It’s about time I started to get back to repairing some cameras, I have a mountain of them to get through but they can wait a little longer. These little Fuji units are really popular with the younger generation, and in my view anything that gets youngsters interested in, and involved with photography is a good move. We have some youngsters in our clan, and I have this earmarked for one of them if I can get it working. We had some conversations during our family gathering over Easter, and the subject of photography, and this particular member of our family came out. Seeing this auction today, I acted and purchased as this is a perfect little starter unit for her. My total outlay for this unit was £11:45GBP and considering the current costs are around £30-£40GBP for a working example, this is not too bad an initial outlay.

Here’s some history on these cameras:

Instax is a brand of instant still cameras and instant films marketed by Fujifilm.

The first camera and accompanying film, the Instax Mini 10 and Instax Mini film, were released on November 10, 1998. The “Wide” film and first accompanying camera were released the following year. The Instax Square film and accompanying camera were released in 2017.

The formats of Instax film give an image size of 46 mm × 62 mm (1.8 in × 2.4 in) for the Mini, 99 mm× 62 mm (3.9 in × 2.4 in) for the Wide and 62 mm× 62 mm (2.4 in × 2.4 in) for the Square. The Instax colour film is available in Mini, Wide, and Square formats and the black and white Instax Monochrome is available in Mini and Wide formats.

For anyone that was around in the 70s, these cameras are an extension of and an advancement of the then Polaroid instant photography system. Nearly every household back then had access to Polaroid cameras. If you look back at any photo album or collection from that time, you will invariably find some Polaroid photos stored within that collection.

Here is a typically over enthusiastic review produced by a very pleasant chap when it came out about 8 years ago. Sums up in a few minutes just what it can do, and just how easy it is to use.

This unit looks to be in quite a nice condition but as always we will never truly know until it has arrived and can be assessed, never forget, this is EBay that we are purchasing from 😂

Something looks suspicious in the battery compartment. There seems to be contacts missing, they might be fine I just don’t know. They just don’t look right to me. There may well be some minor signs of corrosion as well. Who knows, I’ll just have to wait until the unit arrives. So let’s just be patient until then.

Come on Mr.Postman!

Assessment:

I’ve downloaded the instructions and they consist of just half of one sheet of A4. To be honest they are about as basic as are needed I guess, but in technical quality they are about as much use as an ashtray on a motorbike! And those contacts I mentioned above, look just as they were from the factory. What a strange design.

On arrival the camera appears to be in a really good cosmetic condition, there is even an old film cartridge still inside that I suspect is well fogged by now. However this will be of use if I can get it working, as it will prove if the film transport works.

The battery connectors are exactly as they were when the unit was assembled, so my earlier suspicions have come to nothing. However there are small indications of battery leakage on the outside that are always concerning, because they can always hide a greater issue occurring inside the camera. When batteries are put in place the unit is totally dead, just as advertised.

So no more to it, I have to open the unit up and see what I can find inside. Before doing that though I have connected a bench power supply to the contacts and there was still no draw on the power at all. It is definitely dead.

Repair:

On opening. Oh my word. What the heck is that? I have never seen contamination around a battery terminal like that before, the battery contacts have been totally consumed.

I could hear some rattling around inside the case and thought something had worked itself loose. No. It was what looked like broken glass, but it wasn’t, it was crystals of contamination, this camera has more stalagmites than Wookey Hole! The motor was badly contaminated and every part of the working mechanism had signs of this contamination, it was everywhere.

First things first, the issue with the power supply is purely at the point of that big mass of battery contamination on the battery terminal, there is no continuity here and this needs removing and attending to.

Using a combination of alcohol to break down the contamination, and a grinding pen, the offending crust was eventually removed. It had eaten through the wire at the battery terminal and was being held in place by the mass of crust that has built up around it. I was able to cut back the wire and re solder the terminal to make it good. There was contamination everywhere and this all had to be removed, if left in place it would cause more problems in the future. It had to be eliminated completely.

