When performing maintenance on an impact printer after experiencing poor quality prints, an error-free self-test printout, and hearing unusual noises during operation, which of the following is the BEST action to take?
Replace the print head, since it is responsible for the physical impact required to make prints.
Replace the printer paper, since defective paper could affect print quality.
Replace the ink ribbon, as it is the component that transfers ink onto paper.
Refill the ink ribbon, believing the ink has possibly dried up.
The correct action to take is to replace the print head. The evidence pointing to this action includes poor quality prints despite an error-free self-test printout and unusual noises during operation. These symptoms can be caused by physical wear or damage to the print head, as the print head is the component that impacts the ribbon to transfer ink onto paper. The other options are less likely to cause unusual sounds during printing and are not directly related to the print quality when a self-test printout error is absent.
