A key should be used only after the printer passes the readiness checks.<\/p><\/details><details><summary>Can I test the fix without using a key?<\/summary><p>Yes. Use printer detection, WIC Reset Utility readings or Canon service-mode detection before the protected reset.<\/p><\/details><details><summary>Does Wi-Fi work for the reset?<\/summary><p>No. Use a direct USB data connection to Windows 7-11.<\/p><\/details><details><summary>What proves that the problem is fixed?<\/summary><p>Windows detects a stable Canon service device and the printer remains selected in Connect.<\/p><\/details><details><summary>Can a USB hub cause this problem?<\/summary><p>Yes. A hub, dock or splitter can briefly disconnect the printer. Use a built-in motherboard USB port.<\/p><\/details><details><summary>Should other printers remain connected?<\/summary><p>No. Leave only the supported printer connected during diagnosis and reset.<\/p><\/details><details><summary>Does WIC Reset Utility perform the final reset?<\/summary><p>No. Utility reads Epson counters and tests communication. Wic Reset Connect performs the protected reset.<\/p><\/details><details><summary>Does an unused key expire while I troubleshoot?<\/summary><p>No. An unused key has no expiry date before use.<\/p><\/details><details><summary>What if the printer still has another error afterward?<\/summary><p>Record the exact code and indicator pattern. Cartridge, head, scanner, paper-feed or mechanical faults need separate diagnosis.<\/p><\/details><details><summary>Can software replace physical absorber service?<\/summary><p>No. Visible leakage, saturation, damaged tubes or chipped maintenance parts still require physical work.<\/p><\/details><details><summary>Where can I request a replacement after an eligible interrupted attempt?<\/summary><p>Fix the original cause first, then use https:\/\/wicreset.online\/newkey and follow the official replacement procedure.<\/p><\/details><\/section> <section class=\"wr-section
