Fax-capable Modem (inbox driver)
A fax-capable modem is an analog modem that can also send and receive faxes, and Windows Fax and Scan drives it through the same inbox modem driver. These live on in offices and clinics that still send documents over a phone line, and they rarely need any manufacturer software. If faxing fails, confirm the modem is detected in the Modems section and that Windows Fax and Scan is pointed at the right device.
Documented for: Windows 10, Windows 11
Windows Fax and Scan uses the inbox modem driver for supported hardware.
