Brother GX 36750 - I replaced the ribbon, re-installed the daisy wheel, reset the pitch, pushed CODE RESET, but the letters I type are not matching what is printed on the paper. I press 't' and it types 'd'. Help?

Chances are that the print head is not locked forward. This happens when the daisy wheel or either of the ribbons are replaced. Just push it forward until it clicks

It sounds like you installed a printwheel wit a very small font probably 15 pitch put in one with larger print.

first try turn typewriter off, (button on left panel toward the back), then turn it back on, and while hold down the CODE button, press RESET key, the whole print head will move and reset

if that doesn't work, power off again, open the cover, release the lever to the Daisy Wheel, and inspect that Daisy Wheel - mine has a bent forward letter, and another letter was kinda stuck to the side of another letter... I gently fix both letters, put the Daisy Wheel back in, firmly lock it in place with the lever, close the cover... and voila, it works like a charm.

While you have it open you might want to dust (use the cleaning spray can duster)... You wouldn't believe what I found in my typewriter... Good luck!

If that doesn't work, I would replace the Daisy Wheel.

Your daisy wheel letters are bended not straight.

Switchoff just remove your daisy wheel & remove the daisy wheel from its cover & see all the letters should be straight.If any of them is bended jst make them straight by your fingers dont press too hard & then fix the daisy wheel back & switch on typewriter.

look for bent or broken spokes on daisy wheel .turning unit off for 20 seconds and back on should reset the daisy wheel home position. probably the daisy wheel.

I called a local dealer for instructions. Apparently I accidentally released the daisy wheel when installing the new correction ribbon. Thank you.

Press the Code button and the Q/Reset button at the same time and the wheel will spin and go back to the correct place.

Install wheel, turn machine on and off this resets the printer and home timing. If it still does not correctly, adjustments needed..

The ML-300 needs to be reset each time the Daisy Wheel is removed or replaced or if the Keyboard Switch changes position. According to Brother, if this is not done the typewriter will print incorrect characters. Try these steps: 1) Open the Top Cover. There is a lever directly behind the Daisy Wheel. Pull the lever back towards you. Remove the Daisy Wheel by pulling it up and out. 2) Verify that it is the Standard Daisy Wheel that came with your machine and not a Symbol or International Daisey Wheel. Write down the Pitch (10, 12, or dual pitch 1012) printed on the wheel. 3) Reinstall the Daisy Wheel (the plastic top ear goes to your right.) Push the lever (step 1) forward. 4) Press the ALT key plus the PITCH key and the number 1 key simultaneously. Verify the Pitch setting is the same as is printed on the Daisy Wheel. 5) Press the CODE key plus the RESET key and the letter Q key simultaneously. This will reset the typewriter mechanism and align (or time, in technical terms) the carriage mechanism. Check if the typewriter prints correctly now. If still incorrect, perform these additional steps. 6) Verify the three position Keyboard Switch (inside the top cover, on the right side, at the bottom) is in the I=Standard position. The other positions are: II=International and III=Symbol. 7) If the Keyboard Switch is in the correct position, slide it to position III and then back to I. (This will clean the switch contacts in case they are dirty and not making good electrical contact. 8) Press the CODE key plus the RESET key and the letter Q key combination again to reset the typewriter mechanism. Check if the typewriter prints correctly now. If still incorrect, the only other things I can think of is that: 1) an incorrect Daisy Wheel is installed that does not work in the ML-300. Brother sell a "B type" Daisy Wheel with two plastic ridges/raised slots below the center of the Daisy Wheel (viewed with the raised top tab on your left.) The B type are incompatible with your machine. 2) the typewriter has failed and needs repair.

Your T/W neads a new keyboard membrane, you cannot clean this type membrane so you will have to replace it.
