Problem Cause Solution
A print process using
wireless LAN is slow.
• A communication error
might have occurred.
• Interference from other
wireless LAN devices
can reduce data
transmission speed.
• If the machine is using
a wireless LAN (IEEE
802.11b/g/n), radio
waves may be
interfering with the
wireless
communication. This
may occur if a
microwave oven,
cordless telephone,
industrial machine,
scientific instrument, or
medical instrument
using the same
frequency range is
placed near the device.
• Move the machine away from the
wireless LAN device.
• If there are active wireless LAN
devices nearby, move the
machine or disable those devices.
• Turn off other machines or devices
which use the same frequency
range, and then print again to
check whether the devices cause
interference. If printing is
successful after you turn off the
power, then it is possible these
devices are the cause of the
interference. Move the devices to
a location where they do not
interfere.
If the problem cannot be resolved, contact your service representative.
