Cleaning the Print Heads, Roller and Wiper
Regular inspection and cleaning of the orifice plates on the bottom of the print heads prevents print nozzles from clogging. Cleaning the roller and wiper are also important for maintaining quality printing. A wizard adjusts printer components to enable access to these key areas, and it guides you through the cleaning procedure. To maintain the printer in optimum condition, run the wizard after every print job, when you remove the model from the build tray. This procedure takes about 20 minutes.

90% isopropanol (IPA—isopropyl alcohol) or ethanol (ethyl alcohol) |

disposable cleaning gloves
