Status Indications for both A776 printers
The on-line, paper status, error light is the light to the
rear, on the top edge of the printer. It may be the first
indication that something is wrong.
The light closer to the front on the right edge of the
printer indicates that a form is inserted properly. It does
not indicate an error.
For some unexpected conditions, the printer
communicates the information to the host computer
and relies on the application to tell the user that the
printer has a problem.
The following pages describe common conditions that
you could encounter and easily fix yourself. A few may
require that you contact a service representative. See
“Contacting a service representative” on page 46.
