1 Models and Options

is chapter provides information on the various models of the EasyCoder

PC41 and contains speciﬁcations and physical measures.

Chapter 1—Models and Options

1.1 Models

e EasyCoder PC41 uses both Direct ermal (DT) and ermal Trans-

fer (TTR) printing technology. It employs a printhead with a printing den-

sity of 203.2 dots per inch (8 dots per mm) and a maximum print width of

4.1 inches (104 mm).

e machine label, which provides information on model, part number,

serial number, etc. is attached to the bottom of the base frame.

e EasyCoder PC41 has a separate power supply unit that delivers 24

VDC to the printer's main board, where it is transformed to the various

voltages required by the printhead, motor, and logics (see Chapter 8.1).

e power supply unit (PSU) accepts 100 to 240 VAC/50 to 60 Hz. e

power supply has a standard 2-pin input voltage socket, so various types of

power cords can be used according to local voltages and standards.

e power supply has a ﬁxed 1.5 m (4.9 ft) long cable that is connected to

the printer’s rear plate.
