摘要:
A printing device includes at least one printing engine that comprises customer replaceable units. At least one engine controller is operatively connected to the printing engine, and the engine controller uses software to control operations of the printing engine. At least one non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. Additionally, at least one adapter card is operatively connected to the non-volatile memory and to the customer replaceable units. The customer replaceable units each comprise a memory unit. The adapter card reads incoming print jobs before the print jobs are delivered to the controller and the adapter card accumulates and stores statistics relating to print jobs within the memory unit of the customer replaceable units. The adapter card passes the incoming print jobs to the controller in an unaltered manner.

A printing device includes at least one printing engine that has many sensors (first sensors and second sensors) and at least one engine controller operatively connected to the printing engine. The engine controller uses software to control operations of the printing engine. Also, at least one non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. At least one adapter card is operatively connected to the non-volatile memory and to the first sensors and second sensors. The first sensors correspond to the design of the controller and are items designed as original equipment of the printing device. To the contrary, the second sensors correspond to the design of the adapter card and are items designed to be installed in the printing device after the printing device is in post production, customer service. The adapter card receives feedback from the first sensors and the second sensors and the adapter card reads and modifies incoming print jobs before the print jobs are delivered to the controller.

A printing device includes at least one printing engine that has actuators and sensors. At least one engine controller is operatively connected to the printing engine, the engine controller uses software to control operations of the printing engine. At least one non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. Further, at least one adapter card is operatively connected to the non-volatile memory and to the actuators and sensors. The adapter card stores data and receives sensor feedback from the sensors. The adapter card uses the data and the sensor feedback to control the actuators by bypassing the engine controller when communicating with the actuators. The adapter card provides adapter card feedback to the non-volatile memory.

An apparatus (100) and method (200) for print apparatus rotational assembly cleaning blade adjustment is disclosed. The apparatus can include a printer rotational transport assembly (110) configured to transport a substance in a printer. The apparatus can include a cleaning blade (120) coupled to the printer rotational transport assembly and a cleaning blade sensor (130) coupled to the cleaning blade, where the cleaning blade sensor can be configured to sense cleaning blade stress condition information. The apparatus can include a controller (140) coupled to the cleaning blade and the cleaning blade sensor, where the controller can be configured to adjust cleaning blade parameters of operation based on the sensed cleaning blade stress condition information.
摘要:
A printing device has a printing engine that is at least partially made up of a customer replaceable unit or units. An engine controller is operatively connected to the printing engine. The engine controller uses software to control the operations of the printing engine. A non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. An adapter card is operatively connected to the non-volatile memory and to the customer replaceable units. The customer replaceable unit has a memory unit and the adapter card reads data from the memory unit. The adapter card uses the data to directly alter values within the non-volatile memory by bypassing the engine controller when communicating with the non-volatile memory. Further, the adapter card alters the non-volatile memory without altering the software used by the engine controller.

A method for minimizing cross-process non-uniformities in solid and heavy shadow regions of printed documents is provided. The method includes marking with a marking engine an image on an image bearing surface moving in a process direction; generating profile data of the image by sensing an optical characteristic of the image in a cross-process direction; adjusting at least one control actuator of the marking engine so as to shift the characteristic of a subsequent marked image in the cross-process direction to at least a target value; and generating a spatially varying tone reproduction curve to smooth the characteristic of the subsequent marked image towards the target value.

An apparatus and method that cleans a photoreceptor in a printing apparatus is disclosed. The method can include setting a voltage bias of an electrostatic cleaning brush in a printing apparatus to a first voltage bias. The method can include generating an image on media using a photoreceptor. The method can include cleaning the photoreceptor using the electrostatic cleaning brush operating at the first voltage bias. The method can include measuring operating conditions of the printing apparatus to determine an expected film accumulation rate on the photoreceptor. The method can include adjusting the voltage bias on the electrostatic cleaning brush to a second voltage bias based on the measured operating conditions.
