Abstract | To provide means that can suppress air from intruding from a tank into a head even if a liquid level sensor fails.SOLUTION: The liquid discharge device reads out identification information from a memory of an IC substrate 247 in response to attachment of a cartridge 200 thereto, reads out ink quantities Vc and ink quantities Vs corresponding to the identification information from an EEPROM 134 and calculates a threshold Non the basis of the read-out ink quantities Vc and Vs. Further, the device renews count values TN by values corresponding to the quantities of ink instructed to be discharged from a head 21 under a recording instruction and makes a display 17 to display an S_Empty notification screen, in response to the fact that the renewed count values TN reach the calculated threshold N.SELECTED DRAWING: Figure 9
【課題】液面センサが故障したとしても、タンクからヘッドへ空気が進入することを抑制する手段を提供する。【解決手段】装置は、カートリッジ200が装着されたことに応じて、IC基板247のメモリから識別情報を読み出し、EEPROM134から識別情報に対応するインク量Vcと、インク量Vsとを読み出し、読み出したインク量Vc,Vsに基づいて閾値Nth2を算出する。また、当該装置は、記録指示でヘッド21からの排出が指示されたインクの量に相当する値でカウント値TNを更新し、更新したカウント値TNが算出した閾値Nth2に到達したことに応じて、S_Empty報知画面をディスプレイ17に表示させる。【選択図】図9 |
