Workcentre 7535 boots displaying 7525 branding

Jump to solution
Product Name: WorkCentre 7525/7530/7535/7545/7556
Operating System: Windows 10 x64

I have a Workcentre 7535 that was given to me by a parent of one of my special education students. For the last year or so, it has run without any lasting issues until a few days ago. I turned the power on like usual, it displayed a different product: Workcentre 7525Although this is incorrect in my mind, the machine begs to differ, because when the power-up ritual is complete, a roaring cacophany of beeps and a flood of error code windows appear. Long story short: any consumable read by a chip is being rejected (e.g., toner).

Usually, I never need to get on forums like these because of how well the community approaches so many problems and solutions. I got to say...I am stumped on this one. I have gone as far as wiping the hard drive clean and altbooting into a forced upgrade with the latest firmware and it still boots up and displays "Workcentre 7525" on the screen. 

Everything seems to be working fine except for the fact that my Workcentre 7535 believes itself that it is a Workcentre 7525. How can I get my Workcentre 7535 to diplay the correct product number?

Hi,

It is possible that the battery on the SBC board to be drained and must be replaced. Normaly you need a tech because after replacing the battery one machine NVM must be setup.

Would you by chance know the protocol for draining the SBC board battery? I ordered a new one and it is on the way. I will let you know if it works.

I am afraid that replacing the battery did not influence any visable changes in the machine. The Device Model is 7525 when I press Machine Status, even though the branding on the machine says it's a 7535. It ran just fine until one day it started booting with the wrong Device Model.

Unfortunately, the only way you can get this problem fixed is to have a new SIM card made specifically for the 7535. Once you load the correct SIM card, it will display the correct branding. The problem is that the machine boots and reads an incorrect or corrupt configuration. If you have a SIM card (the slot is in the same area as the ethernet port and mine is colored yellow), then you can throw that one away because it is corrupt, damaged, etc. Maybe try booting without the SIM just to see if the fix is that easy. If you do not have a SIM card in the slot, then you will need to get one in order to fix your machine. No two ways about it. 

You will need to call Xerox and work it out with them regarding how to order a SIM card for the 7535. To my knowledge, it is not expensive. When I had this issue, they accidentally sent me a SIM card for a 7545 or something like that, and I had to send the SIM card back and wait for the correct one. They did not charge me because of all of the time I had to wait for them, but even if they do, it should not break your bank. 

Word to the wise, do not let anyone plug USB devices into the machine that are not supported. In my case, someone thought Wi-Fi could be achieved by plugging in a USB wireless network adapter into one of the USB ports and it corrupted the configuration.

I heard there is a list of basic nvm settings that you can enter manually

Another option is to save the nvm settings from the same model on a USB and transfer them via mega or Dropbox
