2.2.2.5 EEPROM Control Circuit

Since EEPROM is a nonvolatile memory, it keeps information written if
the printer power is turned off. It stores such information as adjustment
values, factory values, and printer status values.

The EEPROM control circuit block diagram is as shown below:

Figure 2-22. EEPROM Circuit Block Diagram

EEPROM is connected to ASIC with 4 lines and each line has the following
function.

CS:

Chip selection signal

CK:

Data synchronism clock pulse

DI:

Data writing line (serial data) at power off.

DO:

Data reading line (serial data) at power on.

2.2.2.6 Sensor Circuit

The Stylus PHOTO 2000P has the following five sensors to detect printer’s
status.

PE Sensor

ASF Sensor

BCO (Black head cartridge) sensor

CCO (Color head cartridge) sensor

Head Thermistor sensor

Liner sensor

The block diagram for the sensor circuit is as shown below:
