There was a communication error with the receiving fax machine due to poor telephone line conditions. Solution

• Set the receiving machine to receive at a slower transmission speed
• If the session fails after sending several pages of a large document, resend the document as several smaller documents.
• Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.

And I have exactly the same problem too that has happened in the last few weeks.

I've tried reinstalling the software/drivers and resetting the printer to factory settings but no joy. An upgrade either windows or HP must have caused this!

This means one of the cartridges is defective, they cant align if they cant print. What i did to fix this problem is insert 2 working cartridges and get it to align properly, even if they are low on ink, then lift the cover and the cartridges will move to the center. When this happens pull the power cable out, then insert the full non functioning cartridge. Plug the power cable back in. I tried this with a color cartridge, the color cartridge was non functioning but i was able to print in black. Basically you align the cartridges and then swap them so the printer thinks they are still aligned. The color still doesnt work and it is probably a defective color cartridge.

I got the same error, and had it for months. open the ink door where it says office jet pro, it folds towards you, wait for the ink cartage to position to the left, then look inside and far to the right, and see if there is a wadded up peace of paper inside. Reach in and pull it out, it fixes the problem

I had a "carriage jam" error message.

My son wiped down the metalic strip that tells the carriage where it is. It worked for a couple of days and then the "carriage jam" message came back.

I took my 7210 apart, found nothing wrong with it and put it back together. I noticed that if I pushed the print carriage all the way to the left, closed the lid, and pressed "OK", the print carriage would move a couple of inches to the right. It did this repeatedly. I figured the motor was working, but there was too much friction on the carriage. I put some 3-in-one oil on my finger and put a thin coat on the front, top, and back of the rod that the print carriage rides on. I then ran the carriage back and forth about 20 times. I closed the lid and it works fine.

I had the same problem with my DVD player. The head was hanging up on the two chrome plated rods that supported the head. I put some 3-in-one oil on the rods, ran the head back and forth, and it has worked ever since.
