1688

Cause

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

Action

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 being empty, 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, due to individual usage factors, there is some residual amount of 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 scanning unit / cover, replace each ink cartridge identified by the printer as being empty, and close the scanning unit / 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 being empty, 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 the empty ink cartridges remain installed in the printer.

OR

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

Note

  • If the function for detecting the remaining ink level is disabled, is displayed on the LCD.

  • Since the information contained in the fax may be lost if it is printed in this condition, the received fax will not be printed and will be stored in the machine's memory until the ink cartridge is replaced. You must manually print out faxes that were stored in the memory. You can change the setting so that the received fax is forcibly printed out instead of being stored in the memory, but all or part of the fax information may not be printed because of the ink out condition.
