#1 Julien, The flakes are small pieces of rubber from the carriage belt. This is wear and tear on the carriage belt part. As long as you are doing your daily/weekly maintenance, such as lubricating the carriage rod, it will keep movement on the printer running properly. You can clean the flakes out with a dry cloth and look for any remaining flakes on the platen/print area and clean as needed. Avoid touching the encoder strip. A vacuum cleaner can also work but be extra careful not to hit anything. If you notice more than usual amounts of flakes then your belt will possibly be due for replacement in due course. If you re unsure of any cleaning procedure please contact a Service Technician and they can show you suitable cleaning procedure and also check the belt.

OK, I understand, Then these tiny black chips that come from the belt are absolutely normal? Or you think that I will have to replace the belt ? The beld should be replaced on SMK1 service, isn't it ?

The printer design takes into account the belt particles and collects them so they do not fall on the print. If there are excessive amounts then there could be an issue and you should contact your reseller

Hi, Thanks for answer. I don't know if there are excessive amounts of belt particles or not. For sure there are more quantity of particules now than 2 years ago when the printer was all new. What do you think about the two pictures I linked on my first message ? (you can see the amount of particules) regards

The number of particles will accumulate over time. If that is the total from 2 years then there shouldn't be an issue. However, if the increase is recent you should contact their reseller.

Hi Sonia, Yes it's the total from more than 2 years use, we never clean these particles. There is a little recent increase but we print a lot more. I think you should inform the customers in the user manual so that they don't worry because it's a bit alarming to see all these little particles accumulate over time. Then you think that the total amount of particules you can see on the 2 pictures is absolutely normal after more than 2 years of use?

It seems normal to me. But, I am not in front of the printer. Just judging from your picture.

Hi, I just have a question. I don't know why but the belt seem dirty with ink residue. Is it necessary to clean it from time to time?

No maintenance should be needed. What you are seeing is provable remains from condensation. You should ensure that the environmental specifications are being followed.

Hi Sonia, Yes, you are right, it is remains from condensation because there is lot's of condensation when the printer runs especially when there are a lot of dark color dishes. The room surface is about 70m² and temperature is always between 18° (minimal at night/winter season) to 25° (maximum in Summer season). What can I do to improve the situation? You are sure that I don't have to clean remains from condensation on the belt ?
