Possible reasons for errors:
See figures on the next page.
If a dot from a certain printing pin is missing regularly, the reason might be one of the following:
1.
Defective magnet (The self-diagnostic system will find this one first).
2.
Broken short pivot arm.
3.
The long pivot arm cannot move because of dirt.
4.
The printing pin is stuck because of dirt, causing the short pivot arm to miss the long
pivot
arm.
5.
Errors in the magnet rack board.
If dots from several printing pins are missing now and then, the reason might be one of the following:
1.
The sponge list is pushing too hard on the long pivot arm.
2.
The gap between the two pivot arms is too large.
3.
The support list has become sticky on the side against the long pivot arms, and the long
pivot arm does not move properly.
4.
The sponge list on the short pivot arm is so worn/compressed that it will not provide
enough tension on the pivot arm.
If there are too many dots on the paper, the reason might be one of the following:
1.
The sponge list is not pressing hard enough against the long pivot arm.
2.
The gap between the two pivot arms is too small.
3.
The magnet poles have become sticky, and this causes the pivot arms to stick to the
magnet.
4.
The long pivot arm does not move properly.
Control:
To be sure that you have found the right mechanism after troubleshooting, you can do the following
test: Carefully pull the suspected long pivot arm against the magnet with your finger.
Note! Please be careful to avoid getting in contact (e.g. clothes, hair, beard, jewelry or any part of the
body) with any other moving parts of the Printer to prevent injuries!
At the same time, run a test print. The mechanism with the finger on, will make a row of dots across
the sheet until you take the finger away. By doing this you can see if this row of dots is situated on the
same place (and same side!) on the sheet as the error is.
Observe that the same printing mechanism (magnet, long pivot arm, short pivot arm and printing pin)
makes all the dots in a row across the page.
