    AR-407 Toner Supply

    I'm having problems with an old Sharp AR-407. The machine keeps displaying "Toner Supply is low" and about once a week somebody adds toner even though the tray is full. It has gotten to the point where I tell the people to cycle the power to get rid of the message that would force them to add toner.

    Can anybody help me clear up this problem?

    Thanks,

    Mark

      Are you using OEM Toner? Is the toner fresh? are they shaking it well?


      May have to vacuume out and start fresh dev. and toner

          The toner is new as of about 3 months ago (Sharp AR-400NT) and were well shaken before putting in there.

          I might try the cleaning trick and see what I come up with.

          Thanks,

              I think you are missing the point, it's Not just a matter of 'a cleaning trick', but of 're-Value-ing' the Developer and checking Tonerflow....

              Your problem may not be solved by this proceedure....

              This model will report 'add toner', when the copy image has been over the 8% of standard Black coverage for more than 20-40 continuous copies ...the Machine cannot compensate for the extra Toner being drawn from the Dev Tank and believes that the Toner supply has run out..

                  johnbla is right. They must be running some pretty heavy fill originals. If you can verify this for sure, I have an old Mita trick for you:

                  On the Mita DC213 The machine was unable to keep up with toner usage. Our answer was to take needle-nose pliers and create small divets (or valleys) in the foam roller in a grid pattern (so it feeds evenly) to increase the the amount of toner being fed through. Now I mean small divets (1 to 1.5mm), not any bigger, and maybe a total of 25 or less on the whole roller evenly spaced. Maybe a pointed object might work better to perforate the roller on the Sharp.

                  If you start getting F2-00 or F2-02 its dumping toner in too fast. That's why I said make sure that they're running heavy fill. You can create a secondary problem. And you can't put the foam back, so if it doesn't work you'll have to install a new foam roller & seals.

                  All this being said, its fairly unusual for a customer to deplete the toner as fast as you describe on a Cougar. I know of only (3) occasions, and they were all real estate agencies copying pictures of homes.
                  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.

                      I have 5 churches with Cougars and every Friday, when running off the 'Order of Battle' for Sunday, they regularly have this problem... caused by excess coverage on their pamphlets.

                      I have tried various methods and have yet to find one that fits all occassions......

                      So I try to 'train' customers..... if they want the 'extra coverage' they must be prepared to do smaller runs ~ 40 max and to cycle the power to re-value if required..

                          johnbla,
                          Why don't you take a try at perforating one of those foam rollers. I really think it will work for you.

                              I would put the thing in toner save mode before I touched that foam roller.

                                  The resulting loss of fill will be a hard sell to the customer. Toner Save looks like crap.

                                      As touchy as those foam rollers are I'd have to be in a hard spot before I tried it, although I will keep it in mind.

                                          I have to agree with Choice, I would not mess with the sponge roller....

                                          Although I did try 4 longitudinal cuts into it, as a trial for the one of Churches, but had too many F2's when they were doing 'normal' copy.

                                          Also adjusted/varied the range of the DevConc 'off target percentage' to give a bit longer before 'add Toner', but gave grief in PCQ..

                                          They have to live with it... or Up-Grade to something that can deal with it....
