Question about Brother ML-300 Typewriter

1 Answer

Changing ribbon Hi, I have an ML-300. Unfortunately, the old office manager only left manuals in French and Spanish, neither of which I speak. I know this should be common sense, but when I try to put the cartridge in it sits too high. Also, I took the correction tape out to try that so I may need help getting that in as well. Please help! Thank you.

I have a customer who bought a Brother ML 300 typewriter a little over a year ago. When she is typing, and then hits return, the printwheel is not hitting the paper. I checked the printwheel to be sure...

Hi - there a many reasons why this happens. Try these first. Replace the ribbon. This might have become tight (faulty) and make this happen. Nasty fault? maybe the power supply has caused error and lacks power in the hammer to hit the back of the print wheel.

How do you change ribbon cartridge?

just pull up on the part of the ribbon cartridge closest to the printwheel, there is just a small clip to the right of center holding it in, and pull it out. when you install the new one make sure the ribbon advance knob on the ribbon is on the top left. you slide the rib. cart back into the ribbon plate (the place it sets on) untill it stops and the lugs on the bottom of the ribbon lock it into place and then push down on the front of the ribbon till it clicks into place. take a good look at it before you take it out so you can see shere it is supposed to go.

Can parts be changed out


Yes. The Brother ML 300 and the Brother ML 500 use the same products (Typewriter Ribbon, lift off tapes and Daisy Wheels).

Take care,

Beeping sound when powering unit on

Have you simply pushed the carriage back to the middle? If it is like the ML100 (it looks the same) you can just push it over ...with the pwoer off. Then put in you new ribbon. And this time, when you turn it on, it is the new ribbon that hits a switch on the underside of the keyboard, located to the upper left. If you do not have a ribbon installed, it will travel all the way to the left, and beep, beep, beep, beep. ,,,, The switch is hit with the ribbon housing.
