    falcon 3, density and fax issue...

    Under system menu> user adjustment lies "printer density." There's this machine that likes to set to "1" instead of "3" even when I set it to 3.

    When receiving fax, cas1&2 are loaded with letter/R, when source set to auto it printed out fine. When set manually on both cassettes, darn thing wouldnt print and end up giving me paper mismatch. The reason why I set to manual is the cassetts randomly report false size.

    Its not user error. Do i have a faulty memory module/board?

      I have had exactly the opposite problem with the Falcon III series. This machine is designed to continue to print fax onto whatever paper happens to be available in a very specific order, starting with the closest paper match. My customers have complained that the machine will not ask for letter sized paper when it's out, but print onto legal, ledger or whatever happens to be available. The only way to make the machine ask for paper is to specify a specific media type for fax printing, then set up a tray with that media type.

      If you're having problems with the trays not displaying the correct size, with it set to Auto paper size, then you'll need to clean or replace the paper width detection PWB in the bottom of the tray. Often, just sliding the guides back & forth a few times will scrape off the corrosion on the contacts.

      For the density issue on faxes only, I think I'd start with reloading firmware v 2.45. If that didn't help I'd re-initialize the fax memory in simulation U022. First backup any user data in sim U917. Afterwards remember to reset the machine's destination, SMTP and IP address. =^..^=
      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.

          cas 1 > letter, cas 2 > letter R, these are set manually.

          when fax comes in, it shows the paper selection screen and ask for letter R. When paper source is set to auto, no problem.

          The density issue is not isolated to fax only, for general printing, tho for today it worked fine.

              So what's wrong with "Auto"? The machine can accurately identify the correct standard paper size.

              Are you saying that the machine defaults to a density setting of "1" rather that the usual "4"? =^..^=

                  The problem with auto is as the copper "brush" age the position it sats in start to have slack, it will have mini lateral movement. When this happens the machine will think it has ledger/letter/legal/R by random(i did clean the contacts). Setting it manually remove the size detection portion, so the machine doesnt think, and the problem will never come back. Client didnt call today so I assume it was working fine.

                  Yes, the density goes to 1 instead of the usual 4(3?)

                      If it were me, I'd fix the width sensors.

                      That density setting is just strange. The firmware might help with that. =^..^=

                          you mean the copper track and brush or the receptor on the frame?

                          edit: no call so far, last setting for cassettes was on auto, seem to be ok for now.


                          thx again

                              Yes. (both)

                              Also make sure you don't have any paper jammed in the modular connector.
                              I had one of those learning experiences in one of these situations.

                              It was a CS-3050, and I noticed that I was getting "- - - - -" for the paper size. Sure enough, there was paper scraps in the connector. I got out my dental probe and start fishing for the paper scraps. I was a bit surprised by the sparks, and the screen going blank. (Damn! ... conductive probe + current = blown main board. I should have thought of that.) Fortunately for me, after powering down, removing the scraps, and powering back up everything was still functional and I got size detection back. I won't have to repeat that mistake.

                              The first time I saw this sort of problem it was lens position codes on a Mita DC-513. This machine used a similar arrangement of copper pads on a circuit board and a three contact copper brush that dragged across it to determine lens position pre-sets. Any kind of lubrication is bad news. Once the board is cleaned with alcohol to remove any lubricant, you can clean the board contacts with a pencil eraser. Don't make the mistake of brushing away the eraser dust with your finger. You just contaminated your clean contacts again. ElectroKleen does both operations at once (it's the best/most effective choice): http://www.glasermfg.com/electrokleen.htm . Don't try to bend the copper "brushes". They usually end up mangled beyond use after a little tweaking. If there is any lubricant on the brushes you might try a little gentle cleaning with a Q-tip and ElectroKleen. (I think I might still have a spare lens contact PWB and brush somewhere. It's sad, really ... I'll use it on the very next DC-513 I see.) =^..^=
