What to do if my Ricoh All in One Printer says 'SC978 Left ink collection tank'?
- JJanet HancockSep 12, 2025
If your Ricoh All in One Printer displays the error 'SC978 Left ink collection tank', it means the ink collection tank sensor has detected a full condition. You can try cycling the printer off and on to see if that resolves the issue. If not, print the System Summary by pushing [Menu], selecting "List/Test Print" then push [#Enter] and check the Total Counter reading. If necessary, replace the left ink collection tank.
