and
CN7
on the printer control board BA-T500 (A).
3. Retain the control board to the printer bracket from the

the other ends of the 21-pin and 15-pin flat cables come
out from the rectangle opening at the right side of the
bracket.
4. Fix the paper tray (F) to the metal bracket (E) with two
M3*2 nuts.
