1.3.1 Hardware Interfaces
This section describes the Stylus 1500 interfaces. The printer is standard-equipped with a parallel interface.
1.3.1.1 Parallel Interface Forward Channel
Transmission mode: 8 bit parallel, IEEE-P1284 compatibility mode Synchronization: Handshaking: BUSY and Signal level: TTL-compatible level (IEEE-P1284 Level 1 device) Adaptable connector: 57-30360 (Amphenol or equivalent)
STROBE pulse
ACKNLG signal
The BUSY signal is set HIGH before either
ERROR is set LOW or PE is set HIGH, and BUSY is held HIGH
until all these signals return to the inactive state. The BUSY signal goes HIGH in the following cases:
o During data entry (See Figure 1-4 below.) o When the input data buffer is full. o When the o During a printer error condition (See the
INIT signal is LOW or during hardware initialization.
ERROR signal description below.) o During self-test printing. o In default setting mode. o When the parallel interface is not selected.
ERROR signal is LOW when the printer is in one of the following conditions:
The
o Printer hardware error (fatal error). o Paper-out error. o Release lever operation error.
The PE signal is HIGH during a paper-out error.

I/O Description
Reading of data is performed at the falling edge of this pulse.
Signals DATA0 - DATA7 represent data bits 0 to 7, respectively. Each signal is HIGH when
I
the data is logical 1 and LOW when the data is logical 0.
This signal is a negative pulse indicating that
O
the printer can accept more data. When this signal is HIGH, the printer cannot

receive data. When this signal is HIGH, the printer detects a
paper-out error. This signal is always HIGH when the printer is
powered on.
The falling edge of a negative pulse or a LOW signal on this line causes the printer to
initialize. A 50 µs (minimum) pulse is necessary.

1.4 OPERATIONS
This section describes the controls, settings, and adjustments used to operate the Stylus 1500.
1.4.1 Control Panel
The control panel for this printer is in the center of the upper case. The panel has 1 lock-type and 6 non-lock-type pushbuttons, and 10 LED indicators for easy operation of the various print functions.
Figure 1-5. Control Panel Appearance
1.4.1.1 Buttons Power
This button turns the printer on or off.
ATTENTION
The power button controls the secondary power supply circuit. Therefore, the primary circuit is hot after power off. Do not connect the interface cable even if the printer power is off while the AC inlet is connected. Otherwise, the circuit board or interface may be damaged.
Pause
This button alternates between printing and non-printing states when there is data in the print buffer. In the pause state, printing stops but communication with the I/F does not stop. Therefore, even in the pause state, the printer receives data from the host until the input data buffer is full.
o
Pressing the Pause button while holding down the Alt button resets the printer.
Alt
This button is usually used with another button.
o Holding down Alt for 3 seconds moves the printer carriage to the ink cartridge
installation position. Pressing Alt again returns the carriage to the home position.
LF/FF
This button feeds one line or a page.
o Pressing LF/FF while holding down Alt starts the black printhead cleaning cycle.
Economy/Condensed
This button selects economy or condensed printing mode.

1.4.5 Printer Adjustment Mode
The Stylus 1500 allows the user to adjust the printing direction and head gap without a special program. The following list shows the adjustments for this printer in order:
Pattern 1 Uni-D adjustment at 400 cps Pattern 2 Bi-D adjustment at 100 cps Pattern 3 Bi-D adjustment at 200 cps Pattern 4 Bi-D adjustment at 400 cps Pattern 5 Head gap adjustment (for the black and color printheads in the carriage movement direction
at 100 cps)
Pattern 6 Head gap adjustment (for the black and color printheads in the carriage movement direction
at 200 cps)
Pattern 7 Headgap adjustment (for the black and color printheads in the paper feed direction)*
* These adjustments are performed only when the color upgrade kit is installed in the printer.
Adjustment Method
Use the following steps to perform the adjustments:
1. Hold down the Pause button while turning on the power. The printer enters adjustment mode. “Using this mode” and the pattern 1 are printed.
*
*
2. Select the number of the most closely aligned columns by pressing the Alt button. The black Ink Out, color Ink Out, and Paper Out LEDs show the line number currently selected. This
selection advances once each time the Alt button is pressed, and the three LEDs change their combination of On /Off / Blinking to indicate the selection.
3. Specify the selected number by pressing the Pause button. The selected number is set, and the next pattern is printed.

1.4.6 Printer Initialization
This printer has three initialization types: hardware, software, and panel.
1. Hardware Initialization
Hardware initialization is performed by turning on the printer or sending the INIT signal to the parallel interface. The following functions are executed:
o The printer mechanism is initialized.
o The input data buffer is cleared.
o Downloaded character definitions are cleared.
o The print buffer is cleared.
o Default values are set.
2. Software Initialization
Software initialization is performed when the printer receives the ESC @ command. The following functions are executed:
o The print buffer is cleared.
o Default values are set.
Note: Thelast panel settings are kept after software initialization.
3. Panel Initialization
Panel initialization is performed by pressing the Load/Eject button while holding down the Alt button. The following functions are executed:
o The input data buffer is cleared.
o The print buffer is cleared.
o Default values are set.
Note:
The last panel settings are kept after panel initialization.
1.4.7 Monochrome Printing Mode
This printer has a monochrome printing function that allows printing to continue with black ink when the color ink cartridge is out or the color upgrade kit is not installed. This function is selected by the printer driver setting. To enter monochrome printing mode, turn the Power button off and back on again.
Notes: 1. Once the printer has entered this function, print data must be resent.
2. The color select command (
ESC r
)isignored.
