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.
NOTE: Any changes or modifications to the printer that are not expressly approved b y HP could void
the user’s authority to operate this equipment.
Use of a shielded interface cable is required to comply with the Class B limits of Part 15 of
FCC rules.

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. For more information in the
U.S., call 1-800-340-2445 or visit the HP LaserJet Supplies website at:

Laser safety statement
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug
Administration has implemented regulations for laser products manuf actured since August 1,
1976. Compliance is mandatory for products marketed in the United States. The printer is
certified as a “Class 1” laser product under the U.S. Department of Health and Human
Services (DHHS) Radiation Performance Standard according to the Radiation Control for
Health and Safety Act of 1968.
Since radiation emitted inside the printer is completely confined within protective housings
and external covers, the laser beam cannot escape during any phase of normal user
operation.
WARNING! Using controls, making adjustments, or performing procedures other than those specified in

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.

while data is in the printer, a form feed pending will occur. Once the data the printer has
received is completely formatted and no more data is in the I/O, the partial page will be

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

The highest priority error will be displayed if multiple errors occur simultaneously. The

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.
