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.

No display blank screen


hi sir. the problem is the flex wire of the display on the handset unit and this is common. you have 2 solutions. first change for a new the handset unit. or open the handset, remove the main board, separate slowly the display screen from the main unit. whit a hot air gun, give some hot to the white flex on the main board side(not too much or you can destroy that). and tighten a little with your fingers on the flex and the main board. This should paste the flex.

Failure in either of the following can cause no video output.
  1. Display Panel
  2. Y Drive Board
  3. Y SUS Board
  4. Z SUS board
  5. X Drive Boards
  6. Tape Carrier Package (TCP)
  7. Main Board
Try these if you have electronics background :
Note: Touch your fingers repeatedly to a ground connection point or unpainted metal in the product before proceeding.
  1. Unplug the unit.
  2. Remove the back cover by removing the screws holding it.
  3. Disconnect the LVDS cable from the power supply or from the main board. LVDS cable runs from the right bottom of the power supply to the upper left of the main board. Power supply is located at the upper center of the unit and the main board is at the right bottom of the unit.
  4. Plug the unit back and turn it on or the unit turns on automatically.
  5. Look for the Control Board. It is located right at the center of the unit below the power supply. It has a LED on it.
  6. On the Control Board at the right bottom of the MCM chip, the big chip right at the center of the board, you can see two test points. Short across the two test points.
  7. If there appears a picture of cycling colors and patterns, the Y-SUS, Y-Drive, Z-SUS, Power Supply, X-Boards, TCPs and Panel are all OK. The Main Board or the LVDS cable is defective.
  8. Check LVDS cable continuity.
  9. Replace Main Board if LVDS cable is good.
  10. If no picture of cycling colors appeared on step 6, some adjustment is off or some portion of the signal is missing.
  11. Check fuses or continuity of voltage supply lines going to the X Board/s, Y SUS and Y drive Boards and Z SUS Board.
  12. Replace blown fuses, connect broken lines, and resolder loose solders.
  13. If no apparent damage is found, ask for a qualified or experienced technician's service. Massive and sophisticated tests and voltage readings are required and proper tools are needed such as oscilloscope to find which signal is missing. The parts to be tested are prone to handling damage and requires proper handling and testing.

Error code on kyocera fs-3800 printer


E1: xxxxxxxx = Main motor error
Either the motor aint turning or it is being stopped from turning...Usally drum or developer units cant turn, or main motor or control board stuffed...

below is stuff from service manual and ....my comments

Suggested causes
The main motor is overloaded. Overcurrent in the main motor circuitry due to an excessive torque....... Check Drum, developer unit, toner cartridge and process units ensuring free movement
• 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). .........secure replace cable
• Defective harness between engine relay board
(KP-760) and main motor.
