One refill issue back to when the original laserjet/laserwriter was introduced 
was punching holes in the toner cartridge without getting plastic chips into the toner.
The toner cartridge has two compartments; one to supply the new toner, the second
is the "trash can" to hold the toner that scrapped off the drum. One trick was to
punch the primer out of a .45 auto cartridge case and mount it on a stick (or
soldering iron) so it could be heated and punched through the plastic.