I removed the motor, and used a contact cleaner to free up its motion, I constantly turned it back and forth for about 15 minutes and I could gradually feel it freeing up. A wire had broken off from the led light on the viewfinder, this was soldered back into place and we were now ready to test. I put the batteries in and flipped the switch. I could hear the flash capacitor charging and all lights came on, I switched the unit off and began preparing to re assemble the unit, not before accidentally touching the flash circuit and taking a quick 300v shock in the hand. It’s a big capacitor as all flash units usually are. I’m an idiot, it was a school boy error. And I had a capacitor discharge unit sitting right beside me. Fool!

Ok. I’ve stopped cursing myself and the reassembly continues, and I manage to complete this with no further issues.

I’ve loaded in that old cartridge it came with and can confirm that it was all fogged film. However it has proved that the film transport system and flash are working as you can see in the video above. I’m now going to have to source some fresh film for a true test. Before that I’m going to open up the unit again and give it a good blast with compressed air and a final check to make sure I’ve got all of that contamination. It’s just the OCD coming out in me.

That said, the flash has now ceased working even though I can hear the capacitor charging up. I suspect the flash bulb has failed, so I need to get back inside anyway. Oh well, here we go again!

Like the idiot I am, I realise I have not been using sufficiently powerful batteries and the flash capacitor and flash unit are both in fine working order. I’m just going to make a small adjustment on the shutter opening switch though, and also the power contacts connected to the lens internal focus ring.

I’ve removed an unnecessary spring that was on the aperture ring, it was causing the aperture ring to sit in an opposing position to the light indicator on the side. The two of them have to match to ensure the correct exposure. The spring was pulling down on the ring, and moving it to a lower position on the indicator. Thus causing an exposure issue. I’ve removed it, it is not needed and is now working better. I have also cleaned the circuit board as I found another small patch of crystallised contamination. It’s now cleaner than when it departed the factory.

And here we have a picture where I’ve captured the flash unit working.

Now all back fully assembled I’m confident that the camera unit is in as good a condition as it could be. Fully serviced, clean and operational just as it should be. The next real test will be when I get some film inside of it to carry out some realtime tests. I’m hoping I’ll have the film within the next day or two.

Result:

I dont know why but I really love this little camera. I’ve enjoyed the challenge, the issues thrown up by it, and have gained immense satisfaction in getting it back into a working order. I don’t know if it’s the size or just the pure simplicity of having a picture to hand that is fully developed in about 15mins. The excitement of watching a picture form in front of your very eyes and even the fun factor is incredible. It’s what is needed in photography today, a step back to the 70s world of Polaroid, it’s true that back then they really knew they were on to something big, but I bet they didn’t think that it would now be having such a resurgence with the younger generation 50 years later. Instant memories preserved right in front of your eyes. The Japanese photographic industry, are so up there with modern photographic trends and demands. If only some of the now defunct big players such as Kodak who I used to work for, had gleaned such future insight, things may have been very different.

This unit as was stated earlier, is promised to a younger member of the family and that is where it will be going. I think I’m probably going to buy another damaged one to fix for myself, because I just love these little packages of fun and instant memories.

My film arrives within the next 24hrs and I’m really looking forward to getting some pictures taken.

Now all polished and cleaned and looking splendid.

The film is here and I’ve put in new batteries and tested the unit prior to putting the film in. Anyway, film installed let’s take the first picture that will remove the cover off the film cartridge within.

Now to find some subjects without wasting too much film. Picture one was of another Instax camera i am working on, bit close to be honest but there is at least an image, the camera is working. Second one is in the corner of the kitchen this comes out well. Third one is of the feral cat “Tabs” who owns our garden. She wasn’t too happy that I’d disturbed her sleep but that said it was a good photo.

Overall I’m exceptionally pleased with the results. Closer examinations shows some repeating white spots up the right side of the photos, no big deal but this probably points to some contamination on the film roller. I can’t clean this now without fogging the remaining film, so I’m happy to leave this until this cartridge has been used. I’m happy that this is the only minor issue after all the other problems this camera had.

Been a great little project that I have thoroughly enjoyed working on. These little units are great fun and the little lady that is going to get this camera is going to have a great time with it.

Another one of mass manufacturings victims, revived, and repaired and now facing a much longer and rosier future. Another one successfully kept from landfill. A winner in every sense of the word.

Many thanks for passing by, as always it is very much appreciated.
