3. If the substrate type that is loaded is acceptable for printhead alignment, the printer performs the alignment and prints an alignment pattern. NOTE: Make sure the printer window is closed during printhead alignment. 4. The process takes about 5 minutes. Wait until the front panel shows that the process is complete before using the printer. Scan errors during alignment If the alignment process fails, a Scanning problems message appears on the front panel. This indicates that the alignment was not completed successfully. Therefore, the printheads are not aligned and the alignment should be repeated before printing. The problem might be because of one of the following scenarios: ● The type of substrate used in the printhead alignment process was not acceptable. Repeat the alignment process using one of the recommended substrate types. ● The printheads are not clean. Clean the printheads. See Clean the printheads on page 73. ● The printer window was open during the printhead alignment process. Repeat the alignment process with the printer window closed. If the problem persists after following the recommended remedies, try replacing all of the printheads. If the problem persists after replacing the printheads, a failure in the scanning system may exist. Troubleshoot ink ENWW Align the printheads 75
