Toshiba e-Studio 4508AG

The maintenance times of the PM parts vary depending on the state of the parts, for example, if one part is replaced due to a problem during the operation, the maintenance time of another part will change accordingly. In this equipment, the optimal maintenance time corresponding to each part is displayed on the control panel LCD.

The [process unit (K)] explained below is a photoconductive drum or a cleaner unit which includes a photoconductive drum. The [developer material (K)] explained below is a developer material or a developer unit which includes a developer material. The [PM part other than the process unit] explained below is a fuser roller or a fuser unit which includes a fuser roller.

PM display conditions

The conditions of the PM display consist of the codes of the 08 Setting Mode for “the setting value treated as a threshold of the PM display”, “the counter indicating the current number of prints and driving time” and “the setting value which determines the display conditions”. The PM timing is displayed when the counter exceeds the setting value according to the display condition based on “the setting value which determines the display conditions”.

• Setting value treated as a threshold of the PM display
Notes: When “0” is entered as the setting value, PM timing is not displayed.

FS-08-6190: Setting value of PM counter [process unit (K)]
FS-08-6191: Setting value of PM time counter [process unit (K)]
FS-08-5554: Setting value of PM counter [developer material (K)]
FS-08-5555: Setting value of PM time counter [developer material (K)]
FS-08-5562: Setting value of PM counter [parts other than the PM parts of the process unit]
FS-08-5563: Setting value of PM time counter [parts other than the PM parts of the process unit]

• Counter indicating the current number of prints and driving time

FS-08-6194: Current value of PM counter [process unit (K)]
FS-08-6195: Current value of PM time counter [process unit (K)]
FS-08-5568: Current value of PM counter [developer material (K)]
FS-08-5569: Current value of PM time counter [developer material (K)]
FS-08-5576: Current value of PM counter [parts other than the PM parts of the process unit]
FS-08-5577: Current value of PM time counter [parts other than the PM parts of the process unit]

• Setting value which determines the display conditions

FS-08-6198: Switching of output pages/driving counts at PM [process unit (K)]
FS-08-5581: Switching of output pages/driving counts at PM [developer material (K)]
FS-08-5585: Switching of output pages/driving counts at PM [parts other than the PM parts of the process unit]

For example, you can set the conditions of the PM display of the [process unit (K)] as follows.

PM display by specifying the number of prints	1. Key in “0” for FS-08-6198 (Switching of output pages/driving counts at PM [process unit (K)]) 2. Key in the value of the number of prints for the PM display other than “0” for FS-08-6190 (Setting value of PM counter [process unit (K)]).
PM display by specifying the driving time	1. Key in “1” for FS-08-6198 (Switching of output pages/driving counts at PM [process unit (K)]). 2. Key in the value of the driving time for the PM display other than “0” for FS-08-6191 (Setting value of PM time counter [process unit (K)]).
PM display by the earlier one: when the number of prints or the driving time reaches the set value	1. Key in “2” for FS-08-6198 (Switching of output pages/driving counts at PM [process unit (K)]). 2. Key in the value of the number of sheets for the PM display other than “0” for FS-08-6190 (Setting value of PM counter [process unit (K)]). 3. Key in the value of the driving time other than “0” for FS-08-6191 (Setting value of PM time counter [process unit (K)]).

If the value of FS-08-9891 (Warning message on the touch panel when PM time has come) is set to “0: No warning notification”, the PM display is not performed regardless of the settings above. (Default value is “1: Display warning notification”)

PM display contents

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 developer material (K): 0080
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 peripheral parts of the process units (K) and developer material (K) reach the maintenance time, the 4-digit hexadecimal number code will be “0188” in hexadecimal numbers: 0008+0080+0100=0188.
