Problem Cause Solution
Printing does not start. If the printer is using wireless
LAN (IEEE802.11g/b),
when there is a microwave
oven, mobile phone,
industrial machine, scientific
instrument, or medical
instrument which uses the
same frequency range near
the device, radio waves may
be interfering with the
wireless LAN's
communication.
Turn off the microwave oven, mobile

instrument, or medical instrument which
uses the same frequency range and
then try printing again. If printing is
successful, move the device to a
