What to Do
The 1686 support code signifies that the printer has detected an issue with one or more of your
ink cartridges.
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 cartridge identified by the printer as having an issue, disable the function that detects the
level of ink remaining by pressing the Stop button on the printer for at least five (5) seconds and then
releasing it. If there is ink in the cartridge(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 cartridge(s).
OR
(b) Open the printer’s cover, replace each ink cartridge identified by the printer as having an issue, and
close the printer’s cover. Canon recommends the use of new, genuine Canon ink cartridges 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 cartridge identified by the printer as having an issue, disable the function that detects the
level of ink remaining by pressing 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 all of the ink
cartridges remain installed in the printer.
OR
(b) Open the printer’s cover, replace each ink cartridge identified by the printer as having an issue, and
close the printer’s cover. Canon recommends the use of new, genuine Canon ink cartridges for optimal
