Hi all. I print A7 (7.25 x 5.25) announcement envelopes on the back flaps (mostly small logos and return address text) using a Xante impressia which is a rebranded Ricoh SP c820dn. My biggest problem is that I get a background overtone. The biggest culprit seems to be magenta (but can be other colors).... tiny specs of toner all over the envelope. Wouldn't be a problem, but when you open the flap of the envelope you can clearly see the perfect line where the flap shielded the part of the envelope from the toning, giving the envelope the appearance that it's dirty in the toned areas. No problems ever when running monochrome black, just when colors are engaged. I use oem toner and drum development units. I have spent hours upon hours tweaking the charge voltages and the concentration of the toner to developer. Sometimes I can get it to clean up for a bit. Usually it's the worst when I start up in the mornings (temperature or humidity doesn't seem to matter)
My biggest question is, does someone know of a printer with a relatively flat paper paper path that has a bypass tray I can push an envelope feeder up to? Of course, I am looking for something that prints clean in the background.
I'd like to stick with a toner based machine. I have tried inkjet, and the quality sucks. inkjet coated paper isn't available in the sizes and quantities I need to make envelopes in volume.
Other than that, if someone has any ideas on how to stop the overtone on my ricoh, I'm all ears.
Thanks!
