Ultra electronic 300plus quick start Cleaning the Optics, Cleaning the Magnetic Head if fitted

Cleaning the Optics

1.Using a small, soft lens brush, gently remove dust and debris from the visible mechanism and the brushstrips. Ensure the two light emitting diodes (LED's) adjacent to the Thermal Printhead, are clean and not obscured.

2.Check that the two apertures to the two optical sensors (one is 3mm diameter, the other is a fine slit in a stainless steel strip) are not obscured by debris.

Cleaning the Magnetic Head (if fitted)

1.The Magnetic Head is located beneath the card, between the thermal printhead and the front pinch rollers. To clean the Magnetic Head, manually insert the Cleaning Card into the mechanism and withdraw several times until the head is clean.

CAUTION Take great care not to scratch the surface of the magnetic head with any sharp or abrasive material.
