A disposable sterile breakable vial includes a handle section and a vial section which are completely separable in response to a manually applied separation force. The new solventless process tolerates a variety of bases as co-reactants which introduces feedstock flexibility into the process while the solventless feature renders the process more environmentally friendly by eliminating volatile organic solvents from the process, reducing energy consumption, and allows shorter reaction time and workup. Numerous other aspects and features are disclosed. The characteristic measurement corresponds to criteria programmed in the image forming apparatus for determining if the toner cartridge has a full toner level or a partially full toner level. Changing the multiple bits of the first data reduces a number of the groups of bits that match any bit pattern in the first set of bit patterns.
