I have an older Dell keyboard - no problem at all! Seems since the HP mouse appeared...but this may have happened BEFORE that, not sure. Once or twice, you think it's a fluke!

And yes, you know what Dell rhymes with...LOL.. NO aftermarket parts, so you're paying NEW price for a drum cartridge for an older printer likely not worth that much...

I did track down a remanufactured cartridge in CA for 1/3 the price- and it is working fine!
