1 out of 5 eggsFailing mainboards!

Pros: OKI used to be a great company with great products. Fairly easy to use with reliable components.

Cons: Failed mainboard! 5 times!!

Do not buy this printer until OKI fixed their problems. Horrible quality control!

Other Thoughts: I purchased my printers through another service. We have had to RMA the printer 5 times! OKI Techs have confirmed that there is a bad batch floating around with failed mainboards.
