A card reader maintenance system includes a card reader and a maintenance apparatus. The card reader includes a card convey path for conveying an inserted card, a drive circuit for driving the card convey path, a recording/reproducing head, arranged on the card convey path, for recording/reproducing data on/from the card, a card processing circuit for sequentially executing, in accordance with a predetermined procedure, a plurality of card processes including a card convey process for controlling the drive circuit to convey-the card to a position of the recording/reproducing head, a data reproducing process for causing the recording/reproducing head to reproduce data recorded on the card, and a data recording process for causing the recording/reproducing head to record data on the card, an error detection circuit for detecting an error in each card process while the card processing circuit executes the plurality of card processes, and an EEPROM for storing, on the basis of a detection output from the error detection circuit, error information indicating a card process in which an error has occurred. The maintenance apparatus includes a display unit for displaying the error information read out from the EEPROM during maintenance.
