I've an HP deskjet ink advantage all in one series k209a printer, the computer is showing the message that the cradle is not moving and its a paper jam there or something else is obstructing but I checked there is no paper or anything visible stopping the movement of cartridges,

I opened the front door and saw the cartridges are getting stuck and moving in the same spots themselves, nothing visible is stopping them, its like the cartridges make back and forth motion around the path and hit the sides again and again making collision sounds...Is it the printer processor's fault or the conveyor assembly is faulty?

This isn't an uncommon problem. Inkjets of all types have a reset location or home position where the printer must move to on power up and where it sets idle while on but not printing. There are sensors mounted all over the carriage area and paper path. One of the reset routines gives the jets a little squirt before starting a page, this ink goes into a little catch cup and has a wiper blade to clean the face of the ink cartridge. This whole area tends to get really gummy and can lock the carriage in place. Some alcohol on a q-tip should loosen it up and then clean up can commence. If you aren't doing it yourself, it is about a one hour job and can cost up to $100. Some of these things retail for much less and others only a bit more. I've actually seen a unit where the dried ink fused to the cartridge and the rubber wiper. User ripped the cartridge out and destroyed the spitoon. (what else would you call it) HP is not known to make things easy for the user to do the maintenence but there are some tricks to use and as each new line is released, newer methods are outlined in their service manuals.

why does it slam once and again moves smoothly along the same path on the cradle shaft?, If something is stuck there the cradle won't move along the shaft at all?...it seemed like the sensors are getting misdirected due to the moisture caused in rainy days? Because it fixed itself once...okay lets try your q-tip method!

That ink is like sawdust, it seems to get everywhere. Look around inside if you can and find the position sensors for the carriage. The reset process starts by first moving the carriage to the home position and has a sensor that needs to be activated, then it will move over the ink cup ansquirt and the return home and reset to idle. If the sensor gets blocked and it's timed to only apply current to the motor for a certain length of time without the home sensor being activated. The current releases and it slips to the reset position. If the reset sensor is also dirty or obsured, the that little onboard diagnostics says there's something inthe carriage path, blocking proper motion of the carriage. One fault I've seen was a repeated slamming of the carriage to the far right.

The problem might be caused by some dust or it happens if it is not in use since long time.
