Developer unit for printer

摘要

A developer unit (44) for developing a latent image recorded on an image receiving member with a supply of particles, the developer unit including a sump (42) for storing a refill supply of particles received from a container (150) for use in the developer unit. The developer unit comprises a main cartridge body defining a sump portion (42). A fill aperture (106) is aligned with the sump portion (42) for receiving a toner refill container (150) . A guide member (116) is attached to the main body. The guide member cooperates with a corresponding member in a printing machine to position the main body in the printing machine. A stop member (120) is fixed to the guide member (116) so that when the main body is moved in a first direction (125) the stop member (120) positions the main body in a position to be refilled, and when the main body is moved in a second direction (127), opposed to the first direction, the developer unit (44) is in an operative position in the printing machine. <IMAGE>
