Maintaining the printer

3Remove all photodevelopers and toner cartridges.

Warning: Exposing the photodevelopers to light for prolonged periods of time can damage it. Do not expose the photodevelopers to light for more than ten minutes. Fingerprints can affect the performance of the photodevelopers. Avoid touching the photodevelopers anywhere except the handles.

Warning: The toner inside the toner cartridges can soil clothing. Do not clean clothing soiled with toner in hot water; this permanently adheres the toner to the clothing. Use cold water to remove toner that has soiled clothing.

4Wipe the glass lenses of all four LED heads with a clean, dry cloth or tissue paper.
