What is the oldest machine you currently have on contract and/or service>
You get no prizes, only the pity/awe of the rest who post here.
The oldest ones we currently have are some DC-3055"s (on contract!)

Let's keep it to Mita's for the sake of this board.

We still get an occasional DC-111, and we were still rebuilding them and selling as recently as 10-11 years ago.

There are definitely some DC-1205/1255 out there in use in our area, and we still will try to service them. In a local historical library is a Selectec copier, which is really a modified DC-2105 that was hacked-up to become a bound-book copier (operation panel relocated and front cut away to allow a book to be placed flat without breaking the binding). I think all the 152Z/1655/1785 models are finally gone so those would be the oldest here.

I still have a 1685 out there.

Still got a DC-3648 with the RU-1 roll unit. There is a 1824z that the customer separated the room with a wall and the power cord goes thru the wall.

DC-1205 that's still on service agreement for 19 years. The doctor has been "about to retire so I won't upgrade" for 10 years. I'm patiently waiting for the drum to die. Or the transformer. Or the optic motor. etc.

I have a Mita 152-Z in a used car lot...
And have a Mita 1785 in a barber shop...I cringe every time they call...Both are super cheap customers, and I am running out of bandaids....LOL

Just buried our last contracted DC-3055 so a DC-3060 is our oldest remaining and that(hopefully) should be gone next year. Once they kaff out and parts are not available from KM, we don't try band-aiding. It's not worth the pain. If I could count the times I've heard "Oh I just picked this up at an auction" Groan!

About two years ago we replaced a Sharp SF-7750 that I didn't think they would ever give up.
The customer had neatly filed away the original proposal, invoice and flyer!

It was from 1989!

Not our customer, but a tattoo artist here still uses a 3M Thermofax Model 52

I am happy that I no longer have any liquid machines out there.

Liquid! You are really dating us Techboy. I can't even stand the thought of those days. Stained hands, stained clothes, stained carpets, crappy copies.

C'mon, Skook, you don't mind getting stained, as long as it's halibut or deer stains!

Ahhh yes. Liquid machines, Canon NP 80 anyone?? how many carpets were ruined is any ones guess

OMG, the Canon NP-80, mentioned just before Halloween, what monster, now I'm gonna have nightmares!!! Liquid toner monsters ARGHH!!

Yup, they were monsters. I cut my fledgling tech teeth on those and the first mono-component machines, the venerable slider top NP 200. Ahhhh the memories...

Does anyone remember the old liquid " roll paper " copiers like the APECO or COPYSTAT. Hated those.

So glad those days are over.

Ah the fun days of black hands, and white shirts covered with black ink spots. The Savin 230 was my favorite, a roll paper liquid E-stat, it fed the paper thru a cutter, and (hopefully) cut it to size, then the paper stopped on a vacuum belt bed and was exposed ( the density was controlled by a shutter plate, a kite string attached the shutter to the cam on the density dial, rotate the dial to unwind the string and open the shutter. After exposure the copy paper was immersed in an ink/dispersant bath (literally soaked) and then ran thru squeeze rollers (like a ringer washer) and TADA a copy is born. Just don't touch it for a few seconds till it dries.

I can't believe we sold those for $3,000+ in 1970's dollars, would that be like $30,000 today?? I think I was making about $5 an hour as a tech back then.

Remingon, Apeco, SCM, Olivetti, etc., e-stats were a bear to clear paper jams. Made good money on supplies and lots of service. Black ink stained hands were the norm. I managed to keep it off my white shirts, because I ruined the suit I was married in during my first year servicing these little money makers.
