Digital BW, The Print

Bob,

Sounds like it might be ink starvation in one of the carts.  They need to be
replaced after heavy useage.  The fact that it is intermittant is an
indicator.  Try elevating the offending bottle 2", let it rest for a few
hours, then print.  Mine does this yearly.

Having a problem with intermittent banding on my 1160. The printer
has a nomorecarts CFS and MIS VM ink. On three identical 13x19 prints
made at the same time one print is fine, one shows light banding
across the entire print, and a third has severe banding across half
of the print and the other half is fine.

The problem then disappeared for a while. In the last few days I've
been making a lot of grayscale tests to do some calibration.
Yesterday I made a small test print in the morning that had
significant banding but only above 50% Grey. The gray patches were
arranged on the sheet such that the banding should have crossed all
shades of gray but the banding was only at 50% and above, seeming to
make dark gray the culprit. The same print made this morning is fine.

Is this normal banding? The only previous banding experience I've had
it was there all the time.
