As the title says, we have a 190F which shows out of toner. Have replace toner cartridge (often), main board and both sensors that detect toner in the cartridge, has anyone else had this on this lovely machine!

Re: 190F showing out of toner
<br><br>Every new toner contains a little fuse (it is under two tiny contacts). When the user put the new toner into the printer, the fuse blows and the printer detects in this way that it has a new toner in; so if the toner has been for any reason only a moment into the printer cannot reset the message of add new toner.<br>You can test the continuity between the contacts.<br>Solution A: put in a brand new toner and use the other(s) first of the natural end (so the message is not yet displayed)<br>Solution B: find a pico fuse of the same value and put it place. (if you are a tech you know the value, it the same in fuser or TBU ). Aldo... In the minute that you're thinking of giving up, think about why you lasted so long ...
