1640
Cause
The 1640 support code signifies that the remaining ink level in one of the ink tanks may have reached the lower limit line shown on the ink tank.
What to Do
To check the remaining ink level, visually inspect the remaining ink in the ink tank.
How to resolve the error depends on the function being used.
1. To PRINT or COPY
If you intend to PRINT or COPY, you should take one of the following steps by following the printer's instruction:
- Disable the function for notifying you of the remaining ink level. If, due to individual usage factors, there is some residual amount of ink in the tank(s), you will be able to PRINT or COPY until the remaining ink is depleted.
However, if printing or copying is continued when the remaining ink level is below the lower limit line, the printer may become impossible to print even after refill with ink. In this case, please note that the printer may consume excess ink to return to printable status.
The function for notifying you of the remaining ink level is designed to work properly on the assumption that the ink tanks are refilled to upper limit line. If you want this function to restore properly, refill the ink tank(s) up to the upper limit line shown on the ink tank(s) and enable the function again.
Refer to Ink level monitor for instructions on enabling the function for notifying the remaining ink level.
OR
- Refill the ink tank with the corresponding color of ink.
2. To SCAN or FAX
If you choose not to disable the function that detects the level of ink remaining or refill the ink tank, scan (or fax if your printer has that capability) from an external device such as a computer, smartphone, or tablet using the corresponding application software.
