Canon Pixma TS8700 Series, Online Manual, Page: 554 / 589

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 level of ink remaining in an ink tank is disabled, the ink tank will
be displayed in white on the touch screen (if the printer has a touch screen) when you check the
estimated remaining ink level.
