Introduction of Unit Service Parts

Unit Service Parts (USP), based on the Unit Replacement Concept, are a design initiative
being introduced from the DP4580/5570/6570/8070 onwards. Image quality related items
that can cause unexpected problems have been designed as individual units so as to enable
quick and easy replacement for periodical maintenance or in the event of machine failure.
Each unit can be refilled and reused once the original supply parts have been exhausted.

The expected implementation of the Unit Replacement Concept is as follows:

1. AQuick New PM Procedure
Service technicians will carry a new set of Unit Service Parts (USP) to the user site and
replace the units and other PM parts. Maintenance time at the user site is expected to be
reduced by 40%.

2. Key Operator Replacement
One USP set will be stored at the user site. When unexpected image failure occurs, a key
operator who is trained in the procedure will replace all units. Users will not have to wait for
a service technician. Downtime will be reduced by as much as 70%.

The Unit Replacement Concept is a supplement to your service activities. The procedure for
the Unit Replacement Concept depends on your system.
