Hi check out my latest dumpster find, it's a Fuji Xerox Apo Sport. Whatever on earth that means R3c 2201 for those playing along at home. And it's a gigantic A3 photocopier. And the great thing about these so they all they that they weigh a ton.

They come on the wheels. There's actually are some supports on there so you can actually you know level it out and stuff once you get it into the office. but it actually looks in really good. Nick I Believe it dates from well.

I Don't know when this one was made but it uh, it dates from like 2008 or something like that 2008 vintage and well let's pair it on and see if it works. This is not the first photocopier I've got in the dumpster. just turn the lights off there. So huh? There we go.

Alright, it's gonna work. Focus alright. here we go. Ah, conveniently the switches on.

Nice positioning. That's a really good design choice. Somebody was thinking there here we go. Cross your fingers.

Um, so although it could be like up to a decade old, it's probably not that old. but that's when the model dates from. These things usually have quite a long long jeopardy. They sell them for quite a long time.

It's not like they, you know, replace models every nine months or whatever. So anyway, mains power switched on. We'll see if it works. It doesn't seem to have like a lease thing on it, so I don't think it's like an extra lease the companies usually taken back.

ye hello we had something. Maybe the screen looks a bit. how are you doing? is it? God I Oh No Yeah, it's screen doesn't look terrific. It's there.

It's whirring doesn't I can't see a contrast pot? Come on. it's making the requisite noises. Nothing hideous as a Biograph there. Oh Yep, yet the screen is a bit washed out.

It's just my poor poor angle. Yeah well. something big. There you go.

To begin select a service, we're in like Flynn calibration. Sit up. How do you machine status Here we go. Machine serial number or IP address I Do believe it has Windows 10 drivers.

That's what it looks like on the website. Anyway, print reports hello McFly No no Maybe the touch screens gone. The screen does not look good. so maybe that's why they ditched it.

Not yeah, close doesn't work. Okay yet the touch screen touch screens died. See if it actually see four copies. typically.

get out of that interrupts. its get an old Eto a magazine. There you go just so happen a bit lying around. And and can we just do start? No, because it's copy.

There we go. Copy, we're in. We're in. We should auto paper select.

Paper Select is. Uh no. please select a paper tray. Load the following paper Auto I Whacked.

Some really annoying. Still don't know if it works or not. Oh come on. no arrow keys can't manually override this thing.

What a bummer. Well let's not muck around. let's get straight into it. There we go.

We can just take off the front panel like that. Let's got it Okay. Cable pull out conveniently? Yeah, there we go. I Could just don't screw that.

Check that out nice So we can go work on that separately. Huh? Brilliant. What a Bobby does La and we're in like Flynn. Let's check it out.

Here's our main board here. Got our backlight driver there? That could be. Well, it could be the CFL tube in there. that's going our baby.

You know you might be able to pump up the voltage of the backlight or something to compensate. But anyway, the screen still works. What we're concerned about is the touchscreen. And of course, here's the LCD ribbon going off here.

We've got all. it looks like we've got all our differs running here. Over to the LCD driver what they need. Dev pairs for that? I don't know.

but anyway, they seem to be running them and here is your touchscreen. The Foot: Classic 4 wire resistive touchscreen. We've got some discreet trainees and diodes around there, so that's rather interesting. Looks like we have ourselves a 5 pin voltage rig there, but I'm just gonna do.

Why have a little fiddle around with this measure it? make sure it's okay. You know we can get the meter on that and then play around with it and we should be able to see if that's okay and if the actual touchscreen itself is okay. like there's no breaks in the ribbon or you know anything else that's gone wrong, then we might have a look at the circuitry. Let's just have a probe around there.

half Okay. Sounds reasonable. A nice six Point Seven K Oh yeah. Okay, the great thing about this cable is that I can put it on a stand here and work.

And they've actually got voltages on the various test points here. like for example, they've got 3.3 volts here. So the supply measure that three Point Three, Three five, no workers. and there's one labeled four Point Seven five.

That's actually 5.0 one. So that actually sounds ok, like it's a five point a five volt power supply. Boy, they put four Point Seven five. that just happens to be the exact tolerance of a general five volt power supply.

So five percent lows. So maybe it's sort of like some minimum voltage. But I wouldn't worry about that. So the supply voltages are actually they look okay and they're doesn't look to be any physical damage to any other components or anything like that.

