1.6.2 Electrical Characteristics
Note:
The current consumption is as follows when a receipt is printed in low temperature. Take in consideration
if a power supply other than the Epson specified one is used or the print pattern is different.
❏ The values in the table above are measured in the following conditions, but are just for your
reference.
❏ The Epson original power supply PS-180 can print within the print duty above.
Supply voltage: +24 VDC
± 10% (optional power supply: EPSON PS-180)
Ripple voltage: 300 mVpp or less
(only when the printer is used with the MICR reader)
Current consumption (at
24V except for drawer
kickout driving):
Slip: Operating:
Mean: Approximately 1.7A
(Character font A α-N, all columns printing)
