Problem Causes Solutions
Printing via wireless LAN is
slow.
• A communication error
might have occurred.
• Interference from other
wireless LAN devices
can reduce the
communication speed
• If the printer is using a
wireless LAN, radio
waves may be
interfering with the
wireless
communication. This
may occur if there is a
microwave oven,
cordless telephone,
industrial printer,
scientific instrument, or
medical instrument
using the same
frequency range near
the device.
• Move the printer farther away
from the wireless LAN device.
• If there are active wireless LAN
devices nearby, move the printer
or disable those devices.
• Turn off other printers or
instruments that use the same
frequency range, and then try
printing again. If printing is
successful, move the devices to a
location where they do not
interfere with the printer.
If the problem cannot be solved, contact your service representative.
