Available for reset in service:
– Printers which can not be remotely reset
[with firmware version 02.xx and 03.xx termination ( example v3.01.02.00 / xx.xx.03.15)]
– Printers with some errors (do not allow the original firmware loading)

The only way to reset it is debug motherboard – downgrade firmware to a version wich can be reset (eg v3.00.01.19); operation which requires sending motherboard to us  in service to disassembly and connect the SPI / NAND memory on programmer.

Service time: 1-3 days (depending on the printer model)
