I installed new ink cartridges and my product seems to be doing a long cleaning cycle. Is this normal?

• Yes. It takes about 5 minutes for the printer to charge the ink delivery system when you install the first set of ink cartridges. When you replace the ink cartridges the printer takes about 2.5 minutes to charge the ink.
  
  Note:
  Never turn off the printer while it is charging the ink delivery system (unless the printer hasn't moved or made noise for more than 5 minutes). This initialization is a normal and necessary process. If the printer initialization does not stop after 5 minutes, turn the printer off and contact Epson technical support for assistance.
