When the printer is working for a long time, it may cause abnormal problems due to some internal settings. If such a problem occurs, Shenyang Oulans recommends a motherboard reset for the machine, so that the internal program and settings are returned. The factory state returns the machine to normal working condition. The specific steps are as follows:
1. When the motherboard is reset, be sure to power off the printer.
2. Open the printer cover and pull out the jumper on the battery side of the motherboard. After about 2-3 minutes, insert the jumper back into place.
3. Re-energize, if the machine will report the fault mentioned in the description after booting, it means that the reset is successful.
4. If no fault is reported, you need to reset it again by following the above steps.
