Effective troubleshooting follows a logical sequence:

1. Identify the symptom
2. Print the appropriate test page
3. Analyze the results
4. Apply the solution
5. Verify with another test

Sequential Testing

For complex issues, use multiple tests:

1. Start with nozzle check
2. Progress to color test
3. Verify with alignment test
4. Confirm with full-page print
