Re: main board where can I get it

Search brother homepage for a service dealer near your home.

You will find out that the spare part will cost nearly the same as a complete new mfc!

Tip: Search eBay for a 2nd hand mfc 5840 with rotten printhead.

detection signal
error 2
221-001: Y
221-002: M
221-003: C
221-004: K
Main scan length detection is
not properly completed ten
consecutive times.
The front (for C&M) or rear (for
K&Y) laser synchronizing
detector boards are used for
the main scan length
detection, which automatically
corrects the main-scan
• Damaged or
disconnected cable
between front (C&M)
or rear (K&Y) laser
detector board and
the LD unit
• Incorrect installation
of front (C&M) or rear
(K&Y) synchronizing
detector board (the
beam does not target
the photo detector.)
• Defective front (C&M)
or rear (K&Y)
detector board
• Defective LD unit
After doing any of the following, print ten
jobs or more to see if the same SC code
is displayed:
1. Turn the main switch off and on.
2. Check or replace the cable
connecting front (for C&M) or rear (for
K&Y) synchronizing detector board
and the LD unit.
3. Check or reinstall the front (for C&M)
or rear (for K&Y) synchronizing
detector board.
4. Replace the front (for C&M) or rear
(for K&Y) synchronizing detector
5. Replace the laser optics housing unit.
6. Replace the BCU.
If a synch. detector board cannot be
replaced, do the following as a
temporary measure:
• Disable main scan length detection

Means that the laser synchronization signal cannot be detected by the main scan detector board.
Possible causes:

Laser synchronization detector board out of position or is defective.
BiCU board is defective.

Unfortunately,unit needs service.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

• Connector insertion error........check developer plug is secure (left top near toner cart little plug)
• Defective gate array U204 on the engine
board (KP-864). .......replace board
• Defective harness between engine board and
engine relay board (KP-760). replace cable
• Defective harness between engine relay board
(KP-760) and main motor.