So that regulator's good, the supply rails good, obviously all the LCD driver and other our circuitry is all working fine. It's just the something to do potentially up here with the touchscreen. and if I get in there and actually measure one of the pins on the resistive input and then I touch the resistive screen. Bingo.

We've got to change. so something is changing. That's good. Um, so it should be registering at least something on the screen.

even if it was like uncalibrated out or something like that. It should be like pushing at least random buttons. Well, check out the bottom of the board here. look I'm surprised there are double sided populated this look.

They've actually waves soldered and check out the pads on there and see how it likes sort of snakes off there. It's not just directly on, that's really quite unusual. that's some sort of solder feeding type system. Anyway, you can see the glue under the components down in there.

and yeah, well, they're transistors. I've checked all the diodes on the top here and they're all okay. They all buzzed out. Looks like there's two different types of diodes in there, and the I assume that there are some sort of little mosfet e-type thing perhaps.

But yeah, it looks like this. a residue on the board. Check that out. It almost looks like this spilled something on there, but there's absolutely no damage like anywhere else.

So I don't think so. I Think that just comes from the factory light that looks like this. You know, some water or something is spilled on there, but that's just paste. Haven't bothered to clean that I Suspect Okay, sorry, but this is actually impossible to film.

I think I actually just budged in a touchscreen which had almost the same pitch on there. Think it wasn't think it was the same. preach pretty close but I had a tiny little cable but I can get my fingers under there and I was able to get the screen I put it in like the email mode or something where there are lots of different things on the screen and I was able to get it to respond to my touches. Of course it's not going to be calibrated properly for this particular resistive touchscreen or whatever, but it kind of shows that it you know the circuitry is probably working and doing its thing, so it looks like the it is possibly that faulty touchscreen on the panel itself.

Now I'm just trying to I get everything disassembled here. It's a bit of a pain, but take a look at the keys. What they have to go through to do this. Here's the here's the board.

Of course you know it's got tactile switches on there, right? but look at the effort they have to go to - that's just a oh it's just a thing to keep out spillage or whatever coming through. I Guess all sorts of crap coming through the keys. Um, you know I Guess everyone's drinking their coffee and eating their muffin around the copier machine stuff like that. Anyway, look at all the you know the intricate mouldings that they have to produce.

Okay, that's all in one big thing. but like you know, this individual button here with these little retainers. that one's a different size and a different color to this one here. I Don't think they fit? Do they know they're actually different? So the price you pay for wanting a stylish button which is slightly bigger than this one here.

they could have reused the same molding. No. God do a different one. No.

God do a different one up here for all this. I've got to do this one down here just for that one button. Like they have to design and get those manufactured. It's just you know, ridiculous effort they go to.

but I guess yeah, that's you have separate teams that do this one that you know a marketing or product design team or whatever. that actually you know designs the look and feel of the thing and then you know the poor implementation engineers have to go. Oh God. I Got to get another separate molding for that Unbelievable.

Tell you what, it's quite a bit of a convoluted system. They got some screws on the front. you have to get this front cover off first, but to do that, you've got to get the book part of the back cover off first. And it's just all rather complicated.

So yep, it's all weird. but anyway, we should be able to. Now if I can, we should be over to Whoa. Take it all this out and access the touchscreen to that.

Jeez, what a mess. Remember how that all goes back together? Okay, hopefully you can get this. I don't want to breathe but watch that I probe in like the bottom two pins there and look. look if I move this, look at that and I can actually get it to come Good.

Alright, so if I get my finger on the bottom, touch it, slide it along like that. There you go. it's changing. But if I move it.

yeah I can get it to go open. There you go. So there's definitely something wrong on here and I suspect I'll have a good look under the microscope at any like micro cracks or anything in the copper on there, but it could very well be the hot bar attachments on there. so I might be able to just maybe reheat those.

But let me go have a look under the microscope. So it just as a matter of course, one of the things I'm going to look for is any micro cracks on the copper or anything like that and that all looks okay. So so if we actually get a good resistive touchscreen this is on the back of one of these 40 systems things then we'll notice that the the way it works is exactly the same. Pins 1 & 2 have nothing.

Pins 1 & 3 have a resistance. Pins 1 & 4 have nothing but pins 2 & 4 also have a resistance so that's exactly the same as we're measuring on this one, but as you saw I think it might have some sort of you know, crack or something like that. that's stopping it from doing that. Okay, it seems to be doing the business now and if I touch it then it obvious and then it can vary.

