Can You Use a Printer After Removing the Wi-Fi Module? Here's What You Need to Know

Question:
I removed the Wi-Fi module from my printer because I don't need wireless printing. However, after removing it, my printer stopped printing altogether. Is there a way to use the printer without the Wi-Fi module connected?

Answer:

Now, regarding your question about removing the Wi-Fi module, the short answer is that most printers-especially modern Epson and Canon models-cannot operate properly without the Wi-Fi module installed, even if you never use wireless printing. Here's why and what you can do about it:

1. Why the Printer Stops Working Without the Wi-Fi Module

Even though the Wi-Fi board's main function is wireless connectivity, it's also tied into the printer's main logic circuit. Manufacturers design these boards to act as part of the printer's communication chain. When removed, the printer's motherboard detects a hardware fault and stops normal operations.

In other words, the printer expects a signal from the Wi-Fi board during startup. If it doesn't receive that handshake, it assumes there's a communication error or missing component, which prevents printing-even via USB or Ethernet.

Some models may also trigger internal error codes such as:

• Error 0x97 / 0x9A (Epson) - indicating a general hardware failure.

• Service error B200 or 6800 (Canon) - caused by disrupted communication between mainboard and secondary modules.

2. Possible Fixes or Workarounds

Option A: Reinstall the Wi-Fi Module

The simplest and most reliable solution is to reinstall the original Wi-Fi module. Even if you don't plan to use Wi-Fi, the module must remain connected to complete the electrical and data circuits that the printer's firmware relies on. Once reattached, the printer should pass its self-check and resume normal operation.

Option B: Use a Replacement or Dummy Board

If your Wi-Fi board was damaged or removed permanently, you can try sourcing a replacement board from a donor printer of the same model. In some cases, technicians have used a dummy plug or resistor network to simulate the board's presence-but this requires detailed circuit knowledge and isn't recommended unless you have electronics experience.

Option C: Firmware Override (Advanced)

On certain service-level firmware versions, technicians can disable Wi-Fi communication checks through EEPROM editing or firmware recovery tools (such as WICReset or service utility software). However, this process is risky and could permanently brick your printer if done incorrectly. We don't recommend it unless you have access to the correct binary dump files and a way to restore the chip if it fails.

3. Safer Alternatives to Removing the Wi-Fi Board

If your goal was simply to disable Wi-Fi (for security or power reasons), you can safely do this through the printer's settings menu:

• Disable Wi-Fi under Network Settings → Wireless LAN → Off.

• Alternatively, reset network settings or enable Ethernet-only or USB-only modes.

This keeps the hardware intact while preventing the printer from broadcasting or connecting wirelessly.
