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

Clean and lubricate the carriage rail
NOTE: Under some workflows, or/and site conditions such as in warm ambient temperature, which are
above the printer's operation specification (above 30ºC(86ºF)), or if there is significant ambient dust; the
lubrication of the slider rods can be reduced or affected, which can in turn affect the performance of the
printer.
NOTE: A visual explanation of the procedure to clean and lubricate the carriage rail can be found here:

1. To gain access to the carriage, go to the front panel and select the icon, then select Carriage rail
lubrication.
2. Unlock and open the window.
3. Clean the carriage rail using a lint-free cloth dampened with Isopropyl alcohol. Take care to clean the
whole rail, including the part under the left cover.
NOTE: Isopropyl alcohol is not provided in the Maintenance Kit.
CAUTION: Isopropyl alcohol is highly flammable. Observe the manufacturer’s safety precautions.
NOTE: If you are in an area (such as California) that regulates VOC cleaning and maintenance fluids,
instead of isopropyl alcohol please use a VOC-certified cleaner such as a properly diluted Simple Green
All-Purpose Cleaner.
CAUTION: Do not use commercial cleaners or abrasive cleaners.
CAUTION: While cleaning, be careful not to damage the metal strip located on top of the rail.
4. Wait until the rail is dry, then close the window. The carriage moves to the center of the printer so that
you can reach the part of the rail under the right cover.
5. Unlock and open the printer window.
