  • Patent number: 10739069
    Abstract: A low-temperature drying apparatus includes a furnace body, an object holder, an infrared light transmitting plate, a supply device, a discharge device, and infrared heaters. The object holder holds an object to be dried so that the object to be dried is placed in the furnace body. The infrared light transmitting plate is arranged on a surface of the furnace body that faces the object holder. The cooling flow generating device generates a cooling flow in a space between the object to be dried that is held by the object holder and the infrared light transmitting plate.

  • Patent number: 9757952
    Abstract: Printing can continue while replacing ink cartridges. The printer 1 detects and reports an ink supply disabled state in which ink cannot be supplied from ink cartridges 9a to 9d. If a cover-open state, in which the cover 8a that opens and closes the cartridge holder 8 is open, is detected and the ink supply disabled state is also detected while printing is in progress, printing is permitted to continue using ink in buffer tanks (pressure control chambers 13a to 13d) while displaying a warning instead of going to an error state. Interruptions to printing due to a cover-open error while replacing ink cartridges 9a to 9d can therefore be avoided.
