MP760 carriage problem - loud noise

[lrj]

Hi,

I hope someone can help. While trying to clean out the waste ink pads (I had the "waste ink absorber almost full" message) I accidentally touched the print head while it was moving. I know, I know, I should have taken the power cord out. Anyway, now when I turn the printer on, the print head doesn't move and there is a loud machine gun noise. The error message is simply "error, turn the machine off & on".
I can move the print head side to side by hand.

I've tried moving the print head to the right hand side, then powering back on. I've tried removing the cartridges & the print head, and then powering it off & on. I've also tried taking the power cord out for 15mins, none of which helped.

I don't particularly want to take it apart - it seems like the print head assembly needs reattaching to the carriage (or whatever drives it)??

THanks for any help

I don't know the MP760, so I cannot tell what to do but maybe the service manual will be helpful? Link here: http://soft-manufaktura.ru/manual/hp/mp760sm.pdf

I just checked the link and it still works, even if it was posted more than a year ago in the service manuals thread. The manual might be a bit slow to load though.

Good luck with the troubleshooting.

THanks for that, the manual had one or two useful bits in it, but what I had to do in the end was take the printer apart using the great instructions here:

There were a couple of small pads on the right hand side that had come loose when I was trying to clean them, which may have been the cause of the noise if they were hitting the cogs. ALso there was lots of ink oozing around on the same side. I reset the pads & cleaned up the ink.

All good so far...

I'm wondering if maybe there is a problem with the timing strip. It's an almost invisible piece of thin plastic that stretches from one side to the other and goes inside the carriage. Can you make sure it is intact and clean?

Thanks for the reply. I had wondered about that timing strip, and whether the position of the carriage had been lost. But after taking it apart, putting the mini pads (purge pads?) back where they belong - (the ones near the little wiper blade), and cleaning a lot of waste ink up, the printer is all working fine again.

THanks for the help though.
