The first detection unit detects a line voltage in an on-hook state. The second detection unit detects a line voltage in an off-hook state. The third detection unit detects a line current in an off-hook state. The determination unit determines a line impedance based on the line voltage detected by the first detection unit, the line voltage detected by the second detection unit, and the line current detected by the third detection unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Facsimile apparatus, method of controlling facsimile apparatus, and storage medium","description":"A facsimile apparatus includes a first detection unit, a second detection unit, a third detection unit, and a determination unit.
