Medium processing apparatus and image forming system incorporating same

A medium processing apparatus comprising:

• a liquid applier configured to apply a liquid on a sheet on which a given process is to be performed;
• a first liquid storage configured to store the liquid to be supplied to the liquid applier;
• a second liquid storage configured to store the liquid to be supplied to the first liquid storage;
• a liquid flow passage connecting the first liquid storage and the second liquid storage;
• a liquid leakage detector configured to detect leakage of the liquid from at least one of the first liquid storage or the second liquid storage;
• and
• a liquid flow limiter configured to limit a flow of the liquid from at least one of the first liquid storage or the second liquid storage in response to a detection of the leakage by the liquid leakage detector, wherein
• the medium processing apparatus further comprises,
• a first coupler configured to couple the first liquid storage and the liquid flow passage, and
• a second coupler configured to couple the second liquid storage and the liquid flow passage,
• the liquid leakage detector includes,
• a first leakage detector configured to detect leakage of the liquid from the first liquid storage, and
• a second leakage detector configured to detect leakage of the liquid from the second liquid storage, and
• the liquid flow limiter includes,
• a first flow limiter configured to close the first coupler in response to the detection of the leakage by the first leakage detector, and
• a second flow limiter configured to close the second coupler in response to the detection of the leakage by the second leakage detector.
