1.4 OPERATION

This section describes the initialization procedures, interface selection
procedures, control panel operation, and error conditions of the EPSON
Stylus Pro 5000.

INITIALIZATION

There are three ways to initialize the Stylus Pro 5000:
Hardware initialization:


When the power is turned on or a cold-reset command is sent to the
printer (remote RS command), the printer does the following:
1. Initializes the printer mechanism
2. Clears the input data buffer
3. Clears the print buffer
4. Restores the default values

Software initialization:
When the printer receives an ESC@ command, it does the following:
1. Clears the print buffer
2. Restores the default values
Control panel (operator) initialization:


When the Reset button is pressed or the printer receives an /INT
signal (negative pulse) from the parallel interface, the printer does the
following:
1. Caps the print head
2. Ejects the paper
3. Clears the input data buffer
4. Clears the print buffer
5. Resets the default values

INITIALIZATION DEFAULT VALUES

When the printer is initialized, the control panel settings, default settings,
and settings saved in the driver will be set to their default values. The
following items are also restored to their initial values:
1. Top of form setting
2. Line spacing:
3. Right margin position:
4. Left margin position:
5. Word pitch:
6. Printing mode:

INTERFACE SELECTION

The printer has three built-in interfaces: parallel, serial, and Type-B (an
optional interface requiring an interface card). These interfaces are
selected automatically, or manually through the control panel (see section
1.5).
Manual Selection:


Select the desired interface through the default setting mode,
described below under Maintenance Mode (Level 1).

Automatic Selection:
Automatic interface selection is enabled by the default setting mode,
described below under Maintenance Mode (Level 1). When the
automatic selection is active, the printer passively scans all interfaces.
The interface that receives data first is selected as the active interface.
When the host stops sending data and the printer has been in a
standby state for 10 seconds, the printer returns to an idle state.
Otherwise, the interface remains active.
