I'm curious what you are trying to accomplish. What model(s) are you working with?

I try to gain access to extended service "mode" where you can adjust more than you adjust in sim mode, for instance cannon, xerox allow more access for a tech, `I am working with range MX

Re: Sharp copiers service serial connector

You still did not mention models. Typically that serial port serves no purpose in the field. Personally I believe that it's used by the manufacturer to preload firmware or other data, but that software won't be available to any of us. Like the parallel port on many of the older Canons. =^..^=

Re: Sharp copiers service serial connector

There is a mode called special sim, or service sim mode for deeper adjustments. We had to call sharp to get it, they don't put it in the manuals because you can reset some serial numbers and counts and other such things. If a morally questionable customer got a hold of that, they could really rip off their service provider. I used to have it but we forgot what piece of scrap paper it was put on. It's so rarely used by us techs. You can probably find it buried online somewhere or just call the sharp hotline.
Hope this info is helped you.

Re: Sharp copiers service serial connector

Why don't they provide it to you? You called the hotline?

Re: Sharp copiers service serial connector

This special mode you speak of will not let you change data in the e-prom. Use the original eprom that came with machine.

What makes you say that?
Granted I haven't done it on the models he was specifically asking about. That being said we have reset the counts in the eeprom in models like the MXM350.

Re: Sharp copiers service serial connector

Resetting the count is your business, but when you try to make the chip work in a different machine its Sharp business. They don't want you to move options (PS3 EXPANSION KIT
BARCODE FONT KIT
INTERNET FAX EXPANSION KIT
APPLICATION INTEGRATION MODULE

) that you would have to pay for to another machine.

If the machine does not have a 'hard' keypad, you will not be able to access the special sims; if there is a way to access special sims, it's being guarded like Fort Knox.
