Spirit Duplicators: Copies Never Smelled So Good

Like what I make? Want fewer sponsorship ad reads? Consider contributing to my Patreon at / ourowndevices
Widely used throughout the 20th Century by schools, churches, fan clubs, and other small organizations, Spirit Duplicators or "Ditto" machines allowed small runs of documents to be copied cheaply and quickly. Often conflated with mimeographs, they were in fact a distinct technology, used a master sheet printed with dye-bearing wax instead of liquid ink. Paper passing through the machine was wetted with a solvent and pressed against the master sheet, causing some of the dyed wax to dissolve and transfer onto the paper.

Growing up in the 80's, every elementary school handout was churned out on a spirit duplicator. I remember being wowed when the school got its first photocopier and our second grade teacher showed us the crisp black output vs. the blurry purple "dittos." There would be no going back... Except there would be. There was such demand for use of the photocopier that many teachers fell back to using the duplicating machines, as they could run off their copies much faster and without having to wait for others to finish using the fancy new machine.

[@snarkymoosesshack8793]

That takes me back. When I was in grade school, it was considered a BIG THING to have the teacher ask you as a student to go run some copies off for them. I can still remember the noise of that Xerox to this day in the office. Thing was taller than I was!😅

[@jayfrank1913]

I remember cranking the handle and that heady odor! There's nothing like carcinogenic solvents to make your day.

[@m.cigledy6769]

I remember getting scolded the first time my teacher gave me a page to copy with the new Xerox machine the school just got. The old Ditto was much faster than the old Xerox machines, and I took way too long to just go to the office and make some copies.

[@Renville80]

And remember, those early copiers used liquid toner too.

[@matsv201]

When i started school in he early/mid 80s they still had that thing around. They had one xerox machine in the central office (15 minute drive away), and the teachers went there to copy up there stuff until the our school got one to a few years later.

[@CornishMiner]

That brought back some memories. Notably the odour that would emanate from the school staff room when the door was opened. A heady blend of Banda solvent, coffee, and cigarette smoke.

[@2lefThumbs]

Pretty sure my teachers *claimed* it was the banda solvent, rather than vodka they'd drunk that added to the smoke and coffee aroma😉

[@ksavage681]

They was huffing. lol

[@TheSimArchitect]

Yes! They used mimeographs at all schools I went to, though. Maybe Brazil did things differently, but the smell was quite good.

[@wornoutwrench8128]

Funny, as soon as I saw the picture, I could smell it. When I was about 7 years old, we lived in a large logging camp. If there was something going on the office would print notices and I would get paid a dime deliver to all the houses, there were no phones in the camp. Yup, a great big bag full of notices and that smell. A bunch of my friends would help me and then we would go to the commissary and buy a bag of candy with the dime. School in the 60's, all the hand outs were printed this way, Sometimes the teacher would send you to the office with the master sheet, you would wait for the staff to print it off and take back to the class. A bundle of 30 or so freshly printed sheets would almost have a damp feel to it. Man, the memories this is bringing back. Crazy.

[@denisegore1884]

Scent is one of the strongest memories.

[@nigelcarren]

In England in the 1970's my Sigourney Weaver lookalike primary school teacher Mrs Moore would say "Nigel.. would you hand out these fresh copies please!" I would melt as she handed me this warm stack of 30 sheets as her voice was such a soothing sweet caress. All these years later, I am still searching for a smooth-talking big-haired brunette lady wearing a flight-suit who smells like intoxicating solvent!!! ❤️🇬🇧❤️

[@vrdrew63]

i'm not sure if it's a mark of honour or shame to have actual memories of a machine shown on this channel. The smell of freshly printed sheets was strangely appealing to my childhood sensibilities, although at the time I didn't quite understand why. Fortunately by the time I was old enough to take my first office job they had been largely replaced by photocopier. Purple ink and the sweet smell of methanol on (slightly) damp paper arouse the ghosts of a thousand long-forgotten school tests.

I remember these machines and the scent of the prints like it was yesterday. As I recall them, these things were solidly built out of steel and were made to last for decades without any need for anything other than routine servicing. And they could be serviced by a 12 year old with a screwdriver. Can't say that about copiers today.

[@No-mq5lw]

If you have a B&W laser printer, it's very much a digitized and automated version of this machine. Part that's different is that instead of a sticking wax to a drum, it's done through static electricity and the laser creates areas on the drum where the toner will stick. Also, there's some literature although not exhaustive that say that these machines weren't exactly cheap.

[@r.duroucher225]

@@No-mq5lw Thank you for that. As it happens, I do have a B&W laser printer. I've used these printers since 1988. My last one lasted 17 years before finally giving up the ghost. Not surprised these machines weren't cheap. They were quality.

