 Welcome to BCH Technologies. This video is a part of video one of our Twin Chamber Review series. If you want to see the whole video, please visit the link below. We kept printing with the chip info on, and finally we reached HP's page limit on the black. We just hit OK, and the printer back to work. You can see the black become unknown, and the yellow magenta and the cyan still 10%. Now we're going to turn off the chip info. We go to set up, then preferences, and we scroll down to store anonymous usage information and turn it off. Remember, the printer has 10% of yellow, cyan, and magenta, at least I think it has. Let's see what happens if we print with the chip info turned off. We're on page 351, 10% of colors, no black, chip info off, everything's ready, and let's go. In the middle of printing, magenta is clogged. We did two heads cleanings, and we got a printer back to work. We printed about 200 pages. Now we're at page 557. The printer still thinks the ink level is the same as before. It's 10% of yellow, cyan, and magenta. Therefore, we can just fill and print forever. Keep an eye on the printout, and just add ink as needed.
