To Put on Check Paper Roll
Unlock Lock No. 5, push down catch and remove hood. Remove plate in front of check paper
roll by lifting up and off. Turn knob “G” until the word “off” is in correct reading position.
Place the roll of paper on the stud so that end of paper unwinds from the back; pass end of
paper down through the guide into chute “B” (see cut in front) just behind the felt inking roll;
feed paper forward until it comes out in front under the printing wheels; turn thumb-nut “G” to
the word “On”; turn the handle and the paper will be fed forward and cut off.
To Supply a New Roll of Detail Paper
Remove the wooden core that remains of the former - roll of paper from stud “J” (see cut in
front), raise the stud so that roll of paper will pass over gear wheel and push roll on firmly as far
as it will go. Push the paper and stud down into position. The paper must unwind from the
bottom of the roll. Pass the paper around rubber roll “A” and up to spool “C” and clamp end of
paper in groove of spool “C” with steel staple. Turn spool until the paper is drawn taut.
To Ink the Felt inking Rolls and Pads
When the impression on the check or detail strip becomes dim, remove the hood over the
printing device. The two inking rolls are found in the rear of the printing device, the one
immediately below the back electro roll, the other within the swinging paper chute which
carries the check strip. These rolls should be inked with the purple ink provided for this
purpose, using only a small quantity, just enough to moisten the roll, turning the roll so that the
ink may be properly distributed. The upper roll may be inked without removing same from the
register, as the long spout collapsible tube has been provided for this purpose.
