If the Printer Status dialog indicates a print head needs changing, follow the steps below.

  1. Open the printer top cover.

  3. On the printer’s LCD menu, select PRINT HEAD then CHANGE PRINT HEAD. The Printer moves the Fast Axis out over the Build Bed.

  3. If the HP11 printhead was replaced, it will need to be purged of its black ink before printing a part. You can select PURGE now, otherwise the printer will perform a purge the next time you start a build.
  4. In the 260C/260Plus/460Plus, the printheads will need to be realigned. This will be done via an automatic Alignment Print next time you start a build.
