    Periodic Maintenance Charts.

    I work with a bunch of Konica Minolta machines and was wondering if the periodical maintenance charts are worth following/ordering ahead for most things. I'm sure a lot of things don't have to be really replaced at the time they say. Or am I wrong? I am very new to printer maintenance and don't know what to look for exactly.

    Re: Periodic Maintenance Charts.

    You're going to get a very wide range or reactions to this question.

    I guess the best answer I can give, is that it's an item-by-item decision. There are specific items, for example: xx8 series drums. They barely make yield. I replace them if they make it close to yield. Other items can get a greater count without causing damage.
    For a useful answer, I think you'll have to be more specific: what model? which consumables? =^..^=
    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.

      In my experience you'll get called out for silly / radom issues by the users before PM cycle is due. But as a general rule keep the device clean.

      Also how far have you had to travel, if the client is a long drive away etc then I would stick to the PM cycle.

      Feed rolers for example are pretty cheap so I replace them early at around 50 - 80k if the client is using standard paper stock.

        I haven't followed the OEM's maintenance schedule for many years now. All consumables turned off and replaced only as needed. Most of my machines are the 20ppm to 60ppm segment.

        Think it would be different if I had "production" models in print shops, etc and would do the OEM suggested maintenance by the book.

          As long as you have an MCP "minimum call procedure", which you carry out every visit, the machines should hopefully be reliable. I've currently got a C258 in an architects office, where they print loads of A3 colour, all of the drums are "over life" between 125% and 250% and also the transfer belt as well, and they're still getting good quality prints
          Tip for the day; Treat every problem as your dog would.....If you cant eat it or f*ck it....then p*ss on it & walk away...

            The copiers I have to maintain here are a 1250P, C7000, 751, (2x) 754, 3070L. So quite a range. RIP. For a lot of the rollers we use rubber rejuvenator here. Seems to make them last far longer if cleaned semi-often with the stuff.

              Rubber rejuvenator and/or WD40 can help you get more life from rubber rollers, but it has diminishing results. By the time I'm digging out the WD40, I'm also ordering replacement rollers for the next visit.

              It depends on your point of view: If you're a tech billing $200 for an hour, it's a lot different that living there onsite. You can dig out the cleaner anytime. =^..^=

                Good point. For me it would be later scenario.

                  Re: Periodic Maintenance Charts.

                  An old rule of thumb, if you 10 machines in the field that use the same feed rollers, keep at east one set in stock, preferably car stock. If you have a customer that is an hour drive away, you want to make as few trips as possible. One thing about most manufacturer's maintenance kits, if the PM chart calls for replacing the feed rollers at 300K and the basic configuration comes with 2 tray, the 300K maintenance kit will come with 2 sets of rollers. Do not just replace the rollers just because you have the new ones. More often than not one tray get the usage. Hang onto the unneeded rollers until you actually do need them.

                    What is car stock? And yes i think a bunch of the machines here use the same rollers so I should make sure we have backups.

                      Parts that you carry in your car.

                        That would be items (stock, parts, etc.) that you keep in your vehicle (car, truck, van, etc.) to have with you all the time, as opposed to having to get things from your office or warehouse. Generally things that you use more frequently, like feed tires / rollers.

                          Happens all the time. Some people read the original and reply without reading what others have replied. Actually I like your reply better than mine.

                              i usually replace them every time i visit a customer if they dont call us more than 1-2 a year. For most Customers this does the trick
