1.
Place the Developer Housing Assembly (new or used) to be recharged on large
piece of newspaper or cloth.
Caution
During this procedure, the Developer Housing Assembly must be
kept in a level position at all times. It is recommended the
Developer Housing Assembly be fully supported level by laying it
on something like a large piece of cloth, paper towels or styrofoam
hollowed out for the Developer Housing Assembly to lie on.
The reason for supporting the Developer Housing Assembly in a
level position is to prevent spilling toner. If new, remove the
protective cover over the magnetic roller. Do not touch the
magnetic roller.
Note
The wires are routed under and behind the right snap tab.
2.
Release the snap tabs at each end of the Developer Housing Assembly and
remove the assembly cover.
3.
Cut open the package of Developer mix. Carefully pour the entire contents of
Developer mix as evenly as possible over the two augers. Do not let the
developer mix accumulate heavily on the roller. Keep the Developer Housing
Assembly level.
4.
Reinstall the cover making sure that the rear tabs are all engaged in their
respective slots while positioning the wire harness under the snap tab. Press
firmly until you hear a positive "snap" sound for each tab indicating each snap
tab is securely fastened.
5.
Tear off the ATC sensor tag label. Peal off the protective backing, and adhere
the label to the appropriate or corresponding Print Cartridge Plate connector.
Make sure the ATC sensor tag label can be located if needed later.
Caution
It is important to re-enter the ATC value when replacing a
developer. Not doing so could result in poor color balance and
shortened developer life.
Note
The ATC sensor tag is not accessible once the developer has been
installed. Remove the label prior to installation.
