I purchased a second hand Mitsubishi CP9810DW printer recently and im currently getting some strange intermitent marks on some of the prints.

When I first bought the printer I tested it before purchase and all seemed well. It had around 20 ish prints left on the media and all still seemed well. I have since recently put in new media and now I am getting some strange marks on some of the prints. It does not happen on all prints and only ever appears on light tones but not all the time.

My initial thought was that the print head needed replacement but most people have been telling me that if that was the case marks would be on all prints. I have sent an email to a couple of people to try and shed some light on it but thought i'd pop a scan of a print up on here to see if anyone has come across anything like this before. The scan is fairly acurate as to the visability of the marks.

I have seen this kind of mark before, but I am not sure excately how it got there, sorry.

My initial thoughts were muck near the thermal head. I am sure soem the event guys will answer in due course, if they aren't too busy right now ( it being a busy time of year for them).
 
Darren,
It looks very much like ink starvation to me. That , probably one of your colours is printing intermittently. If so, it could be a problem with your printer head or whatever ink system feeds it. If it were an inkjet printer, I would say that you could be running out on a cartridge or have a faulty cartridge.( It has happened to me in the past) But I don't know how the sub dye system works.
Hope you soon find an answer.
 
It's a dye diffusion thermal transfer photo printer ( D2T2 ), or more commonly referred to as a 'dye sub' printer.

It's a dry process, no ink, just a ribbon with dye in it.

The principle is still the same as colour is not printing properly,so perhaps you have a faulty consumable. Process of elimination i'm afraid.
Try a new one, if you have not done so already, and go from there.
 
With the greatest respect the principle is not the same.

However we cannot rule out the print media at this stage, although I tend to think it could be an electronic or mechanical issue.

From what I understand Darren has been speaking to an engineer at Mitsubishi so hopefully they will get to the bottom of it.
