Tiskarna OKI B4350n - error 020

[hwnews konference]

Zdravim,
neresil jste nekdo nekdy tuhle chybu?

Hned po zapnuti nabehne ERROR020 a dal uz na nic nereaguje. Dle
servisniho manualu se jedna o ROM Hash Check Error 1. V tom samem
manualu se pise, ze po stisknuti ctyr tlacitek na panelu a zapnuti
tiskarny by melo najet maintenance menu:

The printer enters System Maintenance Menu when the power supply
switch is turned ON while the Menu/Item+/Value-/Cancel switches are
held down.

a dve z polozek jsou i:
Initializes Flash ROM forcedly.Every Flash ROM installed is subject to
initialization.
Initializes EEPROM.Special items, such as MAC Address, are not initialized

Bohuzel do toho menu ji nedostanu.

Kondenzatory ve zdroji jsem vymenil...nafoukle nebyly, ale vyssi ESR ano.

Asi bych se na ni vyprdnul, ale je k ni hromada spotrebaku vcetne valce.
