PoS Label Printer

Background

The paper loading to the printer was taking more time consuming procedure in field

Solution

To facilitate easy paper insertion Top plate was cut to and experimented without top support for hinge.

Observation

Observation after top plate is cut

  • Printer door is not stable, and topples down when opened Top portion in the print is light
  • Print quality deteriorates
  • Holding the hinge pin manually is improving the print

Inference

The top end of the hinge should be supported for proper print quality

Highlights

4 Concepts were created to support the hinge

Concept 1 – Simple Bend Bracket

The top end of hinge is supported by simple bracket. Bracket is aligned to Base with Locating features on the Base

As part of the Design validation, iSol also carried out a drop test and confirmed the product would be safe upon accidental drop from 3 feet to the ground

Concept 2 – Machined blocks with simple sheet metal bracket

The top end of hinge is supported by gooseneck bracket. Alignment of the bracket is maintained by Locating pins in the plastic base

Concept 3 – Hinge supported directly in the bas

Bottom end of the hinge is supported in the base. Top end is secured by circlip

Concept 4 – Hinge and Hook

Top end of the hinge was connected by a Hook. The user has to slide open and close the Latch while replacing paper roll
