1640

Cause

The 1640 support code signifies that the printer has detected that the remaining ink in one or more 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. The action you should take to resume operating the printer depends upon which function(s) of the printer you intend to use.

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:

(a) Disable the function for notifying you of the remaining ink level. If 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, although image quality may diminish as the remaining ink in the tank(s) becomes depleted.

Please note that if you continue to PRINT or COPY when the remaining ink is below the lower limit line, the printer may consume excess ink as it attempts to return to normal image quality after it is refilled with ink.

To restore that function for notifying you of the remaining ink level, refill the ink tank(s) up to the upper limit line shown on the ink tank(s).

OR

(b) Refill the ink tank with the corresponding color of ink up to the upper limit line shown on the ink tank.

2. To SCAN or FAX

If you intend to SCAN (or FAX if your printer has that capability), you should take one of the following steps by following the printer’s instruction:

(a) Disable the function for notifying you of the remaining ink level. You will then be able to SCAN (or FAX if your printer has that capability). To restore that function, refill the ink tank(s) up to the upper limit line shown on the ink tank(s).

OR

(b) Refill the ink tank with the corresponding color of ink up to the upper limit line shown on the ink tank.
