Title: Printer
Inventor: KONO TETSUSHI
IPC: B41J29/13
Filed: 2000-02-24
Abstract: PROBLEM TO BE SOLVED: To obtain an ink jet printer comprising a primary power supply throw-in means for bringing about a state where power is supplied physically to the printer, and a secondary power supply throw-in means for subsequently bringing about a state where the printer function can be executed in which increase of ink consumption due to operation for recovering ink from a head through suction is suppressed appropriately. SOLUTION: The number of times when a secondary power supply is turned on is counted (405A) and the count is stored in a nonvolatile memory 407. A decision is then made whether the count is equal to or higher than a specified value or not when the secondary power supply is turned on, and only when the count is equal to or higher than the specified value, suction recovery operation is performed, the count and the content of the nonvolatile memory are cleared and counting operation is disabled until a hard power supply is turned off. Since the count is stored even if a primary power supply is turned off, necessity of recovery operation can be determined when the secondary power supply is turned on based on the execution state of recovery operation of the head before the primary power supply is turned off.
