- F by the thermistor on the printhead 8 the empty sanction operation may occur depending on the situation 9 if paper remains in the printer the pf roller rotates by steps enough to eject the paper forcibly 99
- L800 l801 revision a 99
- Note 1 the rotation direction of the pf motor is as follows clockwise paper is fed normally counterclockwise paper is fed backward 2 the condition of the cr lock is as follows red cr lock is set white cr lock is released 3 indicates the pg position any position means that the pg position is not recognized because apg is not reset yet 4 checks if the carriage is not deadlock such as the cr lock is caught in the gap of the carriage 5 eject the paper if any 6 when paper exists the existing measurement value saved in eeprom is read out therefore the pf motor does not rotate 7 executes when the detected temperature is under 5 99
