1. Problem Printers:
There always seems to be one bad apple in the bunch and in the world of laser printers there is no exception. The BROTHER line of printers is exceptional except when it comes to compatibility of their toner formulation with our foils. Years ago BROTHER changed their toner formulation to a very high temperature toner and that along with some non-plastic ingredients is the crux of the problem. Conventional toner used by all other manufacturers use "styrene" plastic (what makes the toner melt into the paper) in the mix of 9 elements that makes up toner powder. Brother went to what is believed to be an epoxy type of re-fusible material.
2. Laser Printer Settings:
There are 2 settings on your printer you want to set...
This setting normally ranges from 1 to 5 (or similar) with the factory default is the mid-range setting. When printing text and graphics you want the highest amount of toner deposited to your specialty papers. Our 'toner reactive foils' (TRF) will only transfer to toner, but... if the toner density is too low, you can get other than perfect transfers. Keep in mind that the foils transfer to the "plastic content" in the toner - one of the 9 elements that makes up conventional toner. This printer setting is normally not within your standard "printing dialog box" on screen, rather, you use the on-screen LCD display (if your printer has one) or the manufacturer's "Printer Utility" program that sends parameter changes directly to the printer.
All laser printers default to standard 20~24# bond paper. When you run heavyweight and/or textured papers through a printer, you may not get a great result because printer parameters need to set to let the printer know what it's printing on. You want to find the list of available "presets" for different weights of papers, normally listed as "Paper Types" like, Plain, Transparency, Coated, Uncoated, Gloss, Card Stock, etc. It doesn't hurt to go with the heaviest sounding paper in the list to guarantee you'll get a good dense printout that the foils will easily transfer to without any foil transfer errors. Keep in mind that you can't "re-foil" a page to correct a hiccup due to the height differences of the existing foil, so a second foil can't get down into the pits of missing foil to fix a problem. Set the printer parameters and you shouldn't ever have a foiling problem.
