preform ALTBOOT with proper firmware would be an idea.Originally Posted by dn_gustavo
Hi Phil, I perform exactly that right now. Same thing, 7525 model.
then you need the proper SIM card
My machine does not have SIM card. I'm in Brazil, in my country this equipment are sealed without contract and without SIM card.
The SIM card isn't related to being on contract or not, or whether it is sold or leased, or what county it is in or anything like that. It is part of the physical hardware of the machine. A SIM card is specific to the machine, it can't be used on different machines, and it is the item which MAKES it a 7525 or a 7535 or a 7545, etc... It is used when the machine is first "activated" to define what speed the machine is, and at that time, the SIM card is "locked" to that machine's serial number.
If the machine ever needs to have its software re-installed, you can re-use that same SIM to reactivate the speed, but it only works on the machine with the same serial number that it is locked to.
It is usually stored in a little secret "storage space" on the side of the tray 1 or tray 2 paper drawer, in case it is ever needed in the future. The same place you found the document in tray 1 you mentioned.
Without the SIM, you cannot adjust the speed of the machine. In fact, the whole reason for the SIM is to PREVENT ever being able to adjust the speed of the machine without it.
You can buy brand new "unlocked" SIMs from Xerox, but they are VERY expensive. And once you use it, it them becomes locked to the machine.
Reinstalling the software, or resetting NVRAM, are all reasons you then need to re-use the SIM.
Unfortunately, without the SIM, there is no way to change the speed from the slowest model. The slowest is always the default. There are zero nvram settings you can change to adjust the speed, ONLY the SIM can do it.
Thanks Brother... I knew they use a SIM card but this user poo poo'd it. Clearly he is an end user/ non Xerox tech..
You Sir are the one with the most knowledge on Xeron I have seen in CTN..
Thank again.
To the OP: don't argue with Caffeine .. he knows his shit on Xerox units.
Haha, thanks... Just Xerox, and just the ones that are technically FUJI Xerox.
OP may have been mislead by who he bought it from, too. I've heard so many stories like that. If he bought it new, any WC75xx machine would have the SIM tucked away in the paper drawer secret compartment. It would have to, there is no such thing as a WC75xx machine that doesn't use a SIM. But if he bought it used, it could have gone missing, and then who knows. It's a real bummer. The sales person may have not mentioned it, or they themselves may have been very uneducated about its importance, for re-setting the true machine speed, in the case of a software reload or NVRAM reset.
EVERY Xerox/fuji i have worked on needed either it in it to boot or to do such repairs.Haha, thanks... Just Xerox, and just the ones that are technically FUJI Xerox.

most times it is stored in it socket in the EMOD
Thanks for your help bro.Haha, thanks... Just Xerox, and just the ones that are technically FUJI Xerox.

Really I don't have the SIM card. When I replace the battery, I used the NVM factory list (in the compartment on tray 1) to reconfigure the machine, but the SIM card is not there.
Yes, this equipment was bought used.
Thanks a lot, everyone.
