Maintaining and Cleaning the Printer

There is no customer maintenance required for the EFP9800 printer. However, you may occasionally clean the cabinet as needed to remove dust and finger marks. Use any household cleaner designed for plastics, but test it first on a small, unseen area. The cabinet finish and materials are durable and are resistant to cleaning solutions, lubricants, fuels, cooking oils, and ultraviolet light.

If the receipt paper bucket is dirty, wipe it with a clean, damp cloth.

Caution

Do not spray or try to clean the printhead or the inside of the printer with any kind of cleaner as this may damage the printhead or the electronics.
