Press and hold down "Store" while you type the number you would like to store the information in ( 1 through 99).
The "Store" light will blink and then the printwheel will spin.
When the "Store" light comes on solid you may start typing.

To end the store operation simply press and release the Store key. The Store light will turn off and the printwheel will spin again.

To print the saved job press "Play" and the number you used.

(Note: there are batteries inside the ribbon area of the typewriter that should be replaced every year (AA batteries) If they are missing or dead, the stored jobs will dissappear when the typewriter is turned off.

A copy of the operator's guide can be found here:

First be sure the platen is fully seated and locked in the side frames, Then be surethe ribbon is on allthe way, then try it without the L/O tape.

Check if there's something between the ribbon and the platen(roller). I think there is.

Without having the operator manual what I recall on these types of type writers, they have a key next to the space bar called "Features Key."
Most keys are color labeled.
Select the bold feature, it's color origin,
1. Press and hold that features key
2. Touch the bold key, now you are in bold typing mode.
3. When you finish bold typing, press the features key and hold, then touch the bold to turn it off.

Try hitting [CODE] + [RESET] at the same time to reset the cartridge. Make sure the cassette is installed correctly.. the "ear" on the cassette should always be on the upper right.

Check the connectors from thr PC board to the keyboard, if they are OK tren try this hold the code key press and release the "L" key type 001 release thecode key. If this works you need a keyboard to repair it'
