Reliability Features & Functions

Reliability

THE SAME HIGH RELIABILITY AS BLACK-AND-WHITE UNITS
Konica Minolta continues to build upon the formidability of the bizhub OP
multifunctional devices to bring you color-based printer/copiers that offer
the same high reliability and performance typically associated with traditional
black-and-white units.
AUTO REFINING DEVELOPING SYSTEM
The Auto-Refi ning Developing System has been implemented as a means
to maintain the developer (carrier + toner) charge at a constant level for black
& white output. This is particularly useful in those environments that output a high
volume of monochrome documents. With the Auto-Refi ning Developing System,
the carrier in the developing unit is mixed in the toner cartridge and new toner
is supplied to the developing unit as toner is consumed. The deteriorated carrier
is then collected in the waste toner box. By continually replacing developer,
it maintains an optimum charge and remains unaffected by carrier deterioration.
As a result, these bizhub devices are able to deliver stable image qualities
regardless of the print volume or environmental changes.
