The cartridge installation instructions play for 10 minutes upon switch on before printer can be used. Upon switching the machine on, the cartridge carriers move to the centre (as though ready for a cartridge change) and the cartridge installation pictures appear on the screen. After 10 minutes I hear the noise of the cartridge carriers moving back to the left and the correct copy screen appears so that the machine can be used. This same problem has developed on three different machines! It occurs even when using genuine Lexmark cartridges. I am sure there must be a work-around but I have not found it yet!
