AX060396 is the new part no.

My understanding was that the polygon mirror motor causes the SC202, but it's the BICU that causes the blank display, hence why both are replaced at the same time. I can't see that a faulty polygon mirror motor would give you the display problem

A faulty driver IC on the polygon motor PCB can either blow a fuse-resistor on the BICU pcb or just somewhat messing with the BICU power circuit - in both cases - as a side effect - the panel remains dark. From my experience in 4 of 5 cases that little fuse on the BICU is defective.

Re: MPC 2800 power supply to a mpc3300. .compatible? DO23 DO25

well i got everything running again.
turned out to be the sc202 error wth both the polymotor and BICU needing replacing.
i culd not read dead display wth flashlite and IT guy gave me the wrong ip address
but after messing around on customer laptop i found it and got the sc202 code in WIM.
THNS TO ALL.
does the new polymotor have a different part number?
thnx

Props go to "Polarbear" on this. I saved a copy of his findings some time ago, for my future reference:

I fix BICU board in same way.
I made a schematic diagram of BICU. This helps to understand how +24V redistribute through BICU board and what will happen if it short to ground (SC202).

fix the PCB (search forum)?
i did a search mpc2800 bicu and found lots on dreaded sc202 code and what looks like my issue..
didnt see reference for fix the brd?
was this for repairing bicu or plygon motor brd?
does anyone know what goes on polgon motor?
thnx

IO f IT isn't available and you cannot check the IP address in the print driver on a computer, follow Sandmanmac's suggestion and shine your flashlight across the display.

thnx
im familiar wth what using the flashlite from fixing laptops wth bad backlight inverters or invert brds..
i have a call in to IT guy who should get back to me b4 i arrive on site.
my guess is the polymotor and or BICU brd.
i dont have more than 10 of these out there so this is my 1st time seeing this issue.
kinda wish i had researched this b4 taking the look yesterday.
i knew the lcd displays had issues and just figured it wld be a quick swap and fix..

thnx
i cldnt get the ip address as the IT guy has everything on lockdown..Outside and hard to reach.

cant access ports on printer configuration.

honestly i never logged on a copier in WIM wth a sc code.till now wth a mpc2050 i have blowing random sc565 code.
now i see it Call Service Center:SC565..

with regards to bicu brd and poly motor,,
can i swap the mpc3300 parts into a mpc2800?
thnx

Re: MPC 2800 power supply to a mpc3300. .compatible? DO23 DO25

All this SC 20x related stuff is just valid if the screen backlight is missing but LCD still working (check with a lamp - it'll be hard to recognize):

Unplug the polygon motor, trurn off the machine - if the panel comes back the BICU isn't fried -> just replace the polygon motor and you're good to go.

If the panel doesn't comeback -> the BICU is probably fried as well (happens in most cases) - you can either try and fix the PCB (search forum) or swap the BICU and polygon motor. As statet before: Never use a healthy BICU with a faulty polygon motor.

If you can access the machine with WIM, see if there is a polygon motor error.

Re: MPC 2800 power supply to a mpc3300. .compatible? DO23 DO25

Are you sure your issue isn't the very popular SC202 that you can see by shining a bright light in the display, where the Polygon motor takes out the BICU?
If so, they must be replaced as a set, or the motor will short out the BICU again.
Luckily I've never actually run across it.

What, never???? I have had this fault so many times.
As Sandmanmac says, if this is SC202 (if you can access the WIM you'll be able to confirm this) then you must replace the polygon mirror motor and BICU as a set, if you just replace the BICU then you'll fry a second one if the faulty motor is still there

hi
i just went to a mpc2800 i placed 2 weeks ago where the touch screen is dead,or black.
