My HP Officejet Pro 6230 printer has stopped printing blue.

[ian91]

No error messages.  The test page does not show any blue ink.  Of course I have checked that cartridge is full and I performed the "cleaning" cycle recommended on the Embedded Web Server.

Welcome to HP support community.

Make sure that the cartridges are properly vented and seated correctly

1. Press the Power button to turn on the printer, if it is not already turned on.

2. Open the cartridge access door. The carriage moves to the center of the printer. Wait until the carriage is idle and silent before you continue.
