Digital BW, The Print

I've been printing my first few 2200/UT7/CSR prints.  I have some
faint, you need to tilt the print, marks left by the rollers.

They aren't ink marks, but just marks left by the rollers.  In 3 years
I've never cleaned the rollers, I never see this on EEM/PR etc.

So the manual says use cleaning sheets, the cleaning sheets that come
with EEM say never use them in anything but a 5000 model printer.

Anyone else seen these marks on CSR?  I've never seen them on Luster
or Glossy paper either.

Are there cleaning sheets for the 2200?  Where could I get some or do
I use Q-tips and some ? fluid.

Thanks

Neil
