Brother Correctronic 40 Not striking

Typing when the letters started getting lighter, then quit striking at all. Can't find manual or support of any kind on the Brother site either. Brother Correctronic 40 is the only identifying mark I can find except what I think is a serial number WH2169805

You’re right Brother authorized service centers are hard to come by and now that the one that I was working for went bankrupt I can’t buy parts any longer.

Let me see if I understand the problem. When you start typing it’s ok and as you continue typing it get’s lighter then it finally stops printing? If you let the machine sit like overnight it starts all over? If so what you need is a .20¢ rubber bumper used to lessen the hammer noise.

What happens is the rubber get’s sticky with the heat generated from use. I have tried to find a substitute (for the Brother part) and nothing I have found lasts very long. If you just remove the bumper the hammer makes a terrible racket (too noisy for more people), and I suspect if it were used without the bumper the hammer mechanism would rattle apart after a short time.

I know this can be repaired easily but not cheaply. The machine is old, it’s time to consider a replacement. Sorry!

Want to purchase Correctronic gx6750 Manual ASAP

The Brother USA site has the manual as a PDF: . The direct link to the English language version is: .The manual for the Correctronic GX-6750 is also available to registered users at HelpOwl. You must be logged in to access the PDF: .

I don't see any options to purchase the manual. However, if you save the PDF, you can probably get it printed and bound at any print shop (UPS Store, FedEx Kinkos, etc).

I hope this helps.

When typing, the letters are not showing up well unless it is on double strike. have take printwheel out and changed ribbon but still not striking paper well.

The problem may be the ribbon or the media you are typing on. try typing on a mulit part form, if the copies are good then its the ribbon (OLD) or the paper (GLOSSY).

Brother typewriter correctronic gx-6750...prints gibberish.

Make certain the printwheel is latched fully into position. Observe the hammer movement while typing slowly NnNnNn. If the hammer does not come to rest at the same position every time the hammer cams are at fault. Make sure there is nothing interfering with the printwheel movement (like the correction tape or ribbon)

Brother GX-6750 correctronic

Check the print wheel to see if any spokes are bent or missing, be sure that you have the proper correction tape (tack free) and that you are not in proportional space or have an international print wheel.

Gently push the hammer up to the print wheel, does the notch in the hammer line up with the dimple on the back of the printwheel characters? You will have to look real close.

Typewriter won't type letters

HI.. the hammer solenoid may be should make a typing sound when you hit a key.( the printhammer moved and strikes the printwheel) or when you changed ribbons you might have unlatched the printwheel..there is a lever you press to relatch it until it "clicks"
If not that then make sure the ribbon is seated correctly, that it is between the printwheel and the black roller.Also visually inspect the ribbon so it is not caught in the printwheel.

Typing different letters than what i am striking

Your are on the wrong keyboard setting. Look around the typewriter,usually on the left side of the keyboard, and you will see a setting 1,2 or 3. Keyboard one is the one you want.
