What should I do if I see incomplete or missing lines in my printed output?

Incomplete or missing lines typically indicate a printhead issue. First, run the Troubleshooting Procedure by selecting Ink > Troubleshooting from the front panel menu. The printer will check printhead alignment, print diagnostic patterns, and may attempt to clean the printheads if necessary. The troubleshooting routine will guide you through corrective actions step-by-step. (Page 80)
