This is the follow up to a recently obtained electronic typewriter that was purchased in January 2025, the initial post can be found here: Samsung SQ3000 electronic typewriter.

The following post will deal with the assessment on its arrival and what I am going to try to do, to get it back working again, as close as possible to its original state.

I’ve downloaded an instruction I manual, I’ve had to download one for a Smith Corona Wordsmith 200, it is in theory the exact same unit, just under a different manufacturers branding.

Assessment

It’s arrived and apart from a little age yellowing it looks ok. There is a PAT testing sticker that says it was last electrically tested back in 1998 and is due a retest in 1999. This corresponds with my date estimate of mid 90s.

I will retest and renew the safety checks when I’m finished working on it. I have noticed that the paper bail/release rail is broken on the left hand side so I will have to add that to the repairs, this shouldn’t be a major concern.

Before I took the roller out to get to the paper bail I did start the machine up. Everything went as expected and when I tried to type I was getting some weird reactions to the keys I was pushing. All kinds of characters were appearing.

I checked the daisy wheel and there was a click. It wasn’t sitting right. I reset the machine using the two reset buttons and the machine then went through its reset programme, pretty much the same effect as turning it off and on again. (Not much changes in the way of tech there then)

Well that’s worked fine, I have tried every combination on the keyboard including the erase function and this is now fully working. It really was quite simple. My next job is to try and fix this paper bail.

There is quite a bit of dust and dirt inside that needs removing. And whilst I’m at it I will lightly re grease the areas that need it. Let’s be honest it’s not been done in the last 30yrs so now is as good a time as any. Inside will get a light hoovering and a bit of a tart up, I’m not going to go mad. I will clean the outside and all knobs and buttons and try to get rid of some of the yellowing, but to be honest as long as it’s clean I’m not too worried about age marks.

The keyboard has lost a few of its letters. I will remove what is left of some of them and use some keyboard decals to replace the missing ones. This will be one of the last jobs I do.

Well that’s the assessment done and apart from a few small issues and requiring some basic maintenance I don’t think we have an immense amount of work to carry out. We know it now works. Let’s hope I don’t cause any further carnage whilst working on it.

Let’s get to work.

Repair

Right it’s straight onto the paper bail to try and fix the snapped end. Firstly I’m just going to use some superglue to get it in place. When this is dry I’m going to create two “Doublers”, place one either side of the damaged part and glue these in place to create a stronger repair and to add some stability to this area.

I’ve got some black semi rigid plastic. I’ve created a small template from a tracing that I did of the good right hand side of the bail.

I now have two doublers cut from the plastic that I will use as explained above.

It doesn’t matter that they are not perfectly shaped, however they both fit perfectly well into the profile of the bail arm, and this portion of the arm is hidden in the typewriter housing anyway, so the part will not be visible, but it will now be strong.

The Doublers have been put in place using a quick set epoxy resin, I will leave this to dry for a good few hours before I tidy it up, with a light clean, and then I will try to get it back in place.

Now that’s done i’ve gone inside and there were a nice couple of spider webs around the transformer that are now history. I’ve secured the cable in the rear of the unit that never had any tension restraint, so that there will be no issues, should anyone now give a good yank on the cable lead. This is a safety addition I have made that was never on the original unit.

I have also tightened all screws and checked the wiring and this all seems ok. Plug and fuse have been checked and all is looking good. I’ll carry out a PAT test once I’ve finished the clean up.

I’ve cleaned the main roller with alcohol, and removed all the old grease and dirt from the platten adjuster switch and the roller advance knob. I have removed the platten plate as well as the six mini rollers that are here. I’ve cleaned them all and re assembled/installed them.

I have cleaned the daisy wheel as well as in and around the printing head unit.

Inside the unit I have given a good hoover as well as a light clean and again removed more old grease. I have given the exterior plastic a preliminary polish, this has removed some of the yellowing and made it look “cleaner” I am not going to worry too much about the yellowing as it isn’t that bad, and I don’t really want to venture into carrying out a “Retrobrite” on this unit. It would take too long and there would be no benefit for this project.

I’ve now added very small amounts of a watch lubricant to those areas that i have previously cleaned and removed the old grease from.

The unit has been reassembled and I’m pleased to say it is still working fine. It’s running smoothly and all aspects of the unit seem to be working just fine. To be honest it seems to be printing clearer to me.

I don’t know how long the print cartridge has been installed but I suspect it may have been a few years back. It’s almost finished, and I do have a replacement on order. I’m sure a fresh cartridge will make the print stand out even more.

Next I’m going to have a go at replacing some, or even all of the keyboard letters. It all depends how it looks when I start replacing them. I’m going to gently rub off the lettering that is left and clean the keys using a 95% pure Isopropyl alcohol solution (IPA).

These are the replacement key decals I will be attempting to use.

I’ve replaced the damaged key decals. The ones I’ve used are a lot brighter than the original ones and really accentuate the yellowing. I’m not troubled by this as it keeps its “Old” look. I would have to scrape and wipe for hours to remove all the other keys and to be honest it would look just like someone had gone abroad to have a bright white set of dodgy veneers installed, it would look quite out of place, and in your face. Just like a Cheshire Cat smile.

It serves a purpose and just allows the unit to be usable again.

The final product:

Fortunately a lot of the equipment and parts I have used, I was already in possession of, so there are no additional costs for this project. Below you can view the total costings for this project as they currently stand:

• Purchase inc postage £13.14
• Cable restraint £0.25
• Keyboard decals £1.25
• Total cost of project £14.64

Again I have managed to save a fantastic 90s retro item from landfill for very little cost, and that is a fantastic result. It has years of use left in it, as long as the consumables remain available, and of that I am confident that they will be available, for at least the next few years. The unit is clean, I’ve just carried out an electrical PAT test and it is electrically sound.

Believe it or not I’m going to go back in time and will write some traditional typewritten letters to friends and family. I’m looking forward to doing that and it will certainly surprise them, it will be totally unexpected.

When all that is done, i will donate this unit to our local LOROS Hospice shop so they can sell it on and raise much needed funds. They deserve it. Edit: This was done in March 2025 at their shop in Hamilton Leicester. I hope it gets them a good price.

Thanks for passing by.
