You can continue printing - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 28
tips to consider: ● Try selecting a higher print-quality option in your RIP software. ● Check that your printer firmware is up to date. See Firmware update on page 9. ● Check that you have the correct settings in your software program. ● Call your service representative. See When you need help on - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 29
5 Troubleshoot print-quality issues General advice Use the following approach when you have any print-quality problem: ● To achieve the best performance from your printer, use only genuine HP supplies and accessories, whose reliability and performance have been thoroughly tested to give trouble-free - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 30
more passes. ◦ Lower the ink quantity. If the problem persists, call your service representative. See When you need help on page 46. Horizontal banding Try the following remedies if your printed image suffers from added horizontal lines as shown (the color may vary). Troubleshoot images ● If bands - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 31
16). If the problem persists, clean them again. ◦ If the problem persists, try aligning the printheads (see Align the printheads on page 10). If necessary, try aligning them manually. ◦ If the problem persists, print the printhead status plot again. Identify the printhead with the greatest number of - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 32
a long time, or if there has been a substrate jam. Align the printheads if necessary (see Align the printheads on page 10). You can check whether it is necessary by using the printhead status plot (see Use the printhead status plot on page 21). 26 Chapter 5 Troubleshoot print-quality issues ENWW - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 33
(if you disable the substrate-advance sensor, less than 7%) The framing problem may be solved by printing a sample and adjusting the length of the image in the RIP. You may reuse this value for all your future prints with the same substrate, although special care Troubleshoot images ENWW Lack of - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 34
amounts of ink. If this is not possible, print the areas with different amounts of ink as different jobs and modify the length of the job with less ink in the RIP to match its length with the job with high ink content.

If you are trying to load a very thin or very thick substrate, remember to follow the special procedure described in the User's guide for loading such substrates. Check the substrate path ● This - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 36
, then also switch off the power switch at the rear. 2. Wait for the printer to cool down, then unlock and open the printer window. 3. Try to move the printhead carriage out of the way. 4. Lift the substrate-adjustment lever as far up as it will go. 30 Chapter 6 Troubleshoot substrate issues ENWW - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 37
, it can often be cleared by loading a rigid substrate type into the printer. 11. If you find that you have print-quality problems after a jam, try realigning the printheads. See Align the printheads on page 10. Avoiding substrate jams Substrate jams may be caused by loading the substrate with - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 38
to end up on the floor. If the printer recognizes a problem with the take-up reel, it interrupts the print job until the issue is corrected. If the printer does not recognize a problem, the job continues to print. The following table highlights possible issues and solutions.

This ensures that there is fresh ink in the nozzles and helps to prevents nozzle clogs. 34 Chapter 7 Troubleshoot ink-system issues ENWW - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 41
Troubleshoot ink If you have printed the printhead status plot, you know which colors are failing. Clean the pair of printheads that are not performing adequately. If you are not sure which printheads to clean, clean all of the printheads. To clean the printheads, go to the printer's front panel - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 42

NOTE: A calibration image is printed during the printhead alignment process. The front panel shows if there were any errors in - HP Designjet L25500 | HP Designjet L25500 Printer Series - Maintenance and troub - Page 43
. Repeat the alignment process with the printer window closed. If the problem persists after following the recommended remedies, try replacing all of the printheads. If the problem persists after replacing the printheads, a failure in the scanning system may exist.
