Abstract

In electrostatographic reproducing apparatus, the developer material comprising toner and carrier has a limited useful life and must be quickly and easily replaced by the customer. The figures illustrate a white glove method for the replacement of such developer material. In Figure 1, a developer housing 10 is illustrated with two developer rolls 12 and 14 in developing engagement with the photoreceptor belt 16. To remove the developer charge in the developer housing 10, the developer housing is moved toward the reader from the front of the machine and slid along pivot/slide bar 18 until it is completely withdrawn from the machine. At that time a clear plastic bag such as illustrated in Figure 2 attached to a molded plastic frame 22 having a catch portion 24 and a living hinge 26 is placed on the top of the developer housing such that the catch portion 24 is in engagement with a lip 28 on the edge of the developer housing while the other end of the bag is held in place by means of a clip 30. Once in place the developer housing is turned about the pivot/slide bar until it is in the dump position shown in dotted line in Figure 1. The crank handle 30 is turned to eliminate carrier from the magnetic rolls and the developer material falls into the bag. The bag is constructed to be long enough that the developer housing can be rotated back in the upright position without the bag emptying. Once the developer housing is back in the upright position the bag is removed, closed by means of folding about the living hinge and disposed of. A new developer charge may then restore the machine to operational conditions.
