Do you own an OKI B4520/4540 that no longer meets the needs of your growing office? Before you send your printer for recycling, there's a quick, easy and cost-effective way to rescue your MFP. It drives down capital and operational costs and reduces your environmental impact. By adding original accessories you can have your OKI printer back up and running better than ever in minutes.
OKI accessories are easy to use because they simply slot, click or slide into place. That means you won't need to employ a technician to boost the productivity of your printer. Just power down your printer and lock your additional paper trays in place using OKI's innovative twist and click trip over protection.
Once in place, one or more paper input trays will boost your workforce's ability to deal with high volume printing. You won't need to keep reloading your printer throughout the day, saving you time and boosting productivity. Different trays can also be used specifically for different sizes or weights of paper. That's why additional paper trays are the savvy way to meet the changing print needs of your office.
You can also add the functionality of duplex print in seconds. Slide the unit into place and start double sided printing which gets jobs done fast and halves your paper bills at a stroke. Your printer also uses less energy for lower operational costs. These upgrades can all be achieved for less than the cost of an entry level business printer.
