Your Canon LBP 840 may seem like a normal, everyday printer, but it comes from a line of printers that holds great significance in the evolutionary line of the industry. This significance can be summed in six words: Four Color Vertical In-Line Engine. You may not be familiar with this term, but you have definitely seen it if you have ever opened your Canon LBP 840 printer. It pertains to the arrangement of the toner cartridges, as this particular feature integrated four separate toner cartridges, each for a different color, in a vertical fashion. As Canon Europe describes, "The four colour toner cartridges are positioned vertically, delivering full-colour printing along the shortest possible route for a faster first print out. Maintenance and running costs are also cut considerably, as when the toner runs out you only need to change the cartridge for that colour." Today, similar arrangements can be found in many printers, but your Canon LBP 840 comes from a series of printers that were among the first to incorporate it.
