FEATURES / TIPS

Forms Tear-Off

The Forms Tear-Off feature allows a printed continuous forms page to be torn off without wasting paper or adjusting the printer.

507 cps

95 cps

570 cps

When printing stops, Forms Tear-Off automatically moves the paper to align the perforation with the tear bar (located under the access cover), after a time interval which you select through the menu.

Paper remains in the tear-off position until the printer receives more data. Then, the paper moves back down for printing.

This feature has to be enabled.

Paper Park

Your printer’s paper park feature allows you to print a single sheet (cut-sheet) page without removing continuous feed paper from the printer.

For more information, see “Paper Park” in “Using your Printer”.

INTERFACES - GENERAL

Your printer is equipped with a selection of data interfaces:

Under no circumstances attempt to use both parallel and USB ports simultaneously.

1. Parallel

bi-directional (IEEE 1284 compliant) parallel cable.

2. USB

(not Windows 95 upgraded Windows NT 4.0 does not support USB. Administrator

– For direct connection to a PC. This port requires a

– For connection to a PC running Windows 98 or above

to Windows 98) or Macintosh.

PRINTER DRIVERS > 10

privileges are necessary for Windows 2000 and Windows XP installations.

This port requires a cable conforming to USB version 1.1 or above. A genuine cable displays the Trident symbol on both connectors.

Using an inferior cable can cause printing problems and special cables are needed for longer runs than five metres

The operation of a printer is not assured if a USB compatible device is connected concurrently with other USB compatible machines.

When connecting multiple printers of the same type, they appear as *****, ***** (2), ***** (3), etc. These numbers depend on the order of connecting or turning on each printer.

CONNECTING THE USB CABLE

Due to the number of possible variants of operating systems it is not possible to describe every combination.

Terminology may vary between Windows operating systems and some knowledge is assumed. If you are unsure how to proceed, you should consult your computer documentation or system manager for details. This example uses Windows 2000 Professional.

Ensure the printer and computer are easily accessible and turn

both units off. This is not strictly necessary but may prevent any problems being caused by the accidental dislodging of power or other cables.

Plug the Series A male connector (a) into

the the computer’s USB port or into a suitable USB hub.

Plug the Series B Male connector (b) into

the printer’s USB port.

Switch on both the computer and printer.

PRINTER DRIVERS > 11

The printer will be identified

immediately by the New Hardware Wizard and install itself in the Printer folder. An additional item, USB Printing Support will also appear in the Device Manager each time the printer is switched ON and connected.

Check that the default paper size has

been correctly set by looking at the settings in the Settings > Printers folder. Under the printer's Properties > General tab, the current paper selection is shown. The printer picks up its initial setting from the Locale settings on the host computer. The paper size can be altered by using the drop down arrow and selecting an alternative size.

If the printer had formerly been used as a parallel or serial

device and there is no output from the printer once a USB cable has been connected, check to see that the correct port has been selected. This information can also be found in the Properties folder but under the Ports tab. Amend as necessary.

If there are printing problems, check to see whether there is a

USB connection active in the Control Panel. If there is no USB connection shown, you must install the hub.

Alternatively, there may be a problem if the printer is

connected via a USB hub. Disconnect the printer cable from the hub and connect it directly to the computer.

TOP OF FORM (TOF)

Top of Form (TOF) sets the print start position. The factory default is 1" from the top.

The TOF can be changed in increments of 1/144", for either a single print job, or all print jobs. The overall amount of adjustment is limited to avoid paper jams.

The first line prints at the red line of the plastic paper shield (1) on the printhead.

CAUTION!

If you turn the platen knob when the printer is not at Top of Form, the TOF will misalign. Always feed the paper to TOF before turning the platen knob.

NOTE

> Your software may print the first line of print above or below where

TOF is set. You may need to adjust the TOF to meet your software’s requirements.

> The Top of Form and Forms Tear-Off settings of your printer interact.

How you set the Top of Form depends on whether ON (set to 500 ms, 1 sec, or 2 sec) or OFF (the factory default setting).

FORMS TEAR-OFF FEATURE

This feature is normally turned off. To use Forms Tear-Off, you must enter the menu and change the setting to the desired time interval (see “Changing the Forms Tear- Off Settings”).

