1.6 Printer Initialization

Stylus COLOR 440, 640, and 740 have three kinds of initialization
methods, as described below:
Power-on initialization
Power-on initialization occurs when you turn the printer on, or when the
printer receives the cold reset command (remote RS command).
Power-on initialization performs the following actions:
(a) Initializes the printer mechanism.
(b) Clears the input data buffer.
(c) Clears the print buffer.
(d) Sets the default values.
Operator initialization
Operator initialization occurs when you turn the printer on less than 10
seconds after it was turned off, or when the printer receives the INIT
signal (negative pulse) from the parallel interface. Operator initialization
performs the following actions:
(a) Caps the printhead.
(b) Ejects the paper.
(c) Clears the input data buffer.
(d) Clears the print buffer.
(e) Sets the default values.
Software initialization
Software initialization occurs when the printer receives the ESC @
command. Software initialization performs the following actions:
(a) Clears the print buffer.
(b) Sets the default values.