[@johnpekkala6941]

@@No-mq5lw The xerography method used in photocopiers is the same as in a laser printer. The only difference between a photocopier and laser printer is that instead of focusing an image of the document onto the drum directly using lenses and mirrors the maser printer instead use digital data combined with a laser to mark the image onto drum but the main principle xerography is used in both cases. In modern copiers this is even more obvious as they just combine a digital scanner with a laser printer instead of directly focusing the document onto the drum as with older photocopiers. This also made possible the multi task machines of modern offices that can scan, fax, print and copy in the same machine.

Back in 1975-76,I was the editor of my tiny high school's newspaper. The assistant editor and I were also the printers who churned out around 200 copies once a week. Our duplicator was manual and around about 100 copies we were giddy from the smell. I will always remember the dampness and aroma of a fresh print.

[@johnmichaelrichards]

At high school in the 1970s many of my teachers used Banda copiers. All were in purple/violet. I loved the aroma of freshly copied sheets.

[@MikeStavola]

My grade school had Ditto brand duplicators, but the lady that ran them (it was her full time job, running a handful of these for the 1000 student school) called them mimeographs.

[@SearTrip]

Our elementary school had both ditto and mimeograph machines. The mimeograph was seldom used, for whatever reason, but you could smell that ditto machine being used every time you went past that room.

[@rtod4]

My schools (1960s) called them mimeographs too, but the smell showed it was a Ditto. They sure smelled good.

[@dawnkindnesscountsmost5991]

I don't know what brand(s) my elementary and jr. high schools used (70s thru early 80s), but I remember both terms were used, and the smell was delightful. I can honestly say that I've never swallowed a drug that wasn't prescribed to me, but I can _not_ honestly say that I've never "huffed"!! All through elementary school, and possibly into jr. high school, I huffed my test papers and handouts, as did most of my classmates, despite the dire warnings of my teachers. I think my high school might've acquired a dot-matrix printer, and maybe my jr. high school did, as well, but I definitely remember the smell of the ink of those ditto/mimeograph papers.

[@bite-sizedshorts9635]

The originals were actually Mimeograph machines. They used stencils cut on a typewriter or by hand. The ink was transferred through the cutouts to the paper. Spirit duplicators used something similar to carbon paper to make a negative print on paper. Then the machine would use chemicals to transfer from that paper to the copy.

[@jacobishii6121]

Yeah,these replaced mimeographs more or less in a lot of cases had a similar end result quality wise and in appearance

[@Pythonaria]

As a 15 year old Office Junior in the early 1970s I remember the Banda machine well. We used the Gestetner more as we would print 500 or more copies of second-hand cars for sale. Often the stencils would start to split so we would patch them up with stencil correction fluid - that bright pink liquid. Our copy day was every Wednesday. The machines were kept in a small room and it was the only place in the company where I could listen to my transistor radio. Sometimes the tube of ink would burst leaving a horrible mess to clean up. Always wore an overall as that ink seemed to get everywhere even though it was quite thick. I also fondly remember the Copycat machines - one of the first photocopiers, also fluid based. We didn't have one so if something needed copying, I would be sent to the nearby photocopy shop and on the way back, pop into the bakery for the cakes for the afternoon teabreak (I'm in the UK). I'm retired now but it seems like only yesterday I was using these machines. Where did the years go?

Hi, I remember the spirit duplicators at school I believe it was a Banda product. Who would know that many years later I would work for RONEO in the R&D department. The company went through a number of changes in name Roneo Vickers, Roneo Alcatel, Alcatel Business Systems and Neopost. The company made and sold many office products and equipment but finally the sole business when I worked there was Postal Franking Machines.😏

[@m-erko]

In my 1950's/60s NSW Australian schools the generic name was also "roneo". Powerful odour memories here. There was a small coven of staff who knew the voodoo & special incantations to operate the machine. For limited copies I also remember teachers trying to use 6 or more sheets of carbon paper plus the sheets of blank paper & having to hammer the typewriter keys so hard to make it work that they punched through the top couple of blanks & carbons. Government department typewriters must have been built like farm machinery.

Around 1969 my high school got an actual Xerox machine. The teachers were excited about no longer having to use spirit duplicators, but the excitement faded quickly with the realization that a Xerox copy cost $0.25 per page (about $2.00 today). In my Senior year exams were still printed in blue ink and had a lovely aroma.

[@wilsjane]

The lovely aroma, of that 75% alcohol absorbing into your nasal passage. In fact, you were absorbing 100% alcohol and leaving the 25% behind. I wonder whether schools ever realised that they were turning their students into alcoholics.

[@bite-sizedshorts9635]

It didn't really cost 25 cents; someone just claimed it did. I was in college two years later in 1971, and copies were 5 cents. Even in the late 80s and early 90s, copies only cost 6.5 cents at the same university. If you used coins, one copy would be 7 cents and the next would be 6 cents, so 6.5 on average. I made a ton of copies, even copying entire books for scholarly research, which was one of the exceptions for copying copyrighted works. I had to copy the entire books, as I lived 5 hours from the university and had no other way at the time to do my research.

