Common questions
What does the 1688 error mean on a Canon printer?
An ink tank is empty or reporting empty. The printer stops to avoid printing without ink. Replacing or, where supported, resetting the reported tank clears it.
Is the 1688 error serious?
Not usually. Codes at this level normally clear once the condition they describe is dealt with, and a printer that carries on working afterwards has nothing further wrong with it.
