1688

Cause

The 1688 support code signifies that the printer has detected that one or more of your ink tanks is empty.

What to Do

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:

(a) For each ink tank identified by the printer as being empty, disable the function that detects the level of ink remaining by touching the Stop button on the printer for at least five (5) seconds and then releasing it. 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. Please note that image quality may be diminished if you PRINT or COPY when there is little ink remaining in the tank(s).

OR

(b) Open the scanning unit / cover, replace each ink tank identified by the printer as being empty, and close the printer’s cover. Canon recommends the use of new, genuine Canon ink tanks for optimal image quality.

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:

(a) For each ink tank identified by the printer as being empty, disable the function that detects the level of ink remaining by touching the Stop button on the printer for at least five (5) seconds and then releasing it. You will be able to SCAN (or FAX if your printer has that capability) as long as the empty ink tanks remain installed in the printer.

OR

(b) Open the scanning unit / cover, replace each ink tank identified by the printer as being empty, and close the scanning unit / cover. Canon recommends the use of new, genuine Canon ink tanks for optimal image quality.

Note

• If the function for detecting the remaining ink level is disabled, the ink tank in gray is displayed on the LCD when checking the current estimated ink level.
