Hp 7210xi printer ink carriage circuit foil repair
Can you explain how to disassemble & repair the ink carriage flex circuit board on this printer. The circuit has been punctured by the spring wire that helps hold the black ink cartridge inn. I also need to know how to secure it better. It's falling out.

Liquidrage, While jaiku's quick response that this is not repairable is accurate, that doesn't mean it's not replaceable. You will need to replace the entire carriage assembly. I offer this part, and many others on my web store. Simply click here:7210xi carriage assembly I have priced these carriage assemblies at other online vendors, and you can too! They normally cost around $100 or better. But, I wanted to make repairing your printer more desirable than replacing it, so I offer my printer parts at more reasonable prices. Check it out, I think you will like what you see!

Check the flex cable that connects the carriage assembly to the main board. This flex cable contains about 23 links and you may have a few that are broken. By "carriage assembly", I am talking about that assembly that houses the print cartridges. If you have a few broken links, you can try repairing the cable, but it may be less time consuming to buy and replace the cable.
The printer carriage assembly is the part of the printer that your ink cartridge snaps into. Get some alcohol on a lint free cloth and wipe off the back of the printer cartridge where there are a bunch of copper colored dots. Also wipe of the part of the carriage assembly where those contacts on the back of the ink cartrige make contact. If that doesn't work then the flex cable to the carriage assembly is probably broken and then the printer is unrepairable due to cost of repair versus replacement.
I have had similar problem with my HP C6180. Over several months I have replaced Lt. Magenta at least 6 times. Finally I got a "Cannot Print" message after the 6th full cartridge. I tried removing/replacing cartridges, doing a hard reset, and clearing the hardware failure status (press # and *, enter code 1,2,3, scroll to 'System Configuration' press OK then scroll to 'Hardware Confifuration) - all to no avail.
I decided to remove the BIOS battery. Only do this if you're ready trash your C6180 and able to buy a new printer immediately! Remove 2 the black screws holding the left side panel in place and remove it to reveal the circuit board. Remove 5 silver screws securing the circuit board, and carefully tilt it up. On the back side, center front, is a silver 3 Volt Lithium battery; remove it. Cover the printer and let stand overnight. I did this, and when I put the battery back in and powered up the printer, error messages were gone, and it printed normally. I was lucky, but if you're prepared to take a total loss on your C6180, this might just work. My theory is that the hardware "forgot" it' error message.
You may need a new carriage assembly, with the ink removed, with a mirror you can see down in front where the ink cart. circuit board contacts the carriage. Each slot should have 4 gold wires all of them straight. Bent ones can be straightened carefully, any missing, you'll need a new carriage assembly, a shop repair.
Open the printer cover>press the button with the ink logo/picture and the carriage will move to the middle and stop. Open the cover of the releveant ink you want to change and remove it. remove the strip with the arrow on the new cartride (should tell you how to do this on the box or foil wrapper), and gently push the new catridge back in place. Close the ink cover then close the printer cover then press the ink logo again. This should send the carriage back to the right hand side. Some models then automatically send out a test page.
I tried all these steps and it still did not work was ready to throw the printer out from frustration. Instead I traced what I did when I had the jam. I believe if the factory can fix it so can I. My printer is now working and it was so simple yet HP does not tell you how to fix it.
