I remember when the "paperwork reduction act" came along in the 90's. People told me I better find
another line of work since copiers wouldn't be around much longer. (tech, not sales).
Every time a new government rule/law comes along, it "required" more paperwork.
Now, all the machines are pretty much multifunction devices. Print, copy, scan, fax, email.
Mechanically, they are pretty stable, but it's the SOFTWARE that can drive you nuts.
The part that ticks me off about this industry is the RIPOFF of toner/ink.
Black toner/ink is one price, but the color is 3-4-5 times more expensive. IT'S THE SAME!
Just the pigment is different.
When I'm teaching new techs in class, just to screw with them I will switch around say magenta
& yellow when they are on a break. When they come back, and make a color copy, the look on
their faces is priceless!
In troubleshooting, it's common to swap components from one color to another to see if the problem
follows the color or stays. If the toner wasn't the same, it wouldn't work. Also, if it were different,
the DRUMS would be different for each color. Same with the carrier/developer. If you are 100
miles from the office, on a Friday and the customer really really needs the machine, you need one
color of carrier/developer but only have a different color, You install it, run enough copies to run out
the wrong color in the carrier (carrier is the "super tiny iron pellets that the toner sticks to) and then
supply the correct toner, recalibrate and you are good to go.
Yeah, it's a ripoff, but it is what it is.
