Do you think your OKI MB491 is past its sell-by date? Stop and think again. By using genuine OEM accessories you can boost the productivity and functionality of your MFP for a fraction of the cost of a new printer. Whether you want fill and forget high volume printing, fast output speeds or high definition quality, a printer upgrade is the environmentally friendly alternative to capital investment.
Have you experienced the frustration of waiting for a print only to get an error message instead? Or have you scheduled a print run for overnight only to find the whole system has frozen? Then a memory boost is a cost-effective way to bring an older printer back up to speed.
As a rule of thumb, the bigger the printer memory, the more complex the tasks your printer can handle. Having the option to upgrade memory means that your printer's performance can keep pace with the growing demands of your business without incurring the capital costs of buying a new printer.
Combined with an extra paper tray to reduce the number of refills your printer needs to accomplish any task, memory is a savvy upgrade that supports a growing workgroup by handling print tasks efficiently. OKI make it easy to boost memory with user install RAM memory modules.
For additional functionality, add the Foreign Device Interface. Control and report printing and copying through smart card systems for smooth operation and better accounting.
