- Scanner models do NOT have an ink button and you should use your setup button and the OK button and the same procedure you would use to change factory original inkjet ink cartridges to control the printer.
Other Epson models DO HAVE an ink button on the printer controls and you should use this button to control the printer during resettings.
The Stylus Photo 1400 RATF chip has two switches OR a single switch marked OFF/ON. in the case of the dual switch chip running position is BOTH switches moved to inboard position (this is both switches towards the middle/ left switch rightward position and right switch leftward position). The reset position is both switches outboard (this is both switches towards the outside/ left switch left and right switch right).
All movements of the switches should be made ONLY when you are in perfect alignement with the cartridge change area. those people that have unmodified printers this is easy as the ink bay cover can only be opened and closed when in alignment. Those with removed cart bay covers, ciss owners and otherwise, you must remember that movements of the switches in other positions will only error the process and result in no net gain. The switch movements send the code and the installation procedures to the printer and must be made in the correct sequences
It is important to remember that the RATF chip is not a reset "when you want to chip", it requires an "out of ink condition" to be exhibited prior to performing the chip reset. So wait for a red "x" (as in the video) before performing the reset. Also if you have a cartridge based refill system, you will want to refill the cartridges during the resetting procedure. You will want to refill all positions as you will be resetting all positions back to full at the same time.
