Sanskar Patel, Try to clean and reset your printer to get rid of the Error code: 0x9A/carriage fault.
Open up the printer check for scraps of paper, lint or foreign objects,staple, etc. Make sure carriage moves manually, or moves on its own when raising lid. If moving freely, continue cleaning with compressed air blowing out inside printer compartment while checking both sides are clear, wipe down the encoder strip with a soft cloth and a few drops of alcohol, it is a clear plastic strip running the width of the printer, that sits just slightly above and behind the carriage. Now reset the machine, detach printer from outlet, wait 5 minutes then press and hold power button a minute or two, while still holding power on button plug printer in and continue holding button for another minute after plugged in, release button.
