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.
Inspection by a Canon service centre
What they doIf 1366 does not clear with the lever at its right stop and the cover closed, an authorised Canon service centre checks the valve and the ink system.
They must show youthe valve lever working and a test print after the inspection.
In writingthe diagnosis, any parts replaced and the repair number.
Prepare the repair shipment as Canon describes
What they doIf the printer has to be sent away, Canon support confirms the transport procedure: valve closed, print head holder secured and the printer packed in a plastic bag and a sturdy box.
They must show youthe transport instructions that apply to your model.
In writingthe case number and who handles shipping and packing.
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.
Open the ink valve
- Who:
- you.
- How:
- open the scanning unit or cover, find the ink valve lever next to the tanks (part G in the manual's inside view) and tilt it firmly all the way to the right; then close the cover.
- Result that matters:
- the error clearing when the cover is closed.
- If 1366 disappears:
- the valve was simply closed.
- If it keeps appearing:
- think back to whether you ran a print head check.
- Evidence to keep:
- photo of the lever in its final position before closing.

Go over the end of the print head check
- Who:
- you, if you have just removed and refitted the print heads.
- How:
- check that the L and R heads sit in their holders, that the locking cover clicked and that both joint buttons are pushed in; then tilt the valve lever to the right and lower the cover gently.
- Result that matters:
- properly finishing a procedure that closes the valve halfway through.
- If with everything seated and the valve open the warning goes:
- a step was pending.
- If the warning persists:
- contact the Canon service centre.
- Evidence to keep:
- note of the steps repeated and the state of the Alarm lamp.

Review how the printer was moved
- Who:
- you, if the printer has just been moved house or shipped.
- How:
- confirm that the tank caps are closed securely, that the printer travelled and stands on its base without being tilted, and that you reopened the valve after setting it up; Canon closes the valve before packing to prevent leaks.
- Result that matters:
- understanding why the valve was closed and avoiding the warning next time you move it.
- If it matches a recent move:
- once the valve is reopened you can print.
- If there was no move and no head check:
- ask Canon before forcing anything.
- Evidence to keep:
- date of the move and a photo of the closed tank caps.

What it means
On the PIXMA G600 series (refillable ink tanks), Canon assigns support code 1366 to a closed ink valve. The valve lever sits inside the printer next to the tanks, and the manual says to operate it when transporting the printer: tilted left it closes, tilted right it opens. The official step is to open the cover, push the lever firmly to the right and close the cover. A 1366 does not prove that any part is broken; usually the lever was simply left closed after a move.

Symptoms and causes
Probable causes · in order
- Valve closed after moving the printerCommon
To move the printer or ship it for repair, Canon asks you to tilt the lever left and close the valve; if it is not reopened afterwards, 1366 appears.

- Valve not reopened after a head checkPossible
The print head installation check closes the valve at the start and opens it again at the end; skipping that last step leaves it closed.

- Lever not pushed fully to the rightPossible
Canon stresses tilting the valve lever tightly to the right; a lever left halfway can still count as a closed valve.
