Short version: I need a dry lubricant for use inside a laser printer and am seeking recommendations. Ideas?
Long version:
I've got a Brother MFC-L2700DW laser multi-function printer that squeals when it is printing. The usual fix is the sledgehammer manufacturer recommended approach of replacing the toner cartridge and/or the drum unit. Both of these have been replaced through normal usage. The drum unit was replaced on June 14th and the toner cartridge was replaced on June 30th. The noise persists.
I think I've isolated the problem to a metal roller bar that spans the drum unit housing. If I remove the drum unit from the printer and manually roll this roller bar it makes the familiar squeaking noise the printer makes when printing sheets of paper. While this is a good guess as to the problem, this metal roller bar is part of the overall drum unit, and as such is "replaced" each time the drum unit itself is replaced. If this is the problem area it means the squealing has persisted through a change of drum unit.
So I'm thinking a dry lubricant applied at the points where the metal roller bar contacts the plastic housing would be a good first attempt at a fix. My dad used to have a small plastic bottle with a tapered tip on it that was filled with either finely powdered teflon or finely powdered graphite. Would this be appropriate to use? Or should I consider one of the many dry lubricant sprays on the market?
Whatever I buy will be overkill as I likely will only use a fraction of a gram of the material.
