1.1 Fine Print Quality

The PrintPartner 20W uses electrophotography and a semiconductor laser unit that is compact, easy to control, and
consumes very little power.

The print resolution is 600 × 600 dpi (23.6 lines/mm). It is 1200 × 1200 dpi (47.2 lines/mm) at the half speed.
Natural curves and very fine lines are printed clearly.

With the smoothing function enabled, the print resolution is equivalent to 2400 × 600 dpi (horizontally 94.5 lines/
mm and vertically 23.6 lines/mm). Graphic and curve are printed quite smoothly. The smoothing function is valid
in 600 dpi mode.

See Appendix B about font samples.

1.2 Quiet Operation

The PrintPartner 20W generates about 50 dBA of sound level (ISO standard) while printing with the standard paper
tray (54 dBA while duplex printing with the optional fourth paper tray). The sound level is 40 dBA in standby state.
It is quiet enough for an office environment.

1.3 Easy Paper Handling

The PrintPartner 20W uses a 250-sheet universal-size paper tray (tray 1). An additional 250- or 500-sheet universal­size paper tray is offered with an optional paper feeder (trays 2 to 4).

Paper is loaded automatically from the paper tray and ejected to the top cover (250-sheet stacker) face-down in the
correct order.

A 100-sheet multi-function feeder (MFF) is provided for printing on the media shown below. It can be used for
printing by manual insertion of a sheet. A 20-sheet rear stacker (face-up) is also provided for printing these media.

• Envelopes

• Adhesive labels

• Transparencies

• Heavy or special paper

1-3

1.4 High Reliability and Easy Maintenance

The PrintPartner 20W design has been simplified. The print unit and the toner bottle can be removed and replaced
easily without getting hands dirty.

A variety of functions are integrated onto a single printed circuit board (main controller). A mechanism controller
board including driver circuits is provided separately from the main controller.

The self-diagnostics function checks printer hardware.

Almost all printer operations and regular maintenance procedures (handlimg paper and replacing consumables) are
performed from the front, right side, and rear of the printer. The side cover is removable.

The above items have improved reliability and made maintenance easier, both for general users and service
technicians.

1.5 Compact, Lightweight, and Small Footprint Design

The PrintPartner 20W has such a small footprint that it can be installed in a small space in an office. It can be set up
immediately thanks to its lightweight and compact design.

1.7 Environment Friendly

The PrintPartner 20W uses a toner recycle mechanism that does not generate toner waste. This means that the
printer uses toner effectively and the operator does not need to deal with wasted toner.

The power-saving design (intelligent heater on/off sensing) reduces power consumption.

Ozone emission is low.

Plastic parts are marked with the plastic content for ease of product recycling.

The user-selectable economy mode extends the lifetime of the toner bottle.

1-5

1.8 User-Friendly Operation

The control panel consists of eight push-button switches, four LED indicators, and an LCD (two lines by sixteen
characters).

The LED indicators provide printer’s basic status information and the LCD provides status and error messages by
language.

Print menu, such as a message language, paper size, and line spacing, can be set easily using the control panel or
remotely using the utility programs, MarkVision™ and PPMENU.

1.9 Duplex Printing Capability

An optional duplex unit is provided for double-sided printing. It can be installed into the slot where the standard
paper tray is originally installed. In this case, an optional feeder unit must be added and the standard paper tray
must installed into the slot of the optional feeder unit.

1.10 Wide Variety of Media

The PrintPartner 20W can handle the following wide variety of media.

• Copy paper including recycled paper

• Heavy or special paper

• Envelopes

• Adhesive labels

• Transparencies

It also can handle the following wide variety of sizes.

• A5, A4, A3

• JIS B5, JIS B4

Figure 2.1 Printer block diagram

(1) Printer

The printer consists of a main controller, a control panel, a printer mechanism, a mechanism controller, paper
feeding mechanisms including paper feeders, a power supply, and covers.

The printing mechanism consists of a laser unit, a print unit (photoconductive drum, developing magnet roller,
precharger), a toner bottle, a transfer charger, and a fuser unit.

2-2

Images are printed using an electrographic process:

The laser unit, modulated by video signals, sends light to the photoconductive drum and generates a latent
electrostatic image that is converted to a toner image in the print unit. The paper attracts the toner image from
the photoconductive drum, and the image is transferred to the paper.

Heat generated by the heat roller fuses the transferred toner image to the paper, and the paper is ejected to the
stacker.

The photoconductive drum is then cleaned for the next printing.

The above operations are continuous and enables uninterrupted quality printing.

(2) Controller

The controller controls the interfaces to the computer, mechanism controller, and control panel.

