1.2.3.1 Adjust Lever Setting

The adjustment lever located on the right side (dark blue) under the printer cover needs to be set to the proper position according to the paper you print. (Refer to the Table 1-7.) Also, if there is any dirt caused by friction on the way or wrinkled paper, this can be prevented by changing the lever position to rear position (marked with “+”) in spite of paper types.

Table 1-7. Adjust Lever Setting

	Lever Position	Clearance between head and platen
	Plus Position	1.04 mm
	Zero Position	1.74 mm (+0.7 mm)

NOTE: Return the adjust lever to the zero position, which is normal position, after you finish printing on all media. Leaving the lever in the plus position may cause the printed image to have gaps on other media.

This printer provides parallel interface as standard.

8 bit parallel, IEEE-1284 compatibility mode By /STOPBE pulse

BY BUSY and /ACKLG signal TTL compatible level

[Adaptable connector]57-30360 (amphenol) or equivalent

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)

/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.

See Table 1-10 in the following page which 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.

Revision A

The following are the points to note when using the parallel Interface.

NOTE 1:“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.

NOTE 2:Conditions for Interface are based on TTL level. Rise and fall time should be within 0.2μs.

NOTE 3:Refer to Figure 1-9 for transmission timing of each signals.

NOTE 4:Do not perform data transmission ignoring /ACK or BUSY signal. (Perform the data transmission after confirming that / ACK and BUSY signals are Low.)

NOTE 5: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.

NOTE: A low logic level on the Logic H signal is 2.0V or less when the printer is powered off and this signal is equal or exceeding 3.0V when the printer is powered on. The receiver shall provide an impedance equivalent to 7.5K ohm to ground.

1.3.2.1 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 this kind of time-out, the printer receives data very slowly, several bytes per minute, even if the printer is in busy state. This showdown is started when the rest of the input buffer becomes several hundreds of bytes. Finally, the printer is in the busy state continuously when the input buffer is full.

1.3.2.2 Auto Interface Selection (for Stylus Color 640, 740)

Manual Selection:

One of two interfaces can be selected by the default setting mode.

Automatic Selection:

The automatic interface selection is enabled by the default setting mode. 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 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.

Following explains conditions of other interfaces when a particular interface is selected.

When the parallel interface is not selected, the interface gets into BUSY state. At this time, LH signal is set to “L”. That means blocking power supply and no responds from 1284. Therefore, it is necessary for the host, which requires Reverse transfer, to check LH 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, Parallel interface becomes the ready condition and DTR of serial interface becomes SPACE (Low) condition and reset off-line bit of Main Status Register (MNSTS)to, option interface.
