Quick answer

1684 means an ink tank cannot be recognized. Match the exact TS8300-series model, stop the job and follow Canon's documented branch once.

Safety first

Safe checks you can perform

  • Preserve the exact failure branch
  • Verify the correct ink tank

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Measured Canon service handoff for 1684

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Measured Canon service handoff for 1684

    What they doProvide the exact model, serial number, 1684 message, job stage and the result of “Verify the correct ink tank”. Ask the technician to reproduce the branch “an ink tank cannot be recognized” against the exact service information and record the failed observation or measurement before quoting a part.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Preserve the exact failure branch

    No special tools

    Photograph 1684, the full touch-screen message and the exact TS8300 model. Note the paper source, active job and whether the code appeared before movement, during feed or after printing. The code narrows the branch to “an ink tank cannot be recognized”; it does not identify a replacement part.

  2. Verify the correct ink tank

    No special tools

    Stop the job, identify the indicated tank and compare its exact Canon designation with the printer/model region. Install the appropriate tank fully without touching contacts. If the correct tank is still not recognized, stop and contact support.

What it means

Canon's official TS8300-series manual says support code 1684 means an ink tank cannot be recognized. This applies to the documented TS8320, TS8340, TS8350/51/52, TS8360, TS8370 and TS8390/91/92 family, not every Canon printer.

    The tank may be unseated or incompatible with this exact regional TS8300 model.

  • 1684 persists after the documented actionPossible

    If 1684 returns once the visible condition has been corrected, the safe external branch is exhausted. The recurrence proves only that the documented action did not resolve this branch; the display alone cannot select or confirm an internal component.
