Digital BW, The Print

Looking for help. I have a 1270 w/ a cis. Nozzle checks were showing
clogs. Moved the cartridge assembly to the left. Lifted it out and
wiped bottom of cartridges. Now I'm getting almost no ink flowing
thru cis tubes into carts. Nozzle checks are poor. Cleaning cycles
don't help. There doesn't seem to be any ink flow from the ink
bottles into the tubes that flow to the carts.

If you have had experience with this type of problem please reply.

Thanks,
Mike
