Hi, I have a question I hope some can help me out with. I`m checking some toner cartridges for toner on a HP LaserJet 4050. I notice when I take out the toner cartridge and Install another one the printer does not record the amount of toner from the replaced one. I know some cartridges have between 20%-85% toner but the printer does not record that on the configuration page, it still records the amount of the original one removed. How do I get the printer to record the exact amounts, I would like to check various toner cartridges for amount of toner left.
Another question is, I`m running test pages on various HP LaserJet 4050`s and the HP logo on the background sometimes comes out real nice and on some printers it comes out faded or no logo at all. How do I ajust the printers to show the watermark HP logo on the test pages.
Thanks for any help
