try to reset yellow+107 and tell me what happened

CS320 polygon motor (laser), you will need to replace it, it is not expensive!
CS672 control communication on start up, to many options, from circuit board to bad connection, you will need a tech for this.

If the model ia a MPC 2800 it a controller board issue maybe the operation panel. -carl

Measurement the countinously of the heater lamp,check the thermistor and thermofuses nad reset the error code.

sc 121 is related to optics section of your machine.check the lamp is glowing .if so check the connection from optics to main board.
