Cause
The engine soft SW8-3 in SIM55-1 is set to "1".
The PTC control is not executed. (The PTC does not
operate.)
When the engine soft SW8-3 in SIM55-1 is set to
"1", the PTC output, the heater control, and the error
detection are disabled. When this setting is made in
case of a PTC unit trouble, the PTC function is
disabled regardless of the PTC trouble and printing
operation can be performed.
The PTC control is not executed. (The PTC does not
operate.)
