    print jobs are coming out too dark/too light

    Canon IR 5185, prints documents perfectly fine. photos are the problem. Photos are so dark sometimes that it is unusable. changing the darkness on the machine does not seem to affect the photos. even on the lightest setting, the photos come out too dark for use.similarly, Canon IR3220 having the opposite problem, where photos are coming out too light. changing the light/dark settings does not change the photos. does not happen to everyone who prints to it.

      To be honest, i'm not quite sure what you are suggesting I do here. if you are suggesting i place the real photo over the dark one and make a new copy, that will not work in this case as we couldn't print the photo to begin with. it would come out too dark or too light.

          I should be more clear in my presentation of the issue. The issue is not with scanning a document, but rather printing documents with photos in them. Documents with photos come are fine, except the photos, which are too dark. This issue has nothing to do with the scanner.

              Funny crap. There are some suggestions in this thread that may help: http://www.copytechnet.com/forums/ca...ters-bold.html

                It has everything to do with the Scanner when u SCAN a document/book/newspaper/or magazine with a Picture/Photo in it--

                All trained Color Tech are aware of this-- DPI of pictures all depend on how they were originally scanned/inserted into the original document


                POST a copy of the document u are talking about

                in service mode make sure this setting is set to "1"
                in Level 2/
                for level 2 >u hit add funct(*) 2 key after u are in service mode Level 1

                COPIER>OPTION>BODY>SCR-SLCT is set to "1"
                Use low-line-count screen


                Select a level of sharpness to make the document more legible.
                EXAMPLES:
                1. Photographic images in news papers or magazines2. Blueprints or faint pencil-drawn originals3. For more defined outlines of charts, graphs, photos
                Low
                If you make copies of an original containing halftones,such as a printed photograph using the Photomode, screen clash may occur. However, by using“Low
                High
                This feature enhances the edges of original imagesso that the text is reproduced more sharply. This isparticularly suited to blueprints or faint pencil-drawn
                originals

                  Have you checked the machine or print driver for PHOTO MODE?Photo mode changes the machine settings so pictures are more of a half tone.The light Photo prints could be set for photo mode @ the lightest setting.If it were the copier, everyone would have the same problem. Sounds like OHS. (Operator Head Space)
                  Why do they call it common sense?

                  If it were common, wouldn't everyone have it?
