Xerox first duplicator was the 2400. This machine came on the market in october 1964. "2400" denoted the number of prints produced in an hour (40 copies in a minute). Although still some way short of offset speeds, this machine introduced the industry's first Automatic Document Feeder, Slitter/Perforator, and Collator (sorter)

My high school had one of these that was still in service into the early 90’s (or it may have been a 3600, but I can’t find a picture of one without a sheet feeder, so it’s hard to say). I distinctly remember the curved glass and there being two “humps” on the top (so I know it wasn’t a 7000). It was a basic machine, no accessories. I recall it being a darker gray color (though I may be wrong, these all look lighter than I recall), possibly with the yellow front. I don’t recall exactly when they got… Read more »


I Used to work on a copy shop with 1 like in the picture but the one we
had was 7000, it was 100% analog no transistors whatsoever.

I learned how to service it just by looking, that was 1986-1988


The 7000 had plenty of electronics in it. I was a Rank Xerox engineer starting in the late 70’s till 2000. I think the 7000 had 8 printed circuit boards mounted in the consul. Also the programmer was solid state, the counters being nixie tubes. The complexity of the electronics varied depending if the mc had a scan wheel or a variocam reduction scan system, the variocam being more complex. The 2400 original programmer had valves (tubes) in it, but was modified to have a solid state programmer in it, in the uk this was called the UK 2 programmer.… Read more »

That is true, the computer form feeder was a big beast that liked to eat it’s contents, I also remember the whole machine being incredibly noisy, I worked for a Xerox copy shop in Birmingham for many years that used solely Rank Xerox kit.

I was also a Rank Xerox engineer from 68 to 71 in Mannheim Germany and then from 71 to 73 in Durban South Africa .


Still around in SA?


I imported Xerox 2400 copiers from the USA to the UK in the early 80s and converted them to 3600 machines by changing numerous components including the main gearing. These along with the 7000 were the copier workhorse machines before the 9000 series were developed. I still have service manuals, circuit diagrams and promotional pamphlets for the Xerox 3600/7000 copiers.


Changing the gearing was only part of the problem as in the US the copier was connected to a 60Hz 120v supply. To operate in the UK several electrical components needed changing, including the large choke for the 12 fluorescent exposure lamps, plus there were cam timing changes required.


I have seen various posts here about machines catching fire, by far the worst example of this I ever saw was an 1860 plan printer which worked off rolls burn a copy which fell into the collector-tray full of plans – the whole lot then caught fire and wrecked the machine and caused our manager to absolutely freak out!!……

I used to operate Xerox 1860s, 3600s, and 7000 in the early 70’s, while in my late teens. The latter two were real workhorses; the 1860 was quirky (to be charitable). Yes, it did have a propensity to jam and ignite paper that was caught in the fuser, which would necessitate removal and cleaning of the drum, at minimum (a somewhat delicate task). Then there were the corotrons….. Come to think of it, those needed to be replaced on the 7000 and 3600 as well, IIRC. We did a lot of our own maintenance on those machines, which tended to… Read more »

I worked at Westinghouse Nuclear for 23years. I started on an 1860,which did often catch fire,especially when using vellum paper. The cure was a rag over the heating elements to catch the vapors and then periodically change the rag.I still sometimes dream of running the old girl. Setting the cortrons so they glowed with a violet aurea. Mine was on disply at the Smithsonian for years. I had written on the frame the words “a scribe”. When I looked at the one at the Smithsonian I asked permission to open the top cover. There was my writing. I also ran… Read more »

Ok guys here is some history, I worked for a company that developed soft fusing and mag-roll developer housings that we would retro fit 2400, 3600 and 7000’s All this tech was based on the 8200’s that we also rebuilt and serviced in SoCal. I got to know relay logic circuits real well back then.

Brian Frobisher

I am trying to think of the guys name that built the mag roll and soft fusing units, Mike something? Always drove a Toyota Supra as I recall.
He was a Xerox tech but then got into the after market refurbishing of these models, I remember Xerox would break the frames of the machines so they ones being sold aftermarket had the aluminum frames re-welded back together.

I also remember the green fluorescent lights made my skin crawl when making copies on the glass.
I did routine maintenance on them, changing developer, polishing drums with Xerox cotton and Brasso and other various chores.
They were amazing machines, on board air compressor, tons of relays and the cool Nixie tube copy counter.

I was a Tec Rep for Xerox from late 70’s thru the early 90’s.
I remember installing 3, 2400’s with sorters at Tuskegee
University during the late 80’s.
They were big sturdy machines with many relays, switches and moving parts.

My Dad was Office Manager for a consulting firm, and during the late 1960s, I spent summers there as Office Boy. In addition to manning the mail room, running errands and making blueprints (which were actually blue line duplicates from original drawings on mylar film), my other main task was working the new Xerox 2400 duplicator. It replaced their trusty 914. I’m pretty sure I remember accurately the Xerox tech telling me that the 2400’s paper feed was unique: instead of rubber friction rollers, which could become impregnated over time with fine paper dust and cause paper misfeeds, the 2400… Read more »

I worked as a dups. tech on 2400, 3600 and 7000’s from 1974 ti the late 1980’s

I worked at a NASA facility in 1966 and I remember when we got a 2400 used to provide copies of research papers to requestors. There was a “Key Operator” you had to call to fix paper jams or other problems. Only trained operators were allowed to use this fabulous new machine.


Ran these in Hollywood at a print shop that copied a lot of scripts, we had document feeders on them, there was an earlier version of the document feeder, and a later model. I learned how to do basic maintenance, change developer, polish/change drum, change lights etc etc etc. I remember those green fluorescent tubes made my skin crawl. Amazing machine, on board compressor for sheet pickup and fuser roll lifting.
2400 could not copy any solids, the developer was way too coarse/heavy.
Nixie tube copy counter rocked.
Great memories.


Oh, as a side note, certain companies after market sold 2400/3600 and you could tell them as they had had parts of the aluminum frames broken and they had been welded back together, you could see it plainly. Interesting.
