Intermec EasyCoder PC4—Service Manual 1
1 Models and Options
is chapter provides information on the various models of the EasyCoder
PC4 and contains specifications and physical measures.
2 Intermec EasyCoder PC4—Service Manual
Chapter 1—Models and Options
1.1 Models
ere are two main models of the EasyCoder PC4; one dedicated direct
thermal (DT) model and one dual-capable direct thermal/thermal transfer
(TTR) model. Both models are based on a common double clam-shell
mechanical platform and have the same type of electronics, so except from
the fact that the direct thermal model has no transfer ribbon mechanism,
there are very few differences.
Both models are available with two different printheads; one with a density
of 203.2 dots per inch (8 dots per mm) and a maximum print width of 4.1
inches (104 mm), and another with a density of 300 dots per inch (11.81
dots per mm) and a maximum print width of 4.02 inches (102.2 mm).
Since there is no need to open the top cover in the DT model, the top
cover locks are cut off in flush with the bottom of the print frame.
e machine label, which provides information on model, part number,
serial number, etc. is attached to the bottom of the base frame.
e EasyCoder PC4 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).
