To avoid problems caused by the worn-out of the developer roller surface and deterioration of
the toner ceiling, “Replace Toner” message is displayed and the print operation is prohibited
when the number of the rotations of the developer roller reaches the upper limit even if toner
remains. The upper limit of the number of the rotations of the developer roller is shown in the
table below. Due to the specification change of detecting standard of “Replace Toner”, the
upper limit differs depending on the version of main firmware.
(1) Main Ver. from Master to Ver. 1.15
(2) Main Ver.1.17 or later
