1.10 Electrical Characteristics

1) Supply voltage: +24 VDC ± 7%

(optional power supply: EPSON PS-170, PS-180)

2) Current consumption (at 24V in room temperature):

Mean: Approximately 1.7 A (in single-color print)

(Character font A, alphanumeric, capital letters, 36-character

rolling pattern, full column printing)

Mean: Approximately 1.7 A (in two-color print)

(Character font A, alphanumeric, capital letters, 36-character

rolling pattern, full column printing, changing the print color each

line)

Peak: Approximately 7.7 A or less (with full-dot printing)

Mean: Approximately 1 A (in single-color print)

(Character font A, alphanumeric, capital letters, 36-character

rolling pattern, full column printing)

NOTE: The four-part energizing mode can be selected with the

memory switch. If the power supply is the power-savings

type with lower capacity, the printer can print with the

four-part energizing mode set. Four-part energizing

reduces the power supply load by energizing of the print

head in four parts.

Mean: Approximately 0.1 A

NOTE: Maximum 1 A for drawer kick-out driving.
