  • 20001Dispenser

    Timeout while feeding notes from the cassette during a dispense.

    What to do: Open the dispenser, clear any jammed notes and clean the feed sensors. Persistent timeouts usually point to a worn feed roller or dispenser module.

    Shop dispensers & cassettes
  • 20002Dispenser

    A note that is too long was detected during dispensing (double note or jam).

    What to do: Remove any stuck or joined notes, fan and re-load the cash, and check the note-thickness sensor. Recurring errors indicate a dispenser that needs service or replacement.

    Shop dispensers & cassettes
  • 20003Dispenser

    The gap between notes was too short during a dispense (feed error).

    What to do: Straighten and re-load the cash, remove damaged bills, and clean the transport path. If it repeats, the dispenser feed mechanism likely needs attention.

    Shop dispensers & cassettes
  • 20004Dispenser

    A skewed or slanted note was detected in the transport path.

    What to do: Reseat the cassette, remove worn or curled notes, and inspect the transport sensors. Frequent skew errors are common on worn refurbished dispensers.

    Shop dispensers & cassettes
  • 20005Dispenser

    Notes were rejected to the reject bin during the last transaction.

    What to do: Clear the reject bin, inspect the rejected notes for damage, and re-load with clean, flat bills. Chronic rejects usually mean the dispenser needs recalibration or replacement.

    Shop dispensers & cassettes
  • 20015Dispenser

    Note jam detected at the dispenser exit / shutter.

    What to do: Power down, open the dispenser, clear the jam at the exit and check the shutter operation. Test with a small dispense before returning the ATM to service.

    Shop dispensers & cassettes
  • 200A0Dispenser

    The cash cassette is not detected or has been removed.

    What to do: Reseat the cassette firmly until it locks, and check the cassette detect switch and connector. A damaged cassette should be replaced.

    Shop dispensers & cassettes
  • 200A1Dispenser

    The reject bin is not detected or is not seated correctly.

    What to do: Reseat the reject bin and confirm the detect switch engages. Inspect the connector if the error persists after reseating.

    Shop dispensers & cassettes
  • 2003DDispenser

    Communication error between the mainboard and the dispenser (CDU).

    What to do: Power the ATM off and on to re-establish communication, then check the dispenser data cable. A failing dispenser controller may need replacement.

    Shop dispensers & cassettes
  • 4100CDispenser

    Low cash — the cassette is at or near empty.

    What to do: Refill the cassette and reset the bill count in Operator Function. This is informational, not a hardware fault.

  • 30001Card Reader

    Communication error with the card reader.

    What to do: Power cycle the ATM and check the card reader data cable. A card reader that repeatedly loses communication should be replaced.

    Shop card readers
  • 30020Card Reader

    Card jam or read error in the card reader.

    What to do: Clear any stuck card, run a cleaning card through the reader, and test with a known-good card. Persistent read errors indicate a worn read head.

    Shop card readers
  • 30030Card Reader

    IC (chip / EMV) read error.

    What to do: Clean the chip contacts with a cleaning card and test another chip card. If chip reads keep failing, the EMV card reader likely needs replacement.

    Shop card readers
  • 40001Receipt Printer

    Communication error with the receipt printer.

    What to do: Power cycle the ATM and check the printer data and power cables. A printer that stays offline should be serviced or replaced.

    Shop receipt printers
  • 40004Receipt Printer

    Receipt paper is out or the paper-near-end sensor is triggered.

    What to do: Load a fresh roll of thermal receipt paper, making sure it feeds shiny-side up, then clear the error in Operator Function.

    Shop receipt printers
  • 40007Receipt Printer

    Receipt paper jam.

    What to do: Open the printer, remove the jammed paper and any torn pieces, and reload the roll cleanly. Clean the cutter area if jams recur.

    Shop receipt printers
  • 4000AReceipt Printer

    Printer cutter error.

    What to do: Clear any paper caught in the cutter and cycle power. A cutter that will not home usually means the print head/cutter assembly needs replacement.

    Shop receipt printers
  • 4001CCommunication

    TCP/IP communication error reaching the processor / host.

    What to do: Check the internet connection, router and network cable, and confirm the host and port settings in the ATM. Reboot the modem/router if needed.

    Shop ATM parts
  • 3D000Communication

    No dial tone / modem connection error (dial-up units).

    What to do: Confirm the phone line is live and connected, or switch the ATM to a TCP/IP connection for reliability.

    Shop ATM parts
  • 10003Communication

    Timeout waiting for a response from the processor during a transaction.

  • 61000Keypad / EPP

    The encrypting PIN pad (EPP) is not detected.

    What to do: Power cycle the ATM and check the keypad connector. An EPP that is not recognized will need to be re-injected with keys or replaced.

    Shop keypads (EPP)
  • 61003Keypad / EPP

    EPP tamper or master/MAC key error.

    What to do: The keypad has flagged a tamper or lost its keys and must have its master and communication keys re-loaded by your processor, or be replaced.

    Shop keypads (EPP)
  • 00000System

    No error — normal operation.

    What to do: No action required. The ATM is reporting a healthy status.

  • 50001System

    General SP (dispenser controller) reset / initialization error.

    What to do: Power the ATM off for 30 seconds and back on to reinitialize. If the ATM will not clear the error, the dispenser or mainboard may need service.