There we go like that. so all four wires seem to now be functional. But anyway I might sort of cobble it back together see if it works Now, after a sort of like you know, heating up all those pins, maybe it was some intermittent contact that broke it that didn't get the XY coordinates required so therefore it just didn't respond there. All right, that's nicely cobbled back together should work a treat.

It's turn it on and it should all power back up. Yep. Screens upside down though all the electrons are going to fall out. sorry, you probably can't see that.

The contrast I don't think is terrific. Hey hey, it's doing stuff. Have we fixed it? Can I go near the top? sorry I don't know which orientations what? I'll try and line the screen up on here. Oh there we go.

Yep, Yep. there we go. Close got it? Yep. Copy? Yep, it's working.

Beautiful paper. select. that's the one I want if I can press Start Ah, we're on our way. It's scanning.

Oh no I didn't know the magazine in there properly. It should have copied something. Yes! winner winner chicken dinner. And yet there's no no wife user.

um, problems on there. The tone is all fused. It was a dead touch screen reheating the connections down on there. I Just used an iron at 260 degrees node.

No solder on it. That's probably like actually conductive adhesive on there rather than a reflow soldered under there. I Believe it, you know, probably just something like that. Anyway, I just heated it up and it seems to it now awoke a treat your beauty.

I'm gonna put it back together now. Doesn't mean it's still could not be intermittent or something like that. By the way, it actually came with this cable here, which goes into this empty port under the paperclip thing here. So I'm not sure actually what went under there, but it came supplied with cable then.

Okay, we'll just try it before. I put the hole back cover on and then whack it back on screen contrast Hey Winner Winner chicken dinner. There you go. turn up the contrast, turn it down.

Maybe looks a bit better down there. Save that. Ah, we're back in action. It's just like a bought one now.

Machine Status Print Reports: Here we go: Figuration, Please sleep or you want to print and press. Start Oh look at that. Beautiful. Okay, that's a configuration report.

Blah blah blah oh man. Then I Run out of paper. Okay, we want to check folks' era, history or report what kind of just display it on the screen? I don't maybe there is. and I Gotta know.

whatever. A couple of jams back in 2017 Wow What nothing. Since 2017, that's alright and 50% remaining black, 75% Cyan magenta and 50% yellow. Beautiful.

Joan and drum cartridge. or like a waste toner. All okay. Awesome.

There you go, that is like a bought one. The idea was just set to standard image enhancement and everything else, but that looks to work just fine. And today there is inside the main processor ball which just our pulls out yondu screws comes out. We've got all the memory and whatnot.

looks like we've got a yard like a separate real time clock chip. And there's the hard drive. Yes, it stores everything at copies. Apparently that's just a regular solder drive.

So yeah, when you toss these things out, you want to erase the hard drives anyway. Huge, free scalar part down in there and some custom Fuji Xerox Stuff Absolutely enormous. Like whether they're you know, custom ASIS They could very well be they these. They put a lot of engineering into these things.

Absolutely remarkable. but yeah, mm-hmm Nice huh? Ton of engineering goes into photocopies. It's unbelievable. So there you have it.

Repair Successful. Beautiful classic dumpster. fine and turned out to be a reasonably interesting repair. Just the touchscreen.

That's why they threw this thing out. They couldn't be bothered, it was probably already ten years older. Still don't know the manufacture date of this thing. Probably not that old, maybe eight years old or something and it obviously it looks like it works fine.

I Haven't tested like the ethernet and functionality and everything else, but apparently I can get Windows 10 drivers for this thing. It's got a three capability. it's got like four paper trays on the thing. absolutely amazing for color and it's a pretty reasonably modern photocopier.

What's that bracket? don't know to random bracket I think that one that was on there when I got it from the dub start. haven't tried like the feeder and stuff like that. I Don't know. maybe it could have been having issues, but the fault report was pretty good.

so it looks like it was just the adhesive, the conductive adhesive holding that flat flex strip down to the glass on the LCD and just I just hated that up. There's probably other ways to repair our stuff like that if you do that a lot and let let us know how your repair to price heated it up each one and it came good. No worries, we're not. So if you like that, please give it a big thumbs up.

As always, discuss down below: catch you next time you you.
