The first copier you serviced

ahhhh yes i have put hands on those as well. along with the 2550 models. im sure you remember the dial that dims the screen? customers would be like it won't come on. lol sure it will.

Absolutely. I remember the 2550 created so much fumes it would fog up the optics. They no where near as tech friendly as the Falcons (pictured)

When I got my first start in 1994. I was to new guy so I got the shite job. I had 250+ A.B. Dick 2012re's that were in all the Pantry brand gas stations all over the place. They were NOT in good shape. The company I was working for..was not a good company... But I found out that they were actually Konica 1290re's. Found actual service manuals with actual information, managed to get us access to Konica bulletins and in the end I had those little dirt balls back to running well with crisp copy, no dumpage, no fuser explosions, no service calls other than my own PM's schedule route. I have worked on older stuff though' once I became 'the guy you send when you want it fixed' and 'they guy we send when nobody else wants to step up to the challenge'. I have worked on everything from the portable 5Cpm micro copiers to the 20 foot long monstors, wide format, liquid Mitas, Mimeograph, I was there for the analog days..I could go on.

Oh, God. I had forgotten about the 7750. What a piece of shit that was.

The first machine I serviced was a 3M Casual Compact Copier "Dual Spectrum Process" It had regular type light bulb in it with a timer for exposure. If I remember correctly one copy took around 5 mins. The AI explanation of process follows. My early copier schools were Minolta ep310, Sharp 741, Savin 770/870, etc etc. I've serviced almost every one mentioned in this thread, thanks Jim Intravia Repair Guides

From Google AI:

The 3M Dual Spectrum process, also known as the Dry Photo process, was an early method for making copies using a two-step thermal process. It involved an intermediate sheet and a coated paper receptor to create black-on-white positive copies. This process was primarily used in coated-paper copiers and was known for being cumbersome and slow.


The Dual Spectrum process was a significant early development in photothermography and was used in products like the 3M Casual Compact Copier. However, it is no longer on the market, and major photographic manufacturers now offer photothermographic products using different technologies.
