The infrared light is flashing. The infrared lens of a laptop or
notebook computer may be
aligned with the infrared lens of the
printer. This indicates that a
connection has been established
between the two devices. Position the laptop or notebook:
• More than 3 feet (1 meter) from the printer.
OR
• So its infrared lens is not aligned with the infrared lens on the printer
(there should be more than a 30-degree total angle between the two
lenses).
