Ioline FJ Printer & StudioJet Service Manual
1. The paper take up motor will not stop rotating and will pull the
paper tight against the platen. This might result in an X motor
jam and a ‘popping’ noise during printing.
2. The Paper Out sensors will not detect that the paper feed roll is
empty and printing may continue with no paper in the printer.
To replace a defective sensor:
IMPORTANT: Never disconnect or connect sensors to the
machine or electronics when power is on. This will permanently
damage the sensor and might affect the logic board.
1.
Power off the printer.
2. Disconnect the plug from the sensor.
3. Note the orientation of the old sensor, speci fi cally where the
optical ‘eye’ is pointing.
4. Remove the old sensor by removing the hardware or adhesive.
5. Mount the new sensor in exactly the same orientation as the old
one.
6. Connect the plug to the sensor, it is keyed to only connect one-
way.
7. Power on and test the installation.
