A carrier for a developer composition includes a steel core having a shape factor of 6 or more coated with a coating at a coating weight of from 0.1 to 3.0% by weight of a total core weight. The coating is most preferably polymethyl methacrylate. The steel core also preferably has an average particle diameter of 70 to 89 micrometers and a size distribution wherein 1.5% or less of a total number of carrier particles have a size less than 38 micrometers. The carrier is preferably used in conjunction with toner particles to form a developer for particular use in devices utilizing hybrid scavengeless development. Use of a carrier in such a developer in a hybrid scavengeless development apparatus enables images to be achieved with properties similar to that achieved in offset lithography.

A temperature sensitive label may be affixed to a temperature sensitive item. The temperature sensitive label conveys when the item has reached a tripping temperature. The tripping temperature may be a temperature at which the item is compromised. To convey this, the label changes properties and functions with a message to convey that the item has been exposed to the tripping temperature. For example, the label may reveal, block, or alter a message that conveys whether the item has been exposed to the tripping temperature. The message may be part of the label or separate from the label.

A method of providing prepaid billing by receiving a request for a recharge token from a customer; accepting payment information and the number of additional prints requested from the customer; receiving from the customer a unique serial number for the printing system, a current copy count for the printing system, and a remaining copy count for the printing system; generating a recharge token; encrypting the recharge token according to an encryption key stored in a first database; transmitting the encrypted recharge token to the customer; storing the encrypted recharge token in a second database; decoding the encrypted recharge token according to an encryption key stored in the second database; determining whether the decoded recharge token is valid; and where the decoded recharge token is valid, increasing the remaining copy count by the number of additional prints requested.

An electrographic printer is disclosed including a replenisher system for replenishing developer material in a development chamber by transferring replenisher from a replenisher supply source through an opening into a transporter in communication with the replenisher supply source and the chamber having a filter disposed between the replenisher supply source and the transporter to limit the size of particles passing from the replenisher supply source to the transporter. A filtered replenisher cartridge and method of supplying replenisher with a refilled replenisher cartridge are also disclosed.
