Image Quality
With the Sharp MX-7000N, users can select from three
modes: Colour, Monochrome, or Auto Colour.
The default Auto Colour mode identifies whether the
original is full colour or black and white. BERTL ran a vari-
ety of originals and the machine picked the correct mode
each time. This function is important for cost savings. While
colour click charges have come down in price, there is still
a big difference between black and white and colour click
charges. Picking the wrong mode could result in an addi-
tional expense for the end user.
The device comes with Text, Text/Photo, and Photo
modes to allow the user to capture and reproduce differ-
ent image types. BERTL's testing included all three modes
with a wide range of copy originals to look for the device's
strengths and weaknesses.
The monochrome mode reproduced images and half-
tones very well and reproduced text accurately, consistent
with Sharp's monochrome MFP line.
In monochrome Text mode, text was sharp down to 6
points. Images had increased contrast, but still reproduced
well.
In monochrome Text/Photo mode (typically the default
mode), text and lines reproduced well with accurate repro-
duction down to 6 points. Images were recognizable and
reproduced with less contrast, creating a more pleasing
reproduction for images.
The monochrome Photo mode uses a halftone rendering
algorithm that produces high quality reproduction of pho-
tographs. In Photo mode, text did not reproduce as well.
Photo images reproduced very well.
Overall the Sharp MX-7000N has an excellent rating and
performed better than the norm. This business colour MFP
could even compete on many levels with a graphics colour
device.
It appears that Sharp's switch to laser technology, as op-
posed to LED, has made a big impact in quality for the best
with its MX line.
Results of colour reproduction in Text, Text/Photo, and
Photo appear on the next page.
