Abstract:
1. A system for transporting media in a printer, the system comprising: a housing of the printer; at least one roller rotatably mounted to the housing for transporting media through the printer; a motor mounted to the housing; a drive belt looped about a drive shaft of the motor and the roller so as to impart rotational driving force of the motor to the roller; a tensioning member pivotally mounted to the housing for contacting and thereby tensioning the drive belt about the motor drive shaft and roller, the pivoted position of the tensioning member relative to the housing determining the amount of tension imparted on the drive belt; a brace member mounted to the housing about a slotted arm of the tensioning member; a locking screw fixed to the housing through the brace member and slotted arm to lock the pivoted position of the tensioning member, the brace member being fixedly mounted to the housing so that rotation of the locking screw is not imparted to the slotted arm during fixing of the locking screw to the housing; and a spring for biasing a bushing of the tensioning member against the drive belt thereby imparting the tension on the drive belt.
