The case of the spotty slacksThe case of the spotty slacks
March 11, 2015
I was at Jan’s plant helping out with some OEE (overall equipment efficiency) issues on the packaging line. Everyone had been friendly all week, but now as I walked to the cafeteria I noticed some of the teammates looking at me funny and laughing behind their hands.
“What’s up,” I asked Jan. “Why the funny looks?”
“Look at your pants.” Jan replied.
I looked down. The front of my pants, from waist to knee, was covered with large black dots. “What the …?” I thought as I tried to imagine what had happened. Then it hit me: I’d been coded!
I had been watching the casepacker much of the morning, trying to get a handle on why it jammed. There was a large-format DOD inkjet printer on the discharge conveyor across from where I had been standing. The printer was triggering with no case and the ink dots flying across the conveyor to where I stood.
“Fiddlesticks on inky pants!” I roared. “You have your trigger photoeye set way too sensitive. Anything, like me, will trigger it from 4 ft. away. Turn it down so it triggers only when a case is right in front of it. Non-contact printers, whether inkjet or laser, should be shielded to prevent the code from going where it does not belong. In this case, a flat plate mounted on the opposite side of the conveyor will be sufficient.”
I knew I should have worn the dark pants today.
