EPSON Stylus Pro 7600/9600 Revision A 3.2.4.16 PF motor PWM output faulty (00010010) Explanation: There may be a case where a current exceeding the specified value flows during PF Motor operation. In such a case, this message is displayed and the printer stops operating. This error can be displayed in the following case: an abnormal load which does not reach the level causing an out-of-step phenomenon 00010001 in the paper feed drive system has occurred and the running speed of the motor has been detected to be too low, so that the current is increased to raise the running speed of the motor. Thus, this message appears to prevent the PF Motor from being overheated. Cause of trouble: • A small PWM output is kept on for a certain period of time (load is kept applied). • Paper feed related mechanism out of step. Remedy/Points to be checked: 1. Check the load on the PF Motor. • Measure the resistance value of the PF Motor (5.8Ω) If the PF Motor is found in short mode, replace the C472MAIN Board at the same time. • Running load of PF Motor (check by manual operation) • Rotation load of PF Roller 2. Replace the PF Motor (p.185). 3. Replace the MAIN Board (C472 MAIN) (p.207). 3.2.4.17 Head driver (TG) temperature error (0001001B) Explanation: During printing operation, there may be a case where the temperature inside the print head has risen above the specified value and the thermistor in the print head detects it as abnormal temperature. In such a case, this message is displayed and the printer stops operating. Cause of trouble: • Head broken down. • Faulty contact of tape electric wire, broken wire or wire out of position. Remedy: 1. Turn off the power to the printer once and turn it on again and check for recovery. 2. If the same error occurs immediately or in a short time, replace the print head with a new one.
