This section presents summary lists of recommendations for design issues related to access for persons with disabilities. Item numbers are based on lists in related sections of this appendix.
11. Accessibility for printers
Recommended
Visual Displays and Indicators:
3 Make LCD and LED indicators, warning, and alert lights software-readable.
Sound:
4 Provide a visually distinct indicator for all alerts or warning sounds created by hardware.
5 Provide visual indication of important sounds generated in normal computer operation.
6 Send hardware-generated beeps to the operating system.
9 Reduce noise level of operating internal components.
Manipulation and Physical Design:
1 Eject media a sufficient distance for grasping.
3 Make latches operable with one hand.
4 Minimize force required for inserting and retrieving media.
6 Provide error flags for misinserted media, especially CDs.
7 Ensure that devices do not generate electromagnetic or RF fields that would affect users with hearing aids.
11 Minimize operation noise levels.
12 Eliminate hard edges or sharp corners that could cause injury or inhibit correct device placement.
13 Manufacture outer surfaces using only hypoallergenic materials.
Input and Controls:
1 Allow connection, substitution, or addition of alternative input devices.
2 Design all controls to operate from the keyboard.
3 Mount all controls on the front of the device.
4 Limit button design primarily to push-button controls.
5 Use concave buttons, especially where sustained force is required.
6 Avoid twisting motions.
7 Minimize the force required for operation.
8 Make all controls operable with one hand.
9 Avoid capacitance-based controls.
10 Use functional grouping and layout of controls.
11 Make controls tactually discernible.
12 Make the state of non-momentary controls tactually discernible.
13 Provide tactile and audible actuation feedback for controls.
15 Maximize size of controls within the space available.
16 Space the controls a sufficient distance to allow for tactile and visual discrimination.
20 Remove left-right bias.
Labeling:
1 Use large, high-contrast, bold stroke, sans serif lettering, and avoid using artwork behind text.
2 Use tactually distinct icons for controls, connectors, and legends.
3 Provide optional Braille and tactile labels.
