Do not add toner cartridges yourself. Be gentle when using the alternate paper feed devices because they will break easily. The only thing you should attempt to do is add paper to the printer when it runs out, and you must be very careful even with this. If you use an ink-jet transparency in a laser printer, it could melt inside the printer. For all practical purposes this would ruin the printer.
Different printers use different paper and transparencies.
All the color printers produce better prints when using the special paper meant for color printers. Every printer uses a specific brand of transparency. CSM and CCV have paid for their printers and the printer supplies, and these printers are restricted to those centers. Don't use them. You won't like the consequences if you do.
