Description

Recording apparatus Technical Field The present disclosure relates generally to a recording apparatus. Background Some known recording apparatuses that perform recording by discharging ink from a recording head to a medium include a reserved portion in which ink to be supplied to the recording head is reserved and/or a maintenance unit that performs maintenance on the recording head. In the case of leakage of ink from the inside of such a device, measures need to be taken to prevent ink from leaking out of the device. Japanese patent application laid-open No. 2007-160125 discusses a configuration in which an ink absorber is disposed at a portion where ink leakage may occur inside the apparatus and an ink detection unit that detects the absorption of ink by the ink absorber is provided. In the configuration discussed in japanese patent application laid-open No. 2007-160125, ink leakage inside the apparatus is detected by detecting ink absorbed by the ink absorber. Therefore, after the occurrence of the ink leakage, it should take time to detect the ink leakage. The present disclosure aims to reduce the time from the occurrence of ink leakage to the detection of ink leakage in the case where ink leakage occurs inside a recording apparatus.
