What do you measure??
Read my post under RIPS and film positives thread about the nightmare with the Xante Screewriter 4.
At least you can get an Epson repaired and for less money than the Xante.

I was sorry to read about the troubles you had with your ScreenWriter4. I never had anything like your experience. You never get scared until you get robbed once.
X-Act is software to modify the Postscript output so you can calibrate the exact size of your image for registration purposes. Anyone that has owned an image setter or piano, knows you have to regularly tune the piano quarterly and the imagesetter twice a day. You have to measure the size of the image.
The reason Xante supplied you with a plastic ruler was so you could use it with X-Act.
Xante Accurate Calibration Technology (X-ACT)
X-ACT overcomes the limitation of horizontal and vertical dimensional accuracy common to all laser printers, giving you a new level of control over printed output.
Laser printing is an involved process that uses an assortment of finely tuned, moving parts. As a result, tolerance varies from one printer to another.
For example, if a letter-sized image is printed on two different printers, the image from one printer may be 10.98 inches tall, while the image printed on the other printer might be 11.1 inches tall. The height of the image may vary from printer to printer.
The X-ACT feature provides an easy, convenient way to calibrate your printer and achieve precise control over horizontal and vertical dimensional accuracy, ensuring output of unmatched quality.
Without X-ACT, tolerance on a printer can be as much as one percent (1%). That means a 12-inch (304 mm) image can be off by as much as .12 of an inch (3 mm) (almost 1/8 of an inch). When one printer enlarges an image and the next printer reduces it, this inconsistency is magnified.
The difference between the sizes of the two images can be almost .25 inch (6 mm). Compare this value with the reduced tolerance of the X-ACT feature: over the same 12-inch area, X-ACT can provide accuracy to .02 inch (.5 mm) (1/64" = .015625). As you can see, this is a tremendous improvement in dimensional accuracy.
