Manual of product MC851dn
Editorial note
The OKI MC851dn printer stands out for its impressive printing performance, reaching up to 34 pages per minute in black and 22 pages in color. This speed makes it an ideal choice for demanding work environments where efficiency is paramount. Its laser printing technology also ensures optimal quality with a maximum resolution of 1200 x 600 DPI, delivering precise and vibrant results. However, this device has some notable drawbacks. Its weight of 68 kg can make moving and installing it difficult, especially in offices with limited space. Additionally, the lack of Wi-Fi connectivity limits usage flexibility, requiring cabling to print from mobile devices or other computers. While the printing speed is satisfactory, the 90-second warm-up time can be a disadvantage for those who need immediate printing. Finally, the cost of consumables, such as toners and drums, can be high, thus increasing the long-term operating cost. On the features side, the OKI MC851dn offers good flexibility thanks to its advanced scanning capabilities and a 400-sheet input capacity, which reduces the frequency of reloading. However, the size of the built-in screen could be improved to facilitate navigation through settings and options. In summary, the OKI MC851dn is a high-performing printer that meets the demands of professional users, but certain aspects, such as its weight and the cost of consumables, should be considered before purchase.Score details
