Questions
OverviewOverview
SummarySummary
• Oil is transferred from the maintenance roller to the drum before ink is transferred by the print head
• Ink transfer from drum to paper as the paper feeds between the transfix roller and drum
• Objective: produce a imaging system that is capable of capturing ink drops on the drum of a solid ink printer and on the paper
• The imaging systems will be used by Xerox, Portland State Undergraduate and Graduate students for research of the solid-ink printing process.
• There is no specific imaging system that compares the drum images to paper images
SummarySummary
Previous SystemPrevious System
• Clumsy to use• Vibrates excessively• Optical system does not meet desired image quality

DODVS Final Frame DesignDODVS Final Frame Design
DODVS FrameDODVS Frame
• Uses 3x6 inch T-Slot vertical supports
• 3/4 inch thick aluminum base and top plate
• Added gussets increase natural frequency and decrease amplitude of oscillation
• Previous system was heavy and cumbersome

Vibration TestingVibration Testing
• ANSYS simulation was verified using strain gage analysis
• Same 3x6 inch T-Slot material
• Same 3/4 inch thick base and top plate
• Features cover plates to hide messy electronics and wires
• Very similar to DODVS construction
BTM Frame DesignBTM Frame Design
BTM AutomationBTM Automation
• The BTM uses a stationary camera • X-Y Stage donated by Xerox
BTM AutomationBTM Automation
• Stage can be controlled electronically by the joystick control interface
• Hand-cranks added for finer adjustments
• Existing camera and optic components reused to reduce cost
• An identical camera and optics purchased for BTM
• New optics system has magnification range 3x to 22x
