Empty ink cartridge - Wallpen E1+

Empty ink pouch – Wallpen E1+

The Wallpen empty ink pouch is the flexible reservoir integrated into the ink supply system of the Wallpen E1+ wall plotter. It stores CMYK UV ink before it is fed to the Drop-on-Demand (DOD) print heads.

Supplied empty, the pouch is designed to be filled via the refill port on the print head assembly, using 200 ml Wallpen UV ink bottles. Its flexible design ensures a supply without unwanted back pressure, which is essential for the stability of the ink jet when the printer is in a vertical position on the wall.

A genuine Wallpen part, it replaces a worn, punctured or contaminated reservoir in the wall printer’s ink circuit, without the need for major work on the robot frame.

• Replace an existing bag at the end of its service life without completely draining the machine

Possible symptoms of wear

• Ink leakage under the print head assembly or in the carriage housing
• Drop in supply pressure and appearance of print gaps
