Installation

The duplexer fits onto the bottom of the printer or of the optional paper feeder (if the optional paper feeder is installed together with the duplexer).

CAUTION Before installing (or removing) the duplexer, be sure to turn

off the printer’s power.

Figure 2 on page iv shows allowable printer configurations including the duplexer. Depending on other optional units installed together with the duplexer, different paper path adaptors are required. Note that any configuration containing the duplexer also requires the optional paper handler/stacker. For details on how to install the optional paper handler, see the instructions provided with the optional paper handler/stacker.

Installing the duplexer with no other option units

If the duplexer is the only option unit you will be using with the printer, it mounts directly under neath the printer as shown in Figure 2(a). The printer sits directly on top of the duplexer.

1. Install the optional PA-20 paper path adaptor on the duplexer as shown

in Figure 3.

• Pull the duplexer drawer slightly open.

• Align the tabs with the slots.

• After fitting the tabs to the slots, slide the paper path adaptor to the

left to lock.

• Close the duplexer drawer.

2. Next, align the positioning pins on top of the duplexer and the lock pin

on the paper path adaptor with the holes in the base of the printer, then slowly and carefully lower the printer onto the duplexe r. Hold the printer level while lowering it onto the duplexer, and make sure that the connector on the duplexer fits squarely into the corresponding connector in the base of the printer. (Fig. 4)

3. Install the optional paper handler/stacker. For details, see the instructions

provided with the paper handler/stacker.

Installing the duplexer together with other option units

The duplexer mounts underneath the paper feeder as shown in Figure 2(b). In this configuration, the printer sits on top of the paper feeder.

1. If you will be using the duplexer together with a paper feeder, you must

install the PA-1 paper path adaptor on the rear of duplexer. Install the PA-1 as shown in Figure 5.

• Align the tabs with the slots.

• After fitting the tabs to the slots, slide the paper path adaptor in the

direction indicated by the arrow to lock it. See Figure 6 for how to remove the PA-20.

2. Next, install the paper feeder on top of the duplexer as shown in Figure

7. Align the positioning pins on top of the duple xer and the lock pin on the paper path adaptor with the holes in the base of paper feeder, then carefully lower the paper feeder onto the duplexer. Hold the paper feeder level while lowering it onto the duplexer, and make sure that the connector on the duplexer fits squarely into the corresponding connector in the base of the paper feeder.

Note You can stack two paper feeders on top of one another. For

details, see the paper feeder instruction manual.

3. Install the optional PA-20 paper path adaptor on the paper feeder as

shown in Figure 3.

• Align the tabs with the slots.

• After fitting the tabs to the slots, slide the paper path adaptor to the

left to lock.

English

4. Lower the printer onto the paper feeder. Observe the same precautions as

when lowering the paper feeder onto the duplexer. (Fig.4)

5. Install the optional paper handler/stacker. For details, see the instructions

provided with the paper handler/stacker.

Printer memory for duplex printing

With duplex printing, the printer basically needs twice as much memory as is required for simplex printing. Further, depending on the printer and the selected printing environment, it may be necessary to expand printer memory in order to perform duplex printing. For memory requirements, see the printer's User's Manual.

Duplexer modes

The duplexer allows you to print on both sides of the paper. Fir st the printer prints on one side of the paper in the usual manner. Then it sends the paper to the duplexer, which turns it over to allow printing on the other side. Figure 8 shows the path through which paper travels when printing in the duplex mode.

Binding setups

The term binding refers to the manner in which printed pages of paper are joined together when pages are joined together (by gluing, stitching, etc.) in book form. The two possible types of binding are long-edge binding, in which pages are joined together along their long edge; and short-edge binding, in which they are joined together along their short edge. In selecting a binding type, you must also consider the orientation of the printed page. You can use long-edge or short-edge binding with either landscape or portrait printing.

Depending on the binding type and print orientation, the duplexer provides four types of binding setups. These are: (1) portrait, long-edge, (2) portrait, short edge, (3) landscape, long-edge, and (4) landscape, short-edge. Figure 9 shows these binding setups.

With portrait, long-edge binding and landscape, short-edge binding [setups (1) and (4) in Figure 9], text on both sides of the paper is oriented in the same direction.

English

With portrait, short-edge binding and landscape, long-edge binding [setups (2) and (3) in Figure 9], text on the rear side of the paper is printed upside down with respect to that on the front side.

Mode Selection

You can enable the duplexer by selecting the Duplex mode option using the MODE key on the printer’s control panel, or b y means of PRESCRIBE or PCL mode selection commands.

Mode selection by MODE key

To select duplex printing and binding setup from the printer's control panel, proceed as follows. (For printer control panel key operation, also see the printer's User's Manual.)

1. Make sure that the printer is ready and on-line.

2. Press the MODE key on the printer’s control panel.

3. Follow the key operation procedure for each printer until the message

display indicates Duplex mode. The current duplex mode is indicated by one of the following messages:

None Short edge bind Long edge bind

The default duplex mode is None.

4. To change the duplex mode, press the ENTER key. The message display

shows a blinking question mark (?).

5. Press the + or - key until the display shows the desired binding type. If

you want to abandon the duplex mode selection procedure, press the

CANCEL key now. The duplex mode remains unchanged.

