i replaced the toner cartridge on my mfp 28w black and white printer some time ago. the printer keeps telling me toner low. how do i reset the toner counter?  and what does the supplies light mean? to be honest, i have had problems printing with this pos printer since i bought it years ago. it will hang up and i will open the top and close it hard and it will start printing. or i unplug it and plug it back in and it will print.   while i am at it, i have an hp 23755 inkjet printer that says it is low on ink. when i replace the ink cartridges, how do i get it to acknowledge new cartridges.
