A method () and apparatus () control feed commitments based on feedable capacity. The apparatus may include a source () of feedable media sheets and a feeder module () coupled to the source of feedable media sheets, the feeder module configured to control the source of feedable media sheets. The apparatus may include a marking engine () coupled to the source of feedable media sheets, the marking engine configured to mark images on media sheets fed by the source of feedable media sheets. The apparatus may include a marker module () coupled to the marking engine, the marker module configured to control the marking engine. The apparatus may include a scheduler module () coupled to the feeder module and the marker module, the scheduler module configured to schedule feed commitments for the feeder module and mark commitments for the marker module. The feeder module may be configured to determine whether there will be a future low media sheet count based on comparing a predetermined number with an outstanding sheet feed commitment amount and may be configured to assert a break in feed commitments if there will be a future low media sheet count.

Apparatus and method for controlling feed commitments based on feedable capacity

A method maintains an environment within an interior of a sheet feeder during dead-cycling of an image forming device to which the sheet feeder is operatively connected. The method jets pulses of air into the interior of the sheet feeder that houses two or more pieces of media therein while the image forming device is dead-cycling. By the method, the attractive forces between two pieces of adjacent media. In a stack are reduced or minimized, and feeding of multiple sheets can be reduced or eliminated.

Method of controlling environment within media feed stack

A pneumatic sheet feeder is selectively actuable to acquire a sheet from a stack and transport the sheet towards a take-away nip. The feeder includes a feedhead having an acquisition surface substantially aligned with the take-away nip. A sensing apparatus detects three separate distances between the stack and the acquisition surface at three separate locations over the stack. The stack is then tilted based upon the distances sensed by the sensors. In embodiments, the feedhead has two sensors, and moves so that the third distance can be measured by one of the sensors. In other embodiments, the feedhead includes three sensors for measuring each of the distances.

Sheet curl correction method and feeder apparatus

A paper conditioner to control image dependent curl which uses one or more counter-rotating transfer rollers which are initially spaced from their respective back-up rollers in the intercopy gap, and which come together as the lead edge enters the nip area, and separates when the trail edge is about to pass. This permits the rollers to have a less demanding runout tolerance by bringing the rollers together when the sheet is in the nip, and then articulating the rollers apart in the intercopy gap.
