Sharp copier AR5516 not working. Error code E 7 kindly help.

H4 indicates "low temperature", possibly caused by a failure of the heater lamp or fuser. Sometimes this error is shown without an actual damage when the power cord is pulled without shutting down the copier first.

To cancel the error code, press [CLEAR], [AUTO], [CLEAR], [AUTO] in rapid succession. The display should go blank. Next, select 14 (clear low temperature code), press [START]. Finally, switch off and on the machine.

If there was no actual damage (i.e. power cord pulled), the machine should be OK again. If the error persists, immediately or after short time of operation, you will need to contact Sharp technical service for repair.

H2 signal is thermistor open
check the harness and the connector between the thermistor and the PWB use TC 14 to clear the self diagnostic display.

A U2-00 is an internal error code from the main processing board's EEPROM (the chip that stores your configuration choices, the copier's serial number, etc.) It can be a faulty EEPROM but most likely the copier took a power hit/glitch and the fault needs to be reset.

To clear the fault make sure the copier is in Copy mode, then press the 'P' key, then the 'Interrupt' key, then the Clear (C) key, then the 'Interrupt' key. This will enter the machine into simulation mode.

Now enter the number 16 and press start. The machine may also ask you to confirm your choice or you may have an 'execute' key on the LCD screen.

Once the fault has been cleared the machine should reboot. If it doesn't, press the 'CA' (clear all) button and the machine should reboot.

If the U2 code persists, you need to call a repair technician to facilitate repairs.
