The ink can be switched on with the ink switch (switch upwards). When so doing,
attention should be paid to the fact that in the event of incorrect installation ink can
spray out.

If the ink jet enters the gutter, the correct position of the jet in the gutter must be
checked and if necessary a fine adjustment must be done with the adjusting screws.
Insufficient or incorrect cleaning leads to jet jumping with repeated switching on and
off of the ink switch. Only if the cleaning has been carried out correctly will the ink jet
always enter the gutter at the same point. Further information on the adjustment of
the ink jet can be found in the chapter

Following the check of the above mentioned points the gutter can be closed and the
deflector unit swivelled downwards carefully by release of the toggle lever.
