OKI B4540 Printer Review

Expert review of the OKI B4540 printer

Our Verdict:

The Oki B4540 can handle everything from copying to scanning, printing, and faxing making it ideal for a small workgroup. The optional duplexing makes sense for those who want to reduce their paper consumption, too. Its print quality is okay as it is capable of reproducing fine details, even with the default 600dpi resolution, but the poor documentation could make it difficult to learn the basic functions.

Design

This LED printer weighs 15Kg and measures 455mm tall, 520mm wide, and 445mm long. Paper is fed from a 250-sheet tray and an optional 200-sheet tray. The drum and two-piece toner units are easy to access in the front. The control panel has a two-line, 16-character display screen and an array of controls for easy menu navigation. Go and Stop buttons are easy to access, while the numeric pad is useful for entering numbers for faxing. The Oki B4540 runs on 64MB RAM, with 98MHz processing speed, and it has 16MB dedicated to page memory.

Advantages

It is easy to configure from the control panel. The Oki B4540 prints in speeds of up to 20ppm. Text documents come out looking clean and crisp on plain paper and select specialty media. The scanner can deliver files directly to a network or FTP for digital archiving, or save them in TIFF, JPEG, or PDF. The duplexer can cut paper consumption by half. The Oki B4540 has a fully featured and secure fax function.

Disadvantages

It is backed by poor documentation, which elaborates more on the fax than the other functions. Hence, users may tend to overlook the esoteric features of the Oki B4540. Slight banding occurs when scanned colour images are printed in black and white. High yield toner cartridges for the Oki B4540 are a bit expensive for a monochrome device.
