The lower roll should be removed by swinging the paper chute back and lifting the roll out of
the slots in the supporting lugs after which the ink may be applied.
To Ink the Felt Pad
Remove the lower pad by pulling same to the right or away from the register using for this
purpose the small tweezers found in the supply box. Apply a small quantity of the BLACK INK
and replace pad in pad holder, being very careful to see that the metal plate which supports the
pad fits into the grooves in the holder.
To remove the upper pad, turn the operating handle one complete turn, which carries the pad
holder to a position where the pad can be removed, inked and replaced as described above.
Important
Use the purple ink on the ink rolls ONLY and not on the pads. Do not use any ink except that
which is sent with the register or purchased from The National Cash Register Co. Other inks dry
or gum and prove very unsatisfactory.
To Reset the Total Counter to Zero
This counter must be reset to zero before the clerks' counters are reset.
See that one of the initial indicators is in view, as the register cannot be reset unless an
indicator shows. Unlock Lock No. 1 (see cut in front). See that the operating handle is at the
home position. Put resetting key in hole above handle on right side of register and turn it from
you until it comes to a dead stop and all the adding wheels show zero. Turn the resetting key
slightly backward and remove it. If any of the figures should remain in the openings, reset the
counter, and be careful to see that the wheels are all at zero before locking Lock No. 1. Never
start the handle until the reset- key has been removed.
