Xerox 4112 fuse blowing in F10 position on IOT PWb started with error code 010-315

Your fuser is not coming up to temperature. Power off the printer. Remove the fuser and check for any bent pins or breaks on the hot roller. If all looks all right, reinstall fuser and power up the printer. If the error returns. Your fuser most likely need replaced. I hope it's just that. Replacing the Main Control Unit Printed Wiring Board (MCU PWB) or the Main Low Voltage Power Supply (LVPS) are not cheap! Then again, neither is the fuser! But not as much as the other two!

9-363 is either the developer housing rotary system did not reach home position. or you need to check fuses in Rotary PWB. It's more a job for a service centre.

If you wish to check the fuses yourself

rotary pwb. Its behind the IOT pwb. Basically at the top left hand corner as you look at the rear of the machine. It is the 2 fuses that are harder to get at, may as well change all 3 whilst your there. The rating for the fuse is written on them.

If it's the developer motor taking it off and back can fix it from seizing and it may operate normally.

The RAP does not lead you to the connector unless you trace the wiring in the BSD. This connector is located on an air duct on the bottom right hand corner of the IOT Drive PWB and acts as a double plug to connect on one side to the connector of the IBT Cleaner Blade home position sensor and the other side to a connector that leads to the IOT Drive PWB. After firmly plugging in the connector, the fault code went away. call 98413 40555

change the IOT back side clutch that appear behind the back side of machine which rotates the ITO (black roller in main path of paper) just try with cleaing clutch other wise change it
and remove that IOT back side gear which rotate IOT black roller without that gear u can print

i solve my problem with this methods

fuser nip fail
replace the IOT DRIVE pwb in fuser section
hope this work for you

Yes Its on the rotary pwb. Its behind the IOT pwb. Basically at the top left hand corner as you look at the rear of the machine. I think it is a 3 amp slow blow but cant quite remember. Definately slow blow though. Sometimes if you meter them they can read ok but as soon as a load is passed through them the fuse cant hold the charge and fails. It is the 2 fuses that are harder to get at, may as well change all 3 whilst your there. The rating for the fuse is written on them. Worst case is the developer motor has seized, taking it off an putting it back on again usually remedies this, but its a bit more awkward to get to. Fuses first

This code refers to a halftone pwb fail, if fault occurs when coming out if powesave I would suspect a lvps fault, other things that have can cause this error include front door interlock, vsel pwb, fuse 4 on distibution pwb, open circuit on 5v to ROS, faulty ribbon cable from IOT CPU to halftone PWB.

I would try first to reseat the PJ on the IOT CPU mainly p397 and p398 and pj403 ribbon cable, also dont overlook the front door switch as this will cause low voltage problems.

My apology. I recently left my job. I no longer have access to xerox documentation and the codes. And I do not want to make a guess and lead you down the wrong path to a solution.
If you haven't resolved your problem, I would suggest reposting it on the main board here and allow someone else to provide your answer.

To reset the errorplease press in the following order:

CLR - AUTO - CLR - AUTO
(this puts the unit in tech mode).

Enter 14 (as if asking for 14 copies)

Press "PRINT"

Your unit should reset itself and start working

It is a fuser error.

Try resetting. To reset a Rank A error follow these steps:

1. Turn OFF the Main Power Switch.
2. Turn Main Power Switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the Main Power Switch, turn it on again more than 10 seconds after and check if the machine starts correctly.
If the error recurrs then do the following:
1 Check the Fusing Unit for correct installation (whether it is secured in position).
2 Check the Fusing Unit, PWB-M and PU1 for proper connection and correct or change as necessary.
3 Change Fusing Unit
4 Change PWB-M
5 Change PU1
