Earlier today I was given an hp4500 color laser printer. It came with six new in box toners, one new in box transfer roller, one 76% useful transfer roller, power cable, printer cable, and a minor problem.
There had been a MASSIVE magenta toner spill inside the printer. I'm talking PILES of toner everywhere.
So I put in on a table in the carport and grab the air compressor. I pull the toners, paper trays, fuser, tranfer belt, and everything else that isn't nailed down. And I start blasting with the air hose. A pinkish fog floats across the yard towards the neighbor's house.
But it isn't enough. You can still measure the toner inside the printer with a ruler.
Need more power.
Time to break out the commercial-grade gas powered leaf blower.
If the first attempt left me with a pinkish fog then this can only be described as a nuclear explosion of toner.
After 10 minutes (I said it was deep!) I finally have it clean. I do a little detail work the the air hose, sponge it off and reassemble the thing.
I hook it up, and after a couple of really speckled reddish pages it works like a champ!
