- As a rule, perform scheduled servicing every 120,000 prints.
- Before setting out on a scheduled visit, check with the Service Book, and take parts for which replacement is expected.
- If the power plug is exposed to dust, humidity, or oily smoke, the resulting buildup can prove to be a fire hazard. (The buildup of dust, for instance, can absorb
moisture and suffer insulating failure.)
Be sure to disconnect the power plug on a periodical basis, and remove any buildup of dust and dirt with a dry cloth.
