A print device of the present invention can print a format sheet in which a user fills in some items which are necessary for a service man to promptly and properly process an inquiry from the user concerning a printed result. In such a print device, when an item name format information print key on an operation panel is operated, first item name format information data are read from a format information memory of a ROM and an item name format is printed on a first page of a printing paper. Next, second item name format information data are read from the format information memory of the ROM and the printer settings are read from a set condition memory stored in a RAM. The data of the second item name format information data and the settings are combined, the combined data are printed on the second page of the printing paper.

Print device capable of printing a format sheet in which items about a

A perfecting printer for performing a double-face printing operation of printing images on obverse and reverse faces of at least one sheet on the basis of a series of print data input from an external device and a method for controlling the double-face printing operation of the printer. The perfecting printer includes a page memory having an empty area for storing a series of print data for the obverse and reverse faces of the sheet input from external device, and a control unit for judging as to whether the empty area is no longer available in the page memory while the series of print data are being stored into the page memory and forcibly printing print data for the obverse face of the sheet on the sheet when it is judged that the empty area is no longer available in the page memory and that only the print data for the obverse face of the sheet are completely stored in the page memory.

Perfecting printer and method for controlling double-face printing

A perfecting printer for performing a double-face printing operation of printing images on obverse and reverse faces of at least one sheet on the basis of a series of print data inputted from an external device and a method for controlling the double-face printing operation of the printer. The perfecting printer includes a page memory for storing as page data at least both of the first and second print data in the series of the print data, and a control unit for printing the first and second print data on both of the obverse and reverse faces of the sheet when it is judged that the page data to be printed on the reverse face of the sheet exists in the memory and promptly printing only the first print data on the obverse face of the sheet when it is judged that the page data to be printed on the reverse face of the sheet does not exist in the memory.

A printer, which can adjust the attached position of the print hammer without a device specifically provided for the position-adjustment, is provided with an adjustment mode in addition to a normal printing mode. In the adjustment mode, a predetermined type on the type wheel is set into a predetermined printing position by the rotation of the type wheel, in the same manner as in the normal printing mode. Accordingly the attached position of the print hammer is adjusted easily to establish accurate contact between the hammer and the type in the printing position.

Printer adjusting the print hammer position for precise printing

A paper feeder for a printer in which a paper separator roller 15 is rotatably provided in the end portion of a paper holder 12 so that when a paper feed roller 14 is rotated in the paper feed direction, the paper separator roller 15 is arranged to stop at a predetermined position and act similarly to a conventional friction pad, while when the paper feed roller 14 is rotated in the paper return direction, the paper separator roller 15 also rotates in synchronization with the above rotation. By way of vibrating the paper separator roller 15 in the rotational direction or another direction, paper sheets P stacked on the paper holder 12 are vibrated for the purpose of being successively moved in the portion at which the two rollers 14 and 15 are positioned in contact with each other. As a result of this structure, the paper feeder of the printer according to the present invention can be prevented from local abrasion of the paper separator roller 15 causing papers to be fed in an overlap manner, and stop of paper feed can be prevented, and papers can be assuredly fed one at a time to the printing mechanism portion 1.

A carriage drive unit for a printer includes a typewheel and a printing hammer for striking a type element of the typewheel against a ribbon to reproduce the type element on a printing paper, both of which are provided on a carriage. The carriage is driven by a carriage drive motor in response to a drive control signal SG2 output by a CPU, before the printing hammer, which is driven by a hammer drive motor in response to a drive control signal SG5, reaches a printing position, for avoiding a loss time period due to a carriage response delay upon a start of the carriage drive motor.

Carriage drive unit for avoiding a loss time period in a printer

A carriage drive control device to enable printing on a printing sheet from the leading edge thereof. A carriage drive control device repositions a carriage supporting a print head and a paper guide member at the midpoint of a printing line prior to each advance of the printing sheet as long as the leading edge of the printing sheet has been advanced beyond the printing line by a distance less than a predetermined distance.

A paper check device for a printer including paper feed means, a light emitter, a light receiver, reflectance determination means, and paper check means. The paper check means determines that a paper is not on the platen when the platen is detected to be moving and a determined reflectance is in a preset range for a time interval longer than another preset value. The paper check device correctly detects whether the paper is on the platen even if the paper with already printed patterns of low reflectance is employed.
