Proof of correction

Windows detects a stable Canon service device and the printer remains selected in Connect.

Final activation-key operation

Obnovení funkce Wic Connect

Use Connect only after the printer is ready. One purchased key performs one completed reset on one supported printer.

Buy one reset key
When an attempt was interrupted

Correct the cause before requesting a replacement

An eligible interrupted reset can use the official replacement procedure, but another key will fail for the same reason when the USB, driver, service mode or printer error remains unresolved.

Keep one printer connectedRemove extra Epson and Canon devices.
Keep the key unused during testingUse detection and readings first.
Record the final proofWindows detects a stable Canon service device and the printer remains selected in Connect.
Separate other faultsCounter reset does not repair unrelated hardware errors.
OKready state
Verification

Windows detects a stable Canon service device and the printer remains selected in Connect.

Only after this condition is stable should the protected reset continue. A repeatable readiness check protects the activation key and makes the final result easier to verify.

Frequently asked questions

Canon Not Detected in Service Mode: Diagnose the Sequence FAQ

What does “Canon printer not detected in service mode” usually mean?

Windows does not enumerate the Canon after the button sequence, so Wic Reset Connect has no service device to select.

Should I enter another activation key immediately?

No. Diagnose and correct the setup first. A key should be used only after the printer passes the readiness checks.

Can I test the fix without using a key?

Yes. Use printer detection, WIC Reset Utility readings or Canon service-mode detection before the protected reset.

Does Wi-Fi work for the reset?

No. Use a direct USB data connection to Windows 7-11.

What proves that the problem is fixed?

Windows detects a stable Canon service device and the printer remains selected in Connect.

Can a USB hub cause this problem?

Yes. A hub, dock or splitter can briefly disconnect the printer. Use a built-in motherboard USB port.

Should other printers remain connected?

No. Leave only the supported printer connected during diagnosis and reset.

Does WIC Reset Utility perform the final reset?

No. Utility reads Epson counters and tests communication. Wic Reset Connect performs the protected reset.

Does an unused key expire while I troubleshoot?

No. An unused key has no expiry date before use.

What if the printer still has another error afterward?

Record the exact code and indicator pattern. Cartridge, head, scanner, paper-feed or mechanical faults need separate diagnosis.

Can software replace physical absorber service?

No. Visible leakage, saturation, damaged tubes or chipped maintenance parts still require physical work.

Where can I request a replacement after an eligible interrupted attempt?

Fix the original cause first, then use https://wicreset.online/newkey and follow the official replacement procedure.

Ready to continue safely?

Confirm the setup, then use one activation key

Fix the actual cause, keep one printer connected by direct USB and use Wic Reset Connect only after the free readiness checks succeed.
