Electrodes on Feeder / Feeder Bank
When electrodes on the feeder bank and the tape feeder get dirty, clean them as follows:
NOTE: If the electrodes are touched by hand or have come into contact with foreign matter, cleaning is
recommended even if no dirt can be observed visually.
ACTION: Clean the electrodes by wiping off dust gently with a dry cotton swab or non-woven fabric. When cleaning
them, check that the pins are not bent. If they are bent excessively, contact i-PULSE for repair. Continuing
to use them if the pins are bent may scratch the contact surface of the feeder bank.
Do not use alcohol, water base detergents and organic solvent, such as
thinner, benzene and acetone.
Do not use sandpaper and tools with sharp blade or edge, such as a knife and
a screwdriver.
NOTE: If they get stubborn stains, try not to get rid of them forcedly. Please contact us.
