The tools you need
Drawing on years of applications experience, QEA has developed a comprehensive line of tools for evaluating EP printer components and sub-systems. This unique family of test systems embodies innovative engineering solutions and a fundamental understanding of the physics of EP processes to give you “must-have” tools for high-speed printer R&D and quality control. These non-contact, non-destructive tools emulate the EP printing process and deliver quantitative data you can rely on. 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

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.
