WARNING

Installation 

Do not set up the printer in a dusty environment. If 
dust collects inside the printer, it may cause fire or 
electric shocks or problems with correct operation. 
 
Be sure to connect the ground. If the ground 
connection is not secure, you run a high risk of 
receiving a serious electric shock, and problems with 
correct operation may also occur.

Do not bend the cords excessively or fasten them 
too hard with staples or anything similar to secure 
cords, otherwise there is the danger that fire or 
electric shocks could occur. 

Printing 

If a foreign object gets inside the printer, immediately 
turn off the power switch and disconnect the power 
cord, and arrange for a service call to resolve. 
If you continue to use the printer while there is a 
foreign object inside, it may result in fire or electric 
shocks or problems with correct operation. 

Do not allow water or oil to get onto the printer, 
otherwise it may cause fire or electric shocks or 
problems with correct operation. 
If any liquids get onto the printer, immediately turn 
off the power switch and disconnect the power cord, 
and arrange for a service call to resolve.

Do not use the printer when smoke or a bad odor 
coming from the printer, otherwise it may cause fire 
or electric shocks or problems with correct 
operation. 
Immediately turn off the power switch and 
disconnect the power cord, and arrange for a 
service call to resolve.

Maintenance 

Do not put your hands in the ink cartridge slot, otherwise the needle inside the slot may cause injury. 

 CAUTION 

Environmental requirements 

Use the printer in an area which is free from 
sources of strong electrical noise such as electrical 
line noise or static electric noise. 
Sources of strong electrical noise may cause 
problems with correct operation. 

Any fluctuations in the power supply voltage should 
be within ±10% of the rated voltage for the printer. 
Voltage fluctuations which are greater than this 
may cause problems with correct operation. 

The power supply capacity should be greater than 
the requirements for the printer’s power 
consumption. 
Insufficient power supply capacity may cause 
problems with correct operation. 
 

The ambient temperature should be within the 
range of 15

°

C to 30

°

C during use. 

Temperatures which are lower or higher than this 
may cause problems with correct operation. 

The relative humidity should be within the range of 
20% to 85% during use, and no dew formation 
should occur in any devices. 
Excessively dry or humid environments and dew 
formation may cause problems with correct 
operation. 

Use the printer in a place which is adequately 
ventilated. 
A slight odor is generated when the printed articles 
are being fixed by heat. 

In the event of an electrical storm, turn off the power 
and disconnect the power cord from the wall outlet. 
Lightning may cause problems with correct 
operation.
