If the Printer Status dialog indicates a print head needs changing, follow the steps below.
- Open the printer top cover.
- If the piston is not already lowered some distance into the build box, lower it now by selecting LOWER PISTON. The piston will lower a short distance. To lower it further, select LOWER PISTON again.
- On the printer’s LCD menu, select PRINT HEAD then CHANGE PRINT HEAD. The Printer moves the Fast Axis out over the Build Bed.
- Open the carriage cover by releasing the latch.
- Lift print head out of its slot and properly recycle or dispose of the spent cartridge.
- Get an alcohol crush-tube swab. Snap it to break the glass inside, and squeeze the tube to saturate the swab. Alternately, you can use Isopropyl Alcohol on a non-shed swab.
- Wipe off all the pogo pins for (both) printhead(s) (inside the carriage) with the alcohol swab. Use additional swabs if needed.
- Wet a paper towel with distilled water and wipe the underside of the Carriage. Keep wiping until the towel picks up no more debris or ink.
- Dry with a clean paper towel.
- Allow several minutes to ensure all alcohol has evaporated off of the pogo pins before proceeding to next step.
- Remove the new printhead from its packaging. Be sure to pull the tape tab off of the new printhead.
- Insert the new printhead. Press down firmly on the top of the printhead, at the same side as the pogo pins, to securely fit the printhead into its slot.
- Close the carriage cover by pressing down until you hear it click shut. Be sure the latch is engaged.
- Close the printer top cover. Select CONTINUE on the LCD.
- The fast axis reparks.
- 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.
- 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.
