I understand you have an Officejet 4622 that is telling you it has a carriage jam. I'm sorry to hear this has been happening, but I will certainly do my best to help you out!
Because you can move the carriage manually, I'm hoping this Carriage Jam document will be able to assist you in clearing that error. Please also ensure your printer is plugged directly to a wall outlet to make sure it has all the power it needs to function properly.
Hope this helps, have a great day!!
