摘要： A fluid droplet discharge device executes a head cleaning process to quickly remove bubbles that have entered the fluid supply path when it is likely that bubbles have entered in a flushing process. If the ink cartridge cover 2b is opened during flushing and it is possible that bubbles have entered the ink supply path, ΔN1 is added to the count Na of the cleaning intensity setting counter N. If the count Na exceeds a threshold value Nmax in a head cleaning operation performed when a defective nozzle is detected, cleaning (CL4) with the highest cleaning intensity level is applied. Because ΔN1 is added to the count Na if the ink cartridge cover 2b is opened when flushing, the timing when this cleaning operation (CL4) is applied is accelerated. Bubbles that have entered the fluid supply path can therefore be removed sooner.

摘要： A method of inspecting a discharge state of a nozzle prevents wrongly determining that discharge is normal even though fluid droplets are not discharged normally. In a fluid droplet discharge device such as an inkjet printer, a momentary induced current is produced when a charged ink droplet 17c lands on a head cap 31 with a potential difference. A voltage change detection unit 39 detects the induced current as a voltage change. A decision unit 40 determines that the ink discharge state is normal if the maximum amplitude L of the voltage change detected by the voltage change detection unit 39 in a first period S is greater than or equal to a first threshold value Q. If the amplitude of voltage change detected in a third period U after the specific period has passed goes to a second threshold value R, a decision cancellation unit 41 determines that noise is contained in the voltage change. If the ink discharge state is determined to be normal and noise is determined to be contained in the voltage change, inspection is repeated and the normal discharge decision is cancelled.
摘要翻译：检查喷嘴的排出状态的方法防止了错误地确定排出是正常的，即使流体液滴不能正常排出。在诸如喷墨打印机的流体液滴喷射装置中，当带电墨滴17c以电位差落在头盖31上时，产生瞬时感应电流。电压变化检测单元39将感应电流检测为电压变化。如果在第一周期S中由电压变化检测单元39检测到的电压变化的最大振幅L大于或等于第一阈值Q，则判定单元40确定墨水排出状态是正常的。如果振幅在特定时段过去之后的第三时段U中检测到的电压变化变为第二阈值R，判定消除单元41确定电压变化中包含噪声。如果墨水排出状态被确定为正常并且确定噪声被包含在电压变化中，则重复检查并消除正常放电判定。

摘要： A cleaning control method accurately detects the nozzle recovery condition after cleaning and efficiently eliminates ejection problems. When a regular cleaning command is received from a host device 31, the inkjet printer 1 applies an ink suction operation to the inkjet head 13 as a first cleaning step. After the ink suction operation ends, a nozzle check is performed after waiting a delay time T. If a faulty nozzle is detected, a second ink suction operation is performed, the delay time T is waited, and the nozzle check is then run again. The ink suction operation, waiting delay time T, and nozzle check repeat during regular cleaning until the number of faulty nozzles is less than or equal to a reference number, or the nozzle check has been performed a maximum number of times. Each delay time T is set according to the suction strength in the ink suction operation.

摘要： An inkjet printer and a head cleaning method for an inkjet printer reduce the time required for head cleaning while also reducing needless ink consumption. The control unit 30 of the printer 1 confirms if a timer AID flag, impact detection flag, startup process flag, AID hold flag, or cover closed flag is set before executing the cleaning process a first time. If any one of the flags is set, the possibility that there are numerous defective nozzles in the printer 1 is high, and a stronger or more intense cleaning process (CL1 or CL2) is executed. Whether cleaning process CL1 or CL2 executes is determined according to the number of defective nozzles detected in the first nozzle check. If no flag is set, the weakest cleaning process (CL0) is executed.

摘要： An inkjet printer can desirably clean two inkjet heads mounted on a head carriage before printing starts. The inkjet printer 1 has first and second inkjet heads 13A and 13B mounted on a head carriage 14. Before printing starts, the inkjet printer moves the head carriage 14 from a home position HP to a shift position SP so that the second inkjet head 13B, which is closest to the home position HP, is opposite a maintenance head cap 22 with an ink absorption capability and cleans the inkjet head. The head carriage 14 is then returned to the home position HP so that the first inkjet head 13A is opposite the maintenance head cap 22 and cleans the inkjet head. The head carriage 14 then moves to the printing area C side and printing starts.
