I've seen videos online which show this typewriter storing a number of letters on the LCD screen before typing them out....

You need to clear the saved margin settings from the on board memory chip before resetting them to your desired setting. To clear the margin and tab location settings: 1. Press RETURN (The carriage must be located at the currently set left margin.) 2. Press both the CODE key and the TAB CLEAR key simultaneously. This will clear both the margin and tab settings from memory. If successful, the carriage will move to the far left. To reset the desired margins: 1. Press the SPACE BAR until the carriage is located at the desired left margin. 2. Press the LEFT MGN key. This will save the left margin setting 3. Press the SPACE BAR until the carriage is located at the desired right margin 4. Press the RIGHT MGN key. This will save the right margin setting 5. Hit the RETURN key. If successful, the carriage will start a new line at the new left margin. New tab locations must now be set as well. To do this you must manually set each desired tab location on a given line using the SPACE BAR, and then pressing TAB SET.

Apply a few drops of WD-40 or a silicone-based lubricant to the roll and let it sit to re-oil the fabric. Place the drops through where the ribbon exits the cartridge. Be very careful not to overuse the lubricant as it can lead to an oily mess and an unusable ink cartridge.

If you look to the left of the keyboard, you will see two tan colored switches. Currently your typewriter has the right switch set to "NORMAL". This setting allows the typewriter to be used in the manner you described, to allow for a user's personal preference. If you set the tan switch to "DISP" then the typewriter will store a number of characters on the LCD for you to review before pressing the return key. The number of characters stored varies based on the set paper margins.
