problem with fuji frontier 375 replenishment mixing, thank you for help

[tom008]

My frontier 375 got in trouble again 1 week ago. I had the problem first with P2(bleach-fixer tank) heater. The heater stopped heating process without reaching to setup temperature because the inner pipe of the heater has accumulated a layer of chemical. I then clean up the inner pipe and the heater back to work again.  Before I cleaned the inner pipe of P2 heater I didn't empty the chemical in  P2 tank,  instead I just disconnected the heater with the in and out  chemical pipe. Some chemical running out of tank. When I clean up everything and turn on the machine again, the printer detected the short of chemical and start to mixing. However the mixing process stopped in half and never start it again. I then tried to manually mixing the chemical by pressing 5 time menu key -install- mixing, it showed "E2606 Replenish Sec" on the printer little screen. I took off the M740 mixing motor and test it with a car battery, it runs fine. Now I can not turn off the printer from the FMPC(computer), the computer says  "Please wait, Mixing".  please anyone know what is going on , thanks a lot.

E-2606 means drive motor for opening replenisher cartridge abnormal. Replenisher cartridge section malfunction.This error can cause :
1. Connection error or disconnection between replenishment cartridge opening motor(M740) and PAC3 on PAC20 circuit board.
2. Replenishment cartridge opening motor(M740) malfunction
3. Connection error or disconnection between replenishment cartridge box upper/lower sensor(D742/D743) and CTP17 on CTP20 circuit board.
4. Replenishment cartridge box upper/lower sensor(D742/D743) malfunction.
5. Connection error or disconnection between replenishment cartridge box door detecting interlock switch(D744) and PAC22 on PAC20 circuit board.
6. Replenishment cartridge box door detecting interlock switch(D744) malfunction.
7. PAC20 circuit board malfunction.
8. CTP20 circuit board malfunction.

Check all that. Go to input - output check menu to test sensors and motor, use multimeter to check voltages. Can follow troubleshooter 3.3.13 ( Replenishment Cartridge Box Malfunction ) on Fuji 375 service manual.
