HP Hybrid POS Printer with MICR II Uživatelský manuál stáhnout pdf (Strana 38)

A Troubleshooting

Because of the design of the printer, it requires virtually no periodic servicing. However, if problems do occur,

they can usually be diagnosed readily by checking the light status indicators, below, then referring to

appropriate sections in this appendix.

Status indicators

The online paper status error light is the light to the rear, on the top edge of the printer. It may be the rst

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 POS computer and relies

on the application to tell the user that the printer has a problem.
