Prosetter 102 - problem, it prints like cardiogram

[chugo]

Hello everybody!

Have Prosetter 102, with mirror 633Hz

See attachment

As you see - print is like zigzag.

for information - we changed
1. Compressor
2. Two compressed hair filters

If the problem was in mirror or compressed air support then i must have chaotic print , am I right?
But we have zigzag print.

it prints like this about one time in twenty.

Please write what do you think?
