  • Figure 11 is a magnified view of part of the example cartridge.
  • Print liquid is a fluid for printing.
  • Examples of print liquid include ink and fusing agent.
  • accurately sensing an amount of print liquid remaining in a reservoir may be difficult due to issues like liquid bridging, environmental conditions, and water vapor transmission rates. An inaccurately sensed liquid level may lead to changing the reservoir more often than necessary, wasting print liquid, and/or increasing printing expense. Accordingly, it may be beneficial to provide more delivered print liquid, a more reliable sensed print liquid level, and/or less ink supply changes.
  • a sensor or sensors may be utilized to increase print liquid level sensing accuracy.
  • the sensor(s) may be housed in a print liquid supply unit.
  • a print liquid supply unit is a container that holds print liquid.
  • a print liquid supply unit may be referred to as a print liquid container, a cartridge, a supply, print liquid supply cartridge, etc.
  • the print liquid may be supplied to a printer.
  • four print liquid supplies may be utilized for a printer, which may include black, cyan, magenta, and yellow print liquid supplies. This may allow print liquid supplies with colors to be replaced individually. For example, a print liquid color that is used more often may be replaced individually without replacing remaining print liquid of another color or colors.
  • print liquid supply units may be constructed of thermoplastics.
  • Thermoplastics may be injection molded and may be compatible with high volume manufacturing and/or assembly methods. It may be beneficial for the construction materials (e.g., materials to construct components of the print liquid supply) to be compatible with the print liquid, to be robust to environmental conditions during shipping/handling, and/or to provide target water vapor transmission rates such that print quality is maintained over the life of the print liquid supply unit.
  • print liquid supply units may be constructed from thermoplastics such as polypropylene (PP), low-density polyethylene (LDPE), high-density polyethylene (FIDPE), polyethylene terephthalate (PET), polycarbonate (PC), and/or blends thereof.
  • thermoplastics may be compatible with high volume assembly methods such as ultrasonic welding, vibration welding, and/or laser welding.

  • “welding,”“weld,” and variations thereof may denote laser welding, ultrasonic welding, and/or vibration welding.
  • Other approaches for joining components may be excluded from the term“welding” (and variations thereof) in some examples.
  • Welding may be beneficial because plastic parts may be joined via high speed melting.
  • welding may not include utilizing another bonding agent or additional parts. Issues may arise when attempting to pass an electrical connection through a welded joint.
  • a sensor may be housed in a print liquid supply unit and may utilize a conductor that passes through a welded joint.

  • a clamp may be applied to the first housing component 102 while the second housing component 104 is supported.
  • a laser beam may be passed through the first housing component 102 to the underlying supply joint 106 geometry below.
  • the second housing component 104 may absorb a portion (e.g., a majority) of the energy, which may cause the material of the second housing component 104 (along the supply joint 106, for example) to melt.
  • the pressure and phase change of the material may cause the first housing component 102 to join to the second housing component 104.
  • the print liquid supply unit 100 may collapse slightly, which may cause the material along the supply joint 106 to widen.
