 B. Test
 On the MCDU1:

 - get the EVMU page on the MCDU MENU and then push the line key adjacent to the PRINT indication.
 4. Fault Isolation
_______________
 A. If it is not possible to print the EVMU data on the printer (4TW):
 - replace the PRINTER (4TW) (Ref. AMM TASK 31-35-22-000-001) and (Ref. AMM TASK 31-35-22-400-001).
 (1) If the fault continues:
 - replace the EVMU (2EV) (Ref. AMM TASK 77-32-34-000-040) and (Ref. AMM TASK 77-32-34-400-040).
 (a) If the fault continues:
 - do a check of the wiring from EVMU (1EV) pins AA/13A, 13C to printer (4TW) pins A/j, X (Ref. ASM 31-35/01).
 1 If there is no continuity:
_ - repair the wiring.

 2 If there is continuity:
_

 - do a check of the wiring from MCDU1 (3CA1) pins A/27, 28 to CFDIU (1TW) pins AB/3H, 3J (Ref. ASM 22-86/04).
 a If there is no continuity:
_ - repair the wiring.

 b If there is continuity:
_

 - replace the MCDU-1 (3CA1) (Ref. AMM TASK 22-82-12-000-001) and (Ref. AMM TASK 22-82-12-400-002).
 B. Do the action given in Para. 3.B.
