摘要:
A device for displaying an exchange message for a process cartridge installed within a body of an image forming apparatus informs a user when the process cartridge should be replaced. The process cartridge, which can be installed within and removed from the body, combines a photosensitive drum, a cleaning blade and a waste toner receptacle as a unitary structure. A display provides the user with predetermined messages. A video controller receives a print command from a host computer and controls a printing operation by increasing an internally stored sheet printing index value by one in response to each printed sheet, and enables output of a message indicating that the process cartridge should be exchanged through the display when the sheet printing index value is greater than a predetermined value.

An image forming device using an engine for performing a print operation, an engine controller which determines the state of the engine and generates an engine state signal, and a video controller which receives the engine state signal and determines whether data transmitted from a computer is to be received or not based on whether the engine state signal is indicative of a normal state, an abnormal state which can be recovered from, and an abnormal state which can not be recovered from. Data to be printed is received from the computer when the engine state signal is indicative of a normal state and an abnormal state which can be recovered from; data to be printed is not received from the computer when the engine state signal is indicative of an abnormal state which can not be recovered from. Received data is changed into bit map image, and during a normal state or when the abnormal state of the engine is completely recovered from during check of the engine state, the bit map image is output to the engine for printing.

A device for informing whether fresh toner should be newly supplied into a developer (20) into an electrophotography machine comprises a sleeve (22) for delivering toner (29) to a photosensitive drum, a blade (23) for regulating the distribution of the toner deposited on the sleeve (22), an agitator (24) for agitating the toner, a hopper (21) for loading the toner, a lever (25) with an upper projection (26) and lower support (27) pivotally moved with a pivot pin (25') attached on an inside wall (21') of the hopper (21) towards the sleeve (22), a metal plate (28) supported by the lower support (27), an actuator (32) with a magnet (36) and light shield (34) pivotally moved with another pivot pin (35), and a photosensor (31). Wherein, if the hopper (21) is devoid of the toner by consuming, the magnet (36) is attracted towards the metal plate (28) so as to cause the light shield (34) to block the photosensor (31).

An LED printer constructed with a lower body frame, an upper body frame, a process unit having an upper leading end for mounting a photo-sensitive drum in a housing, an LED frame for supporting an LED head array beneath its right end portion, a pair of through holes formed adjacent to the right end of the LED frame, a pair of blind holes formed on the LED head array facing and aligned with the pair of through holes, and a pair of threaded bolts respectively received by the pair of through holes for connecting the LED head array to the LED frame by respectively fixing the lower ends of the pair of threaded bolts in the pair of blind holes. A pair of compression springs are interposed between the LED frame and head array and enclose corresponding ones of the pair of threaded bolts in order to exert a resilient force on the LED head array. A pair of LED positioning plates formed on both upper side ends of the housing. When an image process unit is installed inside the upper body frame, the upper leading end pushes the lever so as to pivot the LED frame together with the LED head array clockwise, so that both lower side end surfaces of the LED head array respectively contact the pair of LED positioning plates under the resilient force of the pair of compression springs and thus the gap between the photo-sensitive drum and LED head array is properly established and maintained.

An LCD device provides enhanced display quality. An insulating layer is formed on a first substrate. The insulating layer covers the contact portion of a switching device in which the switching device is electrically connected to a transparent electrode and has an opening for exposing a portion of the transparent electrode. A reflection electrode is electrically connected to the transparent electrode through the opening. The insulation layer covers a first portion of a driving circuit formed on the first substrate. A sealant is interposed between the first and second substrate to engage the first and second substrate and to cover a second portion of the driving circuit. Therefore, the driver circuit may operate normally, and the distortion of the signal outputted from the driver circuit may be prevented.
