Press clear, auto , clear auto alternate until it turns off, then enter the # 14 and the machine will reboot. Our machine does not say exposure it says Auto....so this may be a little clearer...That should solve the problem.

SOURCE: trouble code

NOTE: Some Status codes will not clear even though the problem has been fixed. Status codes that will not clear must be manually reset using the 'Fault Reset 14 Procedure'.

  1. Locate the [C] (Clear) button on the Control Panel, at the far right.
  2. Locate the Image Quality button, below the Auto on the Control Panel, toward the left side.
  3. Press the buttons in the following sequence within 4 seconds. Press [C] (Clear), press [Image Quality], press [C] (Clear) again, press [Image Quality] again.
  4. The error code should disappear. If the Status code does not clear, repeat step 3 until the status code clears; but no more than five times.
  5. Use the [10] and [1] buttons to enter 14 on the Display Screen, as if you were to make 14 copies.
  6. Press the [Start] button. The machine should be ready to use.
  7. Make a copy, to check that the machine is working properly.

SOURCE: H4 error message

Heat roller low detection error. The thermistor and lamp need to be checked. It could need a new fuser assembly.

SOURCE: H4 error on Sharp SF 7370

Low fuser temperature.....probably the heater lamp, possibly the fuse. You'll have a hard time getting either of these...and I wouldn't recommend spending any money on it anyway. I suggest it might be time to retire the old beast. Only a few hundred dollars these days to get a little Digital copier

Call for service: h4-00


H4-00 means thst the copier isn't warming up quickly enough. Try this code to reset it. Press the following buttons in this order: #, interupt, C, interupt, 1, 4 . machine will say sim 14 trouble clear are you sure. Press the OK button. This should reboot the copier. Most likely the machine is in need of a heater lamp in the fuser unit.
