How to reset Toshiba Studio 256se Total Counter?


Clearing counter
The counter indicating "current number of prints and driving time" used for the PM display function is
reset by entering "0" in it or clearing it in the PM support mode.
Notes:
Even if "0" is entered in the PM management setting value of the setting mode (08), the
corresponding counter for the PM display is not reset. Be sure to clear the counter in the PM
support mode when the maintenance is finished.
The reset condition of each counter is as follows:
• 08-6194: Current value of PM counter [process unit (K)]
• 08-6195: Current value of PM time counter [process unit (K)]
When the current value of "CLEANER/DRUM" on the main screen or "DRUM" on the sub-screen in
the PM support mode is cleared, the counter is reset.
• 08-5568: Current value of PM time counter [developer material (K)]
• 08-5569: Current value of PM time counter [developer material (K)]
When the current value of "DEVELOPER" on the main screen or "DEVELOPER" on the sub-screen
in the PM support mode is cleared, the counter is reset.
• 08-5576: Current value of PM counter [parts other than the PM parts of the process unit]
• 08-5577: Current value of PM time counter [parts other than the PM parts of the process unit]
• 08-6225: Number of output pages (Thick paper 1)
• 08-6226: Number of output pages (Thick paper 2)
• 08-6227: Number of output pages (Thick paper 3)
• 08-6228: Number of output pages (OHP film)
• 08-6244: Counter for tab paper
• 08-6247: Counter for envelope
When the current value of "FUSER" on the main screen or "FUSER ROLLER" on the sub screen in
the PM support mode is cleared, the counter is reset.
Notes:
The following counters are cleared by executing the EPU replacement mode.
08-6194: Current value of PM counter [process unit (K)]
08-6195: Current value of PM time counter [process unit (K)]
08-5568: Current value of PM counter [developer material (K)]
08-5569: Current value of PM time counter [developer material (K)]

How do I change the pc drum on a di 2010?


Hi to replace the drum on the machine you will need to do the following
select the tech rep mode then counter-pm-pc life press the clear key to clear the counter value turn off the power. Open the right side door slide out the drum unit from the left and right side of the unit remove the four silve screws two at each end now seperate the top part from the bottom part the top part holds the drum and the bottom part is the developer unit and holds the developer
you can buy the top part as an assembly then reinstall the new drum to the bottom developer unit put back the four silver screws you took out earlier and then put the unit back into the machine
You should replace the developer if you are replacing the drum at the same time now the unit is back in the machine turn on the power select tech rep mode then function f8 and then press the start key ONLY PRESS F8 if you replace the developer
you will also need to go into tech rep mode counter pm developer press the clear key to clear the value
turn off machine wait ten seconds turn back on this resets the counter
Tech rep is normally user counter then stop 00stop 0 1 press one after the other

error 990


sc990 is a general software error and could be caused by a number of things.

Is the copier very dirty, or are the PM (preventive maintenance) parts past their recommended counters? The copier may just need some new process parts (drum, charge roller, developer, etc.) and a good cleaning.

Does the 990 happen when you are printing or scanning? It could be an error with how the machine interfaces with your network.

Or, it may be a system firmware issue and the firmware needs to be updated or flashed.

developer....


When developer goes bad you use more toner for one thing, but the main sign is a gray background in your copy. The print should be black but appears to be gray. The ricoh 350/450 was always noted to leak toner and developer as it runs. Check your machine and see if you see any small piles of toner, which also has developer in it, in the machine. Ther are small seals made of felt that need to be replaced if you have this problem. These seals rub against the drum sides....Good luck.
