Nifty new printer makes the lights blink

Yep. The thing draws a lot of power when it starts up, and the solutions are a) live with it, or b) have a dedicated circuit drawn. Still flipflopping on which way to go.

Well, I’m glad you got your (unrelated) electrical problems fixed, but I just wanted validation that my original assessment was correct, and Westom was overreacting.

Is it a really sexy printer? Maybe the lights are winking.

Doubtful he inspected everything. Wires inside wire nuts without first twisting the wires together can create flicker. Many electricians consider that acceptable because copper is forgiving. If done with aluminum wire, then a serious fire threat exists.

He found defects by inspecting only what was easiest. As anyone educated in quality knows, inspection is a worst way to find all faults. Inspection can only suggest how many defects exist. Results from his inspection suggest other problems remain. But, as he suggested, the flickering is too minor; probably not be a human safety threat. Cheaper is to run a new circuit rather than inspect the many possible suspects.

Flickering also will do nothing harmful to bulbs. In fact, a slightly lower voltage due to an improper connection might lower voltage slightly - increase light bulb life expectancy.

He told of a homeowner that ignored flickering lights. That story and the threat should be well understood by every homeowner. Flickering light is not something to ignore - as the electrician demonstrated. Apparently flickering created by the printer is so minor that defects are not a threat to human life.

If flickering was normal, then running a new dedicated circuit to the printer would still cause flickering on that circuit. A dedicated circuit is to eliminate the flickering. Existing defects are not a human safety threat. And clearly not a threat to the printer. So most electricians would do no more.

You’re impervious to facts, aren’t you?

Some people buy printers because they smell so good. We call them nerds.

I could call you dumb or naive. But the purpose here is to help the OP - not appease your ego.

Well, at least I know how use Ohm’s law…

Does a human safety threat exist? Apparently not. Does a remaining defect harm the printer? No. Does minor flicker so concern you as to justify spending a $hundred? That distraction is the only reason for a dedicated circuit.
