Automatic file system check
When you turn on the printer, you will occasionally see a front panel display similar to the one shown
below.
A file system check is taking place; it can take up to 40 minutes. Please wait until it finishes.
CAUTION:If you turn the printer off before the file system check has finished, the file system could be
seriously damaged, making the printers hard disk unusable. In any case, the file system check will
restart from the beginning whenever you turn the printer on again.
A file system check is scheduled every 90 days, in order to maintain the hard disks file system
integrity.
194 Chapter 19   Troubleshooting general printer issues ENWW
 
						

							NOTE:When the printer is powered back on, it takes about three minutes to initialize and check and
prepare the printheads. However, it can take up to 40 under some conditions, for example, when the
printer has not been used for a long period of time and requires more time to prepare the printheads.
Alerts
Your printer can communicate two types of alerts:
●Errors: Mainly alerting you to the fact that the printer is unable to work normally. However, in the
printer driver, errors can also alert you to conditions that could ruin the print, such as clipping,
even if the printer is able to print.
●Warnings: Alert you when the printer needs attention either for an adjustment, such as a
calibration or for a possible unprintable situation, such as a preventive maintenance or low ink.
There are four different alerts communicators within your printers system.
●Front-panel display: The front panel shows only the most relevant alert at a time. In the case of
a warning, it disappears after a timeout. There are permanent alerts, such as ink cartridge low on
ink, that reappear when the printer becomes idle and there is not another more severe alert.
TIP:From the front panel display you can configure paper mismatch alerts, see Paper suitability
options (T1300 series) on page 26.
●Embedded Web Server: The upper-right corner of the Embedded Web Server window shows
the printer status. If there is an alert in the printer, the status shows the alert text.
●Driver: The driver shows alerts. The driver warns about job configuration settings that may
produce a problem in the final output. If the printer is not ready to print, it displays a warning.
●HP Utility: To see alerts, go to the Overview tab and review the Items needing attention
list on the right-hand side.
By default, alerts are displayed only when you are printing. If alerts are enabled and there is a
problem that prevents a job from completing, you see a pop-up window, which explains the
reason for the problem. Follow the instructions to achieve your required result.
NOTE:There are environments that do not support bidirectional communication, for example: a
Windows computer connected to the printer with USB. In those cases, alerts do not reach the job
owner.
