Hp 7210xi printer ink carriage circuit foil repair

Congratulations, it probably has the best inkjet printer mechanics in the world. Anyway. The contacts in the carriage are tiny rods on springs. They can loose contact both in front due to ink, or in the back due to softened springs or oxidized carriage PCB. You have to dismantle the carriage to strengthen the springs and to clean their footprints. Second version: probably the flex cable from the main board to the carriage got cracks in the conductor and needs replacement. It happens often with old or heavily used inkjets/design-jets.

C4557-80075 Cable - Carriage assembly flex cable - 40.3cm (15.9in) long

Perform a hard reset of printer electronics to factory defaults and/or reinstall the driver. If still bogus contact Canon tech services but you may need a new printer. if nothing works.

Put the whole thing in the nearest dumpster, go purchase a printer that uses toner instead. I work on copiers for a living and have learned not to work on any printer that uses liquid ink. Even the technicians who work for the maker of your printer replace the commercial printers that use ink with a refurbished machine, and usually make no attempt to repair them in the field.

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.

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 hope this helps

Hi,

Please letme know what do you mean by Flex cable.

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.

i would trace the line back and put a small wire to replace the broken path.
