Carriage jam - Turn machine on, get carriage jam message, however the carriage can move freely if moved by hand. If I close and hit enter, carriage sounds like it's moving, then I get the error message again.

Hi
Going to resurrect this old thread as my experience may be of some use.
My HP 7520 kept coming up with error 0x610000f6.
You could hear the carriage moving and clunking as it hit the end stops.
Thought it was probably the encoder strip or sensor took the printer apart and cleaned / checked both looked ok. reassembled the printer still no joy.
As I had the sides off the printer I noticed that the ink catch / cleaning tray seemed to not want to move (mentioned in post above).

with the side off the printer it is easy to move the tray. After a bit of wiggling the printer booted up ok.
It still errors every now and then but again a bit of fiddling sorts it out until next time.
I should strip it down and find the problem but as the whole ink trak is filthy I cant be bothered.
Maybe if it gets worse I will if I do I will post some pictures.

Here is what you need to do to check the ink tray:

Open the lid as if you were going to change cartridges. Does the carnage move freely? If not then you probably have a different problem.

On the right hand side (opposite the screen) there are two torx screws you can now see under where the lid was.

Remove these.

Remove the ridged plastic band that runs around the bottom right hand side of the printer.Start at the front lever the top left hand corner out with a small screwdriver. Whilst holding this out slide the front section to the right. Once this has unclipped pull the whole ribbed piece of plastic forward. Now the ribbed plastic band should come away.

Remove the side panel that the two screws held in place.

Now you can see into the printer.

Close lid and turn on and look and see what happens. If the carriage moves from side to side and hits the end stop on the open side of the printer but the small white gear under the ink tray does not move then it is jammed as mine was.

Turn off printer. Open lid again. move carriage out of way.
Put some disposable gloves on. Where the carriage stops on the right had side it pushes a small lever. Push this with one hand with the other hand gently move the ink catch tray back and forth.

Once it is moving ok pus back to back position.

Close lid power on. Hopefully that will sort it out?

Spent ages looking on the internet for a solution this thread was the closest I found, amongst all the HP junk telling me I had a paper jam. Hope this is of use to someone.

Try to turn it off, open cover and move carriage a little bit by hand; don't push too hard. For some time it'll get back to life.

Ok guys I was struggling with the same issue for HP 3520, so I opened the cartridge access door and press down on a small black piece of plastic (that holds the carriage in place) once you press it there will be a slight click sound and thenn move the carriage to the right hand side.
Now close the lead and click ok the clear message.

You should be ok.

This method worked for my model.
You must have the power turned on otherwise it won't move.

Open the cartridge access door, see where is the cartridge dock .. if its not stationed on the right hand side then try to move it with your hands back n forth

Close the door and it should work.

Lets assume it did not

The unplug the power cord from the back of the printer while its on.

Press and hold OK and CANCEL button at the same time

While holding them plug in the power cord, it should turn on and then release the buttons.

It should work

By the way also chek if there is any paper which is obstructing the carriage in moving freely

Sometimes the paper gets caught inside the printer all the way to the right (or left) of the print carriage. You will miss seeing it because the print carriage has moved the jamed paper to the right (or left) out of view. Carefully and manually move the print carriage to the opposite side and you might find small pieces of jammed paper there.

hi first of all open the front cover of the printer and try to move the carriage mannualy by your hand while the printer is on now if the carriage is moving freely look if you see any obstacle or any broken part in the carriage rod .... clean the carriage rod with a soft cloth and then remove the in cartridges and close the front cover now while the printer is power on press and hold # and * it will ask for the special key combo press 1 then 2 then 3 and now it will show you support menu use right arrow key and go to reset menu and press ok then go to semiful nvm reset and press ok wait for a min and then turn on the printer
wait for the printer to initialize now power on the printer and then wait for the message to insert the ink cartridge insert the ink and see if this works
if you still face the same error then it means its not a firmware error its a hardware malfunction problem and the device needs service you can also follow this document on the hp website and see if it works

Dear it's the carriage jam error. so it mean that your carriage is jam not paper. so open the printer where you insert the cartridge. check whether it is jam or what . cartridge carrier is jam kindly turn off the printer and try to move the cartridge head by hand very gently and if seems to be stuck than check for anything which abort him to move freely so than might be anything like dust or else. when you get success in moving the head put some machine lubricant on the rod on which head moves and check it ok.

Make sure you can move the print cartridge holder freely and that it isn't being blocked by anything inside the printer, also check if the cleaning station is in the right position, maybe it is locking the cartridges.

Try this:

Open door, disconnect power.
Move carriage to center by hand and ensure it IS latched.
Close door.
Reconnect power.
