Digital BW, The Print

I'm trying to set up my R1800 with Paul Roarke's 3MK approach.

Do I need cleaning cartridges or not? I'm seeing what appears to be
conflicting information on the MIS website. I still have the OEM carts
in the R1800 and plan to replace the PK, MK, and GL positions with
Eboni ink. I've capitalized the parts that seem to disagree.

1) on this page http://inksupply.com/epsonclean.cfm

I read this:

Purging Desktop Printers
Cleaning cartridges for Epson printers are not normally required on
Desktop printers before installing MIS inks. However, if you have been
using inks from another 3rd party, like Lysonic, you must purge this
other ink from the printer before installing the MIS ink. IF YOU HAVE
HAVE ONLY HAD EPSON INK IN THE PRINTER, CLEANING CARTRIDGES ARE NOT
NECESSARY. This does not apply to Continuous Flow Systems. A new
cartridge set is required to change inks on a CFS.

2) but on this page:  http://inksupply.com/R1800_bo.cfm

I read this:

The full color cartridge set is offered here for your convenience, and
are exactly the same as our MIS cartridges for the R800/R1800
printers. If you are currently using R800/R1800 inks that are not OEM
we recommend switching to Inksupply.com color inks to avoid ink
compatibility issues. ADDITIONALY, WE STRONGLY RECOMMEND THAT YOU USE
CLEANING CARTRIDGES TO CLEAR INK FROM THE LINES PRIOR TO THE USE OF
EBONI and before switching back to the original Photo Black and Gloss
Optimizer cartridges.

Maybe what makes the difference is using Eboni...

Thanks again, everybody.
