The plate cylinder (1-4#), the ink roller (6#), the swing ink feed roller (13#), and the drive roller (11#) must be adjusted after installation.
All other rollers in the ink transfer device do not have to be adjusted.
The ink fountain roller (14#) is adjusted together with the oscillating ink feed roller.
Note that all loosened screws are retightened after adjustment is complete.
Otherwise there is a danger of damage to the machine!
Before the ink is applied to the ink fountain, the paper must be coarsely adjusted. After all the rolls have been loaded, the coarse adjustment and ink fountain are inked and fine-tuned.
Loading the ink roller (6#)
The ink feed roller is loaded after all four of the plate rollers are loaded.
A smooth squeezing roller journal is introduced into the bearing that can be opened in the operating surface.
The threaded roller roller journal is introduced into the bearing of the transmission surface.
Required tools:
Two truncated fork wrenches SW24 in the random tool must be used for loading and unloading.
No force is applied to the drive train when loosening or tightening the nut of the oscillating roller.
The process is as follows:
Clamp the lock nut with a truncated fork wrench SW24. Tighten or loosen the other nut with a second truncated fork wrench SW24.
If you do not follow this method, there is a danger of damage to the machine!
The leveling roller (No. 15) generally does not have to be re-adjusted after loading. The dispensing roller can be disengaged by the handle of the drive surface during operation of the machine. This makes it easy to manually level the ink on the roll. The support of the leveling roller must be adjusted until the roller is fully raised and stationary.
If this is not the case, the stand must be adjusted. (Rotate the hex screw SW17 under the roller on the operating surface)
Adjustment by ink roller (1-4#) and ink roller (6#)
First, the pressure between the platen roller (1-3) and the ink roller (7, 8#) is roughly adjusted, and the pressure with the plate is adjusted. When the pressure of the plate roller and the plate is coarsely adjusted, the pad of the plate should be standard.
Coarse adjustment with the ink roller.
Adjust the platen roller by turning the eccentric bolts on the inside of both sides of the machine.
Tools used:
Fork wrench SW24
Adjustment process:
For this purpose, it is necessary to insert a 0.1 mm thick strip of paper between the rolls at about 10 CM on both sides of the ink roller. Adjust the ink roller until the two paper strips are evenly and smoothly pulled out.
Note: Oiled paper strips should be used when adjusting the new roller.
Coarse adjustment between the ink roller (6#) and the ink roller (3#).

Jog the machine on the way until you can see the plate slot.
Close the plate roller while the machine is stationary.
The punctual machine is about 20mm.
Then take off the plate roller.
Just click on the machine until you can see the ink on the drum. Adjust the plate roller with the width of the ink bar! However, the second ink bar is to be measured for this purpose because the first impact through the ink roller may be incorrect.
Adjustment criteria:
The width of the second ink bar (disengagement of the ink bar): the plate rollers 1.2 and 3 are 4 mm; the plate roller 4# is 3 mm.
In addition, it is also possible to roughly check the adjustment between the plate roller and the plate cylinder while the machine is running.
The guide roller 1.2.3# can be inspected by the probe 4 on the operating surface and the transmission surface. If these stencil rollers are regularly lifted during the operation of the machine, the pressure between them and the roller is indicated. is too big.
Need to re-adjust.
