Abstract

When a xerographic copier is moved or transported, the housing may tip or shift resulting in the developer material shifting or leaking out of the developer housing. Three remedies to this problem are presented with reference to Figures 1-3. Referring to Figure 1, a toner cartridge 8 is shown in relation to a portion of a copier developer housing 10. Prior to movement of the copier the user installs bar magnets 12,14 along the length of the housing which are typically of aluminum construction. The magnets magnetically capture the loose ferrous developer material within the housing in a stable position during transport Once the machine move is completed, the bars are removed and stored.

MAGNETIC RETENTION OF DEVELOPER DURING COPIER TRANSPORTATION( Cont'd)

When a xerographic copier is moved or transported, the housing may tip or shift resulting in the developer material shifting or leaking out of the developer housing. Three remedies to this problem are presented with reference to Figures 1-3. Referring to Figure 1, a toner cartridge 8 is shown in relation to a portion of a copier developer housing 10. Prior to movement of the copier the user installs bar magnets 12,14 along the length of the housing which are typically of aluminum construction. The magnets magnetically capture the loose ferrous developer material within the housing in a stable position during transport Once the machine move is completed, the bars are removed and stored.

Figure 2 shows a cartridge 20 containing a removable magnetic assembly 22 that would replace the toner cartridge within the machine. Assembly 22 would magnetically capture the loose developer material within the housing prior to moving the copier. The copier then would be moved with this magnetic toner cartridge in place, holding the developer material in a stable position during transport. This cartridge is open on the top surface along its length, allowing the magnetic assembly to be removed while the cartridge is still in place withi...