(3) Control panel and MarkVision/PPMENU

The control panel has LED indicators, LCD, and push-button switches. The LED indicators display basic
printer status, for example, whether the printer is online, whether the power supply is on, and whether an error
has occurred. The LCD shows status or error messages by characters. The push-button switches control printer
operation, for example, resetting the printer and printing a status report.

The printer setup can be changed using the control panel (in menu mode). It can also be changed remotely
using the printer utility programs, MarkVision™ and PPMENU.

See Chapter 4 for details on control panel operation and MarkVision/PPMENU.

(4) Interfaces

Two bi-directional Centronics parallel interfaces and an RS-232C serial interface are standard. Other interfaces
are available as an accessory. See Chapter 5 for details.

(5) Memory Expansion cards

The RAM card is used to expand the resident RAM memory (8 MB) to download soft fonts or to process more
data.

The RAM card is a SIMM type board and its memory capacity is 4M, 8M, 16M, or 32M bytes. RAM cards are
installed to the top and middle SIMM connectors on the controller board. So, up to 64 MB can be added.

(6) Emulation card (not available currently)

The emulation card is used to add a printer emulation.

The emulation card is a SIMM type board and is installed to the bottom SIMM connector on the controller
board.

*1 When no print data is not received for 15 minutes (default) after the last printing or warming-up, the printer

turns off the fuser’s heater and enters sleep mode. The control panel can inhibit the printer from entering
sleep mode.

*2 Print speed when paper size is specified.

*3 Print speed is 19.2 s when the 3rd paper tray is of 500 sheets.

*4 The warm-up time begins when the power switch is turned on until the printer becomes ready for printing

(“READY” displayed). Before, measuring, the printer must be left for a period long enough at 23˚C. The
warm-up time may increase if the toner is low, the toner bottle has just been replaced, the print density is
changed, or installation of options such as memory is changed.

*5 The first printing time begins when a print start signal is sent to the printer in the ready state until the first

printed sheet (A4, landscape) is completely ejected to the face-down stacker. The first printing time may be
about one minute after the paper size has just been changed. It may take more time if the printer starts from
sleep mode (see *1) or after changing the print density.

*6 Paper feed direction is portrait only for A5, A3, JIS B4, Legal, and Ledger sizes. Paper feed direction is

landscape only for A4, JIS B5, Letter, and Executivesizes.

*7 When printing using the MFF, specifying the size of paper used is recommended. If the size is not specified,

the in-page cumulative print position accuracy in the paper feed direction slightly gets lower as compared
with printing using a paper tray.

*8 Envelopes and OHP transparencies are for single-sided printing only. Do not print on both sides.

*9 For printing sheets of paper whose weights are 90 to 128 g/m2 or printing envelopes or OHP transparencies,

the face-up stacker must be used.

*10 The paper feed capacity may vary depending on paper types and environmental conditions.

3.2.4 Paper storage

To avoid problems with print quality and jams, store paper as follows:

Paper

feed

• Do not expose paper to moisture or direct sunlight. Overly damp paper may cause electrostatic charge to be lost.
Excessively dry paper may cause undesired electrostatic charge. Both cause poor print quality.

• Store remaining paper in tits original package, if possible. Otherwise, repackage them.

• Storing paper vertically may cause paper to curl, and cause jams.

4.2 Printer Utility Programs

The PrintPartner 20W is equipped with the three printer utility programs: Printer Management Utility Program,
MarkVision™; Printer Remote Setup Utility Program, PPMENU; and Remote Printer Utility Program. This section
describes MarkVision™ and PPMENU, standard for the PrintPartner 20W.

These utility programs can be used in the environments shown below:

4.2.1 MarkVision™

MarkVision™ by Lexmark is an integrated software for managing printers, stored in the “PrintPartner Software CD­ROM” which comes with the printer. It has the following main functions:

• Monitoring the printer

• Displaying the printer status and features (including options) and statistics

• Providing the printer control panel on the computer’s screen (remote control panel)

These functions are most effective and valuable for remote printers in network environments.
MarkVision™ is automatically activated when an abnormal condition occurs in the printer. It operates in Windows
95 environments only.

The remote control panel is quite a nice function that enables the user to easily and remotely operate the printer even
if the printer is set up remotely. MarkVision™ displays the printer control panel on the computer’s screen and gives
the user the exactly same functions as available with the control panel of the printer. The user can perform a func­tion by clicking a button on the computer’s screen without pushing a button of the printer’s control panel.

