Something else you might check, I was having same problem. Make sure the Daisy Wheel Lock Lever (check the description that comes in the guide) is locked in place, i.e., push it forward to lock. It is the black thing that sticks up on the right inside the correction tape. I did this and words started appearing. Hope it helps.

Check to be sure that the correction tape is in properly and tight. Then make sure that the ribbon (and correction tape) are between the two metal "fingers" and the cardholder (which is the metal thing that holds the paper close to the platen right in front of the ribbon) Is the ribbon moving? You should be able to hold the ribbon up and see each letter on the ribbon. Also make sure the printhammer is locked forward. You should not be able to just reach in and take the printwheel out without the ribbon in place. The only other thing I can think of, is the ribbon got twisted some how. The dull side should be towards the paper.

The return key does not work and even with a new ribbon the text does not show up on the paper.

Imagine your fingers are spread out and the have letters on them, a small electromagnetic hamer smacks the backside of your finger pushing it into ribbon and paper this makes a letter. What is occurring is the hamer is fireing between your fingers and hit the space between them, no letter is formed. Check your daisy whell or change it, the return key most likely has a cracked solder joint where it is conncected to the circuit board, if you can get the cass of I could probably talk you though the procedure but that's pushing it if you've never used a soldering iron, good luck,Bret

  1. Is the daisy wheel locked in the forward position?
    1. Pull the black lever back, away from the platen.
    2. Lift out the daisy wheel and inspect it for damage; replace the daisy wheel if it is damaged.
    3. Re-insert the daisy wheel and push the black lever towards the platen until it locks in place.
  2. Is the ribbon moving?
    1. Lift the ribbon cartridge out of the typewriter
    2. Inspect the ribbon for damage
    3. If the ribbon is silver, it is exhausted and must be replaced
    4. If the hammer has been striking in one place, there will be a clear area near the center of the ribbon.
    5. Turn the colored knob on the left side of the ribbon cartridge counter-clockwise to advance the ribbon a small amount. Replace the ribbon if it will not advance.
    6. Re-insert the ribbon
  3. Turn on the typewriter, insert a piece of paper into the typewriter and type a few letters
    1. Did the hammer move forward?
    2. If the hammer moved, did the ribbon advance with each keystroke?
If the hammer did not move or the ribbon did not advance, the typewriter will require service. If the typewriter still does not make an impression on the paper, your typewriter will require service.

My Remington Noiseless 1939 typewriter has ghosting on the letter keys. I have put on a new ribbon but this just shows up the ghosting of each letter more than ever. I notice when typing the carriage

Could also be that your paper is too fibrous of finish. I found this page because my typewriter was ghosting, too. I adjusted some of the settings and there was not a trace of ghosting. I put the settings back and still no trace of ghosting. Then I realized that I tested for ghosting on paper that has a much smoother finish. I was ghosting on cheap paper we use here at work. So, I don't blame the typewriter. I blame the cheap paper. My typewriter just likes good paper.

could be a defective ribbon, try new one if it looks like the letters are almost typing on top of each other on the ribbon. it could be a problem with the ribbon drive of the printhammer. if a new ribbon doesn't help, get professional help.

When typing the keys sedem to hit the paper forcefully but there is no letter produced. Just an indedntation in paper.

Is the ribbon lifting? There may be a lever for the ribbon setting, usually with color settings. Make sure it's on black.

Hi, I have a 1967 Smith Corona Corsair portable typewriter with case. All works fine except that the ribbon does not lift when keys hit the paper. So the keys end up hitting the paper directly (not through...

Is the ribbon selector lever located on the right side of the keyboard switched to either red or black? If it's on white, the ribbon doesn't come up.

Letters aren't striking ribbon

Get some WD40 and spray it on thw segment (the place where the type bars are swung) then everywhere the key mechinism pivots.

You may need a ribbon motor or motor board, however on the older wheelwriters sometimes the gear mesh gets sloppy and gears jam tooth for tooth. Try moving the ribbon lift gear/cam on rt. side of the carrier by hand with the machine off if it won't move that's the trouble. Wiggle it back and forth and it may free up.
