Protection against abnormality

• When the temperature sensor /1 (TEMS/1), /2 (TEMS/2), /3(TEMS/3), /4 (TEMS/4) is over the prescribed
temperature for a specified time period, it is judged as a high temperature error and the main relay (RY1) is
turned off, then the product is stopped after the first transfer, second transfer and fusing pressure are
stopped/released.
• When the temperature sensor /1 (TEMS/1), /2 (TEMS/2), /3 (TEMS3), /4 (TEMS/4) detect a temperature
of under -50 °C continuously for a specified time period, it is judged as a low temperature error and the
main relay (RY1) is turned off, then the product is stopped after the first transfer, second transfer and fix-
ing pressure are stopped/released.
• The thermostat /1 (TS1), /2 (TS2) shut down the power line to the fusing heater lamp /1 (L2), /2 (L3), /3 (L4)
at 190 7 °C.
±
• The thermostat /3 (TS3) shuts down the power line to the fusing heater lamp /4 (L5) at 160
• When the fusing temperature abnormality occurs, the relay-off status is maintained by latch (SC latch) and
an error message appears on the touch panel.
• After troubleshooting the cause of the error, the SC latch must be released by the software DipSW3-1.
