Embodiments described herein relate to an inkjet service station and methods of servicing an inkjet printer with the inkjet service station. The inkjet service station is disposed in an inkjet printer of an inkjet chamber. The inkjet service station is operable to perform servicing operations on a processing apparatus of the inkjet printer. The servicing operations include at least one of printhead spitting, printhead purging, printhead flushing, printhead cleaning, printhead drying, or vacuum suction.

A discharge apparatus includes an ink accommodating unit that accommodates a clear ink, a discharge head including a nozzle configured to discharge the clear ink to a print target, a heating unit configured to heat the print target, and a wiping member configured to wipe a nozzle-formed surface of the discharge head including the nozzle. The clear ink includes water and resin particles having a volume average particle diameter of 50 nm or less. A dried film of the clear ink has glass transition temperatures (Tg) at 50 degrees Celsius or higher and at lower than 0 degrees Celsius.

A printing device includes: an inkjet printhead; a lift mechanism for raising and lowering the printhead through a lift path; and a pivotally movable spit flap positioned in the lift path. The spit flap is configured to swing away from the lift path when the printhead contacts the spit flap during lowering of the printhead.

A modular service station for servicing at least one inkjet printhead of an inkjet printing system, the service station comprising: a frame with mounted thereon at least one capping element and at least one wiping element, a means for horizontal movement of the at least one inkjet printhead between a printing position and a servicing position, the means for horizontal movement configured to enable a wiping process, a means for vertical movement of the at least one inkjet printhead, the means for vertical movement configured to enable capping, unclogging or purging processes in respect to the at least one inkjet printhead, and a waste ink tank in hermetic communication with the at least one capping element. A method of servicing an inkjet printhead of an inkjet printing system is also disclosed.

According to one embodiment, a cleaning device comprises a suction port portion, a guide portion, and an urging member. The suction port portion is configured to face a nozzle plate of a liquid discharge head at a predetermined gap distance between the suction port and the nozzle plate. The guide portion is configured to face a cover mask of the liquid discharge head and is moveable in a direction away from the cover mask. The cover mask covers a periphery of a surface of the nozzle plate. The urging member is configured to urge the guide portion toward the cover mask.

The ratio of the rotation speed Nr of the take-up roller (take-up rotation speed) and the rotation speed Nu of the feeding roller (feeding rotation speed) is used. That is, knowledge that the roll diameter Drr of the sheet S taken up on the take-up roller is given by a function using the ratio of the rotation speeds Nr and Nu as a variable was obtained. Accordingly, the roll diameter Drr is computed from this ratio.

A recording apparatus includes a print head, a recovery unit, a type obtaining unit, a threshold obtaining unit, and a calculation unit. The print head forms an image by applying a recording material to a recording medium. The recovery unit performs a recovery operation for recovering an ejection state of the print head. The type obtaining unit obtains a type of the recording medium on which the image is to be recorded. The threshold obtaining unit obtains a threshold for performing the recovery operation corresponding to the obtained type of the recording medium. The calculation unit calculates a count-up value by adding, in response to recording on the recording medium, an addition value set for each of types of recording media. The recovery operation is performed in a case where the count-up value calculated by the calculation unit exceeds the threshold obtained by the threshold obtaining unit.

There is provided a cleaning device for a liquid jet head which can efficiently clean a jet plate attached with a guard member while preventing cleaning liquid from being leaked along an opening of the guard member. The cleaning device for the inkjet head includes a holder moving relatively to the inkjet head, wherein the holder includes a jet section for jetting the cleaning liquid toward a nozzle guard of the inkjet head, a wipe part which has a width in a width direction perpendicular to a moving direction of the holder smaller than a width of an opening of the nozzle guard, and which wipes a nozzle plate due to a movement of the holder, a first suction section disposed ahead of the jet section and the wipe part in the moving direction of the holder, and a second suction section disposed posterior to the jet section and the wipe part in the moving direction of the holder.

A thread-coating system includes: a thread-coating module having a droplet ejector assembly; a thread gatherer positioned upstream of the thread-coating module and configured for arranging a plurality of threads in a thread wall; a thread expander positioned downstream of the thread-coating module for receiving a coated thread wall and expanding the coated thread wall into individual threads. The thread gatherer is configured for adjusting a spacing of threads in the thread wall and an overall height of the thread wall via a pivoting motion.

A maintenance method for a liquid discharging apparatus including a liquid discharging head. The liquid discharging apparatus executes a printing process including a discharging process in which the liquid discharged from the liquid discharging head lands on the medium, and a maintenance process in which the liquid is discarded from the liquid discharging head. The maintenance method includes: counting a unit period number, which is the number of ended unit periods among a plurality of unit periods obtained by dividing a period required for the printing process in accordance with a first condition; executing the maintenance process when the unit period number reaches a defined number; acquiring viscosity information related to viscosity of the liquid inside the liquid discharging head; and decreasing the unit period number when the viscosity information satisfies a second condition.
