POST Soft Fault Messages
When POST detects a soft error, the printer continues the startup process. Before
the printer reaches Ready state, the Startup page is printed with soft errors
appearing in a red box. The box contains all soft faults encountered, with the
upper left corner of the box in the center of the Startup page, and extending to the
right margin, similar to the one shown here.
