1.3 Interface
This printer provides parallel interface and serial interface as standard.
1.3.1 Parallel Interface (Forward Channel)
[Transmission mode]
[Synchronization]
[Handshaking]
[Signal level]
[Adaptable connector]
BUSY signal is set high before setting either/ERROR low or PE high and held high until all these
signals return to their inactive state.
BUSY signal is at high level in the following cases.
During data entry (see Data transmission timing)
When input data buffer is full
During -INIT signal is at low level or during hardware initialization
During printer error (See /ERROR signal)
When the parallel interface is not selected
: 8 bit parallel, IEEE-1284 compatibility mode
: By STOPBE pulse
: BY BUSY and ACKLG signal
: TTL compatible level
: 57-30360 (amphenol) or equivalent
ERROR signal is at low level when the printer is in one of the following states.
Printer hardware error (fatal error)
Paper-out error
Paper-jam error
Ink-out error
PE signal is at high level during paper-out error.
Table 1-9 shows the signal and connector pin assignments for parallel interface(forward channel*1).
In case of these signals, twist pair line is used and returning side is connected to signal GND.
(*1): Forward channel is the mode when the ordinary data such as an order to print is sent
from the PC to the printer.

Following lists “Notes” when using Parallel Interface.
Note1) “
Return GND pin” in the table means twist pair return and is used for all control signals
except for Logic H,+5V, Chassis, GND and NC. In this twist pair return, returning side
is connected to GND (16, 33, 19-30 pin) for twist pair return. Also, these cables are shielded
wires and it is effective to connect to each chassis GND in the PC and printer for electrostatic
noise.
Note2)
Conditions for Interface are based on TTL level. Rise and fall time should be within 0.2µs.
Note3)
Note4)
Refer to the figure 1-9 for transmission timing of each signals.
Do not perform data transmission ignoring /ACK or BUSY signal. (Perform the data transmission
after confirming that /ACK and BUSY signals are Low.)
Note5)
It is possible to perform the printing test including interface circuit without using equipment
from outside when 8-bit data signal(20-27 pin) is set to appropriate word code and connect
them forcefully to /ACK and /STRB.

1.3.4 Prevention Hosts from Data Transfer Time-out
Generally, hosts abandon data transfer to peripher als when a peripheral is in the busy state f or dozens of
seconds continuously. To prevent hosts from this kind of time-out, the printer receives data very slowly,
several bytes per minute, even if the printer is in busy state. This slow down is started when the rest of the
input buffer becomes several hundr eds of bytes. Finally, the printer is in the busy state continuously when
the input buffer is full.
1.3.5 Interface Selection
The printer has 2 built-in interfaces; the parallel interface and serial interface. These interfaces are
selected automatically.
Automatic selection
In this automatic interface selection mode, the printer is initialized to the idle state scanning which
interface receives data when it is powered on. Then the interface is that receives data first is
selected. When the host stops data transfer and the printer is in the stand-by state for the
seconds, the printer is returned to the idle state. As long as the host sends data or the printer
interface is busy state, the selected interface is let as it is.
Interface state and interface selection
When the parallel interface is not selected, the interface got 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 got into the ready state, 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.

[Maintenance Error Reset Procedure]
You can reset the maintenance error by pressing the cleaning button after you enter the particular setting
mode(Refer to table 1-18, 19). There are no function which can be reset the all address in EEPROM on
the EPSON Stylus Photo. Following are detail procedure of maintenance error reset operation
[Step 1] By pushing Load/Eject and Cleaning buttons at the same time, turn on the power switch.
(By operating this performance, the LED for paper out starts blinking.(5 seconds only) )
[Step 2] Push the Load/Eject button for 10 seconds while the LED for Paper Out is blinking.
Note)
If the printer accepts this function correctly, it returns to the standby mode after the
Maintenance LEDs (both black and CMYcm) blink for 1 second.
Following shows the lists that will be cleared by this performance.
1. Clear the value of Ink Counter
2. Clear Time IC
3. Initialization of I/F selection (returns to AUTO)
WARNING
Since EPSON Stylus Photo does not have “All Clear function” for EEPROM like other printers, do
not perform this operation except for the purpose of the maintenance error reset.
Be sure to replace a waste ink pad in the printer enclosure with a new one after you perform
[Maintenance error reset procedure].
If the waste ink pad is replaced regardless of maintenance error, perform this operation.
