 A. If it is not possible to print the ACARS (or ATSU) 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 (with MU-ACARS installed):
 - replace the MU-ACARS (1RB) (Ref. AMM TASK 23-24-34-000-001) and (Ref. AMM TASK 23-24-34-400-001).
 (a) If the fault continues:
 - do a check of the wiring from ACARS MU (1RB) pins AB/15E, 15F to printer (4TW) pins A/T, U (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 MCDU2 (3CA2) pins A/27, 28 to ACARS MU (1RB) pins AB/14C, 14D (Ref. ASM 22-86/04).
 a If there is no continuity:
_ - repair the wiring.

 b If there is continuity:
_

 - replace the MCDU-2 (3CA2) (Ref. AMM TASK 22-82-12-000-001) and (Ref. AMM TASK 22-82-12-400-002).
 (2) If the fault continues (with ATSU installed):
 - replace the ATSU (1TX1) (Ref. AMM TASK 46-21-34-000-001) and (Ref. AMM TASK 46-21-34-400-001).
 (a) If the fault continues:
 - do a check of the wiring from ATSU (1TX1) pins AA/1E, 1F to printer (4TW) pins A/T, U (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 MCDU2 (3CA2) pins A/27, 28 to ATSU (1TX1) pins AB/7E, 7F (Ref. ASM 22-86/04).
 a If there is no continuity:
_

 - repair the wiring.
 b If there is continuity:

_

 - replace the MCDU-2 (3CA2) (Ref. AMM TASK 22-82-12-000-001) and (Ref. AMM TASK 22-82-12-400-002).
