WHY NEED TO REPLACE IMAGING UNIT IN CLP PRINTER SERIES 320


If you are worried about opening the printer or welding, you can simply buy an easy reset chip from Amazon or eBay. No welding is required and the installation takes only 1 or 2 min. Just peel and stick the chip.

Search for DRUM RESET CHIP or PEEL STICK DRUM RESET and you will find many premade reset chips.

Is ti possible to reset the imaging drum counter for DELL 5100cn printer ?


No, but you can find a replacement chip for the unit online, and replace if the image quality was not too bad before it locked you out. The chip is on the side of the drum unit and is easy to replace. It looks like a 1-inch diameter brown circle.

There really isnt an easy way to do that.
The transfer belt assembly starts off with a fuse on it to blow immediatly on install, and a counter that is internal so that it will end of life and have to be replaced. It's really not a convience counter but an obsolence counter.
