sounds when the printer performs automatic servicing functions to maintain the health

NOTE: To prevent any potential damage to your printer:

turning off the printer, wait for the printer to come to a complete stop before turning
it off using the (Power) button. For more information, see Turn off the printer.
Make sure all ink cartridges are installed. If any of the ink cartridges are missing,
the printer will perform extra servicing to protect the printheads.
