International Classification:

B41J029/38
B41J002/01

US Classification:

347 16, 347101

Abstract:

A print medium is printed on with a printhead of an ink jet printer. The print medium is advanced in an advance direction a predetermined amount. The print medium is printed on with the printhead in an area corresponding to the predetermined amount. A determination is made of an end of printable area on the print medium in the advance direction. The print medium is advanced in the advance direction a minimum reliable move amount, dependent upon the end of printable area determination. The minimum reliable move amount is less than the predetermined amount. The print medium is printed on with the printhead in an area corresponding to the minimum reliable move amount.

Abstract:

A method of printing on a print medium includes using a first quantity of nozzles of a printhead to print a first set of scan lines of a plurality of scan lines at an edge of the print medium; using a second quantity of nozzles of the printhead to print a second set of scan lines of the plurality of scan lines in an interior region of the print medium; using a third quantity of nozzles to print a third set of scan lines of the plurality of scan lines to transition between the edge and the interior region, the third quantity of nozzles being greater in number than the first quantity of nozzles and less in number than the second quantity of nozzles; and printing each scan line of the plurality of scan lines forming the image with a same number of multiple passes of the printhead, regardless of the number of nozzles used for printing during a particular pass of the printhead.

B41J002/15

US Classification:

347/041000

Abstract:

A first method obtains a printer having a single-printhead horizontal resolution of H dpi. Dots are printed using first and second printheads in the same print pass. The first printhead is enabled and the second printhead is non-enabled during a first portion of a carrier-movement distance equal to 1/H, and the second printhead is enabled and the first printhead is non-enabled during a second non-overlapping portion of such distance. A printer and a printhead driver for performing the first method are described. A second method obtains a printer having a single-printhead resolution of H horizontal dpi by V vertical dpi. First print data for the first printhead and second print data for the second printhead of H/2 horizontal dpi by V vertical dpi are obtained, are horizontally interlaced creating H horizontal dpi by V vertical dpi, and are printed using the first and second printheads in the same print pass.

International Classification:

G06K 15/10

US Classification:

358 18, 358 12

Abstract:

A method of printing a high resolution image with a printhead in a multi-pass printing mode includes subdividing the high resolution image into a plurality of low resolution sub-images; subdividing each low resolution sub-image into a plurality of low resolution swath portions; and allocating an amount of a memory for buffer storage, the amount being only sufficient to store data corresponding to less than two of the low resolution swath portions. The method also includes, for each low resolution swath portion: halftoning each low resolution swath portion to generate a corresponding halftoned low resolution swath portion, the halftoning of each low resolution swath portion of a particular low resolution sub-image being performed independently of halftoning the low resolution swath portions of other low resolution sub-images; storing the halftoned low resolution swath portion into the amount of the memory; and printing the halftoned low resolution swath portion.

International Classification:

B01L 3/00
G01N 35/10

Abstract:

A pipette-fillable fluid reservoir body. The fluid reservoir body includes two or more discrete fluid chambers therein. At least one of the fluid chambers contains a pressure compensation device and at least another one of the fluid chambers is devoid of a pressure compensation device. Each of the fluid chambers is in fluid flow communication with a fluid supply via, and each of the fluid chambers have sidewalls and a bottom wall attached to the side walls, wherein the bottom wall slopes toward the fluid supply via. The fluid reservoir body also includes an ejection head support face in fluid flow communication with the fluid chambers for attachment of a fluid ejection device to the ejection head support face for ejecting fluid from the fluid chambers.

Assignee:

FUNAI ELECTRIC CO., LTD - Osaka

International Classification:

G06F 3/12

Abstract:

A system tracks the exact amount of ink remaining in printhead cartridges used in printers connected to a network. Each printer stores a history of cartridges that have been used in the printer. Each cartridge stores a status indicator that indicates whether the cartridge has been used before in any printer. When a printer receives a previously-used cartridge, the printer broadcasts a request for information about that cartridge from the other printers. Each printer having the matching printhead identification number in its history reports over the network the last recorded ink dot count associated with the matching printhead identification number. The requesting printer chooses the most up-to-date response based on the highest dot count or the latest time-stamp. The requesting printer then updates its memory using the dot count from the most up-to-date response and begins counting dots from that updated count for subsequent print jobs performed using the installed cartridge.

International Classification:

G05B 19/042
H04W 4/00
H04W 84/12

Abstract:

A controller for controlling a microfluidic device. A first computing device receives commands from a user interface in a relatively high level protocol using a standardized command language, converts the commands from the standardized command language into a relatively mid-level protocol, sends the commands in the relatively mid-level protocol, receiving data, converts the data into the standardized command language, and sends the data to the user interface according to the standardized command language. A second computing device receives the commands from the first computing device in the relatively mid-level protocol, converts the commands from the relatively mid-level protocol to at least one relatively lower level protocol that is understood by a microfluidic device that is connected to the controller, receives data from the microfluidic device, and sends the data to the first computing device.

International Classification:

B41J 29/393
B41J 2/21

Abstract:

A method for reducing printing defects in inkjet printing includes determining a respective colorant density for each colorant of a plurality of colorants for a region to be printed; determining a colorant dry-time signal strength as a function of a combined colorant density value based on the respective colorant densities of the plurality of colorants for the region to be printed; determining a respective colorant swath contraction strength for each colorant as a function of the respective colorant density; selecting a dry-time threshold which if met by the colorant dry-time signal strength indicates that a dry-time defect may occur; selecting a respective colorant density threshold for each colorant which if met by the respective colorant density indicates a visible swath contraction may occur; and determining a printing action to be taken based on whether the dry-time threshold is met and whether at least one respective colorant density threshold is met.
