Safety Warnings
Note: The DEClaser 1100 series printers comply with all United States
government safety regulations applicable to ozone gas emissions and laser beam
light exposure.
Laser Safety: The DEClaser 1100 series printer complies with 21 CFR
Chapter 1, Subchapter J, 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. The
DEClaser 1100 series printers do not emit hazardous light since the laser beam
is totally enclosed during all modes of customer operation and maintenance.
Warning: Use of controls or adjustment procedures other than those specified
in this manual may result in hazardous laser light exposure.

Physical and Functional Description
This chapter provides a physical and functional description of the DEClaser
1100 series printer.
1.1 Description of the DEClaser 1100 Series Printers
The DEClaser 1100 series printers are compact, low-cost, desktop printers
capable of printing high-quality text or graphics at speeds up to 4 pages
per minute on a variety of typical media, including paper, envelopes, and
transparencies. Appendix B contains printer and media specifications.
Media can be fed into the printer from the standard input tray or from an
optional feeder cassette that attaches to the bottom of the printer. The printer
and cassette are customer installable.
A unique feature of this printer is rollers used in place of ozone-producing
charge wires. The operation of the control panel is similar to the DEClaser
2000 series printers.
1.2 Printer Components
Figure 1–1 has numbered callouts to identify the location of the operational
components visible from the right side of the printer. For a description of each
component refer to Table 1–1.

Control panel The control panel has a message display, indicator
lights, and a keypad. See Chapter 2 for additional
information on using the control panel.

Font cartridge slots These two slots accept the optional font or program
cartridges. For example, the PostScript cartridge
is a program cartridge. See Section 2.17 for more
information.
Caution: Before inserting or removing a card, turn
off the printer power. The printer will cease to operate
and damage may occur if the font or program card is
inserted or removed while the printer power is on.

Power switch Powers the printer on or off. To ensure data is not
lost, always be sure the display reads 00 READY or PS
READY/IDLE before powering off the printer.

Paper feeder
and cassette The paper feeder is an optional assembly that holds the
cassette and feeds paper up into the feeder rollers. You
may see DEClasers with or without a paper feeder unit
in the field.
See Section 1.3 for more information about the cassette.

Front door release Opens the front door of the DEClaser 1100 series
printer.

Stack selector Directs paper from the fixing rollers exit to the faceup
or facedown stack.

Front paper tray
and extension plate The front paper tray holds up to 50 sheets of paper.
The image size is adjusted by selecting a paper size
from the page format menu. See Section 2.16 for more
on the format menu.

Adjustable and fixed
paper guides The left guide can be adjusted for standard size paper,
envelopes, or for nonstandard size sheets.

Faceup stack
exit roller The faceup tray that attaches here is not shown. Use
the faceup stack when printing on stiff media, for
example, envelopes or labels.

Fixing door Open this door to clear paper jams that occur at the
exit of the fixing unit. When open, the message
12 PRINTER OPEN is displayed.

Front door Open this door to clear media jams, remove and replace
the EP-L cartridge, or to access the density adjustment.

1.2 Printer Components
Figure 1–2 identifies the components on the back of the DEClaser 1100 series
printers. The DEClaser 1152 printer has a DEC423 serial and LocalTalk
connector; it does not have a video interface. Table 1–2 describes each
numbered component.

Rear cover Remove the access cover to install the optional 1- or
2-Mb RAM expansion memory.

Power cord
connector This receptacle accepts the ac line power cord.

Parallel (Centronics)
interface connector Accepts a 32-pin cable and is used for parallel
interfacing to a host computer system. The connector is
physically and electrically compatible to the Centronics
protocol.

Serial number This is the location of the external serial number
template. The location of the internal serial number
template can be found in Table 1–4. Both templates
show the same serial number.

Video interface (1100,
1150) and
DEC423 serial interface
(1152)
On the DEClaser 1100 or 1150 printer, the video
interface accepts a 37-pin cable that connects an
external video controller to the printer.
On the DEClaser 1152 printer, this interface is used as
a DEC423 serial connector.

Serial (RS232)
interface cable
connector
Accepts the standard, 25-pin interface connector that
is mechanically and electrically compatible with EIA-
232-D/CCITT V.24 specifications. The terms RS232 and
EIA-232-D are interchangeable.

SerialB/LocalTalk
interface connector Can be used as a serial RS-422 communication device
on the DEClaser 1152 only.
For more information about the cables or cable installation refer to Appendix A, DEClaser 1100
Printer Installation Guide, or DEClaser 1152 Printer Installation/Operator’s Guide.

holds the interface board and the parallel, video, and
serial input ports. On the DEClaser 1152 printer,
the interface board is similar in form and function.
However, the DEC423 serial port replaces the video
port and the LocalTalk connector has been added.
Customers must remove the interface board to install
optional memory.
