Yesterday while printing out some documents, the printer stopped printing black text. The cartridge gauge showed empty so I removed the black cartridge and refilled it. However, after re-inserting it, the gauge still shows empty and the printer still will not PRINT BLACK.. The printer is a HP Mod 4500 Wireless 4 way, the cartridge is a HP 901 Black. I suspect the machine has disabled the black cartridge ink injectors because of the "print gauge" showing empty (can it do this?) .. Does any one know how to deal with this problem? Thank you for reading this. Jim1. Either buy a new genuine HP cartridge or take your old one to a shop which can reset its chip. Even though you refilled the cartridge I expect you didn't reset the chip which it contains. Thus the printer reports the same (empty) cartridge to the printer driver.

2. Don't type all in capital letters.
Given in your initial post you are accustomed to refilling it (yourself i assume) another alternative is to purchase a "chip resetter" and/or a cartridge replacement that does NOT require resetting. Neither of these options are available from any manufacturer and should NOT be pursued while your printer remains under warranty. Not because they are dangerous but they will certainly void the warranty. In an earlier CH thread i posted a company that i have often used for these purposes and can highly recommend.They are located in the state of Georgia in the Atlanta area of the U.S.A. I am again offering their web site. If the geography permits you can contact them toll free or by e-mail to see what if anything they offer in that regard for your printer.
