Printer warm up & calibrating... 100.01 also sometime if i print just pass the fuser and than 100.01 error code on.

Welcome to FixYa
Dear User
This error usually indicates a defective fuser. Turn offf printer for 20 minutes (to allow internal error circuit to reset) and try again. If the error persists, it could be due to a faulty thermistor, fuser heating element, or loose or open connection to the fuser. Sudden occurances are almost always the fuser assembly. The fuser assembly may be hot, allow to cool before removing it from the printer or injury may result. You can perform a heating element test by checking the resistance between the two heavy leads in the fuser connector. Resistance should read less than 100 ohms in most cases, an open circuit indicates a defective fuser. For low fuser temperature errors, check the smaller leads on the fuser connector to measure the thermistor resistance. At room temperature, you should read in the range of 50Kohms to 350Kohms at room temperature. It should not be an open circuit nor should it appear as a short circuit. In some cases this error can also be caused by a defective power supply or faulty DC controller board, but check the fuser first. The most cost effective method of repair is to replace the fuser assembly. Component parts are not readily available and fuser repair can become involved. Also be aware that early replacement of consumable fusers may require reset of the internal counters so the maintenance interval remains correct. Replacement fuser assemblies are available here- Fuser Assemblies or it may be time to consider a Maintenance Kit which contains the fuser assembly.

Hi,

Is it a Lexmark printer?

I have seen this error many times on Lexmark printers.

This error normally means that you need to replace the ITU. I am a bit hesitant to tell you to go and get one and replace it, because it is an expensive part (around $600). Sometimes this error can go off due to a problem with the second transfer roller.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
