Most colour all-in-one machines are inkjet-based, but there's a growing market for colour laser and LED multi-function devices; one which OKI and wants a part of. Its C3530 MFP device is a colour LED printer with a flatbed scanner mounted on top a design that makes it a full 500mm deep and the best part of that high as well.
The flatbed scanner is a 600dpi device, complete with an Automatic Document Feeder (ADF) on top. It needs a magnetic catch to hold the lid down, as the entire scanner section folds to give access to the colour LED mechanism below.
Lift the lid on this and you have four image drum and toner units, mounted in a line from front to back, with a transfer belt fitted underneath and a fuser unit at the back. All these components have different service lives and all are consumables, so the machine is more complex to maintain than some of its rivals.
The printer section of the device has a 250-sheet paper tray mounted at the bottom and paper follows an S-shaped path, feeding from the front of the paper tray and ejecting from a slot at the back of the printer’s top surface. There's no optional second tray, though you do have a single-sheet, multi-purpose tray for special media, as long as it's no thicker than 120gsm.
Styled into the front of the flatbed scanner is the machine's control panel, which includes a five-line by 16-character, backlit LCD display, a number pad for the printer's fax facilities, a circular pad of five buttons and a subdivided circular black and colour copy button.
At the back are sockets for USB 2.0 and Ethernet connections; this device is network enabled as standard. There's a USB 2.0 socket at the front too, designed to receive documents scanned from the flatbed or ADF into a memory drive. This is something of a missed opportunity, as the same socket could have been used for downloading files to print, or even as a PictBridge socket to enable photo printing. It's often very handy to be able to print a document from a memory drive and can be more secure, too.
The All-in-One device is supplied with its four imaging drum and toner units already in place, though you do have to remove each in turn, take out packing wraps and replace them, before switching each toner cartridge to the unlock position. A wedge also has to be removed from the fuser unit.
OKI supplies a barrel-load of software with the machine, including both PaperPort and OmniPage in trimmed-down versions and a template manager, for corporate page templates. There's also a Colour Correct application, which is sorely needed.
