摘要： A replaceable printer component having an integral memory for use in a printing system includes a semiconductor die and a plurality of circuits formed on the semiconductor die. Each circuit is associated with and indicates the state of a bit in the memory. The memory stores a plurality of functional bits that must match values expected by the printing system for proper operation of the printing system. The memory stores a plurality of informational bits that are not critical to proper operation of the printing system. A large percentage of the circuits associated with the functional bits are positioned substantially near a center of the semiconductor die.

摘要： A system and method for detecting an error in data received from a memory of a replaceable printer component includes providing a first parity bit associated with a first data item. The first data item and the first parity bit are stored in the memory. The printer includes a plurality of electrically conductive lines. The memory includes a plurality of bits. At least one of the electrically conductive lines is associated with each bit. The first data item and the first parity bit are read from the memory. An electrical test of at least one of the electrically conductive lines is performed. An error in the first data item is identified based on the first parity bit read from the memory and the electrical test.

摘要： In one embodiment, a drop detection method includes: moving a light source along a first side of the drop zone to illuminate drops passing through a drop zone; and, without blocking any part of the drop zone, detecting light scattered off the drops as the drops pass through the drop zone. In another embodiment, a drop detector includes: a light source on a first side of the drop zone for illuminating drops passing through a drop zone; a light detector on the first side of the drop zone near the light source and a movable carriage carrying the light source and the light detector. The light detector is exposed to the drop zone for detecting light scattered off drops as the drops pass through the drop zone. The carriage is movable along the first side of the drop zone in a direction transverse to the drop direction.
