摘要:
A guide is used to protect a corona cartridge during shipping and during insertion into an electrostatic marking apparatus. The guide has dimensions that will permit the cartridge to fit therein and has a locking mechanism that securely holds the cartridge in place during shipment or movement. When the cartridge is to be removed from the guide and inserted into an electrostatic marking system, a handle attached to a latch is used to free the latch from a groove in the guide. The groove in the guide is located between two upwardly protruding ramps having a slidable side and a locking side that abuts the latch and holds it in place until activation when the latch handle frees it from the groove.

A xerographic marking engine adjusts a charging actuator value, such as an AC peak-to-peak voltage or an AC peak-to-peak current, based on a determined knee value, VKNEE, of a charge curve for an imaging apparatus photoreceptor within the xerographic marking engine and environmental sensor data. The environmental sensor data may measure environment temperature and environment humidity. In near A-zone environments, for example, operational environments in which the temperature is 80 degrees Fahrenheit and the relative humidity is 80%, the charging actuator value may be selected to achieve a predetermined photoreceptor wear rate that avoids print quality defects due to lateral charge migration. In other than A-zone environments, the charging actuator value may be selected to minimize the photoreceptor wear rate, while avoiding print quality defects. The described approach allows optimal photoconductor wear to be achieved, in all operational environments, without increasing the risk of print quality defects.

摘要:
A toner-dispensing container assembly for attachment to a toner compartment cover device on an electrographic printing machine to supply toner composition to the toner receiving compartment while avoiding detachment and spillage. The toner-dispensing container assembly is fastenable over the toner compartment cover device and rotatable to a first position to open the cover to the toner compartment while the toner-dispensing container remains sealed. Further rotation of the toner dispensing container opens it to the toner-receiving compartment to dispense toner thereinto.

A cover for protecting from undesired exposure a photoconductive member assembled to the housing of a printing cartridge for use in a printing machine is provided. The housing includes an aperture periphery defining an aperture therein for communication of illumination from an illumination source with the photoconductive member. The cover includes a first portion positionable adjacent the housing, a second portion operably associated with the first portion and at least partially extendible between the illumination source and the photoconductive member for protecting a substantial portion of the photoconductive member from exposure, a third portion operably associated with the second portion, the third portion removably securable to the housing, and a fourth portion operably associated with the third portion. The fourth portion is utilized for removal of the cover. As the third portion is pulled from the housing the third portion is directed along a path spaced from the photoconductive member.
摘要:
A developer unit for developing a latent image recorded on an image receiving member with a supply of particles, the developer unit including a sump for storing a refill supply of particles received from a container for use in the developer unit, the developer unit including a main cartridge body defining a sump portion. A fill aperture is aligned with the sump portion for receiving a toner refill container. A guide member is attached to the main body, the guide member cooperating with a corresponding member in a printing machine to position the main body in the printing machine. A stop member fixed to the guide member so that when the main body is moved in a first direction the stop member positions the main body in a position to be refilled, and when the main body is moved in a second direction, opposed to the first direction the developer unit is in an operative position in the printing machine.
摘要:
An electrostatographic process cartridge detachably mountable into a cavity defined by mated machine modules forming parts of an electrostatographic reproduction machine. The process cartridge includes a housing having walls defining a process chamber and a rotatable cylindrical photoreceptor mounted to the walls and horizontally within the process chamber. The cylindrical photoreceptor has a fixed rotational closed loop path within the process chamber. The process cartridge also includes plural process components including a toner image transferring component, a cleaning component, a charge erase light component, a charging component, an imagewise exposure component, and a development component, each acting along the closed loop path for consistently producing high quality toner images. The plural components each have a critical acting position spaced circumferentially along the closed loop path, and the critical acting positions include a 234.degree. position for the toner image transferring component so as to have reliable, precise sheet feeding to an image transfer point, and a short near vertical sheet path; a 0.degree. position for the cleaning component so as to prevent any leaking toner particles from falling backwardly and down, thus contaminating image carrying sheets moving from the transfer point to a fusing module; a 96.degree. position for a ROS beam imagewise exposure component so as to form a latent image effectively with the ROS beam without undesirable curvature effects from a cylindrical profile of the photoreceptor; and a 163.degree. position for the development component in order to minimize dark decay in the formed latent image prior to its development.
