General Precautions
Main Frame Screws
There are paint-locked screws across the top of the machine (under the top cover). These screws are
positioned and adjusted at the factory. Never loosen or attempt to adjust these screws.
Right Plate Screws
You can see the heads of four paint-locked screws around the top of the maintenance unit. These screws
hold a re-enforcement plate. Never loosen or remove any of these screws.
Maintenance Unit Base Screws
The maintenance unit base plate supports the maintenance unit. These screws hold the base plate under
the maintenance unit, which must always remain in the same position below the carriage print heads.
