2 Is the power cable damaged? Inspect the power cable for signs of damage.
If possible, try using another printer power cable.
Purchase a new power cable specifically
designed for this printer, from the sales outlet or
dealer where you bought the printer from. Never use
any other power cable but the power cable specifically
designed for this printer.
3 Is electricity coming to the power outlet
feeding the printer? Connect another electrical appliance to the power outlet
to check for power. If there is a problem with the main
power, check if electricity is coming to the building. Also
check if power failure has occurred.
4 Has the power fuse of the building
blown, or has the circuit breaker been
tripped?
Replace the power fuse and reset the circuit breaker.
No. What to check Remedy
1 Is the printer head dirty, or is there any
label stuck to the print head? If the print head is dirty, wipe off the
dirt with the supplied cleaning set. If
a label is stuck to the print head, take
it away. * Do not use metallic object
to remove it (the print head may be
damaged). If glue of the label is stuck
to the print head, wipe it off with the
supplied cleaning set.
2 Are you using genuine SATO paper
and carbon ribbons for the LM Basic? Be sure to use genuine paper and carbon ribbon
specifically designed for the printer.
3 Is the paper sensor dirty? If the paper sensor is dirty, wipe off the dirt with
the supplied cleaning set. See Section 4: Cleaning
and Maintenance.
4 Is the carbon ribbon wound correctly? If the knob of the ribbon-winding unit is not set to
its original position, remove the carbon ribbon
already wound, and return the knob to its original
position.
5 Is the data/signal sent from the
computer correct? Turn on the power switch again.
If the message still appears, check the software
on the computer or the configuration for
connections.
