Grinding and locking typewriter

It sounds like there may be an issue with the belt or the motor in your Smith Corona super-correct electric typewriter. The ticking and grinding noise could indicate that the belt is slipping or that there is an issue with the motor. It's possible that the belt may have come loose or slipped out of place during use, causing the ticking noise and the typing issues you're experiencing.
To troubleshoot the issue, you could try removing the casing of the typewriter and inspecting the belt to see if it's in place and properly tensioned. You could also try cleaning the mechanisms inside the typewriter to see if that helps. If you're not comfortable doing this yourself, you may want to take the typewriter to a professional for repair.
In any case, it's important to be careful when working with electrical equipment. Always make sure the typewriter is unplugged and the power cord is disconnected before attempting any repairs or maintenance.

THIS SOUNDS TO ME LIKE YOU HAVE BEARINGS THAT ARE BAD. WHEN IT ACTS LIKES BRAKES ARE APPLY ON THERE OWN AND GRINDING,THAT IS THE BEARING LOCKING UP.HAVE CHECKED ASAP

the grinding noise is from the steering pump going into overload and the pressure relief valve is working. If you have recently worked on the pump or steering check that the hydraulic lines have correctly installed It appears that when turning right the steering is trying to turn left.

Check the cv joints as they make that sort of noise when they are worn out.

A "CLICKING" NOISE WHEN TURNING USUALLY INDICATES A BAD CV JOINT. LOOK AT SIDE MAKING NOISE AT INNER AND OUTER CV RUBBER BOOTS...IF CRACKED OR TORN....PROBABLY NEED NEW CV JOINT

That sound is going to be your door lock motors wearing out. I would suggest getting them replaced pretty quickly as they will soon stop locking altogether. It's not cheap, but it isn't horribly expensive either.

Try some WD40 on the silver shafts that the carrier slides on they do get very gummy.

replace the pass side door lock actuator

The print head lock is probably not retracting. Look for the white plastic block that pokes through from the paper feed side just in front of the head. Push it in with your finger and move the head to the middle by hand. Now turn the machine on. Then turn it off using the correct method. Then turn it on once more. If it starts grinding again, you screwed the feed mechanism when tugged out the jammed paper (probably pulled it backward through the feed instead of making it go forward and out the correct exit). If this is the case, you may as well bin it. If it in warranty, you can try to get a claim for repair.

make it sure the cover of typewriter was lock ,self lock no movement of cover means good operation of typewriter.