6. Press the ENTER key to set the new duplex mode.

7. Press the EXIT key and the message display returns to Ready.

Complete the binding setup by selecting the appropriate print orientation, portrait or landscape. See the printer’s instruction manual for the procedure.

Note While using the duplexer, you can also select face-up or face-

down delivery of printed pages. Select a delivery type that suits your needs. For information on this procedure, see the printer's User's Manual.

Manual feeding

Duplex printing is not available if paper is fed manually from the printer’s manual feed tray or using the optional envelope feeder. If the paper is fed manually while the duplexer is activated, the printer automatically deactivates the duplex mode and delivers all output pages to the face-up tray.

Mode selection by command

As an alternative to the control panel selection procedure described on page 9, you can select duplex printing and the binding mode setup using certain PRESCRIBE and PCL commands. These commands also provide certain functions that a re not available from the control panel.

The PRESCRIBE duplex control commands and their functions are:

❐ DUPX (select/deselect DUPleX mode) ❐ DXPG (select DupleX PaGe side)

The PCL commands provide the same functions as the PRESCRIBE commands listed above. However, unlike the PRESCRIBE commands (which can be used in any printer emulation mode), the PCL commands are only effective while using the printer in the HP LaserJet emulation (PCL) mode.

The PCL duplex control commands and their functions are as follows.

English

❐ <Esc>&l#S (select/deselect duplex mode) ❐ <Esc>&a#G (select duplex pa ge side)

PRESCRIBE commands are described in detail below.

PRESCRIBE commands

DUPX (select/deselect DUPleX mode)

Format DUPX mode;

Parameters mode: a number from 0 to 2

The DUPX command instructs the printer to select or deselect duplex printing and selects the duplex mode. The parameters are as follows.

0=Select simplex mode 1=Select duplex mode, long-edge binding 2=Select duplex mode, short-edge binding

The default duplex mode can be selected by the FRPO N4 command. The parameter values are the same as the DUPX command above. For example, to power up the printer with the long-edge duplex binding mode, enter the command:

ECHO !R! FRPO N4, 1; EXIT; > LPT1

For LPT1, substitute the port to which the computer is connected.

DXPG (select DupleX PaGe side)

Format DXPG side;

Parameters side: a number from 0 to 2

The DXPG command ends printing on the current page in the same manner as a form feed. However, unlike the form feed, it also selects the paper side, front or back, on which printing of the ensuing page is printed. The parameters are as follows.

0=Select next side (same as with a form feed) 1=Select front side (printing of the ensuing page begins on the front side of the next sheet, regardless of whether the curr e n t page was printed on the front or back side of the current sheet) 2=Select back side (printing of the ensuing page begins on the back side of the current sheet if the current page was printed on the front side, or on the back side of the next sheet if the current page was printed on the back side)

Example

The following example selects the duplex mode with short-edge binding, selects to portrait page orientation, and prints text on both sides of the page. The result is as shown in Figure 10.

!R! CMNT Initiates a PRESCRIBE command sequence; RES; CMNT Causes a page break and resets parameters; DUPX 2; CMNT Selects duplex mode, short-edge binding; SPO P; CMNT Selects portrait orientation; STAK 1; CMNT Select face-down delivery; EXIT; This text prints rightside-up on the front side of the page. !R! DXPG 0; CMNT Ends current page (front side of the paper); EXIT; This text prints upside-down on the reverse side of the page. !R! RES; EXIT;

English

Troubleshooting

This section explains how to handle paper jams in the duplexer and respond to error messages.

Paper jam

In the event of a paper jam, the Paper jam message appears on the printer’s message display.

Note When clearing jams, check other option units (the paper

handler/stacker, paper feeder, sorter, and bulk paper stacker) for jammed paper before pulling out the DU-21’s duplexer drawer. To check for other option units for jams, open their rear covers.

If paper jams inside the duplexer, the READY indicator flashes on the duplexer’s indicator panel. To clear the jam, first check other option units for paper by opening their rear covers. Remove any paper you find. Then pull the duplexer drawer part-way open. If paper is visible under the clear plastic cover, open the cover and remove the paper as shown in Figure 11(a).

If the paper is stuck inside the duplexer, turn the knob on the left side of the duplexer drawer counterclockwise [see Figure 11(b)] to move the paper out of the duplexer.

If the paper jams at the rear of the duplex unit, open the rear cover and remove it.

Whenever you clear a jam, be sure to check inside other option units, as well as inside the duplexer drawer and the duplexer’s rear cover.

After clearing the jam, reclose the drawer, open and close the printer’s top cove r or the paper feed unit. Then the printer automatically warm up, goes on-line, and continue printing. Depending on the part at which the jam occurred, the printer may or may not print the jammed page.

Error message

If the printer’s message display shows Duplex unit front cover Open or Duplex unit rear cover Open, check the front/rear covers and ensure that they are securely closed.

Adjusting the print position

When using duplex printing, the image on the reverse side of the paper may be slightly out of alignment with that on the front side. If this occurs, the image position can be adjusted either to the left or right by about 2 mm. When using the duplex unit, the reverse side of the paper (the second page) is printed first, followed by the front side (the first page). Adjustment of the print position affects only the image printed on the front side of the paper; i.e., print positioning on odd-numbered pages.

Adjustment procedure

1. Prepare a double-sided print sample using the duplex printing mode.
