Xerox 2400

Last Updated on

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)

When I started in ’78 and got trained on the 9200, the funniest stories I heard from the old timers were related to toner explosions, flaming vacuum cleaners shooting across the floor, and one poor Afican American with the classic late ’60s Afro, who, on his first day, cleaning the brush housing with the machine on, got his hair on fire, and quit immediately. (Poor guy. Hopefully he stayed in tech some way.)

Well, I don’t even remember what brought me here, but I guess I’m going down a Xerox rathole now…

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.

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.

I was a Tech Rep for Xerox from 1971 to 2000. The 2400 was the first machine that I was trained on. Brian, you are right about the 2400/3600/7000 machines inability to reproduce solids. But the problem was actually in the fuser not the developer. If you were to crash the machine while in print, you could see that the solid image was reproduced on the drum. It was solid on the paper until it got to the fuser. When it passed through the fuser it caused the toner to squash out toward to edges leaving the center area lighter.… Read more »

I have just found this site for the first time and was puzzled to discover this entry giving a totally inaccurate explanation for the hollowing out of large solid areas on copies made by the 2400, 3600, 7000 etc. copiers. This effect had absolutely nothing to do with the fuser and absolutely everything to do with cascade development. You even stated that the image on the drum or copy is visibly solid throughout if you crash stopped the machine. Well this is simply not the case, crash stop the machine and both drum and unfused copy will display the same… Read more »

Hi Mike, The 3600III had the cascade development with a set curved bias plate for solids! Hopefully you had none in GB. I had 5 of them and don’t wish them on anyone. 20lb Co2 bottles, fish line, and radiant fuser…

Hi Peter, It sounds horrific. We never had different marks of 3600’s, just plain 3600’s, some of which were field conversions of the 2400. They all had bias plates on the dev tank, toner stuck to it and had to be scraped off with a steel rule, but the type you refer to would seem to be different. I was never trained on radiant fuser machines but occasionally did calls untrained on a 2202 desk top machine. When a bonfire started in the fuser the fishing line melted and the trap doors shut. I can’t imagine why RX adapted such… Read more »

Filling solids was first solved with the 4000 copier. The developer housing used up hill cascading to solve the filling solids problem.

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.

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 »

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 »

Speaking of fires, maybe you’re not aware of another machine Xerox introduced in the 70’s (I was trained on it but don’t remember when). It was the 3600III which was basically a 3600 but had a radiant fuser instead of the heat/pressure rollers. Xerox developed the radiant fuser because the 2400/3600/7000 could not reproduce solid areas. The problem was in the fuser. The image developed as a solid but when the paper passed through the heat & pressure rollers, the solid image would end up being dark on the edges and lighter in the center. With the radiant fuser, the… Read more »

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 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.

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 do not remeber a document feed on this series; there was one that carried a web for export documentation and the tractor jobbie was the CFP with all transistor (-ve) logic – used a lot in London banks for their overnight balance runs printouts.

Hi,

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

cheers.

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 »
