For reprographic work, fast LED printers require fast monochrome scanning,
while color printing is less demanding. The HD4230 is designed to supply
the speed and image quality required for both.
Combining advanced imaging technology with industry-leading know-how,
the HD4230 gives picture-perfect color scans and copies every time –
simply.
Whether it’s large color posters, architectural sketches, detailed maps or
drawings, the 42” imaging area can handle them all – with the high
resolution and accuracy you expect from Contex scanners.
You can depend on the HD4230 for unmatchable full color and monochrome scans
– at speeds you won’t believe!
