IBM 4232-302 -- Main Sensor Cable Removal

This procedure deals with the cable that connects to the Logic PCA at J3 (upper right corner of the PCA). It's the cable for the AFTA sensor, the EOF sensor, the Door Closed sensor and the carriage motor.)

Proceed as follows:

1) Cover off.

2) Forms Device
- Remove it.

3) Left Side Air Deflector
- It slips off the frame rearward and upward. There's a rightward-projecting pin on it that the rear shield interferes with a bit.

4) Right Side Air Deflector
- One M4x10mm slotted hex washerhead screw (6mm A/F hex).
- Free the control panel cable from its clip at the right side.
- Lift the deflector off the frame while flexing the rear shield A/R.

5) Rear Shield
- At left side, two M4.5x10mm hex washerhead threading screws(7mm A/F hex).
- At right side, one M5x8mm hex washerhead screw (8mm A/F hex). Just back it out till it's clear of the rear shield.
- Lift the rear shield out.

6) Cable
- CAUTION: The cable connector at an elderly EOF sensor is likely to be fragile and stubborn. Disconnect it with great care.
- Disconnect at carriage motor, DC sensor, AFTA sensor and EOF sensor
- The cable is easily extracted from the two leftward cable restraints. The cable restraint by Logic PCA J7 has to be dislodged from underneath.
- Free the cable from the chassis entirely.
