I bought this printer several months ago at a great price. When I first brought it home and hooked it up it did not work. I bought it back and got another which to my surprise did not work either. It was giving me a strange error message. I thought perhaps it was my fault, a user error. So to avoid the embarrassment of walking in the store again I called tech support.
The tech support rep walked me through the problem. There was a batch of these printers that when shipped resulted in a loose cable on the internal board itself. He walked me through unscrewing the printer, opening the back, removing a cable and securing it more tightly.
The printer worked GREAT after this. I have been using it to print mostly addresses on envelopes. The included cartridge ran out rather quickly. I assumed this was because it was just a starter cartridge. I purchased a new one which also ran out quickly. After all, I am only printing addresses on envelopes. I wondered why the ink was running out so quickly.
I decided to investigate and take apart the cartridge to see how much toner was actually left. To my surprise the cartridge was nearly 1/4 full!!!! The printer must be programmed to report "empty" when a certain amount of pages have been printed despite how much ink was used. Most printers have an option to circumvent this "quality control" feature. But not this one.
I would warn potential buyers against this printer. It prints wonderfully. But it is designed to have you purchasing toner on a regular basis. This is how printer companies make $$ now. They sell you a cheap printer and get you on toner. The cartridges are also design so that they can not be refilled. The printer knows when a particular cartridges serial number has already been used.Get more detail about C543DN Color Laser Printer.
