Downloading the new firmware to the product For support information about downloading new firmware from the Web, go to: www.hp.com/support/cljcp5525 The product can receive a firmware update when the product is in a READY state. The product waits for all of the I/O channels to become idle before performing the update. NOTE: If the firmware update involves a change in the format of nonvolatile random-access memory (NVRAM), any menu settings that are changed from the default settings will return to default settings. The settings must be changed again if you want them to be different from the defaults. Examples of settings that are affected in this way are tray types, default symbol sets, and Web-access alerts. The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for the product to reinitialize. The I/O transfer time depends on a number of things, including the speed of the host computer that is sending the update and the I/O method (parallel or network). The reinitialization time depends on the specific hardware configuration of the product, such as the number of EIO devices installed, the presence of external paper-handling devices, and the amount of memory that is installed. Finally, any print jobs that are ahead of the RFU job in the queue are printed before the update is processed. Use one of the methods described in this manual to update the product firmware.
