A drop assembly for a paper product dispenser is provided that transitions an upper carriage for a second roll of paper product into a primary or first position after depletion of a first or primary roll of paper product without user intervention. The drop assembly transitions the upper carriage into approximately the same position previously occupied by the lower carriage, allowing a small aperture in a front face of a dispenser to be used. Additionally, the drop assembly can include a reset connection to transition the drop assembly back to the firsts position upon opening of a dispenser front face.
