Solenoid lever down to unhook the both from each other.
6) Confirm that the gap between the pressure cam and Cam follower on the Pressure lever
assembly is 2.5 mm plus/minus 0.5mm.
7) If the gap is too narrow or too big, loosen the two set screws on the Pressure lever assembly.
8) Place a 3mm Allen wrench or 3mm thick plate between the Pressure cam and Cam follower, and
hook a thinner Allen wrench in the hole on the end of the Pressure shaft to rotate the shaft.

Results of Incorrect Adjustment
) If the gap is smaller than 2.5mm plus/minus 0.5mm, the printing pressure may become too weak
and print density problem may occur.
Also, the Pressure roller may land against the Drum in incorrect position and may cause ink
leakage from the Drum.
2) If the gap is too big, the Pressure roller may hit the Clamp plate of the Drum during printing and
damage the Clamp plate.
