Introduction
This is a troubleshooting guide on how to replace a Print engine board (PCB).
Scope
This applies to FP-125/Sprint printers only.
Symptoms
Printer is looping in Auto System Maintenance. Printer stuck in reset service
counter (only in more severe cases)
Possible causes
Static electricity blowing out F1 or F2 fuse on print engine board.
Step1.
Before starting power down the printer and remove all cords. You will need a
Phillips screw driver and a Antistatic wrist strap to prevent any static electricity
from damaging the circuit boards.
We will start in the back, and remove the clutch/table cover (big box in the back).
This cover will have 7 Phillip screws holding it down. 3 on top and 2 on each side.

Once the cover has been removed your printer should look like this.
Step 2.
Next we need to remove the lid of the printer. Inside the printer you will see the
strut the holds the lid open. The strut is held by a small E clip. You will need needle
nose pliers or a small knife to remove this piece. When the E clip is removed you will
be able to slide the strut out. You will need to remove the 7 screws holding the lid
down. One will be located right above the USB port.

Once the 8 screws are removed you will be able to pull up the board cover. Be very
careful when removing the cover you don’t want to damage any cables.
Once the cover is removed your printer should look like this.
5. With the cover removed we will begin removing the Print engine board (PCB).
First we must unplug all cables connected to the PCB. Before handling any of the
boards you must first us a AntiStatic wrist strap to prevent any static electricity
from damaging the new board. Carefully remove all the cables from the board. The
white ribbon cables should be taped down so you will have to remove the tape first.
Be very careful you don’t damage any of the cables. Once the cables are removed
you can start removing the 4 screws located on each corner of the board.

When the damaged board is removed replace with the new one and plug in all the
cables back. Each ribbon cable is labeled and the board has the same labels printed
on them as well. Make sure all cables are plug in before powering up the printer.
When the board is back in you can start putting the printer back together. When you
power up the printer should do an Auto System Maintenance during the start up
process.
