Lines appearing from the CtP Machine

[Qube]

Hi

I need some information on a problem I am having with my CtP PlateRite 8000II:

There are very faint broken lines (almost looks like perf lines) running across the plates. It is not visible on the plate, but once inked up you can see it. I have tried to delete it with dilution fluid and it will not come off. They are on all the plates CMYK at about 1%. We are a bureau and supply all size plates to printers and this is happening on all the different size thermal plates. The lines run horizontally on the plates

I have attached a scan.

Hi Qube

Ask engg to check with Focus of the lens.

Hi Arkay

Thanks he will look at that.

I had some stray lines appearing intermittently...we swapped the cable and then the interface and they cleared up...may be an issue of data transfer.

May be RB31 board broken! prat No.U1154007-01

Our 4300 does this as well. Usually after 30-40 plates in a row. It seems to be something overheating, tech thinks it's the "main" board.
A 10-15 minute powered off rest fixes it for a while.

Transistors on the circuit board and over heat aging lead to such......

Hi,

Have you try print a solid or 50% tone from the CTP self test (not from the RIP)?
If still have lines, possible something wrong at CTP.

Dear Qube,

My name is Jessy, im writing you from Kenya . I hope this email finds you well, I come across your issue of lines on the ctp plates, im experiencing the same issue with my machine. I have gotten 3 different Engineers to look at it but no results. Please may i share with you a picture of my plate with lines. I dont want to purchase the PIF card or interface cable and the problem might be RB31 Board. Your quick response is highly appreciated. you can contact me via this email: [email protected]

Regards<

Jessy.

Check the screw drive, for the laser. Check the away side. Mine was a bad O-Ring
