My di 3510 work normally, until i replace a new bottle toner, then the cof32 code appear, i also found the new toner powder is heavier than the old powder, is that the powder stuffs inside ?
what should i do?
thank you
Has the developer been replaced and the F8 function run and has the counter for the developer been reset. Also the drum should be replaced. at the same time. If this was already done did the person doing it use a vacuum cleaner to remove the old developer if so the Sensor for this code was destroyed by the static electricity from the vacuum cleaner never ever use a vacuum cleaner to remove old developer
Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f
