make sure the ribbon and correction tape are installed correctly between the metal fingers on the far side of the printwheel and the cardholder. make sure there is no forien objects in the P/W or anything touching the petals on the P/W. turn mach. off for 10 secounds then back on or just hold down the code key and hit the Q (reset) if it still doesn't work, it will need repair or replacement.

Try hitting [CODE] + [RESET] at the same time to reset the cartridge. Make sure the cassette is installed correctly.. the "ear" on the cassette should always be on the upper right.

Is there a correct side to the correction tape and will it dry out. This maybe why mine does not work. model # sx4000

The tape must be installed with the dull side toward the platen. Yes they do get old and don't work.

If you aren't in KBII or a language mode or P.S. pitch the printwheel homing pawl is probably broken. You need a tech.

Problem with the line spacing on my brother sx-4000 typewriter. The spacing wheel is not moving the paper down to the next line. I've moved the lever on the right side back and forth to see if it...

If all the settings are right and it feeds with the platen knob the plastic gear on the index mitor is probably broken the part is about 25.00 plus installation.

My typewriter keeps returning to the same line.

If it will space up with the platen knob the plastic gear on the feed motor is broken. The last time I replaced one the motor and gear was 35.00.

Brother SX 4000 stopped printing. Ribbon is

Remove and inspect the ribbon cartrige, wind the knob and make sure that the ribbon moves and reinstall. Check that the correction tape is installed properly. Check that the ribbon plate assembly is not in the correction position. Try CODE RESET (Q key)
