If there was and current was continuously flowing through the print head there should be a mark on the paper, also since the print head is not designed for 100% duty cycle I suspect it would not last long. Another possibility is the home position switch is not working. When the 97 is first turned on if it detects the print head is not homed it will turn on the motor in reverse to bring it home and if the home switch never closes it will drive forever, mind you if your printer still has the nylon idler that will soon take care of itself by stripping teeth off the gear. This switch is a reed switch and is activated by a magnet on the print head carrier. Paul. |
