Abstract: A line printer is provided in which disturbances during the start of printing are prevented with low power consumption. The printer has a motor control section which performs a stop printing operation by driving a stepping motor in a direction reverse to that in which print paper is fed by a predetermined number of steps and then turns off the stepping motor to stop printing and performs a start printing operation in which the stepping motor is driven in a forward direction by the same predetermined number of steps before starting a printing operation.

Abstract: While a transfer sheet 3 including a water-soluble base sheet on which a print layer is provided is floated on water, an adhesion is applied after the base sheet is dissolved, thereby to form a semi-fluidal print layer. An object is pressed against the print layer to achieve printing. In this technique, the present printing method and apparatus shorten the warm-up time required for dissolving the base sheet of the transfer sheet 3 to improve the working efficiency, and the transfer sheet 3 is previously cut at a predetermined length and is then floated on the water surface 5, so that wasteful consumption of the transfer sheet is reduced. The bottom of a water tank 11 is formed to be shallow in the left side than in the right side, so that the amount of water contained in the water tank 11 is reduced to shorten the warm-up time.

Abstract: The bearing lubrication system for a cylinder in a printing machine pumps oil from the driving gear side to the roller bearing. The gear side has a gear box and an oil sump with a supply of lubricating oil. An oil loop connects the bearing housing with the gear box fluidically via dry quick disconnects. The dry disconnects allow quick removal of the printing machine cylinder for maintenance or for print job retrofitting. As the printing machine cylinder rotates (it is driven from the gear box), oil is pumped from the gear box into the bearing housing. The bearing is thus lubricated and cooled. The oil is discharged from the bearing housing and returned to the gear box sump.

Abstract: A printer for printing on both sides of a document, such as a check being printed at a point of sale terminal, uses a single printing station to print on both sides of the document. The document is moved along a document path and past the printing station, with the first side of the document being printed, with an end portion of the document then being positioned to extend through a slot within a rotor. The rotor is then turned through a 180-degree angle in a first direction, with an end portion of the document being held within the rotor and wrapped around a segment of the rotor. This end portion is next driven back to the printing station for the second side of the end portion to be printed upon. Then the end portion is driven away from the printing station, as the other end of the document is pulled through the rotor. Finally, the rotor is returned by rotation through 180-degrees opposite the first direction.

Abstract: The present invention is embodied in a low-profile and narrow-width printer that has two rollers, a pick roller and a feed roller, and two roller motors. Each one of the two roller motors is used to drive one of the two rollers. As a result, a short gear train can be used to allow a longer paper path for enabling a low height printer. Also, a print media can be picked up from the input tray while another print media is being printed upon by an ink jet printhead or printhead. Thus, throughput of the printer can be enhanced when the printer is printing a multi-page document. Further, the printer straightens out print media that are skewed when picked up by the pick roller. Finally, the printer is able to locate a paper jam by using two sensors, one by the pick roller and the other by the feed roller.
