HI, My HP Designjet shows ERROR 21:13 and restart printer, Each time i restart the same code comes and nothings to move,Please I need help what is it for or someone have SERVICE MANUAL for T 1100, I will be grate full. THANKS.
When the T1100 first came out there was a problem with PHs and the SS failing because they were spitting too much ink into the SS. They fixed this with a firmware up grade. If you replace the SS I would also upgrade the Firmware.
