  • Patent number: 11097535
    Abstract: A printing apparatus using a printhead that includes an inspection circuit for inspecting an ink discharge status for each nozzle performs an inspection processing. The apparatus selects a nozzle as a target of inspection of the ink discharge status, sets a threshold value for inspecting a detection result of a temperature detection element corresponding to the selected nozzle, and uses the inspection circuit and the set threshold value. The apparatus receives, from the printhead, an inspection result for the selected nozzle, determines, based on the received inspection result, a threshold value to be used by the inspection circuit for inspecting the discharge status of the selected nozzle in a subsequent inspection, and stores the determined threshold value in a memory.

  • Publication number: 20210122167
    Abstract: A print medium is conveyed in a first direction and a printing head prints an image on the print medium by using a printable region of the print head that extends in a second direction crossing the first direction. Storing units can feed multiple sorts of print media. Among the multiple sorts of the print media, the print medium to print a check pattern for checking a printing state of the printing head is selected as the print medium to be fed from the corresponding storing unit. The check pattern is printed on the print medium by using a portion of the printable region of the printing head corresponding to a size of the print medium fed from the storing unit.

  • Patent number: 10623314
    Abstract: A switch system allows free change of a grain degree of monitoring without being conscious of a routing control. For example, a control protocol of a transmitter is used based on the open flow (OpenFlow) technique to control the monitoring function of the switch system, and the centralized control of the monitoring can be realized as the whole network and the monitoring result is reflected on the routing control. Here, the switch has a flow table for packet transfer and a flow table for monitoring. Both of the tables are searched to one packet and a multi-hit operation is performed to execute the operation of each of the entries. That is, both the tables are searched and the packet is transferred according to corresponding flow entries.
