Sensor Operational Check

Function
This function allows you to check that the seven sensors (document front sensor, document
rear sensor, cover sensor, paper ejection sensor, paper-edge sensor, ribbon sensor, and
hook switch sensor*) operate correctly.
In the FAX1010 and those versions equipped with a Binatone handset, the LCD shows the
"FRERCJMPHRX
- the document front and rear sensors detect no paper (FRE),
- the recording paper cover ASSY is closed (RC),
- the paper ejection sensor detects no paper jam (JM),
- the paper-edge sensor detects paper loaded and the paper front cover is closed (PH),
and
- the ribbon sensor detects the ribbon cartridge loaded (RX).
In other models, the LCD shows the "FRERCJMPHRXHK 1" when
- the document front and rear sensors detect no paper (FRE),
- the recording paper cover ASSY is closed (RC),
- the paper ejection sensor detects no paper jam (JM),
- the paper-edge sensor detects paper loaded and the paper front cover is closed (PH),
- the ribbon sensor detects the ribbon cartridge loaded (RX), and
- the hook switch sensor detects the on-hook state (HK).
