The continued use of any physically empty cartridge can result in the printhead of the cartridge burning out. From here the ink level will still read as being low, but you can continue printing with this cartridge until the ink physically runs out and the quality of the prints deteriorates as a result. Holding down this button for five seconds indicates to your printer that you are aware of this low/empty cartridge estimate but would like to continue printing regardless. It may be grey, pink or even red in appearance depending upon the model of your printer. Whilst the name with which the button is referred to may change, the symbol it is represented with will always remain the same.Īs shown above the symbol that represents the RESUME button is an upside-down triangle in a circle. Simply hold down your printers STOP/RESET/RESUME button for five seconds and then release. This series of Canon printers allows you to continue printing with a single button press and will usually give this prompt in a fairly sizable message once it detects that the cartridge may be empty. Indeed you can and it is exceptionally easy. As a result of this way of estimating ink levels, even an original Canon ink cartridge will almost certainly have some ink left when your printer warns you it is empty. From this information your printer estimates the ink level of the cartridge and when it believes the ink cartridge is running low/empty will present you with the “Check Ink” 1686 or 1688 message.


Instead the cartridge just monitors how many pages have been printed and the average page coverage since it was first installed into a printer. This is due to the fact that these Canon printers have no way of looking inside the cartridge or detecting fresh ink.

If you have just installed a new remanufactured cartridge or have just refilled your own cartridge, you may be surprised to see this error message so quickly. There is however a way you can carry on printing as we will discuss below… Whatever error you are receiving your printer will stop when it believes the cartridge is empty and refuse to print without intervention from you. Canons official text used to describe the error states “The ink may have run out” (Check Ink 1686) and “The ink has run out” (Check Ink 1688). The Canon “Check Ink 1686” and “Check Ink 1688” are low ink warnings used by an entire series of inkjet printers that take the PG-540, PG-540XL, CL-541 and CL-541XL ink cartridges.
