52 error hp iiip (3P)

After 15k pages on my 14-year-old printer I started getting subject error. This forum helped me understand what was happening. I must say there are an awful lot of screws to keep track of and there are many circuit board modules to remove. However, it is straightforward.

I checked the motor and wires, put it back together and got error message 12 (forgot to put the cartridge back in) then got error message 52 again. There was some discoloration on the back side of the board but not excessive.

I took it apart again and ordered the scanner motor RG1-1771, put it in and again; this time error message 51; what a sickening feeling. Took it apart again and found I had not plugged the photocell/laser cable in on the upper board.

I'm thinking you got the scanner motor elsewhere. Our instructions leave that fiber optic cable connected. Don't want the end user breaking it and there is really no need to disconnect it to replace the motor. We probably have a 99.98\% success rate with that kit.

In hind sight you are probably right, I could have left it connected. You do have to remove the board it is connected to get to the cover over the scanner motor though. One thing for sure you wouldn't forget to connect the cable and have to disassemble the printer again. - tmholmes
Wrong again. You do not have to remove the board or all the connectors. In our video, we just have you remove 3 of the connectors and leave the board attached. We found that the less you tell the customer to remove, the less chance that they will input another problem.

If I understand you correctly, you mean leave the cable attached to the board when moving it. You do have to remove the mounting screws holding the board and swing it up and away from its mounting area to expose the plastic cover over the scanner motor. I can see no other way to get to the motor, at least on my printer. - Anonymous
