Clean the electronics box filters (quarterly)
Electronics box fan filters keep dust and other debris from entering the air-cooled area of the
electronics box. If the filter becomes clogged, the electronics may overheat, causing performance
errors. There are two air intake fans to clean. One is located near the power switch on the user-end of
the printer (input side). The other is located in the middle area under the printer chassis where the
power cord attaches on the user-end.
1. From the control panel (System page > Tools > User Cleaning and Maintenance), select
Clean Electronics Box Filters.
2. Press Proceed to continue.
3. Vacuum the dust and debris from the front of the fan on the input-side of the electronics box
