Operational Precautions

Operational Precautions

Note the following important precautions whenever using the printer.

Operating Environment

The following describes the operating environment required when using the printer.

Temperature:

10°C to 35°C (50°F to 95°F) with fluctuation of 10°C (18°F) per hour

Humidity:

15% to 85% with fluctuation of 20% per hour

Printer

The following describes precautions for using the printer.

Never turn the printer off or open any of its covers during a print operation.

Never place flammable gasses, liquids or objects that generate mag- netic forces near the printer.

When unplugging the power cord, always grasp the plug and never pull on the cord. A damaged cord creates the danger of fire or elec- trical shock.

Never touch the power cord when your hands are wet. Doing so cre- ates the danger of electrical shock.

Always unplug the power cord before moving the printer. Failure to do so can damage the power cord, creating the danger of fire or electrical shock.

Always unplug the power cord if you do not plan to use the printer for a long time.

Never try to remove any secured panel or cover. The interior of the printer contains high-voltage circuitry which creates the danger of electrical shock when exposed.

1100 specifications

The NEC 1100, introduced in the early 1980s, stands as a significant milestone in the evolution of computing technology. It is widely recognized for its role in pioneering advancements that shaped the landscape of computing during its time.

One of the main features of the NEC 1100 is its architecture. It operates on a 16-bit microprocessor, specifically the NEC 780, which allows for efficient data processing and improved performance over its predecessors. This architectural design provided enhanced functionality, enabling the NEC 1100 to handle complex tasks that were challenging for earlier systems.

The NEC 1100 was equipped with a robust memory capacity, supporting both RAM and ROM configurations. Typically, it featured 64KB of RAM, expandable to accommodate increased processing demands, alongside a ROM that facilitated essential system instructions. This flexibility in memory management underscored its adaptability to various user needs, making it suitable for both personal and business applications.

Furthermore, the NEC 1100 employed advanced input/output (I/O) capabilities, which included multiple ports, enabling easy connectivity with peripherals such as printers, modems, and disk drives. This extensive range of I/O options contributed to its versatility, allowing users to customize their configurations according to specific requirements.

In terms of software, the NEC 1100 supported several operating systems, including Microsoft's MS-DOS and various other compatible systems. This compatibility made it a preferred choice among software developers, fostering a rich ecosystem of applications that could leverage the NEC 1100's capabilities.

One of the notable characteristics of the NEC 1100 is its commitment to reliability and durability. The design emphasized robust engineering, ensuring that the system could withstand continuous usage in various environments, a critical factor for businesses relying on consistent performance.

The NEC 1100 also featured pioneering display technologies, embracing CRT monitors that allowed for crisp visuals and effective graphical outputs. This was a significant advantage at a time when text-based interfaces were the norm, allowing users to engage with graphical applications seamlessly.

In summary, the NEC 1100 is not just a computer; it's a testament to the technological advancements of its era. With its 16-bit architecture, expandable memory, extensive I/O capabilities, and support for various operating systems, it laid the groundwork for future innovations in personal computing. Its reliability and adaptability made it a cornerstone in the transition from basic computing to more complex, user-oriented systems, influencing generations of technology to come.
