Bizhub 25 Checkout error :18

[compelecttech76@gmail.com]

Hello all,

I have a bizhub 25 with a Checkout error 18 fuser error
This is what the service manual suggests.

18: Fuser Error
Causes:
(The number indicates the detailed error code)
0 The fuser did not become to the main motor driving temperature in 50 seconds after printing started.
1 The fuser did not become to the paper pick-up temperature in 50 seconds after printing started.
2 The fuser did not become to the main motor driving temperature in 30 seconds after warming up
started.
3 The fuser did not become to the warm-up finishing temperature in 30 seconds after the motor started
driving.
4 A temperature of 250°C or higher is detected in a mode other than sleep mode.
5 The fuser does not warm after fuser error is solved and the power is turned OFF/ON.
6 A low temperature of 10°C is detected in 10 seconds after printing started.
7 A temperature of 190°C is detected in ready mode after printing finished.
Suggested corrective action:
1. Turn on the power again, and verify the fuser warms up. If it does not, see step 4.
2. Check the contact between Fusing thermistor and Connect A PCB(P89).
3. Check the contact between Connect A PCB (P80C) and the main board.
4. Replace the Fuser.
5. After replacing the Fuser, verify the fuser warms up when the power is on.
6. Replace the main control PCB.

I've done it all still get the same error.

Any suggestions will be much appreciated

i have seen ICP fuses on the prcb shared with fuser and IU, you get the error on boot i assume? try swapping the IU, could be false error triggered.
also have you tried firmware?

are you an authorized dealer? ive had unrecoverable errors on bh25s and c35s and SSD has replaced the machines with 3110s (refurbished) but got rids of the sore thumb.
i would check wall voltage, neutral to ground.
only because you didnt say so, did you try:
This mode clears the service call. Clear the warning when the trouble is settled. If fuser warming up
error is settled, turn the machine OFF and ON following this operation.
1. Press <Setting>, <*>, <4>, <5>.
2. Press [Yes].

Not a power issue, tried a different Bizhub 25 and worked fine.

Also did the *45 reset and still same error
