A heat and pressure fuser for fixing toner images to substrates. A dual heating lamp arrangement is utilized for elevating the surface temperature of a heated fuser roll. The operation of the dual heat lamps is controlled using dual thermistors for maintain steady state temperature fluctuations to .+-.3.degree. F. The thermistors are positioned, one adjacent the inboard end of the fuse and the other adjacent the outboard end thereof. The outboard thermistor is used to determine the desired on time of the fuser lamp and the inboard thermistor is used to determine which of the two lamps is on. If the inboard temperature is below a predetermined target value a 14 inch lamp is turned on. If the inboard temperature is at or above a predetermined target value an 11 inch lamp is turned.

An apparatus, method and system are provided for carrying and dispensing an ink into a printing system. A system configured to dispense an ink comprises an ink carrying apparatus having a container, a movable cover, a unit monitor, a film, and a locking tab. The system also comprises a docking station configured to accept the ink carrying apparatus and engage the locking tab when the movable cover is in an open position. The system further comprises a processor configured to communicate with the unit monitor to facilitate a movement of the movable cover from a closed position to the open position. Based on a detection of a type of ink in the container, the movable cover is allowed to be moved from the closed position to the open position so as to facilitate removal of the film and cause the ink to be dispensed.

A toner transport apparatus for electrographic printing machines that uses the distance between a toner storage container holding a supply of toner material and a developer housing to admix the toner with the developer. A first flexible auger transports the toner from the toner storage container to the developer housing and a second flexible auger transports some of the toner and developer from the developer housing back to the toner hopper where it is mixed with fresh toner.

According to aspects of the embodiments, there is provided methods of replenishing at least one consumable in a printer system having at least one channel with a lockout device and an indicator. The embodiments incorporate a solenoid latch on the channel, a channel closed switch and an attention light. When a consumable needs to be replaced, the user scans the new consumable label against a CRUM reader. If it is valid consumable for the printing system, the attention light above the low or empty channel is lit and its solenoid latch is released. The attention light and solenoid latch would be wired in parallel so that whenever the solenoid is energized to allow the channel to be opened, the attention light will illuminate.

An ink jet printer has a sheet conveying and drying device having a plurality of flexible, resilient yet stiff fingers connected in a cantilevered manner to a drive chain which moves the fingers from a printed sheet receiving tray to a sheet stacking tray. After sheets are printed by a conventional ink jet printing head, the sheets are picked off of the printed sheet receiving tray and fed to a sheet stacking tray. The printed sheets are dried while being fed from the printed sheet receiving tray to the sheet stacking tray. After the printed sheets are picked off of the fingers at the sheet stacking tray, the chain drive continues to move the fingers in a counterclockwise direction along the chain path. The resilient, flexible fingers are deformed by upper and lower guide rollers, a stacking tray and a rear separating wall and are flicked back into a sheet receiving position at the printed sheet receiving tray. The speed at which the chain drive moves the fingers can be varied to ensure that the images are dried by the time they reach the sheet stacking tray.

A release agent management system incorporated in an electrophotographic printing machine having a heat and pressure fuser assembly. The fuser assembly includes a heated fuser roll, a pressure roll and a wick for applying fuser oil to the surface of the heated fuser roll. The wick is moved into and out of engagement with the fuser roll and release agent material is supplied to the wick in accordance with the number of prints fused from which a print equivalency value is calculated. The print equivalency corresponds favorably to actual oil consumed. A predetermined print equivalency value is used for determining when oil is supplied to the wick.