I retired as a teacher in 2018 after 30 years in the classroom. Though xerox machines were available, we were limited to ditto machines until the early 1990s because of the cost difference. Instructional materials from textbook publishers always came with ditto masters for worksheets and the like, but only had a limited lifespan-maybe 2 years out of a 7-year textbook cycle. Later on, there were Duplo machines that made almost xerox-quality copies for practically the same price as the ditto machines. The brown sheets that came with the ditto masters were perfect for use as wads for model rocketry.

I was only paying 5 cents a copy in college in 1971, so your school may have been shafted by salespeople.

Wow. This takes me back. I served in the Army National Guard in the 1980's. We had an officer in our unit who was a school teacher in a small town. When he showed up for weekend duty at the unit, he often brought in handouts that he reproduced on a Spirit machine at school. It was the purple ink with the strong aroma. Of course everyone immediately held the handout up to their face to sniff, multiple times, as they had all done when they were in school when they were kids. It was good for lots of smiles. This was in the late 1980's. We had a Xerox machine but it was expensive to operate and we had a monthly copy limit. It was easier for him to make his copies at school and not have to worry about the xerox machine.

The exact same model we had a primary school. The only thing kids used to volunteer to help with.

[@tctc0nsulting]

I was recently going thru some old papers and came across an old Ditto sheet from 1968, the poem, "Abdul Abulbul Amir" and the smell was still there. Oh, the memories that returned of Percy French's poem and that smell!

[@susanm1109]

I remember both spirit duplicators (Ditto) and mimeographs from the late 50s and early 60s. Teachers used the Ditto machine to print our exams. I worked on our school newspaper in high school and used a mimeographed for that. I remember removing the typewriter and typing on the wax stencil. If I made a typo I think there was something I could paint on the stencil to fill in the wrong letter.

[@13Photodog]

In high school (early 60s) the ditto machine was located in the school office which was in the literal middle of the school 2nd of 3 floors half way from each end. I always tried to make my way past there as soon as I got to school to see which teachers were in line to use the ditto. That was a clue to which class may have a surprise test that day.

[@flyingmoose]

I remember those from kindergarten in the mid 1980’s, they were motorized though. There were pre-made worksheets that the teacher copied, or they used a special marker to make their own. The ink was a dark purple color.

[@JoeSmith-cy9wj]

Excellent opening! I'll never forget when a teacher sent me to the office to retrieve dittos. The first thing you do is take a big wiff, and then watch every classmate do the same after handing them out.

[@martinjaramillo2429]

I remember in second grade if you were a good citizen you could churn a batch of dittos for the teacher. An honor I never achieved. I was always fascinated by this marvel of ingenuity however.

[@stephenhammonds2834]

CCL3F was also known as Freon 11. It was a CFC banned in 1995. I remember charging barrels of it into industrial chillers and thinking it smelled like those purple copies from school

[@danko6582]

Yeah, when I was a kid, all handouts were made this way. I always wondered how it worked. By the time I was old enough to figure it out, they were replaced by photocopies. Thanks!

[@NemoBlank]

I finished school in the 70's and remember the smell of those ditto's like it was yesterday.

[@larryc872]

Almost any time during class we could manage to get outside the classroom for some reason we always tried to make a quick side trip by the teachers lounge, which was usually empty because all classes were meeting at the time. Sometimes some of those masters could be found in the trash. . . . and if you were lucky it was a master of the test you were going to take later in the day!

[@JackFisherTrio]

My mother was a kindergarten teacher in the early 70’s and she used to take me with her to the office in our town to make copies. I Remember that smell and it’s caused me to smell papers my whole life like a weirdo.

[@JeffWardMusic]

Yay! Flashback! Great video, thank you for taking me down memory lane in such an informative way.

[@osseo9947]

Yes the smell! Near the end of my school days Zerox had arrived and it even had a unique oder and warmth to the fresh copied stack of paper.

[@eily_b]

We ALL sniffed the paper sheets when the teacher handed them out. And I remember the faint violet colour the print had. My Mom worked in school as a secretary and when I hung around in her office as a kid in the 80s and teachers would come in, I remember them NEVER knowing how to use it and showing those teachers multiple times how to tilt the tank and spin the crank in the right rhythm to get useful copies out of the machine. 😄I can still smell that distinct alcohol odor.

[@poofygoof]

as an 80s kid I lived through the transition time of ditto to xerox, and at least one of the photocopiers in grade school used coated paper that reminded me of thermal paper... for small runs my third grade teacher always went with the dittos, I think because she was not only older and had been using them since she started teaching, but because there was no queue and she could run off small jobs for class during lunch hour, which retained the enchanting scent.

