The printer is making some unexpected noises
You might hear some unexpected noises made by the printer. These are the servicing
sounds when the printer performs automatic servicing functions to maintain the health
of the printheads.
NOTE: To prevent any potential damage to your printer:
Do not turn off the printer while the printer is performing any servicing. If you are
turning off the printer, wait for the printer to come to a complete stop before turning
off using the (Power) button. See Turn the printer off.
Make sure all ink cartridges are installed. If any of the ink cartridge is missing, the
printer will perform extra servicing to protect the printheads.
