3 Loosen screw (2) to relieve tension on belt (1) by tension roller (3).
4 Withdraw belt (1) from platen roller pulley (4), feed roller pulley (5), motor spindle (6), and
tension roller (3).
5 Apply replacement belt (1) onto motor spindle (6), feed roller pulley (5), platen roller pulley
(4) and tension roller (3) oriented as was removed.

7 Reattach right housing cover, restore power, and test cycle.
RIBBON BELT REPLACEMENT
The M10e Printer utilizes two timing belts coupled with toothed pulleys to provide drive
distribution throughout the assembly. One belt is configured to transfer torque from a stepper
motor to the platen and feed rollers. A second belt operates independently from the first and
transfers torque from a second stepper motor to the ribbon rewind assembly.
1
Switch off the printer and disconnect the power supply cord.
2 Remove two screws (1, Figure 7-3) securing motor cover (2) to expose timing belt (3).
3 Remove two screws (4) securing bracket (5) to ribbon frame (6).
4 Withdraw bracket (5) along with collar (7) from ribbon frame (6).
5 Withdraw timing belt (3) from pulley (9) and manipulate from motor (10).
6 Apply replacement belt (3) onto spindle of motor (10) and pulley (9).
7 Apply bracket (5) with collar (7) to ribbon frame (6).
8 Secure bracket (5) to ribbon frame (6) using two screws (4).
NOTE: More specific instructions on belt tension adjustment may be found in
the Adjustment Procedures section of this manual.
NOTE: Leave the encoder wheel (8) and all components behind it, on the
ribbon shaft without disassembly.
NOTE: Since the belt will be discarded, it is recommended that it be cut to
facilitate removal.
NOTE: Loosening the three motor mounting screws will provide additional
space for belt installation onto motor spindle.
NOTE: When properly applied, the flange of the collar will rest against the
inner surface of the bracket while the sleeve portion is inserted into the slot.
