Canon 1640 on an inkjet printer: ink at the tank's lower limit
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On PIXMA G3010 printers the ink in one tank may have reached the lower limit line. Look at the tanks and, if it is below that line, refill that colour before printing again.
Safety first
Stop and check this first
- Do not keep printing with ink below the lower line: Canon warns the printer may consume ink to recover and may be damaged.
- If you continue with the Black or Color button, the level warning stops working until you refill every colour to the upper line.
Safe checks you can perform
- Tank levels by eye
- Refill of the indicated colour
- Level warning reset

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.
Tank levels by eye
- Who:
- you.
- How:
- look at the ink in each tank and compare it with the lower and upper limit lines marked on it.
- Result that matters:
- you know which colour is below the lower line.
- If a colour is below:
- refill it.
- If all have enough ink:
- the warning may come from the estimate; go on to the reset.
- Evidence to keep:
- photo of the tanks with the lines visible.

Refill of the indicated colour
- Who:
- you.
- How:
- refill the tank with the matching colour following the manual's tank refilling procedure.
- Result that matters:
- level above the lower line.
- If the warning clears:
- you can keep printing.
- If it stays:
- check the colour and bottle match the manual.
- Evidence to keep:
- photo of the refilled tank and the bottle used.

Level warning reset
- Who:
- you.
- How:
- if you kept printing with the Black or Color button, refill every colour to the upper line and press the Black or Color button for at least 5 seconds to reactivate the warning, as Canon says.
- Result that matters:
- level warning active and accurate.
- If it reactivates:
- the printer warns you about levels again.
- If you do not fill every tank to the upper line:
- Canon warns the notification may be inaccurate.
- Evidence to keep:
- photo of the tanks filled to the upper line.

What it means
In the PIXMA G3010 manual, Canon says 1640 means the remaining ink in one of the tanks may have reached the lower limit line. It asks you to check visually and refill the corresponding colour. It warns that printing below that line may make the printer consume ink to return to printable status and may damage it. You can keep printing with the Black or Color button, but the ink level notification then stops working. The code is an estimated level warning, not a fault.
