WHAT WE LIKED

Output displayed excellent print density in both copier
and printer modes.

High quality 1200 x 1200 dpi produces smooth and rich
business graphics.

Both color and monochrome output produced by the
Lexmark X792de MFP was very good. Text was bold,
crisp and cleanly formed.

BERTL photographic test files displayed realistic flesh
tones with a smooth and matte finish.

Excellent resolution in both copy and printer modes.

Very good halftone reproduction in printer mode, as the
device was able to correctly reproduce most of the
halftone shades.

Good halftone reproduction in copier mode.

Very good production of photographic images.

Output displayed very good line reproduction and
average dot control when printing BERTL's image-
quality evaluation chart.
WHAT WE WOULD LIKE TO SEE
√

BERTL was satisfied with the Lexmark X792de Color
Laser MFP's image quality. However, we would have
√
liked to have seen less saturation in some photo prints
√
and better halftone reproduction in both copy and print
functions.
