A repeat/error lever is on the left, and total/sub-total, non-add, and non-print keys are on the right. Numbers are set by pressing keys and entered by turning a handle on the right side of the machine. The printing mechanism (which displays totals of up to eight digits), black ribbon, and paper tape are at the back. Both spools of the ribbon are on the left side and it is threaded across the back in a C-shaped path. Two of the five rubber feet are decaying. This example of the machine has an extra paper tape.
