially distribute this tool to the public, users often download it from third-party sources. Exercise extreme caution to avoid security risks:

I understand you're looking for information about the Canon Service Tool V3900 — but I need to start with an important caution.

This tool is proprietary service software intended only for authorized Canon technicians. It’s often used to reset waste ink counters, perform print head cleaning, or enter service mode on Canon printers (especially PIXMA models). Downloading it from unofficial “hot” or cracked sources is risky: those downloads frequently contain malware, keyloggers, or corrupt firmware.

If you still want a general informational write-up (not an endorsement or direct link), here’s what you should know:

Legitimate Alternatives

Instead of risky downloads, consider:

1. Canon Authorized Service Center – they’ll reset the counter properly for a fee (often $20–50).
2. Third-party reset utilities from reputable sources (e.g., WIC Reset Utility) — these are commercial but safer.
3. Manual reset via button sequences on some older models (check your printer’s service manual).
4. Replacing the waste ink pads physically and then using a legitimate service tool obtained through authorized channels.

Step 3: Reset the Counter

1. Look for the "Ink Absorber Counter" section in the tool interface.
2. Select Main or Platen (usually, resetting 'Main' is sufficient for error 5B00).
3. Click Set.
4. Finally, click Clear or EEPROM Clear to reset the waste ink counter to zero.

The Critical Warning: Risks of Downloading "Hot" Service Tools

Before we proceed, a major red flag: Searching for "canon service tool v3900 download hot" leads you into dangerous territory. Here is why:

What is the Canon Service Tool V3900?

The Canon Service Tool V3900 is a proprietary, low-level utility software designed by Canon for authorized service centers. Unlike the standard printer drivers or the "Canon IJ Printer Assistant Tool," this software is not intended for everyday consumers.

Its primary purpose is to:

• Reset Waste Ink Pads Counters (Absorber Full Error - 5B00/5B01)
• Change USB IDs for refurbished or repaired printers
• Perform EEPROM initialization (resetting the printer’s internal memory)
• Enter Service Mode on newer Canon PIXMA and MAXIFY models (G-series, TS-series, TR-series, and MG-series)

Canon Service Tool V3900: The Ultimate Guide to Download and Resetting Your Printer

If you are reading this, chances are your Canon printer has stopped working, flashing an error code like 5B00, and you are staring at a message saying "Ink Absorber Full."

Don't panic. You do not necessarily need a repair shop. The solution often lies in a small but powerful piece of software: Canon Service Tool V3900. This tool is currently one of the most sought-after utilities for resetting specific Canon printer models.

In this post, we cover what this tool does, which printers it supports, and how to use it safely.

Step 4: Restart

Turn the printer off and turn it back on. The error should be gone, and your printer should be ready to print.

3. Manual EEPROM Reset via Serial Interface

For advanced users, you can solder wires to the printer’s mainboard and reset the EEPROM using a Arduino or FTDI adapter. This method is firmware-agnostic but voids warranties and requires electronics skill.

Option 3: Run in a Sandboxed Environment

Before running V3900, use:

• Windows Sandbox (Pro/Enterprise editions)
• VirtualBox with an isolated Windows 10 VM
• Bitdefender’s Sandbox

This prevents the tool from accessing your host OS files, browser passwords, or network.
