Xerox Workcentre XE80 is giving me a J2 signal with middle light flashing. I've replaced the toner & drum. Still gives me code.

Most likely the "remanufactured" cartridge does not have the counter reset flag in the proper position or is missing completely. Just reset the counter via the service mode by pressing these keys in sequence and as quickly as possible (within 4 seconds).
Press Clear, then exposure mode (far left key) the clear then exposure mode again. So in short form C, Far Left, C, Far Left. If done properly the display will go blank. Now key in 24 as if you wanted to make 24 copies. Now press the print button. Now enter 7 then press print again. You should now see flashing 000.
Press C a few times to exit and the drum light/J2 should now be gone.
Good Luck and Thank You for using Fixya.

You can get the spec sheet and the user's guide as PDFs here:

The spec sheet has the toner cartridge and drum cartridge part numbers (listed as Supplies)

Toner Cartridge 6R914;
Drum Cartridge 13R551

When copier has printed about 18,000 pages the J2 drum cartridge light will come on. The unit will print about another 1,000 pages before the unit stops working until the drum cartridge is replaced.

I hope this helps.

1. turn off XD125f
2. Turn on
3. within 4 seconds press, clear, auto, clear, auto. LED Should go blank,
if not try again
4. use copy quantity keys to enter 24, then push start
5. Again use copy quantity keys to enter 7, then push start
6. turn off
when you restart the cartridge count will be set to zero

I have done this twice and never replaced the drum cartridge.

With "J2" flashing, press:
1. "CLEAR" button
2. "AUTO" button, then again
3. "CLEAR" button
4. "AUTO" button

Do it fairly quickly. If it's done quickly enough the display goes off. When it does:
5. enter "2" and "4" (see "24" on display)
6. Press "START/COPY"
7. Press "7"
8. Press "START/COPY"
DONE

If display doesn't go off repeat steps 1 to 4 but faster, until display is off.

Hello sir; Just replace drum cartridge, it will take care your problem. GOOD LUCK!

J2 is the drum cartridge, or some people call it print cartridge has reached the end of its life.
J1 is the toner cartridge, J2 is the drum.

J2 means the drum cartridge needs replaced.
Its next to the toner.

J2 means the life of the drum has expired.
If replacing the drum does not fix it let me know.
J2 means the drum has met it's 18,000 page life.

J messages on Xerox machines always refer to toner or drum.Is the toner out , you could give it a shake (might be a good idea to go outside!) Sometimes it will run out without displaying a message(Pyramid of dots for out of toner) Drum end of life usually comes up with a crossed circle or similar .If all OK you could have a blocked toner supply auger or lumps caused by storing toner in sunlight, both would require the toner system being vacuumed out.
