These 2 colors are not printing (or printing slightly) The ink systems are good and under the proper pressures.
If there is a potential electrical issue causing this, does anyone have any suggestions on which boards to check or replace? Fuses to look at?
I'm stumped.
Thanks,

Hi
often problem with printheads (if not defective printheads) - not contacting well inside the carriage - gold plated contacts must be cleaned with alcohol and the contacts of the carriage must be cleaned too. Before first installing, printheads must be shaken well. Other problem - not very well seaten inside carriage...
Cheers
