This error message indicates the fuser assembly, which bonds the toner to the paper, is failing to maintain the needed temperature. A fuser is a consumable part, over the life of the fuser error printer you can expect to change a fuser several times. Fusers are sold as part of the preventative maintenance kit. Lexmark rates the life expectancy of a fuser around 150,000 pages, but a fuser can fail much earlier depending on printing conditions, paper jams, and the quality of the fuser installed. For a temporary fix, you can try turning the printer service fuser error off and back on again, sometimes the reboot allows the fuser to reset so you can print a few more pages. Usually the error message returns quickly; in that case you should install a replacement fuser. Fortunately, replacing fusers on these model is not difficult. (Remove the back cover, unscrew 2 screws on the fuser, unplug the fuser, and pull the fuser assembly out.) We have installation instructions available.

that we have another bad fuser, but is there something else that could be causing this error? Respond to this 0 Yes you could have recieved a bad fuser unit. The following is and taken from one of our service manuals that will help you to further test your machine should the fuser be ok. Note you will need a DVOM meter in order to test the fuser and the machine.A 922 error during a POR caused by low line voltage can usually be cleared by doing another POR. If the fuser lamp is lighting very dimly, check for a 220 V lamp installed in a 110 V machine. Check all the connectors to the exit sensor card and the lamp power connections at the left end of the fuser. Make sure the thermistor is making contact with the hot roll. Check the continuity of the lamp, the thermal fuse, and the fuser power cable. Check the thermistor resistance at engine board J8-3 to J8-4; it should be from 100K Ohms to 260K Ohms when cold; it may be as low as 2.3K Ohms when hot but increases quickly as the fuser cools. There should be no connection from either pin to ground. If the thermal fuse is open, the fuser and the fuser wiper may be damaged. Before replacing the fuser and the fuser wiper, check the voltage at engine board J4-16 as you POR again. It should stay at 0 until the 922 Error is displayed and then go to +5 VDC; if it does not,replace the engine board, the fuser, and the fuser wiper. Next, measure the voltage to the fuser lamp during a POR; it should be line voltage until the 922 Error is displayed, if it does not, replace the LVPS, the fuser, and the fuser wiper. If the voltage to the fuser lamp is the not the same as the line voltage,replace the LVPS. If the lamp, fuser power cable, thermal fuse, thermistor and lamp voltage are OK, check J4-16 to see if the engine board is sending the correct signal to the TRIAC. At POR this signal should go to +5 VDC and then immediately drop to 0 VDC until the fuser is warm; if it does not, replace the engine board. If the signal is OK, replace the LVPS. by aerolaser on Jun 24, 2009 at 8:35am Add comment Please sign in to comment Please sign in to comment Lexmark Optra S Buy discount ink Buy this printer More Lexmark questions © Copyright 2011-2016, FixYourOwnPrinter.com, Inc.
