C35 style
(Pro55 shown)<\/p><\/div>\n

Perhaps the most prolific and popular Xerox style of copiers\/MFDs, the black and white C35 style started selling about 15 years ago, and through half a dozen new families of models, this series continues to be sold today as the WC-5890 family. One of the most difficult problems to cope with remains memory loss or corruption. The NVM (Non Volatile Memory) is protected by a 3 volt lithium battery and when that fails, as is true for most copiers, the machine loses its memory and needs to have the memory restored one way or another to get it back up and running. Let\u2019s have a look at some of the fault messages you may see and the best steps to try to remedy the situation.<\/p>\n

First, an ounce of prevention is worth a pound of cure. Make sure to keep a current copy of the machine\u2019s configuration report handy (keep a copy in a pouch on the rear cover of the machine).<\/p>\n

You\u2019ll be happy to have this if you ever need to reload the system software, because you\u2019ll need to know which version the machine was equipped with in the first place. Also, you\u2019ll want to know with confidence which optional services are loaded and what the network configuration settings are supposed to be. You can also check the system software level by pressing the \u201cMachine Status\u201d button and then touching the \u201cMachine Details\u201d choice on screen. Read the version listed under \u201cCurrent System Software.\u201d<\/p>\n

It\u2019s also important to back up the memory on these machines if the opportunity ever arises. If a tech with a PWS (Portable Work Station) laptop is working on the machine at any point, ask them to run the NVM Save\/Restore utility and load the file onto a backup disk. Keep this disk in the pouch on the machine. This disk is known as the \u201cResident Diskette\u201d (older models kept this on a floppy disk). This way if the NVM ever gets corrupted you have a backup file so someone with the PWS can use it to run NVM Save\/Restore to restore the settings from the backup file.<\/p>\n

If you ever need to reload the system software on the machine, the process all depends on which model you\u2019re working on. You can find the software .dlm file on the excellent Xerox support website: www.support.xerox.com and there enter the model of the machine and choose the link below your model for \u201cDrivers & Downloads.\u201d Scroll down to the bottom of the screen to find the firmware. You can download the newest software in a zip file and in most cases there are also \u201cRead-me\u201d files available in pdf format that explain how to load the system software. You will need to refer to the machine or to a configuration report (as mentioned earlier) if possible to know which version of software will work with your model and configuration. If you don\u2019t have a way to check which version, here are some guidelines as to which versions are used for which configurations:<\/p>\n
