My HP 6968 inkjet printer has error 0x6100004a and is stating that there was a paper . There is no paper jam, but now the ink cartridges are stuck on the far right hand side, and I can`t move it manually. I checked all the ink cartridges and they are seated properly. I changed the black and yellow cartridges last week. We tried to print something on Friday, and that`s when the printer said there was a paper jam. Has anyone seen or had this problem?
