A MX-500GT is listed for Europe/Australia/New Zealand. Is Lordegan in Iran? The service manual lists other supplies for the Middle East but I'm not certain which toner is for that area.

SMEF/Taiwan/Africa/Israel/Philippines = MX-500FT
SESC = MX-500CT
MPE = MX-500BT
Asia/SRH = MX-500AT

Is that blue crum chip OEM Sharp? Ours are black and have the Sharp logo melted into them. If the chip is generic and all you are doing is putting on new generic crum chips then that might be the problem.

Before I entered the code 88-01, the device worked with the same chipsets!
Now gives the code F2-70?
I tried several different chipsets but it didn't work?

I am not sure what this is:

"option 88-01 in the settings. "all memory clear"

I have worked on the model since it came out and I am not familiar with an 88-01 all memory clear. Is this one of those hidden sims that shouldn't be used?

As I do not know what memory has been cleared exactly I can't be sure what to tell you.

Again, are these chipsets OEM Sharp? Are you simply changing chipsets and not installing a new OEM Sharp toner? If you can answer these two question it would give us a better idea of how to figure out the problem.

This is a Sharp that still has "super secret service mode". I think SIM 88 is only available there. You can do all kinds of cool (and dangerous) things in that level.

The only thing I ever used the secret sims for were to correct meters that techs accidentally zeroed out on the Cougar series. First you had to find the sim and then convert hex to dec or the other way around. If you never had to do it then you have 6 extra months you will live.

ali may have cleared something that has caused this issue. Process Control, toner level, toner counter... IF he could get a 22-6 he may find zeros where there should never be zeroes.

Attention:
"Do not use this code (88-01) on your device for curiosity !!!"

[ali.nadri]

The hardware of this device is healthy.
The code (88-01) changed all device settings to zero.
Now I do not know which zero should change.
Which code should I change to identify the cartridge?

That's SIM 55, soft switches. Those are not counters. Whatever switches and bits you changed needs to be changed back. These are not listed in any manual.

I will see if I can find out what those soft switches are for.

If would be really really helpful if you would answer questions. If you keep refusing to answer questions and keep posting Help me Help me, you will find that people will start ignoring you.