The Forms Tear-Off feature allows a printed continuous forms page to be torn off without wasting paper or adjusting the printer. It can be used for rear feed continuous forms, bottom feed continuous forms (with the optional push tractor installed), or for top feed roll paper (with optional roll paper stand installed).

When the printer is turned on, the paper feeds to the tear-off position.

USING YOUR PRINTER > 18

When data is received, the paper automatically moves down to the print position (TOF) and printing begins.

NOTE

You can also move the paper down to the print position manually by pressing

When printing stops, Forms Tear-Off automatically moves the paper to align the perforation with the tear bar (located under the access cover), after the time interval which you selected through the menu.

Paper remains in the tear-off position until the printer receives more data. Then, the paper moves back down for printing.

NOTE

> The status of the Forms Tear-Off menu setting affects how you set

the Top of Form: see “Top of Form (TOF) and Forms Tear-Off” earlier

engaged.

POTENTIAL ISSUES WITH SOFTWARE PACKAGES

If Forms Tear-Off is set to ON and the software package you are using “pauses” for a long enough interval while sending data to the printer, Forms Tear-Off may be activated. No data is lost, but this causes uneven print registration due to the paper movement.

If this occurs, use the menu to turn off this feature, then use the TEAR key to move the paper up to the tear position manually (see “Changing the Forms Tear-off Settings”).

EXPLANATION OF MENU ITEMS

These explanations are in alphabetical sequence to make it easier to look them up. Some items only appear when optional accessories are installed; others appear in several groups in the menu.

7 or 8 Bit Graphics, Default = 7

Change this setting to 8 if your system uses 8-bit graphics.

7 or 8 Bit Data Word, Default = 8

Change this setting to 7 if your system uses 7-bit data word lengths.

Auto CR, Default =No

IBM emulation only. If you want the printer to automatically add a carriage return when a Line Feed is received at the end of a line, change the setting to Yes.

Auto LF, Default = No

If your printout is consistently double spaced, select No; if it overprints, select Yes.

Auto Feed XT, Default = Invalid

Epson emulation only. In the Epson emulation, the XT signal on pin 14 of the parallel interface can control automatic line feed. Some interface cables are wired in such a way that automatic line feed is always in effect: this item eliminates this potential problem. If your system uses pin 14 of the parallel interface to control automatic line feed, change the setting to Valid.

Auto Select, Default = No

Determines whether or not your printer will automatically be selected after you load in paper. With the factory default engaged, the printer will be deselected so that you can set the Top of Form. If you always use the same Top of Form position, change the setting to Yes.

MENU MODE > 34

Baud Rate, Default = 9600 bps

Appears only if optional Serial Interface is installed. Set this to match your system’s transmission speed.

Bi-direction, Default = Enable

Change this setting if you wish to disable bi-directional transmission (PnP) in Nibble mode.

Bottom Margin, Default = Valid

Change to Invalid if you want the printer to ignore the bottom margin setting.

CAUTION!

Setting the Bottom Margin to Invalid can cause loss of data and damage the printhead by allowing printing without paper.

Busy Line, Default = SSD-

Appears only when the optional Serial Interface is installed. If Ready/ Busy protocol (factory default) is selected, you can choose which line your system monitors for a busy signal:

l SSD -9V, select SSD-

l SSD +9V, select SSD+

l DTR -9V, select DTR

l RTS -9V, select RTS

Busy Time, Default = 200 ms

Appears only when the optional Serial Interface is installed. Sets the length of the busy signal when the Ready/Busy protocol (factory default) is engaged.

Centering Position, Default = DEFAULT

Used to limit printhead travel when printing narrow columns.

l Select Mode 1 for the narrow carriage printer.

l Select Mode 1 or Mode 2 for the wide carriage printer.

MENU MODE > 35

Character Set, Default = IBM Set II

Epson and IBM emulations only. Use this to switch character sets to IBM Set II.

Character Set, Default = Standard

MICROLINE emulation only. Use this to switch the character set to Line Graphics.

