Section 7: Replacement Procedures
SATO M10e Service Manual PN 9001113A Page 7-17
5 Remove four screws (4) securing drive motor (5) to printer frame (1).
6 Disconnect motor wiring harness (A) from main circuit board wiring harness (B).
7 Replace defective motor (5) with replacement motor (5) and secure using four screws (4).
8 Orient printer frame (1) onto printer base (3) and secure using seven screws (2).
9 Route wiring harness (A) as was removed and connect to main circuit board harness (B).
10 Reconfigure the drive belt onto the motor spindle.
11 Replace the rear, left, right, front, and top housing covers.
RIBBON MOTOR REPLACEMENT
The stepper motor transmits motion to the ribbon rewind assembly. The energized motor
provides torque to the assembly via a toothed timing belt configured on pulley type gears. The
following procedure includes instruction on main circuit board removal to disconnect the motor
wiring harness. However, a very dexterous person will be able to disconnect the harness without
removing the board.
1 Switch off the printer and disconnect the power supply cord.
2 Remove the top, front, and left housing covers to expose the main circuit board.
3 Remove ribbon stock from the printer if applicable.
4 Remove two screws (1, Figure 7-14) securing cover (2) to ribbon frame (3). Lift away (1).
5 Remove one screw (4) securing cable bracket (5) to the printer frame. Lift away bracket (5).
6 Remove three screws (6) securing ribbon motor (7) to ribbon frame (3).
7 Disconnect motor wiring harness (A) from the ribbon drive board connector (A).
8 Replace defective motor (7) with replacement motor (7) and secure using three screws (6).
NOTE: It is recommended that the route of the wiring harness be noted prior
to motor removal and that the motor connector on the main circuit board be
tagged to ensure it is located for replacement motor connection.
NOTE: Figure 10-1 of the Diagrams & Schematics section provides guidance
on housing cover installation.
NOTE: Figures 10-1 and 10-3 of the Diagrams & Schematics section
provides guidance on housing cover and ribbon removal.
NOTE: It is recommended that the route of the wiring harness be noted prior
to motor removal to prevent binding or chafing upon replacement. Also, the
motor connector on the main circuit board should be tagged to ensure it is
located for replacement motor connection.
