Hopefully I can help you get the printer from installing without being saved as a mass storage device before your customer notices but I have a few questions first:
- How are you wanting to connect this printer to the PC (USB, wireless, or Ethernet)?
- Where is the printer being saved in the device manager?
- Did you use the installation disc or the download from the website?
- What is the printer's actual product # from the back of the unit?
I trust you have done a lot of the basic steps, so try this trick:
- Uninstall the printer from the Add/Remove Programs
- Unplug the USB cord
- Run Disk Cleanup
- Reboot PC by shutting it down completely and turning it back on with the power button
- Create a second User Account with Admin rights from the Control Panel (to avoid any software conflicts)
- Install the printer's Full Feature from the website but customize the printer's installation only choosing the necessary components for printing and scanning
- Plug in the USB when prompted
Let me know if this works or not. I hope this helps!
