Reinserting the controller board
Note:
If you are installing additional memory, install it on the controller board before you reinsert the board. See your printer manual for instructions.
1.Hold the controller board level and fit its right edge into the right groove inside the board slot. Then gently fit its left edge into the left groove.
2.Slide the controller board into the printer until it locks in place. If the controller board does not fit smoothly into the printer, do not force it. Remove it and make sure the edges fit properly into the grooves inside the slot.
3.Secure the board with the four silver screws you removed earlier.
