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

• When an ink cartridge is installed into the printer for the first time it will take approximately 2 minutes to charge the ink system and initialize the printer. While the ink is charging the power light will flash. Never turn off the printer while the power light is flashing (unless the power light is flashing AND the printer has not moved or made noise for over 5 minutes). This initialization is a normal and necessary process.
