Toshiba e-Studio 2051c

When the counter value exceeds the setting value, the equipment notifies you of when the maintenance time has come by displaying the message “Time for periodic maintenance ****” on the control panel LCD. “****” in the message is a 4-digit hexadecimal number code. This number is allocated in the following manner, therefore the parts needing maintenance can be identified.

PM parts of the process unit (K) : 0008
PM parts of the process unit (Y) : 0001
PM parts of the process unit (M) : 0002
PM parts of the process unit (C) : 0004
Developer material (K) : 0080
Developer material (Y) : 0010
Developer material (M) : 0020
Developer material (C) : 0040
Parts other than the PM parts of the process unit : 0100

If multiple parts have reached the maintenance time, the sum of the corresponding code values listed above is displayed in hexadecimal numbers. For example, if the PM parts of the process units (K) and (C) and the developer materials (K) and (C) reach the maintenance time, the 4-digit hexadecimal number code will be “00CC” in hexadecimal numbers: 0008+0004+0080+0040=00CC.
