Well Xerox loves this machine for good reason and there have been two more waves of new models since then in which the fuser designs were nearly identical. The old fuser rebuild article is still good, but the addition of newer models over the years makes these worth revisiting. First we\u2019ll go over the part numbers for the fusers found in the newer models in this series. Then we\u2019ll touch on the importance of updating the firmware and how to go about that. Finally we\u2019ll go over the fuser related fault codes and temperature settings available to you in the NVM.<br \/>\nEach new family of models has its own part numbers for the fuser. The good news is that the parts in these fusers, including the heat roll and pressure roll, all cross from one fuser version to the next. The procedure for rebuilding each is the same as well. Here are the part numbers for the fusers for each family of models:<\/p>\n<ul>\n<li>C123 Family CC-C123\/C128\/C133, WC-M123\/M128\/M133, Pro123\/Pro128\/Pro133:<br \/>\n<strong>126K16480, 126K16481, 604K20342, 604K20343, 604K20344, 622S00191<\/strong><\/li>\n<li>WC-5230 Family (WorkCentre) WC-5222\/5225\/5230:<br \/>\n<strong>126K24980, 126K24981<\/strong><\/li>\n<li>WC-5335 Family WC-5325\/5330\/5335:<br \/>\n<strong>126K29391, 126K29392, 126K29393, 126K29394, 126K29395<\/strong><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>These models are all very finicky about the fuser temperature and the timing of the warm up cycle at start up. Customers need to be made aware that if the machine is in a cold room and you try to start it up, it is likely to fail to come to ready; it will time out and call a \u201cfailure to warm up in time\u201d type of fault code. Some of these codes require that you reset the fault from the diagnostic mode (which we will cover later in this article).<\/p>\n<p>Also we\u2019ve found out that on the WC-5335 family in particular, it\u2019s critical to update the firmware on the machine because they\u2019ve corrected a few problems relating to the fuser. One known problem results in the fuser running too hot. The toner will ravel on the page if you smear at an area of heavy background. Then the toner will start to offset on the pages and on the thermistors, which makes it get even hotter until the black sleeve-like coating of the pressure roll sticks to the heat roll and peels off in patches. The book says the WC-5325\/5330\/5335 machines should all be updated to software version 53.30.11 or higher.<\/p>\n<p>You can go and download the firmware from www.support.xerox.com (which is a great resource for anything which the customer needs to do, as far as changing administrator settings or reloading firmware, etc.). On the support site, you will enter the model of the machine and choose either \u201cSupport\u201d or \u201cDrivers and Downloads\u201d for the correct model from the list that appears. In this case choose \u201cDrivers and Downloads\u201d and scroll down to the bottom where the firmware choices are found. Download the zip file and unzip it so you can see the .bin file that the machine needs. The support site does explain how to upgrade the software from the network, but I noticed that the instructions about how to install the software using the USB is missing (usually they include a pdf or a text read-me file with instructions in the zip file), so here is how that goes:<\/p>\n<p><strong>Updating Software on the 5335 Family from a USB Flash Drive:<\/strong><\/p>\n<p>Create a folder in the USB flash drive and name it \u201cDWLD.\u201d Copy the .bin file obtained from the support.xerox.com website. It comes in a zip format, so unzip it and copy and paste it into the new folder. Make sure USB printing is enabled, and then turn the machine off completely. You need to turn off both power switches (one is inside the front cover). Plug in the USB flash drive into the USB connector on the control panel (if available). Note that if the machine doesn\u2019t have a USB connector on the control panel you will need to use the top one on the ESS PWB chassis on the right at the rear of the machine (it may have a metal shield held by one screw blocking). Next, hold down the \u201cEnergy Saver\u201d button while powering on the machine. Keep holding the button until the message \u201cDownload Mode\u201d appears. It will eventually say \u201cTransferring\u201d and later \u201cProcessing 1\/7.\u201d When the download is complete, the machine will reboot itself, a progress bar will show up, and the machine will come to ready. Check the software version by pressing \u201cMachine Status\u201d and then selecting \u201cGeneral Information\u201d followed by \u201cSoftware Version\u201d to make sure the upgrade was successful. Now you can power down and remove the USB flash drive.