We are using a HP Laserjet 4 printer that started going crazy on Friday. Someone tried to print a document that called for A4 paper and it gave the error to load A4. After that it keeps saying "PC LOAD LETTER". All of the jobs that were to be printed were cancelled. The only paper that it prints is letter(8 1/2 x 11 1/2). There is already paper but it will not reset its memory. I have tried their website and they gave the solution for the error but it will not work. They want me to go offline and reset it but it never goes online and I can't do much of anything. If anyone has any ideas I would really appreciate it. Thanks!!
