The tools you need

Building on years of applications experience, QEA has developed a comprehensive line of tools for evaluating EP printer components and sub-systems. These non-contact, non-destructive tools emulate the EP printing process and give you reliable, quantitative data. QEA tools are ideal for:

  • Objective component and sub-system evaluation
  • Process monitoring and control
  • Quality control and quality assurance
  • R&D

Easy to use

QEA control software makes your job easier.

  • MS Windows® for PC platform
  • Easy-to-use interface
  • User-controlled test parameters
  • Test data uploadable to Excel or Access

The bottom line

QEA measurement systems fit a variety of budgets and technical requirements.

Drum evaluation: OPCs and other photoreceptors

Our PDT® products offer state-of-the-art component characterization, including defect mapping and coating-uniformity mapping. PDT® systems mimic the EP printing environment to provide reliable, quantitative data. Each PDT® product scans multiple drum types and sizes. Built-in test functions measure all critical performance criteria, including:

  • Charge acceptance
  • Discharge sensitivity
  • PIDC
  • Residual voltage
  • Cyclic fatigue
  • Coating uniformity
  • Surface defects
Advanced photoreceptor test system with charge roller charging. Used in R&D and production QC of OPC drums. Also used for monitoring primary charge roller (PCR) performance indirectly.

Semi-insulating device evaluation

QEA's test systems for semi-insulating devices emulate the EP printing process to provide reliable, quantitative data. Built-in test functions measure critical performance criteria and include defect mapping and coating-uniformity mapping. Built for efficiency and flexibility, each roller or belt test system scans multiple component models and sizes. These systems provide non-contact, non-destructive characterization of:

  • Charge rollers
  • Development rollers
  • Transfer rollers
  • Magnetic roller sleeves
  • Intermediate transfer belts
  • Paper and other substrates

All in one

In addition to our specialized systems, QEA now offers the DRA-2000L, a general-purpose system for testing all semi-insulating rollers and belts.
