FCC compliance

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy. If it is not installed and used in accordance with the instructions, it may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or tele vision reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase separation between equipment and receiver.

• Connect equipment to an outlet on a circuit different from that to which the receiver is located.

• Consult your dealer or an experienced radio/TV technician.

Guidelines for energy efficiency.

Toner consumption

EconoMode uses significantly less toner, which may extend the life of the toner cartridge.

Paper use

Depending on the type of software program in use, y ou can request for a n umber of pages of your document to be printed on one page of paper. This N-up printing practice and the printer’s manual duplexing feature, which provides two-sided printing, can reduce paper usage and the resulting demands on natural resources.

Environmental Product Stewardship Program

The design of this HP LaserJet printer facilitates the recycling of:

Plastics

Plastic housing parts have markings according to international standards that enhance the ability to identify plastics for recycling purposes at the end of the printer’s life.

HP LaserJet printing supplies

In many countries, this product's printing supplies (e.g., toner cartridge, drum, fuser) can be returned to HP through the HP Planet Partners Printing Supplies Environmental Program. An easy-to-use takeback component of the program is available in over 20 countries. Multilingual program information and instructions are included in every new HP LaserJet Toner Cartridge and Consumables box.

HP Planet Partners printing supplies environmental program information

Since 1990, the HP LaserJet Toner Cartridge Recycling Program has collected more than 12 million used HP LaserJet toner cartridges that otherwise may have been discarded in the world's landfills. The HP LaserJet toner cartridges go to a collection center and are bulk shipped to our recycling partners who disassemble the cartridge parts for recycling. After a thorough quality inspection, minor parts such as nuts, screws, and clips are reclaimed for use in new cartridges. Remaining materials are separated and converted into raw materials for use by other industries to make a variety of useful products.

HP LaserJet 1100 Printer control panel

Hardware overview

The HP LaserJet 1100 Printer’s Control Panel consists of tw o LEDs and a Go ke y containing a third LED. There is one amber LED (the Attention LED), and two green LEDs (the Ready LED and the Go LED). The green LEDs are contained in the Go key. If the scanner is attached, there are two additional buttons. Scanner modes are not shown on the printer LEDs and scan keys have no effect on printer functionality.

Go key

The HP LaserJet 1100 Printer Control Panel’ s single Go k e y will be the only means the user has of interacting with the printer, except through software. Therefore, the Go key must perform all actions the user needs. The Go key performs ten functions. These functions are explained in the table below. See “Scanner control panel” on page 31.

Normal printer operation

When power is supplied to the printer, all LEDs go on and then off. The LEDs will sequence on and off, one after the other, from the first LED (Go key/LED) to the last LED (Attention LED). If an error is detected or if paper is out, the printer will enter that error mode.

When data is downloaded to the printer (during Ready mode), the Ready LED will blink. When the printer stops receiving data, the Ready LED may continue to blink while the printer formats the data.

If an error occurs, the printer will enter that error mode and display the error on the Control Panel.

Error priority

The highest priority error will be displayed if multiple errors occur simultaneously. The priority of errors, from highest priority (most important) to lowest, is:

1 Fatal Errors 2 Door Open/No Toner Cartridge 3 Paper Jam 4 Paper Out 5 Memory Error

While in any of the errors except Fatal Error, a reset may be performed by pressing and holding the Go key for fiv e or more seconds, or unplug to reset. When the reset completes it will return to the error condition. If the error was cleared by the reset (such as a Memory Error), the printer will return to Ready mode.

Scanner control panel

Figure 2-2 Scanner control panel

The scanner Control Panel consists of two keys; a scan key and a copy key. These keys have no effect on the printer other than contention for resources.

Scan

NOTE:

Pressing the scan key sends a message to the computer that opens the appropriate software application to start the scan or starts a scan depending on how the computer software is configured. If the scan is initiated with no paper in the ADF, an error message will appear on the computer.

Quick copy

Pressing the copy button initiates a scan that is sent directly to the printer without using the computer software. If there is no paper in the ADF, the scanner will still attempt to pick up a sheet of paper. The Quick Copy function will work even if the unit is not attached to a computer.

Scan Abort: Pressing both copy and scan keys within one half second of each other causes the scanner to abort the current scan. If there is paper in the scanner, the scan engine will be in a jam mode, and the paper will have to be removed manually. This decreases the chance of documents being damaged by the scanner.

Scanner key functionality based on printer status

The following table contains scanner and printer modes and the result of pressing the scan and/or copy keys. The scanner key has no effect on printer functionality other than some print functionality will be held off due to contention for resources. The only print key press that will affect a scan job, other than contention for resources, is a printer Control Panel reset.
