4.2 Loading Tissue Rolls
- Open Dispenser: Use the key to unlock and open the front cover of the dispenser.
- Insert Primary Roll: Place a new 9-inch jumbo bath tissue (JBT) roll onto the primary spindle (usually the right side). Ensure the tissue feeds from the bottom of the roll.
- Insert Reserve Roll: Place a second 9-inch JBT roll onto the reserve spindle (usually the left side).
- Thread Tissue: Pull a small amount of tissue from the primary roll and thread it through the dispensing slot at the bottom.

5. Operating Instructions
The San Jamar R4070BKSS dispenser features an Infinity System for continuous tissue availability.
- Dispensing: Users pull tissue from the bottom slot. The dispenser is designed for easy, single-sheet dispensing.
- Automatic Transfer: When the primary roll is fully depleted, the Infinity System automatically releases the reserve roll into the dispensing position, ensuring uninterrupted service. This mechanism prevents access to the spare roll until the first is empty, eliminating stub roll waste.
- Refilling: When one roll is depleted and the other is in use, open the dispenser and replace the empty spindle with a new 9-inch JBT roll.
6. Maintenance
Regular cleaning and maintenance will ensure optimal performance and hygiene.
- Cleaning: Wipe the exterior surfaces of the dispenser with a soft cloth dampened with a mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive pads that could scratch the finish.
- Interior Cleaning: Periodically open the dispenser and wipe down the interior to remove any dust or paper residue.
- Inspection: Regularly check the mounting screws for tightness and ensure the dispenser is securely attached to the wall. Inspect the internal mechanisms for any signs of wear or damage.
