iR5570 / iR6570
- As a rule, provide scheduled servicing every 250,000 prints.
- Check with the Service Book before setting out for a scheduled service visit, and take parts for which replacement
is expected.
- If the power plug is left connected for a long time in a place subject to dust, humidity, or oil smoke, a fire hazard
is a possibility (i.e., the dust collecting around the plug can absorb moisture, resulting in insulating failure). Be
sure to disconnect the power plug on a periodical basis, and wipe off the dust and dirt collecting around it.

1) Report to the person in charge, and check the general condition.
