HP Designjet L25500 Printer Series - Maintenance and troubleshooting guide (second edition)

The printer is not printing
Possible reasons why a file you have sent from your computer is not printing when expected, include the
following:
●
There may be a problem with the electrical power. If the printer is not performing and the front panel
does not respond, check that the power switch at the rear is on, the residual current circuit breakers are
up, the power cable is correctly connected, and the electrical socket is providing power.
●
Unusual electromagnetic phenomena may exist, such as strong electromagnetic fields or severe
electrical disturbances. Such occurrences can cause the printer to behave strangely, or even stop
working. Turn off the printer by using the Power button on the front panel, wait until the
electromagnetic environment has returned to normal, then turn the printer on again. If the problems
persist, call your service representative.
●
One of the following substrate scenarios may exist:
◦
The substrate name that appears on the front panel does not reflect the substrate that is loaded in
the printer.
◦
There is not a sufficient amount of substrate on the loaded roll to print the entire job.
Under these conditions, one print job might be printed, while another print job is held in the print queue.
To resolve this issue, unload the roll from the printer and load a new roll, using the front panel to guide
you through the process.
The software program slows down or stalls while generating the
print job
Large quantities of data might be necessary to generate a high-quality large-format print job. This can cause
your software program to slow down significantly or stall. Lowering the print resolution may help to avoid
this scenario, however, lowering the print resolution reduces image quality.
The printer seems slow
Here are some possible explanations.
●
If you request the highest possible print quality in the RIP, printing will be relatively slow compared with
draft-quality printing.
●
Check that the substrate loaded in the printer belongs to the substrate family that appears on the front
panel.
●
Is your printer connected to a network? Check that all components used in the network (network
interface cards, hubs, routers, switches, and cables) are capable of high-speed operation. Is there a lot
of traffic from other devices on the network?
●
Are the printheads in good condition? Printing time tends to increase when a printhead needs cleaning.
Check the printhead status on the front panel or through the Embedded Web Server. Clean or replace
printheads if necessary.
●
Does your image contain high-density black fills? That may increase printing time.

Cannot access files on the hard disk
If you have trouble accessing files on the printer's hard disk, consider running a file system check. See Check
the file system on page 7.
