hello
i replaced the formatter on my hp cp5225dn laser printer.
the service manual says to use hexprint.exe or hpnpf to update the serial number and page counts.
where can i find these files?
anybody have an example file that i would need to send to the printer using these apps?
thanks
tim

Typically I have used a PJL file to update the serial number if that option is not supported in the service menus. I will send you some details via private message. I do not want to post on open forum as unwary users can get into big trouble if file formats are not correct. Moderator must enable PM before I can send it to you.
