Problem Printing Tyvek on OCE Colorwave 600

We are having issues with our OCE Colorwave 600 when printing on Tyvek 68gsm [Code: 8740D]
We are getting regular 'Head Crashes' that leave ink marks on the paper and then after 2 or 3 sheets will stop with an error message of 4702.

Can anyone assist?

 

I have the same problem...please any help !!

 

I'm looking for an affordable solution to color print on tyvek sheets (6.5 x 11"). I'm seeking a high resolution digital solution. The volume is 15,000 sheets per year. I would prefer to use an inkjet or laser solution. From what I understand the processing temps need to be below 200F....

Any guidance would be much appreciated.

Thanks
