Oki B840dn A3 Mono LED Printer - The Speed of Light

Launch SRP: S$1999

Design & Setup

Getting It Up and Running

To get to the fuser and toner cartridge, simply press the top cover release button located on the left of the front control panel. To remove either of them, just grab the top and pull it upwards. It’s recommended that you clean the LED array (using a clean, lint free cloth and nothing else) whenever a new cartridge is installed, or when you notice faded vertical areas in a printout.

Software installation is a matter of popping in the DVD and following the on-screen prompts; the Oki wizard will guide you through most of the steps. The Windows New Hardware wizard will start too. You can have it automatically search for the drivers, or you can point it to the correct location to speed up the process. Strangely enough, only the PCL driver was installed; we had to install the PostScript driver manually. In addition, the driver didn’t recognize the duplex unit, even after us uninstalling and re-installing the drivers several times. Eventually, we got the duplex function to work by using the drivers downloaded from Oki's website.

During our tests, we didn’t encounter any paper jam. In the case that it does occur, you’ve to rely on the LCD for status and error messages. For the most part, clearing a paper jam (be it at the input, feeding or exit stage) shouldn’t be too difficult, due to easily accessible covers. The user guide provides helpful instructions on how to clear a jam.

Body Elements

From top: USB, ACC, LAN and Parallel ports.

Extending the 530-sheet paper tray (for A3 printing) would have it jut out about 13cm from the back. Above it sits the duplex unit.

Lifting the top cover reveals the fuser unit (black contraption with handle) and the toner cartridge.

Circled in red is the LED array, which is located under the top cover.

Opening the front cover reveals a 100-sheet multi-purpose tray. It accepts paper weights up to 200gsm, and can be used for manual duplex.

The monochrome LCD can display two rolls of up to 16 alphanumeric digits. You can press the On Line button to cancel power saving mode.
