      i dont think you can attach files too big or perhaps before your 10th post (some forums)
      We know a thing or two because we've seen a thing or two.
      The medication helps though...

        Ok..
        1) I take it the machine is rated for 350gsm?
        2) What settings are you using in the driver?
        3) You are using mpt to feed paper?
        4) Are you sure fuser/belt/drums in good working order?

          Couldn't find in Board FAQs limit per posts to add attachments, but may be wrong on this.

            I hate to be the bearer of bad news, but you know this machine is 11 years old, don't you? It's not that it can't be fixed, but if they haven't stopped making parts yet, it will be soon. How much money are you going to throw at a machine headed to it's grave? =^..^=
            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.

              apologies Phil B

              The total Print count is 1.3 million

              From what I understand, its had a full service, I.e all major parts changed. Which is what the engineer advises I do once a year. all parts are Original.

              Due to the nature of my business. I specialise in large format printing. I possibly don't use this machine as much as a regular full time printer.
              for this reason the machine isn't on a click contract. However they have advised this is possible in the future when I increase my prints. Its obviously getting more and more use each month.

                I tried compressing the images before uploading, even tried different formats

                  Hi

                  1: I'm not duplexing the paper. Never seems to give me trouble, also,I'm getting the issue with the spots on every paper weight if printing pastel colours
                  2: Paper weight 357/300g/m2, Paper Type-GL, Duplex off
                  3: I'm using The side tray (Tray4 LCT)
                  4: Fuser/belt/drums should be virtually brand new. Just had a major service in which I was told all major parts have been replaced with new original parts

                  What would possibly help more, is you guys seeing the photos. I'll try to upload to a different site and link back to this post

                    I did try all this before posting the original post, I'm now thinking it might be an issue with firefox. As I've also had issues with responding to some of your responses over the weeken

                      1.3 million
                      All major parts were serviced in Jan 2019, full service,
                      I've been advised to have the machine fully serviced ones a year
                      All parts are original

                      Regarding moisture, honestly the room itself seems fine. Even outside the room, I don't feel as if we have an issue with moisture

                        Not to worry my friend, I am aware.

                        Reason for the post is to see if it can be something simple. The machine has a count of 1.3 million, was serviced throughout its life by the original engineers who I've purchased the machine off. They still service it for me. Obviously I'm trying to resolve a problem, they haven't managed to resolve.

                        Id kick myself silly if it was a simply thing which was being overlooked

                          Please have a look at the following. I'm still having issues displaying high resolution images in this forum, if you cant see the issue with the below images, please have a look at this link:
                          Image quality issue Minolta C5501 - Big Print Birmingham :- Tel: 0121 673 2741
                          You should be able to notice spotting in the whole print. This happens when printing pastel colours, it happens on all types of paper. 150gsm silk/ gloss uncoated all the way up to 350gsm stock.

                            I'm attaching photos of my most recent job. Business cards on 350silk, the background colour is a salmon/pink. I can clearly see ghosting/spotting in the print

                            Id really appreciate your advice

                            I cant seem to upload images of the prints. I've saved the files in various ways. But keeps getting rejected by the upload module in this wysiwyg
                            Firefox has limitations when uploading to this forum - I use Internet Explorer / Edge to upload here.