4-4

To use MarkVision™, the computer and its operating environments must be as follows:

• IBM PC/AT or compatible or PS/2

• Microsoft Windows 95/98 or NT 4.0 (not Windows 3.X)

• VGA (640 x 400) or higher display

• Hard disk drive installed (9 MB essential for MarkVision™)

• CD-ROM drive

Menu Bar Functions

The top menu bar offers three functions. The screen displays information and a graphic of the printer corresponding
to the function selected. The bottom line displays printer status. Help is available from each screen.

The three functions of the top menu bar are as follows:

Status: Shows a printer status message which is identical to the message appearing on the printer control panel. The
status is also indicated graphically. The user can determine what the printer is doing and what the printer needs to
complete the task. It also includes information about the printer’s features including options which are installed on
the printer.

With an optional setting, the MarkVision™ icon flashes to let the user know there is a problem with the printer even
if the icon is minimized on the monitor.

Control Panel: Allows the user to remotely operate the printer. It displays an exact replica of the physical control
panel on the printer, on the monitor. The user can click the appropriate button on the screen by the mouse as if he is
pressing the real button on the printer control panel by a finger. Both panels have exactly the same functions.

Statistics: Summarizes details about jobs such as the total number of jobs printed, total pages, and average print
time.

4-5

4.2.2 PPMENU

PPMENU, stored in the “PrintPartner Software CD-ROM” which comes with the printer, allows the user to change
printer’s features directly from the computer display and keyboard. Operations are easy enough that the user’s
manual need not be referenced once the user is familiar with the printer.

PPMENU is useful to configure the printer to suit the requirements of user’s computer, software, and documents to
be printed.

The parameters changed using PPMENU affect page layout, font, and printer control. If software programs have
printer drivers, the printer drivers control these parameters for the user. The user may never need to change the
settings manually using PPMENU.

To use PPMENU, the computer and its operating environments must be as follows:

• IBM PC/AT or compatible or PS/2

• PC DOS 5.02, MS-DOS 3.3, or higher or
Windows 3.X or Windows 95 in DOS full screen mode

• VGA (640 x 480 dots) or higher display

• Hard disk drive installed (1 MB essential for PPMENU)

• CD-ROM drive

Main Menu and Menu Bar Functions

The PPMENU’s main menu offers functions to select print options for user documents. It also offers an operation
guide of some keys and a help message line. If the printer is not ready or has an error, a status message is displayed.

The top menu bar offers the three pull-down menus: library, special, and options. The user can select parameter
options or perform a function by using the main menu and top menu bar accessed through the mouse or keyboard.

One of the six languages is selectable for messages when installing PPMENU.

The following shows the structure of the menus in PPMENU. An asterisk (*) indicates a default option.

4.3 Printer Drivers

Printer driver is a software acting under MS-Windows 3.X, 95/98, NT 3.51, or NT 4.0 and provides the printer with
the information which can be read by the printer. Internal values of printer environments can be specified by the
printer driver, and the user can specify paper size, resolution and/or other selectable values.

To use the printer driver, the computer and its operating environments must be as follows:

• IBM PC/AT or compatible

• Microsoft Windows 3.X, 95/98, NT 3.51, or NT 4.0

• VGA (640 x 400) or higher display

• Hard disk drive installed (2 MB essential for a printer driver)

• 3.5” double-sided high density (2HD) floppy disk drive or CD-ROM drive

CHAPTER 5 INTERFACE INFORMATION

5.1 Overview

The PrintPartner 20W printer communicates with the host through two parallel interfaces and a serial interface or an
optional interface. The printer automatically selects the interface proper to the occasion. This chapter describes the
parallel and serial interfaces. For locations of the parallel and serial interface connectors and the optional interface’s
slot, see Figure 1.3.

5.2 Parallel Interface (IEEE 1284-B Connector)

The parallel interface is a bidirectional Centronics interface (nibble mode of the IEEE 1284 standard is supported).

Description

• Data 1 to Data 8 signals correspond to parallel
data bits 1 to 8.

• Data 8 is the most significant bit.

• All signals must go high at least 0.5 µs before
the falling edge of the Data Strobe signal, and
must stay high for at least 0.5 µs after the rising
edge.

• Pulse signal indicating data reception completed
(or data reception enabled) status

• Issued when the printer switches from offline to
online

Reverse data transfer phase:
This signal goes high when data being sent to the
host is established.
Reverse idle phase:
This signal is set low then goes high to interrupt the
host, indicating that data is available.

Data cannot be received when this signal is high,
e.g., if the buffer is full or an error occurs.

Reverse data transfer phase:
Data bit 3, data bit 7, then forward path (host to
printer) busy status

This signal goes high if paper runs out.
Reverse data transfer phase:

Data bit 2, then data bit 6
Reverse idle phase:
This signal is set high until the host requests data
and, after that, follows the Data Available signal.

