Now, the scan plate can be opened completely.
-
Search for screws, one in both corners and unscrew them.

The print board is connected with 7 screws and 3 wires. These screws are situated on the right side of the gray board in the middle.

Slide the first motherboard out of its case and unscrew the one that is connected to the print board.

The blue and red wires are connected to an electro motor and the backside of the printer. The wires are also wrapped around a cylinder. (Can be seen in pictures 2 and 3.)
-
Follow the wires along the backside of the printer and loosen them everywhere where they are wrapped around the backside.
-
The cylinder is connected by snap fit systems. After disconnecting the cylinder, the wires are loose.

Taking out the next gear is roughly the same as in the previous step.

A reasonably competent DIYer can follow this usefully. Many thanks
A very good tutorial ! Thank you. My print heads are completely out of adjustment and I can no longer align them with the procedure in the user manual. Any idea ? I’m about throw it away :(
Is the flat washer on the table on STEP 18 the same as the one on the printer in step 19? (STEP 19). Where does this go please?
Is there ANYWHERE I can find the blueprint schematic for this model and it’s parts? There is spring I can’t locate where it goes.
These instructions are not compete.
Step4: You can’t just remove two screws and “lift off” the scan plate. Where are the instuctions/pics on how to detach the two ribbon cables which connect the scan plate to the main unit? They aren’t even mentioned yet can wreck the scan plate if you don’t know how to safely disconnect them first.
And WHAT VALVE???? There is no valve.
