Abstract
A method of detecting an ink residual quantity in an ink jet printer, which is capable of eliminating a possibility of blank printing even when effecting a print on the large-sized paper by detecting the ink residual quantity at a high frequency and of keeping a good printing efficiency. The ink residual quantity is detected in an equispeed motion area of the carriage. The ink residual quantity can be stably detected per line without stopping the carriage and providing a special liquid level oscillation preventive mechanism.
