If you use a substrate that is too porous, or fail to clean the platen as recommended, you could experience a decrease in print quality that would require a service repair not covered by your warranty.

Do not insert your fingers into the spindle supports during the removal process. The spindle has a stop at each end - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 29
5. Remove the stop from the left end of the spindle. 6. Rest the roll of substrate that you want to load on the loading table. If the roll is long and heavy, you may need two people to handle it. 7. Slide the spindle into the roll. Handle the substrate ENWW Load a roll onto the spindle 25 - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 30

TIP: If the cardboard core of the substrate is longer than the substrate, you can load the substrate without inserting the blue stop, but - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 31
loading very thin or very thick substrates, or substrates with a tendency to curl, you should follow the manual loading procedure to reduce the risk of substrate jams and printhead crashes; see Load a roll into the printer (manually) on page 30. 1.

Load a roll into the printer (manually) The manual loading process should be used in the following cases: ● The substrate is unusually thin or unusually thick. ● The substrate has ragged edges. ● The substrate tends to curl at the edges. ● The printing side of the substrate faces outwards. In other - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 35

There are two different loop-shapers provided with the printer, to be used with different substrate types. ● The heavy loop-shaper is used with banner, textile and mesh substrates. It is attached to supports on either side of the substrate. The spindle stops should not be used with this loop-shaper - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 39
is used with all other substrates. It lies in the substrate loop, supported only by the substrate, unattached at either end. It should be the same width as the substrate; therefore, it is supplied in sections of different widths that can be fitted together. The spindle stops should be used with - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 40

Tape the leading edge of the substrate to the core in the center, then at each side. Make sure that the - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 43
14. Press the blue arrow on the take-up reel motor to rotate the spindle one full turn. This will help to support the weight of the loop-shaper. 15. Gently lower the loading table, to avoid wrinkles and improve winding. 16. Carefully insert the heavy loop-shaper. - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 44
17. Fit the loop-shaper into the supports at either side. 18. Use the wind-direction switch on the take-up reel motor to select the winding direction. Setting 1 winds the substrate so that the printed image faces in. Setting 2 winds the substrate so that the printed image faces out.

may wrinkle on the platen, causing vertical banding, ink smears or substrate jams. Curing is needed to coalesce the latex, creating a polymeric film which acts as a protective layer, while at the same time removing the remaining co-solvents from the print. Curing is vital to ensure the durability - HP Designjet L26500 | HP Designjet L26500 Printer series - User's Guide - Page 66
to the substrate at the printing zone helps to hold the substrate down on the print platen, keeping the distance to the printheads constant.
