If the value exceeds the maximum limit, the toner is insufficient. In such a case, replenish the toner in the following SP modes (the amount will be sufficient by replenishing up to 6 times):

SP3-015-003: TnrSplyK

SP3-015-004: TnrSplyY

SP3-015-005: TnrSplyM

SP3-015-006: TnrSplyC

After replenishing the toner, be sure to execute SP3-017-001 (TnrRmnSnsFc) and SP3-017-002 (TnrRmnSnsBk). Otherwise, the report of the toner amount will not be updated.
