What makes a good PCR (Primary Charge Roller) - Week 1 January 2020

So what makes up a good PCR (Primary Charge Roller), and what affects the PCRs performance, and how best can you maintain the PCR to give extended life, better print/copy quality, and probably extend the life of the OPC Drum/Drum Units too.

Few may realise it, but to manufacture really good PCRs is extremely difficult, as the core ingredients need to be perfect to allow for a perfect roller that transfers the correct uniform voltages to the OPC Drum. The structure of the PCR also need to be perfectly round, and no wobbling, or ridges, as this will all affect the functioning of the PCR. So to make a cheap PCR may be easy, but will it work well, probably not, and the eventual costs you may incur in damage to the OPC Drum and in trying to maintain the print quality by changing settings to compensate for this, will end up costing you more than if you just installed a well manufactured product from the beginning.

CET pride ourselves in not rushing the production of our PCRs, and we also test every PCT for the resistance, and for it to be perfectly cast around the shaft.

What tips have you got for the PCRS from your experience in the field.

CET Group Technical Chat Room/Forum/Blog - We are here for YOU

Hi All,  We have started a CET Group Technical Chat Room/Forum/Blog, where we can share good ideas, ask for information, make suggestions. We plan to do a post every week with practical information on matters and products that we feel can help you support your machines better in the field. 

Unfortunately we will not or cannot allow any abuse of any nature on the Blog, so please lets respect each other, and lets make this work for the good of all. So what do you have to say?
