Problems with Dolev4press

[alvoeiro]

Hi everyone,

I am newer in this forum.
I read many threads and i'm not found any about my problem.

I had this problem any time i print on my dolev (see the photo below)

Has anyone had the same problem?
How can I solve?

Thank you all,
greetings

Hello Alvoeiro,

There is a problem with spinner encoder. Weak diode, dirt disk, misalignment. Ask for professional support on local dealer. You can try a plot at lower spinner speed.

How i configure the machine to plot at low speed?

Go to NVM, look for res tables. Next to resolution in DPCM is spinner speed in RPM. Lower the RPM number, press Save all (with appropriate function key). Then you have to recalibrate the machine strating laser intensity and then excurve. If this helps, you will work with lower production since lower spinner speeds means thatit will make image slower.
But I think that you have some other problem, probably in electronics or even software. This is too regular to happen as a consequence of dirt.

Hi,

How i recalibrate the machine?

if it is to be dirty, which may be? which zone should I clean the machine?

Recalibration is explained in users manual. You need film densitometer for that. Find the right density and then correct ex-curve.

Dirt: don't touch optics. Try to clean all contacts like cards in dolev and cable connectors. Long shot but who knows. If it is optics, it is cheaper to call service specialist.

In most cases only after printing is half that it begins to "drag".

But I'll do what I say and try again.
Thanks for the tip, I'm communicating.

Hello,

I just thoroughly clean all circuit boards including the Dolev also RIP and everything stays the same.

A few years ago I had a problem, can not remember if the same, and the only solution was to replace the TSP board RIP. I will face the same problem?

In Portugal it is difficult to get technical assistance for these machines.
Is there any site / store in europe where you can buy parts for the Dolev?

.......

Could be temperature related. Try to put a small fan to blow direct on TSP board. Also check in Dolev the fan condition. On lower left side on back.

I'll try to do it now ...
