Thank God our HR found the right man for the job

Hello Maxima79, check your messages please.

AFAIK you can input the special key combination to enter the configuration menu and change parameters or disable the heat section. Not sure if it can be disabled in all firmware versions. Look for the MPT control panel user guide for more info. You may also want to either plug the water prewash...

Some appliances use oscillating pumps ...valve system may be a bit different from GRI pumps though

This is weird. I presume you have run the correct ink amount and you used a densitometer. The round dot is a good choice, it offers predictable and controlled dotgain on press. Your screening is low enough to ensure good reproduction on paper with 97 percent measured at 95 patch as you say...

Please also mention what type of plates do you use. I've seen something similar when using processless plates... strange dot gain behaviour across the range due to platesetter overexposure or poor cleaning on press, or both.

Hi, put the machine in test pattern mode and run #4 for at least 30 seconds, then stop and cut. this is the sizing grid you can use to check all geometry, squareness, sizes a.s.o.

I've sent you a message

The machine detects the plate width i.e. x-size too short. Be careful when loading plates, the tolerance is small just 2 mm plus minus. Try loading the plate a very little bit more to the left or right. If the problem appeared suddenly and is permanent there may a hardware problem - centering...

It's not about calibration, but repair ... smth went bad during the laser diode replacements. - put the sonora plates aside and run all tests on positive plates (process by hand if needed) so you get proper contrast exposed images - run a grid test pattern to determine if H or V lines are...

what ctp do you have ?

Oh, here's the snail !

If that's evolution it looks more like inbreeding and this will eventually lead to the species demise. The (printing) habitat continues shrinking as we all see...

I put my money on the servo pack. Hook a dual channel scope on the motor connector, the waveform and phase may tell if it's an inverter problem or mechanical. You replaced the belt, did you check the AC Servo pack offset and gain ?

I assume the lines are horizontal, as you said "across the plate". In the past I've only seen series of 1 pixel dots across the plate, not solid lines, it turned out to be a damaged RB31. Your problem looks like an electrical failure has nothing to do with optics cleanliness IMHO as lines are...
