Developer unit for Color 800/1000

The Xerox 5R742 is a genuine black developer unit designed for the Color 800 and Color 1000 digital presses. It ships as a single unit per carton and works with laser print technology. This component supplies the toner carrier required for black image formation.

For high-volume mono on Color 800/1000

Print shops running the Color 800 or 1000 presses and needing black output at the rated yield will use this developer. Buyers who operate different press models or who require colour developer units cannot use this part.

2,000,000-character yield

The unit is rated for approximately 2000000 characters of black print. That yield figure is the primary measure for planning replacement intervals on the supported presses.

Questions about this item

How do I install the 5R742 developer unit in the Color 800 press, and what step is often missed?

Open the front cover, slide the unit into the black developer slot until the latch clicks, then close the cover; the step often missed is seating the latch fully so the press recognises the new unit.

What maintenance or replacement will the 5R742 developer unit need after the 2000000 character yield?

Replace the developer unit itself once print density drops or the press signals end of life; no separate components are serviced.

What limit appears first during a long continuous run on the Color 1000 with this developer?

The 2000000 character yield rating is the first limit; after that volume the developer must be replaced to maintain black density.
