Sometimes my typewriter advances too much between letters.

There is an escapement type mechanism in the back of the typewriter, chances are, the escapement mechanism is out of movement or misaligned. Check the spacebar if something is caught underneath or over one of the linkages.

Hammer sticking and typing incorrect letters (and or skipping letters): 1) make sure daisy wheel installed correctly. 2) hold down CODE key & Q (RESET) to reset wheel...if still not corrected 3) WD40 the hammer at the base & joints where moving parts are, keep typing until oil seeps in (this last one fixed it for me)

Typing light and inconsistant-top part of letter okay but bottom too light or not there: to left of hammer (at base) are 2 screws, I losened them and adjusted hammer to different forward and backward spots..finally found the ideal location where full letter printed and had the correct force it needed to print correctly.

Try it without the lift off tape they nsometimes jam the printwheel.
There may be a broken wire in the harness about 1" from the carrier.

Spray a little nWD40 on the silver shaft tha the carrier slides on.

If the problem is always with the 1 then the spoke on the printwheel is likely bent.

Hi

Many brother type writers have two cam assemblies under ribbon holder. One operates the print hammer and the other operates the correction ribbon lift. sometimes they gets stuck or lock themselves up. turning on and off a few times will take care of it, but sometimes it needs to be worked on by a tech. If you look when you type a character, most likely the print hammer is not firing or it is striking the correction ribbon instead of the black ribbon.

Let us know if you want to know something more else please accept the suggestion.
Thanks for contacting Fixya.com

You might have a "proportional space" printwheel but the pitch selector is on 10, 12, or 15 instead of PS. OR it is on PS but you have a normal print wheel. Try selecting different pitches. Another thing that causes that problem is sometimes the ribbon or correction tape gets caught in the printwheel.

REMOVE THE PRINTWHEEL, LOOK FOR BENT OR BROKEN SPOKES, ALSO BE SURE THAT THE CORRECTION TAPE IS THE DRY TYPE, THE STICK ONES WILL GIVE YOU FITS.

check you type wheel ,and clean your optical reader ,optical reder read`s your typewheel and because of some dirt sometimes printer moves a type wheel one step forward and you get a II.

Take a look at the ribbon, making sure it is moving eack key stroke you should be able to read you typing thru the ribbon.
