TIMING BELT REPLACEMENT
The M84pro Printer utilizes four timing belts coupled with dual action toothed pulleys to provide drive distribution throughout the assembly. Two belts are configured to transfer torque from the motor to the label feed roller. A third belt transfers torque from the feed roller to the platen roller. And the fourth transfers torque from the platen roller to the ribbon rewind spindle. All four operating in conjunction provide the total drive configuration for the primary machine.
The optional cutter assembly has its own drive mechanism that operates when directed by the printer, but independently of the printer drive assembly. The cutter drive assembly also comprises drive belts and pulleys. Those will not be addressed in this procedure.
