The Printhead nozzles are clogged. Because the printer was left without ink tanks installed for some time, ink has become clogged in the ink supply system. Paper is jammed inside the Top Cover. The ink was not dry when paper was cut. Printing may be faint if Print Quality in Advanced Settings in the printer driver is set to Standard or Draft. Corrective Action Print on the printing surface. Print a test pattern to check the nozzles and see if they are clogged. (See "Checking for Nozzle Clogging.") →P.973 After the ink tanks have been installed for 24 hours, run Head Cleaning B from the Control Panel. (See "Cleaning the Printhead.") →P.974 Follow the steps below to remove the jammed piece of paper inside the Top Cover. 1. Open the Top Cover and make sure the Carriage is not over the Platen. 2. Remove any scraps of paper inside the Top Cover. (See "Clearing Jammed Roll Paper.") →P.1006 (See "Clearing a Jammed Sheet, Fed Manually.") →P.1010 3. Close the Top Cover. Specify a longer drying period in the Control Panel menu, in Paper Details > Roll DryingTime.
