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： A control method for a fluid ejection device and a fluid ejection device reliably eliminate dropped dots while reducing consumption of ink droplets ejected from the nozzles. A fluid ejection device that performs at least one of a cleaning operation that suctions fluid from the nozzles and a wiping operation that wipes the nozzle surface when dropped dots occur determines if an elimination history of removing dropped dots by the wiping operation is stored when dropped dots are detected as a result of testing for dropped dots and determining if dropped dots occur. When a history of eliminating dropped dots by means of a wiping operation is not stored, the fluid ejection device performs the wiping operation. When a history of eliminating dropped dots by means of a wiping operation remains in memory, the cleaning operation is performed without the wiping operation.

摘要： An inkjet printer can appropriately flush two inkjet heads disposed to a carriage. The inkjet printer 1 flushes the first inkjet head 13A before printing starts when print data is received (step ST1), and flushes a second inkjet head 13B while the carriage 14 returns from the printing area C to the home position A after printing ends (steps ST2, ST3). As a result, because the carriage 14 is not moved from the home position A before printing starts, the start of printing is not delayed. Furthermore, because the direction of carriage 14 movement does not change after the second inkjet head 13B is flushed, the carriage 14 returns to the home position A quickly. Starting printing the next print data is therefore not delayed.
