I worked as support for a the Certification & Compliance/Quality Assurance Unit for the State of Alaska. During my time there the repair techs for the copiers and other equipment were gracious enough to give me lessons in reading codes and handling a variety of basic issues. They also helped me understand which codes were necessary to call repair for and which I could fix.
When I started the copiers were very old and not under warranty as well as continuously breaking down as a result there were many calls for repair which were roughly $400-600 per visit plus parts.
I spent an afternoon once fixing 3 of the same old model copiers. After I had exhausted my knowledge and every trick I could Google I informed Admin that copiers would get 3 tries for me to fix them and then I’d have them call for repair. They were shocked that I’d been willing to work so hard to keep the office running and readily agreed to my three strikes rule. I saved the state thousands of dollars because I was willing to take the time to patiently work out issues and fix as many things as I could.
The latest copier was under a warranty lease and repair calls were no longer expensive however were still some old copiers and other older equipment in the building and the techs still sought me out to see what I might know and especially if I knew where the latest stash of supplies might be.
