Parallel - Epson Stylus Pro 5000 Service Manual

Stylus Pro 5000
PARALLEL INTERFACE
Table 1-10. Compatibility Mode
Item
Transmission mode 8-bit parallel, IEEE-1284 compatibility mode
Synchronization By STROBE pulse
Handshaking By BUSY and ACKNLG signal
Logic Level TTL compatible level (IEEE-1284 Level 1
device)
Adaptable connector 57-30360 (Amphenol) or equivalent
Note 1: Use a twisted-pair cable.
Note 2: The BUSY signal is set high when the /ERROR signal is low or
the PE signal is high. The BUSY signal remains high until all
these signals return to their normal state.
The BUSY signal is high:

During data entry
When the input data buffer is full



When the /INT signal is low, or during hardware initialization
During a printer error (See Error Conditions)



When the parallel interface is not selected
The ERROR signal is low when there is a:
Printer hardware error (fatal error)



Paper out error

Paper jam error

Ink out error
Note: The PE signal is high during a paper-out error.

Data requests When the printer receives the hexadecimal
values 00H or 04H, the printer responds in the
following manner:
00H: The printer enters reverse channel
mode, allowing data to be sent to the
host.
04H: The printer sends the device ID to the
host; the device ID consists of the
following strings:
Note: [00H] denotes a hexadecimal value of
zero. The model value depends on the
EEPROM setting.
