It can be divided into the reverse and the front. If you install it like this, it will be reversed:   You see there are keyboard plugs on both sides, so it must be installed like this: The location must be like this, otherwise the keyboard must not plug in.   After placing it, we install the screw and plug in the keyboard cables:   Then we install the cover:   Install the screws:   Then install it:   It’s installed：

Remove the screw:   Then remove the two screws above:   Then unplug the cable connected to the CE interface board:   Then you can take it off:   This is the transmission pump:   Then, take a look at how to dismantle the transfer pump, There are three screws here, which can be directly removed, and then the transfer pump will drop:   Then there’s a transmission pump:   Then this transmission pump we want to remove, we need to remove this screw:   And this screw is going to be removed:   Because the transfer pump is connected to the iron plate, we remove the two screws, then remove the iron plate, and the transfer pump can be taken out:   Look at how the solenoid coil is removed, pull it back, it will fall off, and then the coil can be removed:   If you want to remove the solenoid valve, first remove the four screws, and then we can remove the solenoid valve:   Then this is the pressure sensor : If you are not a professional, it is not recommended to remove it, because if it is not installed properly, or if the pressure sensor drips ink, it will easily break down. Even if we remove it now and then install it, it may also report a warning on pressure.   If you want to remove the pressure sensor, you need to remove it first:   Then remove the four screws:   After removing the

We click on the password in the main interface: Then enter the advanced password, each day the advanced password is different, after the input is complete, and then return to the main interface.   Then we click Tool:   Then, click Service:   Then click MI Engineer:   Then, click Factory Settings:   Our current model is MB175 ink: If we want to change the solvent we have to change the ink, because the ink and solvent are one-to-one correspondence, MB175 corresponds to A188.   We now choose FB660: FB660, its corresponding model is A661.   Then, after selecting it, we click NEXT:   Click yes：   Then we click the key in the middle: Then,power off the machine and restart.   Then we click on one of the keys:   Then the models have now become the A661 and FB660: The changed ink model and the solvent model correspond one-to-one, and it will automatically come out.

Take a look at how the power supply is disassembled, First remove the screws around the lid, and then remove the lid:   When the back cover is removed, all we see is the power supply:   To remove the motherboard, we’re going to take the two screws off:   Then we take it out, this power supply includes fans, and we can take them off together: Now as soon as you pull the wires above it, the power supply is removed.     Let’s see how the motherboard is removed, First unplug all the wires connected to the motherboard:   To remove the motherboard, we will loosen these two screws:   Then remove the two screws:   Pull out the lines inside, and the lines below the motherboard, and we can pull the line below the motherboard from the front, and after unplugging, we can take the motherboard out:   The same is true for the installation of the motherboard, first install the two screws:   Then install the two screws on the side: Then plug in the wires on the motherboard and the motherboard is installed.
