    General question regarding intentionally poor print quality.

    Hello, I recently picked up a canon pc 425 copier and it all works fine, but I'm actually interested in intentionally messing up the print quality for artwork. So my question is, what are some things I can do to intentionally mess up the print quality without totally ruining the copier itself? Things like faint print, blotchy printing, etc. I quite like the look of faint print, and the copier does actually have a dial that changes the lightness of the print which I find can be useful, but I also find it looses too much fine detail when doing that. I'm not too terribly knowledgeable about this kind of thing so hopefully this is the right place to ask. I'm open to all kinds of suggestions for this probably somewhat weird question, Thanks!

    If your Canon is mono-compunent, and I suspect it is, you could make some fingerprints on the developing cylinder. Mono-component machines will do something called "mottling" when the toner is contaminated with finger oil. When you've had enough mottling, you can just dry-wipe the developing cylinder.

    I can't say as I've ever had anyone ask intentionally for bad copies. ?? =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

      This is a technical forum but if you must try feeding heavy paper/card though you will get poor print quality etc.

            Thanks for the insight! Just to confirm, is the developing cylinder the roller on the inside of the toner cartridge or would it be inside the unit itself?

              I haven't seen one of these in a very long time ... but when you remove the toner cartridge you should see the developing roller with an even coating of toner on it. The drum will be clean. Anybody remember better than me? =^..^=

                  You can try running thick card stock through at a thin setting that might leave toner on the fusing surface that might offset onto the next sheet of paper.

                    IIRC, this machine has a CIS with lens array stuck onto it, no "lens" like you'd think of it. But you could get it dirty. =^..^=

                      Thanks for the replies guys, definitely some fun suggestions. I also might try refilling an old empty cartridge the copier came with to see if any possible mechanical wear will create interesting texture. Though probably not as much as directly messing with the components I would assume. Perhaps mixing techniques?

                        Wrong toner would definitely be interesting ... but messy, and hard to clean up after.
