Important!
When using a printer power supply other than the optional AC adaptor (PS48-
24A), be sure that the following cautions are observed.
• Use a power supply of DC 24 V ±5% and more than 2.0 A.
• Be careful about installing the printer in an area where there is noise. Take the
appropriate measures to protect against electrostatic AC line noise, etc.
