Cleaning the Print Heads and the Roller

Periodic inspection and cleaning of the orifice plates on the bottom of the print block ensures that the print nozzles are not clogged. A wizard guides you through the procedure, and adjusts components of the printer to enable you to perform it. This procedure takes about 20 minutes, and should be done at the beginning of the work day or before a big printing job.

To clean the print heads and the roller:
1.   Prepare—
•   90% isopropanol (IPA—isopropyl alcohol) or ethanol (ethyl alcohol)
•   disposable cleaning gloves
•   a supplied cleaning cloth or equivalent
•   a mirror
2.   Start the Head Cleaning wizard from the Options menu.
3.   Follow the instructions on the wizard screens, and select the confirmation check boxes.

4.   Click Next.

The printer prepares for you to clean the print heads.

5.   When the following screen appears, open the cover.

Warning: Hot Surface
The print head orifice plates (bottom surface) may be hot. Do not touch them with your bare hands, and proceed with caution.
6.   Place the mirror on the build tray.
7.   Put on the gloves.
Caution
Uncured printing material on the print heads might cause skin irritation. Use disposable cleaning gloves to protect your hands.
8.   Soak the cleaning cloth with alcohol.
9.   Clean the orifice plates, with a back-and-forth motion. Use the mirror to make sure that you have removed all of the residue material.

10.   Clean the entire roller surface, by rotating it as you clean.
Use this opportunity to clean the glass lens on the UV lamps using the supplied sanding sponge.
11.   When you have finished cleaning, select the confirmation check box in the wizard screen and click Next.
12.   Remove the cleaning materials from the printer and close the cover.
13.   Select the confirmation check boxes in the wizard screen and click Next.

The head-purge cycle begins. When the process is complete, click Done in the final wizard screen.
