I hope this post gets on the forum—I tried updating yesterday, but somehow my entry does not appear in this thread…
After damaging an InkJetMall refillable cart for our 3800 printers, I filled and installed the new #7 (LC) cartridge with Piezo-Flow, and inserted it in our 3800 #1. The printer refused to recognize the cart, as well as #'s 8 (LM) and 9 (Y). MANY attempts produce the same result. I even followed the instructions for re-setting the printer—unlock all 9 carts, slide out waste ink tank, turn off printer for more than 3 minutes, turn printer on, slide in the tank, close its door, insert carts in numerical order, close cart bay door. Didn’t help, tried multiple times.
I was worried that a leaking LC cart had spread PF inside the printer last week, possibly affecting the electronics or other critical parts. So I removed carts 7,8, and 9, and replaced them with Original Equipment Manufacturer’s (Epson) carts. Bingo, all carts were accepted, so did a few nozzle checks, then a test print to confirm. Because 6 of the 9 carts are flush carts, the print was kind of pink-y, but otherwise fine. The printer seems to work well, disproving the possibility that 3800 #1 was damaged by the leak.
Then, I took the entire set of IJM carts to our 3800 #2. Once again, carts 7,8, and 9 were not recognized. While I was lifting the bottom edge of the installed carts, as the instructions direct, I noticed that when lifting the yellow / #9 cart, ALL the carts were suddenly recognized. Firm upward pressure is required—as soon as I reduced the pressure, all the cart positions flashed, unrecognized. So I cut a piece of some firm foam packing material and stuffed it under cart 9. All carts were then recognized, and I successfully ran a power cleaning to push PF into the lines and head. Waited a few minutes, as Dana suggests, to avoid over-taxing the head, and then repeated. When the 2nd cleaning was completed, I ran a manual nozzle check, and found that some ink still remains in the head, though diluted. Did another power-cleaning, and retested: all remnants of color gone. Success! Then, changed from Photo to Matte black ink, and repeated the series of three power-cleans to flush the Matte channel.
I then took the set of IJM flush-carts to 3800 #1 and finally had success here the same way: I had to wedge something underneath the Y cart to hold it tight against its contacts. Only that cart required this treatment—in two different 3800’s— so I’m wondering if it may be defective.
The lesson here seems to be that a single cart that is not seating well against its chip-reading contacts may cause all the others to not be recognized.
Dana, I hope you see this. I’m puzzled why my posts seem not always to make it to the forum.
