1.1 FEATURES
The Stylus Color IIs printer is a color ink jet dot matrix printer that comes with a 64-nozzle black printhead
and a 60-nozzle CMY color printhead, either of which can be installed in the printer. The Stylus 820 version
of the same printer comes standard with only the 64-nozzle black printhead; however, the CMY color
printhead can be purchased as an optional upgrade. Whenever this manual mentions the Stylus Color IIs, its

1.3 INTERFACE SPECIFICATIONS
The Stylus Color IIs is standard-equipped with an 8-bit parallel and serial interface.
1.3.1 Parallel Interface Specifications
Data format: 8-bit parallel
Synchronization: By STROBE pulse synchronization
Handshaking: By BUSY and ACKNLG signals
Signal level: TTL compatible level
Adaptable connector: 36-pin 57-30360 (Amphenol) or equivalent
Data transmission timing: See Figure 1-6.
Note:
Transition time (rise time and fall time) of every input signal must be less than 0.2 µs.
The Busy signal is active (HIGH) under the following conditions:
❏During data reception (See Figure 1-6.)
❏When the input buffer is full
❏When the INIT input signal is active
❏During initialization
❏When the ERROR or PE signal is active
❏During the self-test mode
❏During the demonstration mode
❏During the default setting mode
❏When a fatal error occurs
The ERROR signal is active (LOW) under the following conditions:
❏When a paper-out error occurs
❏When a no ink cartridge error occurs
❏When a fatal error occurs
The PE signal is active (HIGH) under the following conditions:
❏When a paper-out error occurs

Table 1-10 shows the connector pin assignments and signal functions of the 8-bit parallel interface.
Table 1-10. Signal and Connector Pin Assignments for Parallel Interface
Pin No. Signal Name I/O* Description
1STROBE I
The STROBE pulse is used to read data from the host
computer. The pulse width must be 0.5 µs or more. Normally,
it is HIGH, and data is latched with the rising edge of this
signal.
2-9 DATA 1-8 I
DATA 1-8 are parallel data bits. When one of these signals is
HIGH, the data bit is 1; when LOW, the data bit is 0. The
most significant bit (MSB) is DATA 8. The signal state must
be maintained for 0.5 µs on either side of the STROBE
signal’s active edge.
10 ACKNLG O
ACKNLG is an acknowledge pulse with a width of
approximately 10 µs. This signal goes LOW upon the
completion of data reception to indicate that the printer is
ready to receive further data.
11 BUSY O The BUSY signal informs the host computer of the printer’s status. When this signal is HIGH, the printer cannot accept
any more data.
12 PE O This signal indicates whether paper is available in the printer
or not. A HIGH level indicates no paper.
13 SLCT O Pulled up to +5 V through a 1.0 KΩresistor in the printer.
14 AFXT I
If this signal is set to LOW, the printer automatically performs
one line feed upon receipt of a CR (carriage return) code. The
status of this signal is checked only at power on and
initialization.
31 INIT I If this signal goes LOW, the printer is initialized. The pulse
width of this signal must be 50 µs or more.
32 ERROR O This signal goes LOW if the printer has a fatal error or runs
out of paper.
35 +5 V — Pulled up to +5 V through 1.0 KΩresistor in the printer.
17 CHASSIS — Chassis ground.
16 GND — Signal ground.
19-30 — — —
33,36 — — Not used.