<\/p>\n<p>To clear some fuser fault codes and also to reset the HFSI (High Frequency Service Item) counters you\u2019ll need to go into the diagnostic mode. Getting into diagnostics is slightly different on the older models (C123 family), but it\u2019s still pretty close:<\/p>\n<p><strong>Entering UI (User Interface) Diagnostic Mode:<\/strong><\/p>\n<p>From the powered on state, hold down the \u201c0\u201d button for six seconds and then press the \u201cStart\u201d button while still holding the \u201c0\u201d button. The machine will prompt you for a password. Enter the default access number \u201c6789\u201d and press \u201cConfirm.\u201d The display will acknowledge that you are now in diagnostic mode (on the C123 family, the colors on the display will reverse). Next press the \u201cMachine Status\u201d button (or \u201cLog In\/Out\u201d for the C123Family). Select the \u201cTools\u201d tab, then \u201cSystem Settings,\u201d \u201cCommon Settings,\u201d \u201cMaintenance\/Diagnostics.\u201d This will bring you to the main menu where you\u2019ll find the memory settings (NVM) and lots of other important stuff. The HFSI counters for resetting fuser count and other High Frequency Service Items is found in \u201cAdjustments\/Others.\u201d<\/p>\n<p>Now let\u2019s have a peek at a list of the fault codes which have to do with the fuser.<\/p>\n<p><strong>Fuser Related Status Codes &amp; How to Reset Them:<\/strong><\/p>\n<p><strong>C123 &amp; WC-5230 Families: (C123\/128\/133, M123\/128\/133, Pro123\/128\/133, WC-5222\/5225\/5235)<\/strong><\/p>\n<p><img loading=\"lazy\" class=\"alignleft size-full wp-image-18396\" src=\"http:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/002graph-1.jpg\" alt=\"002graph\" width=\"610\" height=\"342\" srcset=\"https:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/002graph-1.jpg 610w, https:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/002graph-1-300x168.jpg 300w\" sizes=\"(max-width: 610px) 100vw, 610px\" \/><\/p>\n<p><strong>WC-5335 Family: (WC-5325\/5330\/5335)<\/strong><\/p>\n<p><img loading=\"lazy\" class=\"alignleft size-full wp-image-18397\" src=\"http:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/003graph-1.jpg\" alt=\"003graph\" width=\"610\" height=\"761\" srcset=\"https:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/003graph-1.jpg 610w, https:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/003graph-1-240x300.jpg 240w\" sizes=\"(max-width: 610px) 100vw, 610px\" \/><\/p>\n<p><strong>* Resetting Fuser Codes (010-320, 010-327, 059-315, &amp; 059-317)<\/strong><\/p>\n<p>Accomplished by resetting NVM code 744-220 to \u201c0,\u201d or 744-005 for the WC-5335 family.<\/p>\n<p>First enter UI (User Interface) Diagnostic Mode (read above for details).<\/p>\n<p>Once you\u2019re in the maintenance\/diagnostics menu, you\u2019ll see among other things a choice called \u201cNVM Read\/Write\u201d (NVM is Non Volatile Memory).

Select the \u201cNew Value\u201d column and input your new value (\u201c0\u201d). Select \u201cSave\u201d and the new number should now appear in the \u201cCurrent Value\u201d column. Choose \u201cCall Closeout\u201d to reboot. The machine will attempt to warm up the fuser again. If the condition that caused the fault in the first place is still happening, the status code will return after a few minutes of attempting to warm up.<\/p>\n<p>If you have a stubborn machine which keeps timing out when it\u2019s turned on in the mornings, a few folks have reported that changing the NVM memory setting 744-043 to \u201c1\u201d extends the allowable warm up time. This helps to get the machine to be more forgiving. Still, it\u2019s important that the owner of the machine keep it in a room that doesn\u2019t get too cold at night. If the room is too cold when they turn the machine on, it\u2019ll likely go into a fault code that requires a tech come turn the code off from diagnostics. You\u2019ll want to test the fusing closely after changing any fuser setting to make sure it still fuses under various circumstances because variations on the firmware could make one machine behave slightly different from another.<\/p>\n<p>There\u2019s one more thing that will prove helpful in checking a fuser you\u2019re about to rebuild. You\u2019ll want to know which pins are for which circuits within the fuser. There are two heat lamps that are actually joined into one lamp assembly to check out. Those both share a common return lead that goes through the thermostat (thermal fuse). If the fuser overheated severely enough, the thermostat will be blown and will need to be replaced. There are also two thermistors, a rear overheat thermistor and a center control thermistor.<\/p>\n<p>Here are the pin-outs for each of the fuser components for the C123 &amp; WC-5230 families vs. the WC-5335 family.<\/p>\n<p><img loading=\"lazy\" class=\"alignleft size-full wp-image-18398\" src=\"http:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/004graph.jpg\" alt=\"004graph\" width=\"600\" height=\"195\" srcset=\"https:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/004graph.jpg 600w, https:\/\/www.enxmag.com\/twii\/wp-content\/uploads\/2016\/05\/004graph-300x98.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>Note that the C123 and WC-5230 families are interchangeable, but on the WC-5325 the pin-out is completely different and they\u2019ve gone so far as to flip the connector over.
