Print speed and quality tests
Before mentioning the speed or quality of the C711n, I have to mention how loud it was printing. I was shocked because the C711n does everything so well; I would never have expected it to make as much noise as it did. And it wasn’t a pleasant humming but more of a machine grinding. This is the biggest flaw I found on the C711n.
When it comes to print speeds, the C711n definitely lived up to the specifications listing. It prints 36 ppm with a first page out in about eight seconds in black and white. It took just over a minute to print my entire 40 page document.
Same goes for printing color documents. Not only were the advertised print speeds on the money, but the quality was good with smooth, vibrant colors and good detail. Of course, this can be enhanced by using better quality media then the standard copy paper I used in the review.
There is both a draft mode and a toner save option in the color menu but I didn’t see a big difference between either of these modes and the normal/automatic mode I printed in during most of my black and white testing. The toner saver mode was more noticeable when printing in color so it may be worthwhile when printing interoffice documents.
I was impressed with the energy consumption on the C711n. It had lower overall spikes and a lower ready mode usage than other single function color printers I’ve reviewed in the past. I assume this is because OKI uses LED technology over the traditional laser technology.
The C711n was pulling 100 W of energy over the minute long warm up but spiked as high as 500 W. When printing, the C711n increased its energy use, pulling between 400 – 1200 W of energy during the length of the job.
When sitting in ready mode, the C711n was using about 19 W of power. When it shuts down into power saver mode, the energy use drops to about 13 W of energy.
Most impressive, however, is the deep sleep mode which draws about 1 W of power. The C711n automatically drops into this mode after a period of nonuse.
