● Reseat: You are recommended to remove the printhead and then reinsert it. If that fails, clean the electrical
connections (see Clean the electrical connections on a printhead on page 144). If that fails, replace the
printhead with a new printhead (see Replace a printhead on page 137).
● Replace: The printhead is failing. Replace the printhead with a working printhead (see Replace a printhead
on page 137).
16 Chapter 1 Introduction ENWW
● Replacement incomplete: The printhead replacement process has not completed successfully; restart the
replacement process and let it nish completely.
● Remove: The printhead is not a suitable type for use with your printer.
● Non-HP ink: Ink from a used, relled, or counterfeit ink cartridge has passed through the printhead. See the
limited warranty document provided with your printer for details of the warranty implications.
You can also use the Embedded Web Server to check the printhead status and the warranty status. See Access
the Embedded Web Server on page 23.
Check the le system
It is possible to check the integrity of the le system on the printer's hard disk, and automatically correct any
errors. You are recommended to do this about once every six months, or if you notice any trouble in accessing
les on the hard disk.
To execute the le system check, go to the front panel and press , then Preventive maint. tasks > File
system check.
If the printer is aware of damage to the le system, for instance after a severe software problem, it may start a
le system check automatically. This can take about ten minutes.
Printer alerts
The printer can communicate two types of alerts:
● Errors: When the printer is unable to print.
● Warnings: When the printer needs attention for an adjustment, such as a calibration, preventive
maintenance, or ink cartridge replacement.
● Advice: When a rmware update is available or the downloaded rmware is ready to be installed.
Printer alerts appear in the front panel and in the Embedded Web Server.
● Front-panel display: The front panel shows the alerts in the upper left part of the screen (notication bar).
Only one alert is shown at a time. If you press the notication bar, all the current printer alerts are shown.
The list of alerts can be folded back by pressing or sliding up the bottom row of the list.

An alert may require you to perform a maintenance operation; see Hardware maintenance on page 129.
The following alerts require a service engineer:
● Service Maintenance Kit 1
● Service Maintenance Kit 2
● Service Maintenance Kit 3
Printer states
The printer may be in any one of the following states; some of them require waiting.
● Ready (cold): The printer is powered on but has not printed yet, and the heaters are not turned on.
● Preparing to print: The printer is warming up the heaters and preparing the printheads to print. This takes 1
Clicking an alert opens the application that could help to resolve it. Firmware update advice is dismissed

● Ready for substrate
● Ready for side A/B
● Printing
● Printing side A/B
● Drying: This takes 1.5 to 5 min.
● Finishing: The printer is cooling down and preparing for stand-by. This takes 0.5 to 5 min.
You can select continuous printing using certied RIP software. Without continuous printing, the printer cures
each job separately and then winds the substrate back into the print zone before starting to print the next job in
the queue. This adds time to the printing process. Continuous printing saves time by continuing to print the next
job in the queue without stopping (tailgating), if it uses the same print mode and resolution.
NOTE: The same print mode and resolution must be used for all jobs in the RIP queue selected for continuous
printing, to optimize the overall curing time.
NOTE: When continuous printing is enabled, canceling a job could also cancel the subsequent job.
18 Chapter 1 Introduction ENWW
Change margins
The printer margins determine the area between the edges of your image and the edges of the substrate. The
365 or 375 printer with ink collector is capable of printing with no side margins (full bleed).
The side margins for a particular print job are selected in the RIP software; if the job exceeds the substrate width,
it will be clipped.
The front panel oers additional settings for the top and bottom margins: see Margins on page 175. These
settings apply only to single prints when the cutter is not in use. The top and bottom margins are not applied
during double-sided printing.
To set the top margin at the front panel, press , then Substrate > Substrate handling options > Extra top
margin.
To set the bottom margin at the front panel, press , then Substrate > Substrate handling options > Extra
bottom margin.
NOTE: The extra top/bottom margin set in the front panel is applied in addition to the top/bottom margin
selected in the RIP.
NOTE: The side margins can be adjusted in the RIP.
Request the printer’s internal prints
The internal prints provide various kinds of information about your printer. Request these prints from the front
panel, without using a computer.
Before requesting any internal print, make sure that substrate is loaded and that the Ready message appears on
the front-panel display.
To print an internal print, press , then Setup > Internal prints, then select the type of internal print that you
want.
The following internal prints are available:
● Usage report: Shows estimates of the total number of prints, number of prints by substrate family, number
of prints by print-quality option, and total amount of ink used per color. The accuracy of these estimates is
not guaranteed.
● Service information: Provides information that service engineers require.
Check lifetime usage statistics
There are two ways of checking your printer's usage statistics.
NOTE: The accuracy of the usage statistics is not guaranteed.
● From the Embedded Web Server, go to the Main tab and select History > Usage. See Embedded Web Server
on page 22.
● From the front panel, press , then Setup > Internal prints > User information prints > Print usage
report.

HP Latex Mobile
Your printer supports a new application called HP Latex Mobile, which marks a new era of smart printers. This
app enables you to receive helpful consumables alerts while remotely monitoring your printer and job status on
your smartphone or tablet. It also compiles metrics related to ink and substrate usage and productivity that you
can view from your tablet. Print with greater condence, especially as you no longer have to worry about the
status of print jobs while you’re away from the printer.
NOTE: HP Latex Mobile is compatible with Android 4.1.2 or later and iOS 7 or later, and requires the printer and
the smartphone or tablet to be connected to the Internet.
NOTE: Metrics are available on tablets but not on smartphones.
Rely on alerts to tell you when attention is needed
No more wondering what’s going on with your printer while you’re away:
● Alerts keep you informed about supplies, the substrate path, and situations when the printer is not ready.
● Return to your printer and take action once you’ve been alerted.
Know the status of your printer while you’re away from it
HP Latex Mobile oers insight into printer activity and ink and substrate usage:
● Follow printer activity remotely and gain an awareness of your printer at all times.
● Stay abreast of ink levels and the amount of substrate remaining to avoid surprises and respond
accordingly.
● Use your tablet to view metrics. Email that information to your computer for more details of ink and
substrate usage as well as productivity per printer or job. Use it to improve planning and operations.
20 Chapter 1 Introduction ENWW
Remotely keep tabs on print jobs
HP Latex Mobile enables you to monitor job completion and job history:
● Track print jobs through to completion.
NOTE: Printer updates occur roughly every ve minutes during the printing process and every several
hours when the printer is idle. Under certain circumstances, printer updates may be delayed—when system
errors occur, for certain substrate jams, in the case of a power outage—in which case the app dashboard
display shows the last known printer status.
