HOW TO CHANGE TRANSFER ROLLER ON A XEROX PHASER 7800

The message is caused by the fuser having had 100,000 pages or so through it.

It will be pretty much worn out, and should be replaced.

The transfer belt also has a similar pagecount limited life, and also the pickup/separation/transport rollers would benefit from replacing (they can get 'flat spots' on them

. they replace a certain number of pages printed by the manufacturer data
maintenance kits are easily user installable and come with a fuser assembly, transfer roller, and pickup, or feed/separation rollers.

Hello, The fuser or fuser roller is what actually bonds or melt the toner on to your paper. There is probably some type of temperature sensor, that senses the temperature of the fuser. If its not hot enough or just plain dead, it will give out an alarm similar to what your getting. You probably need to replace the fuser unit. You have a lower fuser and an upper fuser. You might be able to get away with just replacing the upper roller. The roller has a heating element inside and that's what probably defective.
Hope this Helps
Thank You for your feedback

Hello,

Cycle power, try cleaning the CTD (ADC) sensor and toner full sensor. This is what Xerox has to say about the NVRAM failure: On the front panel, press the key labeled i to view information about the error. Record the error code number. Turn off the printer. Reseat the fuser. Reseat the imaging unit. Reseat the toner cartridges. Turn on the printer. If the error continues to be displayed contact service. To be on the safe side you can follow the instructions here on the procedure to replace the transfer roler: http://office.support.xerox.com/SRVS/cgi-bin/webcgi.cgi Good luck
