The BUSY signal is set HIGH before setting either /ERROR LOW or PE HIGH, and held HIGH until all
these signals return to an inactive state. The BUSY signal is HIGH in the following cases:
During data entry.
When the input data buffer is full.
While /INIT signal is at a LOW level or during hardware initialization.
During a printer error condition (See the /ERROR signal).
During test printing.
When the printer is in default setting mode.
When the parallel interface is not selected.

1.5.5 Preventing Hosts from Data Transfer Timeout
Generally, hosts abandon data transfer to peripherals when a peripheral is BUSY continuously for dozens
of seconds. To prevent this kind of timeout, the printer receives data very slowly, several bytes per minute,
even the printer is in a busy state. This slowdown starts when the remainder of the input buffer drops
under several hundred bytes. Finally, the printer is BUSY continuously when the input buffer is full.
1.5.6 Interface Selection
The Stylus COLOR 800 can have three types of interfaces: parallel, serial, and optional Type-B. Each
interface can be selected manually or automatically. Both modes are selected through default setting
mode.
Manual Selection
One of 3 interfaces selected through the default setting mode. The selected interface is fixed.
Automatic Selection
Automatic interface selection is enabled in default setting mode. In automatic interface selection mode,
the printer is initialized to the idle state when it is powered on (*1) scanning which interface is to receive
data. Then the interface that receives data first is selected. When the host stops data transfer and the
printer is in the standby state for a number of seconds, the printer returns to the idle state. As long as the
host sends data or the printer interface is busy state, the selected interface is left as it is.
*1: No interface is selected in this state.
Interface Selection and Interface State
When an interface other than the parallel interface is selected, the parallel interface goes into the
BUSY state.
When the interface other than serial interface is selected, the serial interface sets the DTR signal
MARK.
When the printer is initialized and returned to idle state, the parallel interface goes into ready state
and the serial interface sets the DTR signal SPACE.
Note: An interrupt signal such as the INIT on the parallel interface is ignored while that interface is not
selected.

This printer has 3 printing modes:
Default mode

Each mode is selected according to printer condition, as described below.
Default Mode
Color mode is selected automatically when both black and color cartridges are installed
and no ink end error has occurred. When color ink ends, the printer can go into
monochrome print mode. It is, however, switched by turning the printer off and back on
again, or by sending the INIT signal.
Default mode is selected when the printer is initialized.
Color Mode
The printer prints normally, based on whether print data is black or color.
Can be selected through the printer driver.
Monochrome Mode
The printer prints all data in black only. Color data selection (

1.7.1 C202 MAIN Board
The C202 MAIN board controls various printer operations. It consists of an HD6432653 CPU (128-pin,
19.66 MHz), ASIC E05B33CB (208-pin, 19.66 MHz), 8M-bit-type PROM (42-pin, including CG data) or
8M-bit-type PROM + 8M-bit-type CG (NLSP version only), 4M-bit-type DRAM, EEPROM, and several
drivers. Because this board is installed into the slot in the rear cover of the printer using 2 screws and
several connectors, it is easily removed and installed.
