Electrically Erasable Programmable Read-Only Memory — a chip that stores the printer's configuration data, calibration values, and usage counters.
In-Depth Explanation
The EEPROM retains data even when the printer is powered off. It stores critical information including printhead alignment data, color calibration values, ink usage counters, and service history. Error 0x00C90001 indicates an EEPROM configuration error, which can cause the printer to lose its settings or fail to boot. EEPROM corruption sometimes requires a service technician to reprogram the chip.
