Hi Guys

New to the forum, this is my 1st post
I'm kind of new the print industry, bought my own KM C5501 2nd user from a company who serviced the machine for previous client.

I've had the machine for around 1.5 years. during the heat spell I noticed that we were getting a lot of faint spotting on light pastel colours.

Had the engineer look at it, he put it down to moisture in the air. Which made sense when it was hot. Not so much when its cold. I cant really feel any moisture in the air.

Since we have had it, it has had various parts changed. around 2-3 months back. Its had a full service totaling over £1400

I was expecting this to have resolved the faint spotting issue.

Spoke to the engineer again. Asked me to refresh the toners from the adjustment menu. this hasn't helped, it's £90 for a call out charge and clearly they cant seem to resolve the issue as I have mentioned it to them over the last 3 visits

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

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?

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? =^..^=

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 (http://bigprintbirmingham.co.uk/image-quality-issue-minolta-c5501/)
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.

Go into the service mode and print test pattern 53 (if i remember correctly) and change the cyk to 0 and the m to 80
and see if the spots appear, and then do the same for the other colours this should then show if its 1 particular colour causing the problem. load up your results.

And to be honest £1400 doesn't cover all the parts on this machine that could be causing the problem.
Could you also load the parts counter list which is on the Utility screen.

Thank you for your response. I'll do the test patterns as soon as I get back to the office

As for the cost, that's what they deem to be a full service,

have seen this before, are you using oem toner? what is the actual count on your developer units. this can be caused by damage to the developer sleeve. (usually caused by somebody with a vacuum). i would do the charts to determine what units are causing the problem. have seen aftermarket toner grind the coating from the developer sleeve.

Thank you for your response. I've always used oem toner. To be honest I did look in to buying after market toner, But couldn't justify the cost. Its cheaper to buy genuine.

I should mention one of the reasons I moved away from xerox was that I could just call an engineer. Looks like I'm back to square one. Finding a solution to my problem.

Problem with the count on the developer is for some reason the engineer didn't reset it. I asked him why, he mentioned that they keep a full log of what's done on all jobs/machines on internal system.

Hi Gaffers

I don't blame you if you want to virtually slap me silly.

I have printed test patterns in the past, however I cant seem to do it now, my mind is completely blank. I manage to get in to service mode by soft booting holding down utilities/ test pattern Mode. I even enter all the information

Pattern 53
Y /0
M /80
C /0
K /0

What do I do next to actually get the machine to print the pattern, pressing start doesn't work. 42096
what do I do next:(

Haha no problem, there should be a Copy Screen button at the bottom If I remember which will take you back to the screen you would normally see and you then make sure that colour is selected and which tray you want to print from. And then when printed press the button at the bottom right to return back to the test pattern screen.
