Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own personal safety.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.

NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not covered by your warranty.

NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such as a connector on the back of the computer).

NOTICE: To help prevent damage to the computer, perform the following steps before you begin working inside the computer.

1Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.

2Turn off your computer (see "Turning Off Your Computer" on page 137).

NOTICE: To disconnect a network cable, first unplug the cable from your computer, and then unplug it from the network wall jack.

3Disconnect any telephone or network cables from the computer.

4Disconnect your computer and all attached devices from their electrical outlets.

NOTICE: To help prevent damage to the system board, you must remove the battery from the battery bay before you service the computer.

NOTE: To avoid damage to the computer, use only the battery designed for this particular Dell computer. Do not use batteries designed for other Dell computers.

The Dell 1720 is designed with performance in mind, boasting a print speed of up to 33 pages per minute, making it ideal for high-volume printing environments. Equipped with a 400 MHz processor and 64 MB of memory, it ensures fast processing of complex documents, thereby reducing wait times for users. Its maximum print resolution of 1200 x 1200 dpi guarantees crisp, clear text and sharp graphics, suitable for professional presentations and reports.

On the other hand, the Dell 1520, while slightly less powerful, still offers impressive capabilities.

The compact design of the 1520 makes it a great option for businesses with limited space, while still maintaining robust performance standards.

Both printers utilize Dell's proprietary Toner Management System, which helps monitor toner levels and notifies users when it's time to order replacements. This technology aids in minimizing downtime and ensures continued productivity. The printers are compatible with a variety of operating systems including Windows and Mac OS, making them versatile solutions for diverse office environments.

Another important feature of the Dell 1720 and 1520 is their energy efficiency, thanks to Energy Star certification. This ensures that both models consume less power compared to traditional printers, making them eco-friendly choices for businesses looking to reduce their carbon footprint.

In terms of connectivity, both models come equipped with USB 2.0 ports for straightforward connections to computers. Additionally, the Dell 1720 offers optional networking capabilities with an Ethernet port, allowing for sharing across multiple users in a networked environment.