[@CaffeineGeek]

Thank you for the memories. When I was in grade school, copies were made either with the Xerox or Ditto. All the fancy documents that went home came off the photocopier. The in-class assignments came off the Ditto. The color of choice for my school was purple. Yes, I'll admit to take a big whiff of a freshly Dittoed handout. I guess our school had a fancy one because I can still remember the ker-chunk, ker-chunk, ker-chunk as the drum rotated and copied spit out.

[@dgpsf]

Super cool to see this! Started elementary school in the very early 90s, and we still had these peculiar purple copies sometimes. I do remember being told it was something called a “ditto machine,” but I never even saw a glimpse of one, nor understood how it worked, which I definitely would have been curious about!

[@williamashbless7904]

I first entered Kindergarten in 1970 and still remember that smell. Our school staff called them Ditto Machines. If you were the teachers pet you got to help make copies. I was bestowed that honor but once. Either I don’t remember the color ability of these machines or or small school never used/could afford it. There were twelve students in my class.

[@andrebartels1690]

Thanks for the moment to return from the flashback. It was truly appreciated.

[@orangutanlibrarian]

I have been trying to wrap my head around the history of copying for a while and here it is on a plate. Thanks so much.

[@peterkutas1176]

WOW, brings back memories when I used to repair those machines for schools way, way back... I still remember the bad taste from the dust fluff from those machines; we used compressed air to blow them out.

[@loopernoodling]

I'd never heard of a mimeograph machine until I read Catch 22. In it, there was an all-powerful admin assistant, who everyone on the base had to kow-tow to in order to get stuff done - including his superior officers! Every time he came up in the conversation, someone said; '...and he has access to a mimeograph machine!'

[@billyhouse1943]

Thank you again.. very good and you do such a great job of explaining the history of and how the various “devices” work.

[@frogz]

you always post these videos late in my time zone but it is always worth being up at 1-2 am and seeing your videos before anyone else :D

[@UTleochi]

Wow, I remember those blue copies, but I hated the odour. It gave me headaches. Thank you for this fascinating walk down memory lane.

[@artyzinn7725]

its amazing that so much varied tech existed to make paper copies, going back centuries, with quality varying by price point compared to what we use today. Without spec tech, the ordinary persons access to making copies was carbon paper.

[@pfcparis]

My dad has over of these. It has been sitting in a barn for some 30 years. I figured, or was told, it was a copier, but never knew how it worked. I also remember finding the master sheets and not knowing what they were.

[@wmpmacm]

I remember these from my school days in the 1950's. Nothing like it.

[@anthonyross3495]

Lots of former school A/V nerds here, me being one. Of course I remember the Ditto machine and the smell. It was always the best part of taking a test. That scene from Fast Times was a real thing.

[@BTW...]

Ha... lasting impressions. Just seeing that machine and reading the title, I could taste the spirit aroma. Flashback right from the start. LOL Those memories from mid 60's. Then I recall the evil aroma of wetprint engineering drawings, ammonia used as a developer. Being large A1 size sheet area the smell could be overwhelming when running off a few prints. You soon enough learned why sulphur powder was kept in the drawing office. Those memories from the late 70's.

[@avaraxus]

I clicked on this and wasn't expecting the beginning after he smelled the paper LOL 🤣🤣

[@paulcarlsen4088]

This is a total flashback! I forgot about these machines from grade school through high school. Also, the smell, I distinctly remember that!😂😂😂

[@garyowen9044]

Bravo! Thank you for bring back childhood memories, and explaining one of the teacher’s black arts.

[@ntsecrets]

I remember getting dittos that were super faint probably because the wax had been used up. There was also a period where they switched to photocopiers and copied a ditto sheet and you could always tell.

[@therealchayd]

This brings back memories! As well as the smell of freshly printed sheets, I particularly remember there were always some unlucky kids in class who had the last copies the machine produced where the dye was nearly exhausted and had to share with other class members.

[@scottd9448]

How did I miss the Bander machine video? I have been having a recent conversation about these copiers. I remember being given a special task by my primary school teacher to run off several dozen copies. It was like an exciting treat to be operating the treadmill & breathing the solvent cherry and berry mix was a good buzz at seven years old! Deep breaths of the fresh prints was mandatory. I should probably watch the video first...

[@ms_enj]

Oh Gilles, that intro was tout simplement génial! 😂

[@gavinmclaren9416]

Tomorrow never knows...

[@michaelogden5958]

This copy system series reminds me of grade school where each of these methods were used. I didn't know how they worked, but they were fascinating to me at the time. Thanks for sharing!

[@billthomas8205]

Ah, the smell of my favourite teacher Mr Willis's history lessons in the Remove (1974-75)!

[@engineerncook6138]

In addition to the sweet smell of fresh ditto copies, very fresh copies felt noticeably cooler due to the evaporation of the solvent.
