CONSUMABLES
BERTL analysts found it easy to repair the Contex
scanner, with plenty of room for replacing circuit boards.
The main board, interface, and the power supply are on
the right side with plenty of room to access the
components.
Like any other peripheral, a scanner has consumable
parts, although they're insignificant compared to wide-
format printers’ consumables. With scanners, there are
typically three pieces that you should know about:
replacement lights, the white background plate, and the
scanner glass plate. The SD4400 series uses LED lights
that have a lifetime of approximately 50,000 hours, so they
are not really of concern. The scanner glass is also easy
for the user to replace. With the SD4400 series you can
replace the image sensors in a few simple operations.
The SD4400 series has a built-in diagnostic indicator on
the back. If all four lights are green, everything is working
smoothly. If one of the lights turns off, it indicates a failure
of one of the four board internally in the scanner, making
diagnostic faster and possible for the end user to perform.
The light indicates the status of all scanner boards,
making it easy to identify faulty boards.
Daily maintenance is simply a matter of cleaning the
document and feed rollers in the scanner.
The SD4400 series provides easy access for the
daily maintenance of cleaning the rollers.
BERTL estimated that a typical repair time is around 20
minutes.
