3.2 Parts for Maintenance and Repair
3.2.1 Replacement interval for parts with a limited life
Some of the parts in this printer have a limited life, shorter than that of the whole machine. These parts must
be replaced periodically.
The table below shows the interval at which these parts should be replaced.
The table shows the life of each part, and is measured when using A4 paper. When servicing a machine
always check the status of these parts using the control panel and ensure that parts are replaced at the
appropriate times otherwise a general degradation in print quality will occur.
