How to Install Monroe Paper Rolls into a Monroe Printing Calculator

Step 1 Ribbon

Step 2 Ribbon

Step 3 Ribbon


Step 1

Turn OFF the calculator. Slide the printer cover off of the device. Put pressure on the cover at the top of the device, pushing off the cover.

Take note of the arms holding the paper roll in place. You’ll need to remove the paper roll core from the previous roll that you are replacing for a new paper roll.

Step 2

Install the new paper roll.*

Make sure that the paper sits so the paper is feeding up towards the sky and not down toward the ground. This will help keep the paper curling toward the back of the machine when you print.

Step 3

Now it is time to feed the printer paper into the printer. Look for a slot along the top-rear of the printer. Then, feed the paper between the slot in the printer.

Turn ON the calculator. Press the “FEED” button on the printer so the paper continues to be fed through the device properly.


Depending on the model calculator you may need to have the calculator lid installed before feeding the paper through the printer.

For the Monroe 6120X, 2020PlusX, and 122PDX lids must be installed before feeding the paper.

For the Monroe 8130X, 8145X, and UltimateX the lid does not need to be installed until afterwards.
