I just roll up the paper until i get a cylinder where the marks line up.

Do you see that 6"/150mm scale in my shirt pocket? That's what it's for.

Developing related problems are a little more tricksy. Since the developing roller rotates at a different rate and in the opposite direction as the drum, you don't get a direct correlation between interval and roller diameter. If the manual has a repetitive defect chart that's nice, or maybe you just made a note to that effect in your database for the next time.

You mean this isn't just common knowledge? I think Archimedes made the first fairly accurate measure of Pi in 250 BCE. Most of us have been calculating circumferences since elementary school. Depending on your age, that might be quite a while ... or fairly recently. =^..^=

I hadn't really thought about roller compression being as much if an issue as that previous to this post. In general I have to replace rollers for damage, or them just not picking up paper due to loss of tread before they cause timing issues. However I've had a 283 giving me fits, and you can bet I'll be checking it out Monday armed with new knowledge. Thanks.

It's surprising how peaceful they are with each other.

Re: The random thought thread

... In keeping with the cylinder ratio :
An unwanted periodic pattern appears on a print out, what is the length of the periodic pattern in relation to the cylinder that caused the problem ? How can we quickly find out if the unwanted pattern is coming from a drum, dev,rego roller etc..?

Given: We know the unwanted pattern on the print out is periodic.
Using the print out, we make a quick mark using a pen at the offending period marks on the print out. We can then roll the print out paper into a cylinder until the pen marks align. The alignment will leave the diameter of the offending roller or cylinder. Alternatively we could measure the distance between the pen marks and div by ratio Pi to arrive at the offending diameter ...

Re: The random thought thread

The teacher gave her fifth grade class an assignment: Get their parents to tell them a story with a moral at the end of it.

---The next day, the kids came back and, one by one, began to tell their stories.

There were all the regular types of stuff: Spilled milk and pennies saved. But then the teacher realized, that only Janie was left.

"Janie, do you have a story to share?"

"Yes ma'am. My daddy told me a story about my Mommy. She was a Marine pilot in Desert Storm, and her plane got hit. She had to bail out over enemy territory, and all she had was a flask of whiskey, a pistol, and a survival knife.

She drank the whiskey on the way down so the bottle wouldn't break, and then she parachuted right into the middle of 20 Iraqi troops........

She shot 15 of them with the pistol, until she ran out of bullets, killed four more with the knife, till the blade broke, and then she killed the last Iraqi with her bare hands."

''Good Heavens, 'said the horrified teacher. What did your Daddy tell you was the moral to this horrible story'?"

...."Don't Screw with Mommy when she's been drinking."
