We’ve been writing about the solid-ink color print technology used by Xerox’s ColorQube printers for a long time. It’s a very interesting technology, and has a number of benefits – for instance, virtually the only consumables required are solid blocks of wax-like ink (plus a waste ink receptacle), and replacing these blocks is exceedingly easy – the user virtually just opens a cover and drops the block in its color-coded slot. Compared to many toner-based printers, replacement is very easy, and there’s minimal waste to dispose of (no empty toner cartridges), making them very eco-friendly.
On the other hand, since virtually Day One, competitors have claimed that solid-ink printers consume more energy than their laser-printer counterparts because, since the blocks of ink must be melted in order to print text and images on the page, the printer must consumer power in standby mode order to keep ink melted and ready to be used for printing, while laser printers can simply power-down.
In this test review by GNC Magazine, ColorQube Proves You Can’t Judge Green by Power Use Alone, technicians compared the ColorQube 8900X’s p energy consumption in both standby and printing modes to that of typical laser printers with some interesting results. For more see here.
