12.3.3 Scheduled Servicing Basic Procedures

iR2270 / iR2870 / iR3570 / iR4570 / iR3530
- 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.
<Work Procedure>
1) Report to the person in change, and have an understanding of the situation.
2) Record the counter reading, and check the faulty prints.
3) Check the following items, and adjust or clean the parts as needed.
