How is double print on papers affect laser printer? -

I like to re-use paper for printing to save on cost and of course the trees, so I ll put those paper which printed only on one side back into the tray for re-printing on the other side, but I was told this can spoil or affecting laser printer roller feed, is it any truth in it? Thanks

When paper is printed on with a laser printer, there is always a very light, fine toner dust that is left on the paper other than the actual print (one user I had kept re-using sheets of labels and printing only 1 or 2 labels at a time and complained of how dirty gray/black the sheet kept getting after each printing. They too were trying to save money, but the result was the remaining labels getting dirtier with each time). This dust acts like an abrasive and over time will deteriorate feed rollers and retention rollers/pads, and cause paper feed problems quicker than if they used clean paper each time. Re-using paper as you stated will cause them to wear out quicker and cause them not to pick paper reliably or cause multiple sheets to feed at one time. Printers that are duplex printers and print both sides during the same print job use a separate paper path for the second side and therefore don t use the initial rollers that would be affected by putting the paper back into the paper tray for re-use (many people don t understand the difference and assume that it s all the same). The other problem of reusing paper as you stated is that once paper has gone through the fusing assy the heat removes most of the moisture content from the paper and resuing it will most probably result in poorer print quality and paper jams (usually due to static buildup in the paper since the moisture content of the paper reduces static buildup and it was removed in the fusing process. You will see evidence of this when pieces of paper cling to each other instead of separating easily.) Also the lack of moisture in the paper can cause the paper to curl which can also cause paper handling problems. You are welcome to reuse paper as you see fit as long as you are aware of the potential problems and side affects. Many people do this without much problem, but are confused when they do have problems surface and blame the printer instead of the re-cycled paper. Best of luck.

laser printers have a clean-up felt-face bar that scrubs off any unused toner off the image drum. so, for starters you are decreasing the lifespan of that scrub bar. previously printed paper will have a curl to it, chances of a misfeed. laser prints average about 27 to 50 cents apiece to print. too many people use the office laser printer like a printing press when they should produce one master copy and go over to the copy machine.
