PRINTING SYSTEM AND WRITING MODULE THEREOF
A printing system is disclosed which comprises a writing module, and a member having an imaging surface configured to carry a polymer and movable relative to the writing module. The writing module is configured to direct onto the imaging surface a plurality of individually controllable light beams that are spaced from one another in a direction transverse to the direction of movement of the imaging surface, incidence of a light beam on a spot on the imaging surface serving to soften or liquefy the polymer carried by the imaging surface at the spot. The polymer softened or liquefied at the spot can transfer to a substrate or serve as an adhesive on the imaging surface. The writing module comprises a plurality of integrated electronic modules each having an array of individually controllable light sources, each light source producing a respective one of the light beams. In the invention, each light source comprises at least two Vertical-Cavity Surface-Emitting Laser (VCSEL) light-emitting semiconductor junctions connected in series with one another and configured to direct light onto the imaging surface at the same spot as one another.

Transfer member for printing systems
There is disclosed a layered article that can be used in indirect printing, in analog or digital processes. The layered article, when configured as a transfer member, may serve to receive an ink in any form, allow the ink to be treated so as to form an ink image, and permit the application of the ink image on a substrate. The transfer member comprises a support layer and an imaging layer, which may be formed of a silicon matrix including dispersed carbon black particles. Methods for preparing the same are also disclosed.
Shift circuit operating by using a capacitor, a printing head and printing device thereof
A shift circuit operating by using a capacitor, a printing head and printing device thereof. The shift circuit includes a power signal line, a grounding signal line, a first shift signal line, a second shift signal line, a plurality of diodes, a plurality of grounding resistors, a plurality of thyristors, a cascaded resistor and a capacitor. The capacitor connects between the gate of the first thyristor and the first shift signal line. Therefore, the capacitor is charged during the off time of the period of the first clock signal, and starts to be discharged from an edge between the on time and the off time of the period of the first clock signal. During the on time of the period, the capacitor is fully discharged. Such that, the gate voltage of the first thyristor is sufficient to turn on the first thyristor and will not affect the following shift action.

Image forming apparatus including a moving mechanism for an optical print head
In an image forming apparatus, a cover 558 rotates from an open position to a closed position, so that an urging portion 561 urges a first portion-to-be-urged 566, and a slidable portion 525 moves from a rear side toward a front side. By this, an optical print head 105 moves from a retracted position toward an exposure position. Thereafter, when the cover 558 further rotates, the urging portion 561 moves from the first portion-to-be-urged 566 onto a second portion-to-be-urged 567 and moves on the second portion-to-be-urged 567. By this, the slidable portion 525 and link portions 651-654 are kept in a rest state without being moved with rotation of the cover 558.
Thermal conduction transfer printing
A printing system is disclosed for thermal transfer printing onto a surface of a substrate. The system comprises a transfer member having opposite front and rear sides with an imaging surface on the front side, a coating station at which a monolayer of particles made of, or coated with, a thermoplastic polymer is applied to the imaging surface, an imaging station at which energy is applied by a thermal print head via the rear side of the transfer member to selected regions of the particles coated imaging surface to render particles coating the selected regions tacky, and a transfer station at which the imaging surface of the transfer member and the substrate surface are pressed against each other to cause transfer to the surface of the substrate of the particles that have been rendered tacky.
Light emitting component, print head, image forming apparatus, and light irradiating device
Provided is a light emitting chip C including: a substrate 80; light emitting elements each having one terminal connected to a predetermined reference potential and the other terminal, the light emitting element having a rectifying characteristic; and thyristors each connected in series with the other terminal of the light emitting elements, respectively, the thyristors being configured to make the light emitting element connected thereto emit light or increase light emission amount of the light emitting element when the thyristors turn on in an ON state.
Image recording apparatus and image recording method
An image recording apparatus that irradiates a recording target with laser light and records an image thereon, that includes: a laser irradiation device that has plural laser emitting elements, and irradiates the recording target with laser light emitted from the plural laser emitting elements; an irradiation condition adjusting unit that causes the laser irradiation device to emit laser light such that a part of an image dot recorded on the recording target moving relatively to the laser irradiation device overlaps an image dot adjacent thereto, and makes a laser irradiation condition for when image dots forming a boundary between a colored portion and a non-colored portion are recorded, different from a laser irradiation condition for when the other image dots are recorded; and an output control unit that controls the irradiation with the laser light, based on the laser irradiation condition adjusted by the irradiation condition adjusting unit.