This signal goes high when the printer is selected
(online), and goes low when the printer is deselected
(offline).

Reverse data transfer phase:
Data bit 1, then data bit 5

Reserved (*1)
Reverse data transfer phase:

This signal is set low when the host can receive data,
and goes high when the host has received data.
Following a reverse data transfer, the interface enters
the reverse idle phase when the Host Busy signal goes
low and the printer has no data.
Reverse idle phase:
This signal goes high when the Printer Clock signal
goes low so that the interface re-enters the reverse
data transfer phase. If it goes high with the 1284
Active signal low, the 1284 idle phase is aborted and
the interface returns to the compatibility mode.

5.2.3 Data transmission timing

The PrintPartner 20W uses a bi-directional parallel interface complying with IEEE 1284. This interface is also
compatible with the conventional Centronics interface. Data transfer from host to printer is performed according to
Centronics standard, called compatible mode. Data transfer from printer to host is performed according to the IEEE
1284 standard, called nibble mode.

In compatible mode, the printer receives data from the computer in handshaking mode based on the Busy and
Acknowledge signals from the printer and the Data Strobe signal from the computer. For the Data Strobe and
Acknowledge signals, the timing of the Busy signal must be as shown in the compatible mode of Figure 5.4a.

To send data from the printer to the host, the interface enters the nibble mode where data is sent in units of four bits
(nibble) using four output signal lines as data paths. The data transfer sequence in nibble mode involves negotiation
phase, reverse idle phase, reverse data transfer phase, and termination phase. Figure 5.4b shows the reverse data
transfer phase where data is sent.

5.4.5 Data protocols

Different types of protocols are used for the RS-232C serial interface, depending on the computer manufacturer.
These protocols prevent the print data receive buffer from overflowing because interface data transmission is faster
than buffer data printing. The printer uses specific character codes or an interface signal for each protocol to inform
the computer of the buffer status, as follows:

(1) X-ON/X-OFF or DC1/DC3 protocol

With either protocol, the XOFF (DC3) code (hexadecimal 13) is transmitted from the printer when less than 255
bytes of buffer space remains. The XON (DC1) code (hexadecimal 11) is transmitted when less than 255 bytes
of data remains in the buffer.

Normal data processing cannot be guaranteed if data is transmitted to the printer when insufficient buffer space
is available after the XOFF code has been transmitted.

When the printer is first turned on, the DTR signal is set to the space state (ready) and an XON (DC1) code is
transmitted from the printer. When the printer is placed offline, the XOFF code is transmitted even if the buffer
is not full. The XON code is transmitted when the printer is placed online again.

5-16

(2) DTR protocol

The DTR signal is set off (low). That is, the Busy signal is issued when 255 bytes of data remain in the buffer.
When the printer is placed offline, the DTR signal is set off (low).

Transmission must stop within 255 bytes after the DTR signal is set off (low).

The validity of data cannot be guaranteed if data exceeding the buffer capacity is transmitted regardless of the
DTR signal.

Buffer-full recovery timing:

Data transmission is suspended while the DTR signal is set off (low), but printing continues. When the buffer
empty area exceeds 255 bytes, the DTR signal is set on (high) indicating that the printer is ready to accept data.

5-17

CHAPTER 6 MAINTENANCE

6.1 Overview

The PrintPartner 20W printer, with its simple mechanism and latest electronics techniques, is highly reliable and
easy to maintain. Changing spare parts require no adjustments so that replacement is easy.

6.2 Preventive Maintenance

No scheduled maintenance is required. However, it is recommended that the printer be kept clean to increase the
service life and MTBF.

6.3 Maintenance Philosophy

The printer is designed to make maintenance as infrequent as possible. No periodic lubrication is required.

Quality assurance

• Every unit is checked before assembly.

• All products go through full inspection.

• All spare parts are easy to change. (MTTR: 0.5 h)

6.4 Diagnostics

6.4.1 ROM/RAM check

When power is turned on, a ROM sum and RAM write/read check are performed automatically.

6.4.2 Error display

Printer operation is checked by firmware and, if an error is detected, the error status is displayed on the LCD on the
control panel.

6-1

6.5 Maintenance Tool

6.5.1 Self test printing

The SELF TEST button prints a setup report page which summarizes printer option settings. It can be used to easily
check the electrical and mechanical states of the printer without the help of a computer. It also distinguishes
between printer and computer errors, and confirms correct operation after an error recovery. The PRINT FONT
button can be used instead. It prints font report pages which list all available fonts.
