So I have this printer ...
Not that one specifically, that one is beautiful and in great condition, but one like it — Apple ImageWriter II. Specifically mine is the ImageWriter II/L variant, the last revision of the ImageWriter II line, but it looks like this one.
Or at least it did once upon a time.
My family acquired this printer second-hand in the late 90s along with a Mac Classic. It got used regularly for school reports and letters and business documents and tax forms for a few years until we finally were able to get a new computer with a color inkjet printer.
Long story short, like the computer that went with it, ultimately this poor printer ended up sitting in storage without air conditioning in East Texas heat and humidity for nearly twenty years. It's a sad story of slow decay.
My ImageWriter is now yellowed and scuffed and scraped and rusted and missing a piece or two; just a dim reminder of its former beauty. Given the state of it, what hope do we have of ever again hearing it sing the song of its people?
Well, I'm not going to let it go without a fight. Time to dig in and see what we can ...
... oh. Oh dear that won't do at all.
A good rule to follow when working with these 30+ year old systems, is to (carefully!) open and inspect before applying any power. In this case I'm very glad I did. Three large filter capacitors on the power supply have very obviously swollen and burst, spreading their corrosive bile all over the neighborhood.
The back side of the power supply circuit board was a wasteland of rotting solder mask, corroded traces, and displaced silkscreen. The electrolyte has eaten its way down the leads, through the solder, and left carnage in its wake all across the bottom of the board.
First order of business is getting those old capacitors removed from the board so cleanup can begin. If you've never worked with hardware of this vintage, a fair warning — make sure you're working in a well-ventilated area. Sure the solder has lead and the flux ain't great for the lungs, but the big concern here is the unholy stench of heated capacitor electrolyte hitting the nostrils like the revenge of Poseidon's refuse bin. The local fish market has nothing on these things.
The old solder, especially when mixed with the electrolyte, tends to behave in a very un-solder-like fashion. It will refuse to melt and when it does it will slump around like wet sand rather than flow like liquid metal should. While it may seem counter-intuitive, the best way to get rid of it is to add more fresh solder to it. On these single-sided boards with large components like this, a spring-action solder pump works well for getting the old parts removed, and then some solder braid will clean up the pads well.
Once the old parts are out, I like to thoroughly clean the area with isopropyl alcohol to remove the electrolyte and years of grease and dirt and pet hair that may have cemented itself to the board. In this case I also needed to use a mild abrasive to remove that damaged solder mask where it had bubbled up off the corroding copper traces. I was lucky here that none of the traces were actually broken or corroded through completely. Clear nail polish works well for protecting the now bare copper (just make sure it's not the UV-cure gel stuff).
From here I turned my attention to the case, because the power supply is the last item removed and first installed when conducting a complete tear down of this printer, and it didn't make sense to put my newly cleaned power supply into a dirty old case.
I'm not really a fan of retrobrite, and these large case pieces would be a real challenge anyway. So all I want is to clean up the dirt and rust and as many scuff marks as I can. As far as I'm concerned, the rest is just part of the history of the item. Each mark tells a story of how this item was used, not just put up on a shelf to be looked at. And if I didn't have any interest in using the machine until it completely falls to pieces, I wouldn't be bothering with going fishing replacing old capacitors.
This is a good point to do some testing. There may still be more wrong with that power supply. Output voltages could have drifted out of spec from other components aging, or maybe I installed capacitors that don't quite match the originals. The ImageWriter II/L power supply has three outputs — +5VDC, -5VDC, & +26VDC. With no load on the power supply, I measured the outputs at around ±7V and 30V. That seems high, but it's not outside of what I would expect for a power supply that's not actually driving anything. This would be a good point to use an adjustable test load, but since I don't have one of those, I'll just have to move forward with my "well it seems fine'
Spoiler: it was not fine.
As part of its startup sequence, the ImageWriter exercises all of its stepper motors to get everything to a known state. This high current draw immediately after power on was more than its old power supply could give. There's clearly more than bad capacitors on the supply, but identifying what exactly is still beyond my current skill level.
So in the interest of getting the machine working (because I have plans for it), I opted to try replacing the power supply with something more modern. The catch here is the odd assortment of voltages the original supply provided. It's easy to find a ±5VDC supply, but 26V is virtually unheard-of.
Apple's documentation for the printer mentions the +26V supply is for driving the motors. I suspected that the 26V supply was less carefully regulated and probably targeting something more like 24V. Sure enough, the stepper with the highest voltage rating on its label was 24V. With a little extra current capacity available, I figured the printer would function just fine with a 24V supply.
The catch is, 24V & ±5V is not a common configuration. There are plenty of 12V & ±5V supplies, but that won't do here. I settled on a Mean Well 24V & 5V supply with a -5V inverter ... And promptly ordered the wrong part. I had a nice new 12V & 5V supply. That's ok, once I got it in hand it was a bit too large to fit in the space I had anyway.
So I got a different Mean Well 24V supply and a separate 24V-5V DC-DC converter. It's a bit of a mess all crammed into the bottom of the case, but it should give all the right voltages (or near enough).
I did have to remove the power switch from the old supply though. That particular part has long since been discontinued, and compatible replacements proved difficult to find.
Now that it's all assembled, it's time to test. This is the part that always makes me nervous, especially when dealing with mains voltages. There's so much that can go so very horribly wrong.
I started out with a smoke test — switching on power briefly to make sure there were no direct shorts that might cause an explosive failure. No smoke is a good sign, so check the voltages. With no load, the new supply rails read 23.99V, 5.00V, and -5.55V. That's about as good as I could ever ask for. So now there's only one thing left to test … does it actually print?
Success!
It's not perfect. Every once in a while it will stutter while printing and get stuck with the carriage on one side or the other. It really needs a complete disassembly, thorough cleaning, and relubrication. That kind of mechanical teardown is a bit beyond what I'm comfortable with at the moment, but I'll happily settle for mostly working over not working at all.

#wow look something original!!#upd8z#everyone pray for my computer please. apple charged us like 500 dollars so they BETTER have repaired it#and hopefully without too much data lost

its funny how as i grew up and learned about tech, my childish preferences morphed directly into the correct behaviors and analyses of tech. i hated apple as a kid, i didnt have a reason then, but i have plenty of valid reasons now, almost all stemming from their shitty business practices. i was always a firefox user, never had a reason until chrome started demonstrating how evil a simple browser could be.
#btw i hate microsoft too! its not a a vs b thing#but apple IS more anti consumer#apple is also anti repair for IT workers#like they dont want us in IT repairing their shit they want us to buy our users new laptops for over a thousand dollars#meanwhile i can order a battery for a dell laptop off the internet for maybe 15#maybe 20 bucks?#also?? apple fucking GLUES the batteries in#so if you DO decide to pay a couple hundred just for a battery replacement kit#(yes kit because it requires a solution mixed for destroying the glue)#you get to spend all fucking day with glue hands#suction tools#and thick guitar picks#trying to get this stupid fucking macbook to relent its bad battery#i like macOS though its complicated#apple sucks but macOS is kinda sexy for some of my workflows 😔#i'd never buy an apple computer tho#i just took all my apples off the retired shelf at my last IT job#i have a mac mini#a rose pink macbook with a broken shift key#a 2013ish macbook air (its so cute)#and a 2016ish macbook pro#i paid 0 dollars for my macs
