# **🛑 FIXED: OKI Printer "Driver Unavailable" or "Setup Incomplete" (2026)**

If your OKI C-Series or MC-Series printer is displaying a "Driver is unavailable" error or the OKI Mobile Print app is stuck, follow these steps:

**Quick Fix: Manual Port Mapping**

OKI printers frequently lose connection when Windows uses generic "WSD" ports. You must switch to a static TCP/IP port.

Open Printer Properties > Ports > Add Port.

Select Standard TCP/IP Port.

Enter the IP Address of your OKI printer.

Uncheck "SNMP Status Enabled" if the printer still shows "Offline."

**⚠️ OKI CONNECTIVITY & FIRMWARE HELP** If you are seeing "Service Call 0x..." or if your software refuses to finish the setup on Windows 11/12, your printer requires a manual firmware patch.
