Printing envelopes on OKI C9850

Hello everyone,

I am currently trying to print some laser safe envelopes (with window) in my Oki c9850.
Unfortunately the printed envelopes present some Show-through.
Does anyone has any advice for avoiding this situation?

Thanking in advance for all your helpful advice's.

Regards,

Nuno

 

try thicker paper setting - you need to release fuser roller pressure, try cardstock from thin to heavy - see if that will improve the issue.

 

Ok,

Thank you for your advice.

I will try it and see what happens.

Thank you for all your help,

Nuno

 

FYI - Side seams work the best.
