I had a "carriage jam" error message.
My son gently 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, took the drive belt off/put it back on (not easy), and found
nothing wrong with it. So, I 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.

Why one anyone purchase an HP printer. They are tempermental. The ink is expensive. The printing is excellent when they work but need to hope your breath and pray when printed document needed. Suggest anyone serious about having working printer always available buy from any other manufacture.
