A crude chromatographic separation of the dyes in the dissolved toner showed that pink and yellow dyes were present. Solvent removal seemed most promising. These figures mean, among other things, that more of the papers which people will choose to save in coming years will be photocopies.
Ultraviolet exposure does remain a concern.
Ultraviolet can give you burns. Fitting an activated carbon filter to the exhaust manifold in the copier can trap ozone before it gets into the office, but proper maintenance of the filter is necessary to reduce ozone levels.
The sheet was slightly out of plane and the toner layer remained heavy in the area where the sheet was out of contact with the underlying blotter. Often two or three broad bands of color will run the entire length of the machine direction, caused by a machine "dirty" with toner accumulation.
Photocopies can be used as collage elements. In addition, the erasing appeared to diminish slightly the contrast of ink to paper. If a typical photocopied page of text has about 25 mg of toner 13then the affected sheets had easily at least 4 times more toner.
Artists found that the same sheet could be put through a Xerox color copier repeatedly to build up the thickness of the color layers, though at increased risk of having the sheet ignite.
Conclusions Electrostatic photocopiers and color photocopiers have entered the mass market in the last three decades. It is somewhat comforting to know that photocopies are a special challenge for the recycling industry because the toner particles are so difficult to remove.
The toner could readily be removed by dry cleaning with Mars plastic eraser, eraser crumb and a soft brush Fig.
Stability problems are of three types: Experience has shown that the binder resins in xerographic copies are vulnerable to blocking to adjacent surfaces with heat or pressure. The accidents all occurred on one copier model with a sloping paper feed on the left side.
Because ethyl acetate seemed to work at least as well as toluene in spot testing and because it had less unpleasant side effects on the conservator, it was chosen as the immersion solvent for this treatment. When an original item is liable to be copied repeatedly, a single master copy can be used and retained to make further photocopies, in order to prevent wear and tear and excessive light exposure to the original.What Are the Dangers of Sitting Next to a Copy Machine?
What Are the Dangers of Sitting Next to a Copy Machine? March 31, By: Avery Martin. Good Equalizer Settings for Audacity. Around The Home. Productivity. By: Scott Shpak. What Are the Parts of a Copy Machine? Around The Home. Xerox color copies appear to have a fairly good light stability.
Black xerographic copies can be expected to have good to excellent light stability, depending on the quality of the paper support.
The accidents all occurred on one copier model with a sloping paper feed on the left side. A 'photocopier' (also known as a copier or copy machine) is a machine that makes paper copies of documents and other visual images quickly and cheaply.
Most current photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner.
