P 8000 Printer maintenance

The Menu choices on the P 8000 LCD do not correspond to the 9900 video showing how to perform preventive maintenance to the capping station, flushing box, etc.; i.e. Mecha Adjustment—> Enter: there is no Maintenance selection, same for the “Life” selection
How do I get to Flushing Box and Wiper to clean them, they are not visible? Can you provide specific steps/walk through instructions to follow on the P 8000 LCD?
