Cleaning and Replacing the Wiper

A rubber wiper removes excess material from the print heads after the purge sequence. This is done automatically before each print job, and performed manually during maintenance tasks. You should clean the wiper and surrounding area at least once a week. If the wiper is damaged or worn, replace it.

To inspect and clean the wiper:
1.   Prepare—
•   90% isopropanol (IPA—isopropyl alcohol) or ethanol (ethyl alcohol)
•   disposable cleaning gloves
•   a supplied cleaning cloth or equivalent
•   a spare wiper
2.   Start the Wiper Cleaning wizard from the Options menu.

3.   In the opening wizard screen, click Next.
4.   Make sure that the build tray is empty, and close the printer cover.

Confirm this in the wizard screen, and click Next.

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

6.   Put on the cleaning gloves.
7.   Using a generous amount of alcohol on the cleaning cloth, remove any material remaining on the wiper and the surrounding area.
8.   Remove any pieces of waste material collected in the purge unit.
9.   Inspect the wiper.

If the wiper is scratched, torn or worn, or if you cannot clean it completely, replace it:

a.  Grasp it and pull it up and out of its bracket.

b.  Insert the new wiper blade, making sure that it is straight and secured well on both sides.

10.   In the wizard screen, confirm that the wiper blade is clean, and click Next.
11.   Remove all tools and cleaning materials from the printer, and close the cover.
12.   Confirm this in the wizard screen, and click Next.

13.   In the final sceen, click Done to close the wizard.
