What is the Epson EM-900CN Adjustment Program?

The Epson EM-900CN Adjustment Program is a service tool developed by Epson for maintenance and calibration purposes. This software is commonly used by technicians and advanced users to reset various counters and diagnose issues that may affect printer performance. The program is particularly useful in cases where the printer stops working due to an exceeded waste ink counter or printhead misalignment.

Key Features

1. Waste Ink Pad Counter Reset: Over time, Epson printers accumulate waste ink, leading to an error that prevents further printing. The adjustment program resets the waste ink pad counter, allowing the printer to function normally.
2. EEPROM Initialization: The program enables users to reset the printer’s EEPROM (Electrically Erasable Programmable Read-Only Memory), which stores important printer data and settings.
3. Head Cleaning and Alignment: This feature helps users clean and align the printhead to improve print quality and prevent nozzle blockages.
4. BID Adjustment: Ensures proper Bi-Directional Printing for optimal performance and sharp print outputs.
5. Printer Port Checking: The software can diagnose issues related to the communication between the printer and the computer.
6. Ink Charge: Allows the refilling and resetting of ink levels, preventing false low-ink warnings.
7. Paper Feed Adjustment: Helps resolve paper feeding issues by recalibrating the paper transport mechanism.
8. Nozzle Check: Detects and displays clogged nozzles, allowing users to clean specific ink nozzles efficiently.
9. Carriage Motor Maintenance: Diagnoses potential issues with the carriage motor, ensuring smooth movement during printing operations.

• Ensure the ink cartridges are properly installed and have sufficient ink.

Best Practices for Using the Adjustment Program

1. Use Only When Necessary: Frequent resetting of counters and EEPROM may lead to firmware issues. Use the program only when maintenance is required.
2. Backup Printer Settings: Before making adjustments, take note of important printer settings in case you need to restore them.
3. Regularly Clean the Printer: Instead of relying solely on software resets, perform physical maintenance like cleaning the waste ink pad, nozzles, and paper feed rollers.
4. Keep Your Printer Drivers Updated: Ensure your printer driver and firmware are always updated to prevent compatibility issues.
5. Use High-Quality Ink and Paper: Poor-quality consumables can lead to frequent maintenance needs, so invest in genuine or compatible high-grade supplies.
