Yes it is. And different cassettes/films could have different values. That's one of user available params at OCP. I think brent is not familiar with Avantra.

Laser Carriage movement is the Slow Scan, so... what's the Fast Scan? LOL

In our conversation Please use Slow scan and Fast scan directions instead of length and width. I hope you count 10 rectangulars in both directions in your measurements

You almost kill my brain with that question! :) In the Cassette window at the Control Panel Avantra 25 has maximum imageable area 17.7 (450mm) by 25" (635mm) for 457 mm width film. So max area should be 7 mm less than actual width of the film roll for any roll size.

Beginning Of Line - BOL in that case does not work. Something wrong with a scale value. Check your Avantra first - internal exposure test has 100% and 50% rectangles with 0.5"X1.0" size, so you can calculate the size of whole test pattern.

USB to connect RIP -> DPM ??? May be Differential SCSI or am I too far from today? Do you use a BlueBox interface?

1. It's a scalling factor. You can't reach it through Control Panel menu. AvDiag/UniDiag software + cable + service experience = final solution 2. It's BOL shift. See lines 2 and 3 above

Do you use AGFA Developer and Finisher (gum)? How long you keep plates before putting them on the Press? Can you make some zoomed photo of image elements and publish in here? That's not an easy task to find the culprit with such a lack of information from you.

http://www.mitsubishiimaging.com/silver-digiPlate.htm Just to start the search AGFA had SetPrint materials as well, but I am not sure they still keep these plates in production.

You are right. If Avantra exposure test has no extra lines, that means something happened on the way of data transmission from RIP to Avantra. You have 50/50 issue: 1. Avantra DEC board, APIS part, one of three microchip SN75ALS193N data receivers has a kind of age degradation. As a result of...

Ask AB Dick for SoftWare, if your customer have a dongle with Serial Number. Provide them S/N in the request to get SW free.

Peter, my last attempt: did you try to image INTERNAL EXPOSURE TEST ?

Every Service Manual for this machine has been printed on the paper for every certified serviceman and carries his name on the title sheet. PDF is not available. Any copying is a law violation.

For the first question: the error is the same like AGFA imagestters tell - spinner did not lock or PLL not locked. That means the speed of your spin-motor is unstable (based on spinner encoder signals) or did not reach some value of the speed for the certain period of time . Because Heidelberg's...

DEC board problem. Line thikness = Laser beam

It works fine in PC but you need Taipan RIP for PC or ApogeePDF RIP SoftWare with its own dongle. You have no way to save your money up to the last penny, some investments required to keep your Imagesetter running.

Top cover safety switches - root of problem. From my practice: roughly dropping covers or attempts to shift them caused plactic guides at switches broken and corrosion of contacts by evaporation of DEV and FIX as the second reason. Bypass them without any doubt!

You told us nothing to get an answer. Just for beginning: what type of plate do you use?

Azura TS plates have a color of emulsion lighter than others. Some optical sensors can't recognize the plate surface for imaging or for plate placement on the drum.

Any of UPAC boards is suitable for Galileo, does not matter which microcontroller version is onboard. Latest version were created to connect next CTP generation like XCalibur and Avalon
