Blocked 1400 carriage

My Epson 1400 developed an error last night: when I power it up, when carriage tries to move to se the printer up, I can hear buzzing noise from the printer, like it would like to move the carriage, but can’t, and then paper and ink lights start to flash. I checked the interior of the printer, but I can’t find what is blocking the carriage movement. Does anyone successfully unblocked the 1400 carriage?
