Even if I replace it with new ink, "Used ink" is displayed.

 When replacing a new ink cartridge, "used ink" may be displayed because of the printer.
Ricoh printers have a sub-tank to hold ink.I'm refilling the sub tank with ink from the ink cartridge.
If ink is not supplied to the sub tank when new ink is set, the printer determines that there is no ink.
It may be displayed as "Used ink".
The genuine manufacturer has disclosed the firmware to solve the problem.
However, please note that only the model number "SG5100" is available.

The firmware update page can be accessed from the URL below.
