As many of you who collect high end Agilent gear from the early 90's know CLIP's ( Component Level Information Packages ---schematic packages) are much coveted and worth their weight in gold because of their scarcity. I recently came by a CLIP for the 70300A which I am in the process of scanning when I ran into a problem with some of the pages
Many of you have seen that the ink used during the printing process at the time tends to "bleed" onto the facing page leaving a small residue and sometimes ghost image of the facing page. The ink I suspect was some kind of heat set laser drum printer process which made for very dark crisp lines when the manual was new . The problem is now occurring after laying face to face for 25 years in sometime not the best storage environment that the pages have become so bonded by the facing ink that they can not be peeled apart, or at least not peeled apart without damage to the ink and facing pages.
So a couple of challenges here 1) What would be the best way to peel these pages apart? Heat them in an oven for a while? how hot? How long?
2) Assuming I have a usable CLIP manual now ( and many of you do!) what would be the best we to minimize the problem going forward? Wax paper between facing pages?
This problem seems to be most prevalent for the most part to HP manuals of the era ( though I have seen it to a lesser degree on a very few Tektronix manuals)

Dave,
I've seen the same effect a few times with other Xerox/laser printed stuff.
FWIW, my guess is the fuser temperature was too low in the output device and the Toner was not properly fused to the paper
As to storage, I'd consider either:
Putting each sheet into archival, polyethylene photo storage envelopes. The used to be a company called Printfile that made such things, but it's been ages. I would NOT use vinyl. A cheap alternative might be 9x12 1 mil Ziplock style bags. I bought some for under $0.10 each. I use them a lot for keeping document pages together.
Put a sheet of glassene between the pages. I'm not positive this will work, but IMO it should.
FWIW,
-John

Dave,
Wax paper might work. I was wondering what the long-term effects of it on the pages might be, but then I remembered that people have been sticking flowers in books using wax paper for ages, with no side effects on the paper in the books that I have ever heard of.
Having said that, you might check Gaylord.com; they make library archival supplies. I've used them for years (although not to solve the problem you have run into).
The best long-term solution is probably exactly what you are doing anyway, which is to digitize the manuals.

You might try putting tension on the pages such that you are trying to pull them apart. Keep the force low and see if, in time, they begin to separate.
Once you have them apart, often you can adjust contrast and brightness when copying grayscale to minimize the unwanted images. Photoshop or similar may help.
Once you know which lines are artifacts, you can also remove them on screen manually (with a lot of effort).

I fear that heat might have the opposite effect, that it will fuse the image more solidly.

Dave,
Absolutely, do not use a steam iron!! It will make things worse-- a LOT worse.
Easy to prove... put any xerox'd page in contact with a new sheet of paper and iron it.
This cannot be a new problem. If you can wait a few days, I will ask an archivist at a university library what works and what does not. Drop me a note off-list if you are interested.
Best,
-John

I think you will find problems also with polythene storage envelopes, the slight advantage being they dont "stick" ....but I have a number of old manuals, and xeroxed copies, that were treated like this to preserve then in regular use.....and the ink/toner has transfered to the inside of the polythene wallet.. I dont know whether this is a plasticiser or electrostatic effect, but is is widespead across many manuals of different ages, so not a particular copier setting......Also the cover print "ink" is transfered to the white inside cover of the spring ring binders. So even impregnated paper may make it worse though tissue or waxed paper might help......trouble is wait 25 years to find that is no good either :-((.

Polyethylene doesn't have any plasticizers. Vinyl does, which is why I said not to use vinyl protectors.

Mmmm a bit painful Dave but you could try "ironing" a page though a sheet of paper to see if it releases the page below.....Maybe a job for the XYL, as I am told "men dont iron" (it is not true but in general we are not very good at it :-)) ) It is very difficult to find (smoothing) irons here that have flat plates and are not steam fed .....but the make nice cheap hot-plates if you can get one at a garage sale!
Is the toner powder coated with a a thin coat of thermo-adhesive ?

Mmmm a bit painful Dave but you could try "ironing" a page though a sheet of paper to see if it releases the page below.....Maybe a job for the XYL, as I am told "men dont iron" (it is not true but in general we are not very good at it :-)) ) It is very difficult to find (smoothing) irons here that have flat plates and are not steam fed .....but the make nice cheap hot-plates if you can get one at a garage sale!
Is the toner powder coated with a a thin coat of thermo-adhesive ?

Dave,
Wax paper might work. I was wondering what the long-term effects of it on the pages might be, but then I remembered that people have been sticking flowers in books using wax paper for ages, with no side effects on the paper in the books that I have ever heard of.
Having said that, you might check Gaylord.com; they make library archival supplies. I've used them for years (although not to solve the problem you have run into).
The best long-term solution is probably exactly what you are doing anyway, which is to digitize the manuals.

Dave,
I've seen the same effect a few times with other Xerox/laser printed stuff.
FWIW, my guess is the fuser temperature was too low in the output device and the Toner was not properly fused to the paper
1. I'd bet on waxed paper between the sheets. Even Gorilla glue doesn't stick to that. 2. I doubt that the fuser temperature is too low--I've seen the same toner transfer to the white loose-leaf binder from pages printed on a pro-quality LaserJet. I think it's just the nature of the beast. --doug

Toner transfer is a well known method of producing printed circuit boards. Print your mask onto paper with a laser printer, lay the paper onto your copper board and heat with an iron or pass through a modified laminator. The toner transfers to the PCB and acts as an etch resist. -- Stuart Winsor Only plain text for emails http://www.asciiribbon.org

The transfer to binder covers is because the vinyl has plasticizer in it that migrates to the surface.

Easy to prove... put any xerox'd page in contact with a new sheet of paper and iron it.
This cannot be a new problem. If you can wait a few days, I will ask an archivist at a university library what works and what does not. Drop me a note off-list if you are interested.
Best,

Maybe if you could warm the offending pages while you carefully peel them apart? Obviously you don't want to add any compressive force, that would just make the problem worse. . .

When I read the "steam iron" suggestion, I was visualizing not ironing the pages, but steaming them. If you saturate the pages with moisture while pulling them apart, maybe you could encourage the "receiving" page to soften and release a few fibers of the paper rather than from the "master" page.
Of course, the steaming should be done from behind the receiving page which would -- we hope -- encourage that page to release the stuck toner from its surface rather than from the master page.
But if you've got 3 pages stuck together... dunno.
No solution will be perfect.

Don't worry about it -- rip 'em apart.
Then scan both (the master and the "stuck" page), reverse one image, align both so they make a whole image again.
