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

• Yes. It takes about 2 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 1½ 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.
