Windows 11 USB IPP Printer Scanner Issue: What to Check

Microsoft's current notice describes a specific Windows 11 scenario: KB5079473 or later, a USB-connected multifunction printer, and IPP over USB support. The affected non-printing interfaces can include scanning and fax, so the printer may still print while Windows no longer recognizes the full device.

This is a fit check, not a diagnosis for every scanner problem. If the printer is network-connected, single-function, not IPP over USB, or running another operating system, use the ordinary Windows or manufacturer support path instead.

Use the printer's own copy function if it has one. A successful standalone copy shows that the scanner can capture a page without relying on Windows; a failed copy or service message points back toward the device, feeder, or manufacturer support rather than this Windows issue.

Also try one plain print job from the current Windows queue. This keeps a missing scanner function separate from a broader USB, queue, paper, or printer-side problem.

Microsoft says there is no confirmed workaround yet and that it is investigating. In some environments, removing the affected device from Windows and physically disconnecting and reconnecting the USB cable temporarily restores scanner detection.

Use this as a reversible diagnostic step, not as proof that the issue is permanently fixed. Removing a device can discard its Windows queue or settings, so note the printer name and connection details first, and do not remove a work- or school-managed device without permission.

If the known-issue conditions do not fit, or if the scanner remains unavailable after the reconnect check, go to the manufacturer's support page for the exact model, region, Windows 11 version, and system type. Install a current scanner package only when that page identifies it as the supported path.

Do not use a generic driver updater to work around a Windows platform issue. A manufacturer package may restore model-specific scan, feeder, fax, or device-button features, but it cannot guarantee a fix for Microsoft's active known issue.

Stop Windows-side troubleshooting if the printer cannot make a standalone copy, shows a service-only error, grinds, smells hot, leaks ink, or repeatedly disconnects. Use the manufacturer, workplace IT, or a qualified repair path for those conditions.

Keep the update number and the exact Microsoft known-issue conditions in your support request. That is more useful than replacing supplies or trying an unverified rollback.
