The infrared light is flashing.
The infrared lens of a PowerBook
may be aligned with the infrared
lens of the printer. This indicates
that a connection has been
established between the two
devices.
Position the PowerBook:
• More than 3 feet (1 meter) from the printer.
OR
• So that 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).
