Have a 843.00 s error message after replacing fuser. How can I fix it?

We replaced the fuser and now when I turn on the printer, the top screen reads "843.00 Service s" and on the next line "an". Not sure how to go about fixing this problem.

SOURCE: 123 Service Fuser Error - Lexmark C762 Colour Printer

This error refers to a thermistor error with your machine (assuming that you meant 923 error and not 123 error). Chances are that you will have to replace your fuser. Part number is: 56P2851.

To replace open the right side door (the one with the blue handle) and the lower door below it. Your fuser is the one with the 2 blue clips. Pull clips down and remove fuser. Replace fuser and push clips into locked (upright) position and that is it.

Hope that helps.

SOURCE: Lexmark C772n - 127.07 Service fuser error

I searched the Technical Manual and there is no explanation of the code. The user manual simply says there is a printer failure. They ask that you turn the printer off, wait 10 secs and then restart. Then call 1-800-LEXMARK and they will tell you about the code.

Given that your printer is saying Service Fuser, it is highly likely the fuser is ready for replacement. The fuser is the component that heats to high temperature to fuse the toner to the paper and complete the print cycle.

Xerox 6280 gets error message replace fuser kit, it was replaced and still has the same message


This is an easy one.


The original fuser supplied with the printer DOES NOT have a counter chip. Instead, the PRINTER assumes that when the number of pages printed reaches the level at which the fuser needs to be replaced, the printer issued the REPLACE FUSER message.


If you replace the fuser with another that has come OUT OF a new printer (i.e. a 'PULL' from a new unused printer), since it has no counter chip of it's own, the printer assumes the fuser pagecount is the same as the printer pagecount (because there is no information to read from a fuser chip), and still wants the fuser to be replaced.


A new REPLACEMENT fuser from XEROX, or a CORRECTLY refurbished fuser WILL have a counter chip, and therefore clear the REPLACE FUSER message.

When I turn the Printer on, it will initialize and then display an error message "50.7 fuser error" and will not get to 'ready mode' for printing


1. Turn the printer off, wait 10 minutes, and then turn the printer on. 2. If the message persists, reseat the fuser. If that does not work, replace the fuser. To check the fuser, turn the printer off and remove the fuser. Measure the resistance between the fuser connectors. If it is not within the proper range, replace the fuser. If there is not continuity between the fuser connectors neutral and hot with the fuser removed, replace the fuser. If the problem is not related to the fuser, replace the engine controller board. http://printertechs.com/tech/error-codes/error-codes-50-59.php

Error message Engine Fuser Overhaet


The fuser rollers (large orange rubber rollers visible with top cover open) are getting too hot, or the temperature sensor/wiring is faulty and misreading the temperature. Assuming sensor is okay, check the exhaust fan is running and expelling warm air as over time it will clog with dust and the fuser unit won't be cooled effectively.
