Per Binary_Zen in a similar topic:
As previously mentioned it could either be the printhead carriage or the rollers. To differentiate if it is the printhead carriage or the rollers, do around 5-10 blank page copies. This process will force the printer to feed paper and then release it since there is nothing to print. If it is making the same noise then it is the rollers. If it did not make the noise then it is the printhead carriage (during printing).
If you are still in warranty I would suggest to call tech support to have it troubleshot and a possible unit replacement. In other forum posts they have placed lubricants on the carriage rod where the printhead is riding on. For some people it worked and some not. Its not something I could recommend since that rod is pre-lubricated from the factory plus I dont how it will affect the printer's internal parts.
