Need help..... This machine is printing very, very slow. The prints all look good, there is no error codes or warning messages. Carriage will print a line in one direction and then pause for a minute or two, as if it is waiting for the ink to dry or something. Then it will print another line and again pause for a minute or two, and continue doing this until the document is finished. It also does this with internal service and test prints, so it is not a driver issue. Nothing in the book remotely linked to this, and no errors in the log to indicate what the problem is. Cleaned and lubed the carriage rails and encoder but no help.

Also, the problem comes and goes. Some days it will print fine, then the next day very slow. Pulling my remaining hair out on this one.
Thought it was fixed last week, but then customer called back yesterday saying it is doing it again
