this indicates a the print head is not installed correctly or is faulty.

if the green and orange is alternating 5 times then it is caused by the sheet feeder.

Needs resetting at best.....perhaps it might shut down completely.....I had the same problem then my printer completely shut down!

Probably your waste ink counter. Should be cleaned or replaced before resetting but usually you can get away with resetting once.
1. Start with printer OFF
2. Hold down RESUME and then hold down POWER
3. Release RESUME
4. press RESUME twice, then release POWER
5. let green light blink until printhead has finished moving.
6. Select functions below with RESUME, execute with POWER

0 presses - green light - Test Print (exit service for i960)
1 press - orange light - EEPROM info print
2 presses - green light - EEPROM initialise
3 presses - orange light - reset waste ink counter.

This also applies to the i550, i560, i950, i960
