Printhead Alignment Errors C4704034 The printer runs the printhead alignment procedure every time you load, replace or even reseat a printhead. The routine is also run when media is loaded that is of a different media type from that previously loaded, or after powering on the printer with no media loaded. The message "Printhead alignment error" is displayed when the alignment procedure has failed or the printer detects a fault that stops the procedure from completing. The alignment procedure is the first time that printheads print after installation, so an initial printing problem may be reported as an alignment error. Most alignment errors are due to: Problems with the media. Poor printhead start-up. Alignment difficulties with the printheads or other printhead malfunction. You will see the message "Check ink system / Ignore" (see page 74, If You Have Problems Reseating a Printhead). If you choose to check the ink systems you will be given the opportunity to check the printheads that may have caused the problem. Media Problems 1 Check that the media you are using is clean and has not been printed on. It should be white and opaque. Colored or clear films, media with insufficient opacity, or extremely thick or thin media may be causing the Printhead Alignment Error message. 64
