    AL-1655CS Tray 2 problem

    All of a sudden this machine started doing this. Using the bottom cassette the feed rollers don't move and the cassette light starts flashing. The display says "Add paper to tray 2" and there is paper in it. When the cassette is pulled out, even an inch, and put back in the light stops flashing. Trying to make a copy it may give you just one and it starts again. Never saw this before.

    The cassette is programmed for the right size of paper, the switch in the back knows cassette is in. Upper cassette works fine in its place but same story when I put it to the bottom. Please help. Thanks in advance.

      You already beat me to the easy things. You've probably already seen the paper trays programmed to the wrong paper size. It gives symptoms exactly like you described. Feeds one, then jams after paper hits the exit tray.

      I seem to recall greasable spring wrap clutches (not sure) in the drive. I think I'd clean those clutches next.

      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.

          Hi, blackcat4866!
          After going through 06-01 test I noticed that the solenoid plunger doesn't go all the way into the solenoid therfore not releasing the clutch. There can be 2 things - either there is some dirt inside the solenoid (70K on counter), like crumbs of developer, or the solenoid has lost its strength. I am going there tomorrow with another solenoid (just in case). Thanks a million for your response.

              Most Sharp solenoids do not have any adjustment. Developer in there is a distinct possibility.

              When you do get an adjustment slot, adjust the solenoid so that you have the minimum amount of throw and still performs its function. To phrase it another way, you want the greatest amount of plunger in the solenoid, for the quickest response, and the most strength.

              Also, no lubrication in solenoids. I don't know how many times a tech has disabled his own machine by squirting oil (or worst: grease) into a solenoid "to make it slide better." It just gums up the works. Clean with alcohol.

              If there is a noise damper on the top of the solenoid, make sure that it has not gotten sticky, delaying the release of the solenoid. When that is a problem, I'll clean off all the foam and two-sided tape and insert a small disk of black tape in it's place. The adhesive won't get pressed through the tape like it does the foam.

              I doubt that you'll find a bad solenoid. I haven't replaced one in years.

              Good luck. =^..^=

                  The solenoid coil turned out to be weak. I replaced the solenoid. Everything works fine now. The last time I replaced a solenoid was around 1990 on old SF-8500. This one has neither noise damper nor an adjustment slot. Moreover, the solenoid has a centering "bump" that goes into the round hole in the plastic base it's screwed on. In other words, there is no positioning adjustment. I thank you muchly for your active desire to help and I appreciate you knowledge and experience. Have a nice weekend.
