Does anyone remember the big squeezy bottles of toner?
Mid 80`s, terminal working on a Vax network as admin console.. The posh printer in the lab was a kyocera not an HP IIRC.
If you filled the toner hopper then it would get clumpy and streaky while still full.
SOP became shake the toner bottle and only 1/4- 1/3 fill. No-one liked doing it as static would always leave you with a lightly dusted black pouring hand and wiping a thin film off all nearby surfaces.
Someone hadn`t tightened the lid fully, not spotted ( I was afterwards).
smacked it on the bench and grabbed hold to shake, the bottle deformed squeezing the air out with a black fog of toner, over shirt and face.
The only reflective thing in the room was the screen, didn`t look good, my line manager turned into a snigger in a suit " been coal mining have we?"
.When I got to the loo it looked like the Benny Hill/Milligan joke make up for a bomb survivor.
It took so many paper towels to rectify the airbrushed half-othello look after washing fixed rather than removed it..
Tip: take your shirt off and shake it, never scrub toner. I did.
