my prints are undersizedgreenspun.com : LUSENET : L-F Printers : One Thread
We use an encad pro 50 with our Onyx rip server . We consistently find our large prints falling short in letgth, not width, just length. Whats up with this? Did I miss something in the manual? Is anyone else experiencing this? What is recomended?

Clean the traction wheels on the printer with alcohol and a soft bruch like a toothbrush. A glaze can build up not allowing the paper to be pulled throughat the right amount for each head pass.

I have the same problem. I have an HP2000 only on some files. One in particular is an EPS. Consistantly short on length on all 80 that I printed. I can't see how cleaning anything would fix such a consistant problem

I have a Novajet III and have the same problem, but in both directions. We sometimes are off by as much as 1/4 inch. We just over size slightly to get around it, but it is a pain on tight prints.

You can do an XY Calibration on the Pro50 but you must make sure you enable the calibration in the control panel. I believe the default is off. You can do the calibration over and over again, but it has no affect until Use XY Calib is turned

I have a HP Designjet 3000 and my prints are falling short by 1/4" as well.

Our HP 3000 also produces inaccurate lengths especially on long (over 60") outputs. In addition, accurately sized post-script images coming from Photoshop 5.0 into Postershop will resize with inaccurate magnification in the main .ONX window. Its a pain to always check for accuracy on a large (over 60") tradeshow panel, adjust for accuracy and still have postershop or the HP output long or short without any quantifiable reason.
What's going on here?

I have HP3000, and Three Encads and experience the same problem. I have determined that the material I'm printing on is actually expanding in the printer (pressure Sensitive vinyl on paper carrier). This has caused the width to be off slightly but the lenght is usually short Monday I am starting a 24' by 32' of (24) 4'x8'panel of One Image. and am really nervouse Can someone please give us some input???

Located part of the problem!!! I use Pressure sensitive vinyl which has a tendancy to buckle instead of rolling on humid days, therefore I use a roll weight similar to the ones that come with the HP3000 except it's a 10" round tube of 20ml Lexan which is pretty light. For a 24 panel mural I just completed, I used a 50" cardboard 2" core which is heavier and all 24 prints were very consistant in length. I also weighted the roll when fresh until it was attached to the take-up roll. This really seemed to help. I know it sounds like Yankee Rigging but I was satisfied with the end results

For all of you with a HP2500, 3000, 0r 3500 you need to go to FULL MENU, DEVICE SETUP, PG. ACCUR. on the front panel and change it from "optimized" to "Constant" or "Maximum" Maximum is supposed to be the most accurate, but you may see banding in your image. Your media will also play a "big" part in your accuracy. Thicker medias on the HP tend to not advance as smoothly as thinner medias. I just automatically add .2" to my length width in Postership when printing to our HPs.
