1.3.4 Prevention Hosts from Data Transfer Time-out

Generally, hosts abandon data transfer to peripherals when a peripheral is in the busy state for dozens of seconds continuously. To prevent hosts from this kind of time-out, the printer receives data very slowly, several bytes par minute, even the printer is in busy state. This slowdown starts when the rest of input buffer drops under several hundreds of bytes. Finally, the printer is in the busy state continuously when the input buffer is full.

1.3.5 Interface Selection

The EPSON Stylus COLOR 1520 has three types of interface available :Parallel, Serial, and optional interfaces. Each interface can be selected manually or automatically. Both modes are selected thorough the default setting mode.



Manual selection The interface selected through the default setting mode always prints out data from the host.



Automatic selection

When the printer is in this mode, the printer is initialized to the idle state when it is turned on. Then the interface that receives data first will print. When the host stops data transfer and the printer is in the stand-by state for the specific time, the printer returns to the idle state. As long as the host sends data or the printer interface is buy state, the selected interface remains active.

Interface State and Interface Selection

When the parallel interface is not selected, the interface goes into the busy state. When the serial interface is not selected, the interface sets the DTR signal MARK. When the printer is initialized or returned to the idle state, the parallel interface goes into the ready state and the serial interface sets the DTR signal SPACE. Caution that the interrupt signal such as the /INIT signal on the parallel interface is not effective while that interface is not selected.

Note)

1. Before the printer power is off, the printer executes the capping function.

2. When the micro adjust is performed at the TOF (Top Of Form position) for the ASF manual and tractor feed, the new setting is stored in the corresponding address in the EEPROM.

3. When the micro adjust is performed at the tear off position, the new setting is stored in the corresponding address in the EEPROM

CAUTION



The power switch is connected to the secondary side of the electrical circuit. Since it has a delay circuit, voltage is still applied for the specified period of time after the printer power is off.



As long as the printer is plugged in, voltage is applied to the primary side of the electrical circuit. Therefore be sure to unplug the printer before servicing or replacing the interface.
