Indicates a problem with the carousel assembly. The carousel might not be turning or the sensor might bad or more likely just covered in toner and in need of a good cleaning.  The toner cartridge carousel is driven by the drive motor. It is a 6-phase (speed) stepping motor. If motion is not detected the error will appear. The motor receives its drive signals from the developing  PCB. The photo-sensor monitors the movement and the position of the toner cartridge  carousel. Different width tabs ( four tabs, one for each cartridge ) on the left end of the carousel that pass through the sensor to provide the positioning information. The black toner cartridge tab is the home position.  The carousel might start and then stop immediately. These sensors get very dirty with toner from the printing process and need to be cleaned periodically to avoid this error. The use of a toner vacuum is needed to clean them. Remove the top cover to gain access. If the sensor is installed backwards  a 54.2 error will occur.
