User Guide for HP Latex 126-in Roll-to-Freefall Kit

Quick guide from the manual

The HP Latex 126-in Roll-to-Freefall Kit is an accessory designed to enhance printer productivity by allowing the finishing process to start on one print while the next is being printed. It is compatible with the HP Latex 1500 Printer and the HP Latex 2700/FS50/FS60 printer series.

Substrate configurations

Before loading, access the Internal Print Server and select the desired configuration under Substrate load/unload.

Roll-to-freefall configuration

This mode allows you to cut and remove prints immediately after they exit the printer. The substrate is kept under tension between the input roll and the tension roller.

• Ensure the tension roller lever is raised.
• Unlatch the tension roller at both ends.
• Move the roller to the front to pass the substrate behind it.
• Pass the substrate through, then push the roller backwards.
• Close the latches at both sides.
• Align the substrate edge using the rulers on the spindle and tension roller.
• Ensure the substrate is evenly tensioned and flat, then close the tension roller lever.
• Click the Finish button on the Internal Print Server.

Roll-to-collector configuration

This mode uses a collector roller and tension bar for winding.

• Select a tension bar of the correct length to match the substrate width using the supplied tubes.
• Follow the roll-to-freefall loading procedure first.
• Load an empty substrate core onto the output spindle.
• Advance the substrate leading edge to the core on the collector.
• Attach the leading edge to the core with tape, ensuring no wrinkles.
• Advance the substrate to create a loop between the tension roller and the collector.
• Place the tension bar into the substrate loop.
• Click Enable collector (HP Latex 1500) or Take-up reel (HP Latex 2700/FS50/FS60) on the Internal Print Server.
• Select winding direction (Outwards is recommended for rolls up to 300mm).

Hardware maintenance

Clean the roll-to-freefall roller and pinchwheels when they are visibly dirty or if substrate advance is not smooth.

• Preparation: Ensure the printer is not printing, unload the substrate, and raise the pressure roller lever.
• Cleaning the roller: Use a clean cloth dampened with water (isopropyl alcohol for persistent dirt). Turn the roller manually to clean the entire rubber surface. Ensure parts are dry before use.
• Cleaning pinchwheels: Open roller latches, move the roller to the front, and lower the pressure roller lever to access the pinchwheels. Clean carefully with a damp cloth.

Diagnostics and troubleshooting

The Internal Print Server provides specific diagnostic tests for the kit, including electronic checks, sensor status checks, and motor tests. If an error code appears, follow the specific recommendations for your printer model (HP Latex 1500 or HP Latex 2700/FS50/FS60 series). Common issues involve sensor jams, fuse failures, or latch/lever status errors. Always ensure sensors are free of obstructions and cables are properly connected.