Code Page, Default = USA

USA, Canada French, Multilingual, Portugal, Norway, Turkey, Greek_437, Greek_869, Greek_928, Greek_437 CYPRUS, Polska Mazovia, Serbo Croatic I, Serbo Croatic II, ECMA-94, Hungarian CWI, Windows Greek, Windows East Europe, Windows Cyrillic, East Europe Latin II - 852, Cyrillic I - 855, Cyrillic II - 866, Kamenicky (MJK), ISO Latin 2, Turkey_857, Windows Turkey, Ukrainian, Bulgarian, ISO Latin 6 (8859/10), Windows Baltic, Baltic_774, KBL-Lithuanian, Cyrillic Latvian, Roman-8, Icelandic-861, Multilingual 858, ISO 8859-15 Greek_737.

CSF Bin Select, Default = Bin 1

Appears only when the optional Dual-Bin Cut Sheet Feeder is installed. Use this to switch to Bin 2 as the default.

CSF Type, Default = Wide

To avoid paper jams, change this setting to Narrow if you are using the optional Cut Sheet Feeder on the wide model ML5521 printer.

Diagnostic Test, Default = No

Appears only when the optional Serial Interface is installed. Select YES to perform a diagnostic test of the serial interface.

DRAFT Mode, Default = HSD

Applies only when the Print Mode is set to DRAFT. Selects the draft mode to be used: HSD (High Speed Draft) or SSD (Super Speed Draft).

MENU MODE > 36

DSR Signal, Default = Valid

Appears only when the optional Serial Interface is installed. Used with the Ready/Busy protocol (factory default) to select the way your system handles the DSR signal.

DTR Signal, Default = Ready On Power Up

Appears only when the optional Serial Interface is installed. Change to Ready On Select if the DTR signal is required when the printer is selected (leave as Ready On Power Up if the DTR signal is required when the printer is turned ON).

Emulation Mode, Default = IBM PPR

Selects the printer command set (emulation) you want to engage.

ESC SI Pitch, Default = 17 cpi

Sets the character pitch used when the ESC SI command is received.

Form Tear-Off, Default = Off

Choose 500 ms, 1 sec, or 2 sec to turn the Form Tear-Off feature ON and to set the time interval for the printer to wait before advancing the paper.

Graphics, Default = Bi-directional

Change to uni-directional graphics for better registration, but slower printing. With this set for bi-directional, you can optimise the registration using the Print Registration setting in the Menu.

I-Prime, Default = Buffer Print

Determines what the printer will do when it receives the I-Prime signal from the software.

Buffer Print

Buffer Clear

Invalid

: prints out the buffer contents before resetting.

: dumps the buffer contents immediately.

: causes the printer to ignore the I-Prime command. Select this setting if you wish to enter settings through the printer’s control panel which will not be automatically

MENU MODE > 37

overridden by the software’s settings when the I-Prime signal is sent.

Language Set, Default = ASCII

Replaces certain standard symbols with special characters used in foreign languages.

Line Spacing, Default = 6 lpi

Change to 8 lines per inch (lpi) to get more lines on a page.

Operator Panel Function, Default = Full Operation

Change to Limited Operation to deactivate the

CHARACTER PITCH

buttons, so that these features can only be

and

controlled through your software. This prevents these from being changed from the control panel when several people are using the printer.

NOTE

This feature also prevents access to the Menu. To access the Menu in these circumstances, turn the printer off, then hold down the while turning ON the printer.

Page Length, Default = 11-2/3" or 1/2"

Selects the length of the paper you are using. This enables the printer to keep track of the initial printing position (TOF) on each page.

Page Length Control, Default = by Actual Page Length

If you wish to use the Paper End sensor to detect the actual paper end, use

Actual Page Length

setting. If you use “by Menu Setting”, the printer will disregard the Paper End (PE) and use the page length as set by the menu.

Page Width, Default = 13.6"

Wide carriage model only.

SEL

key

MENU MODE > 38

Paper Out Override, Default = No

Senses when less than 1" (25 mm) of paper remains and stops printing. Change to Yes to override the sensor and print closer to the bottom of the page.

CAUTION!

Engaging Paper Out Override can cause loss of data and damage the printhead by allowing printing without paper.

Parity, Default = None

Appears only when the optional Serial Interface is installed. Selects the type of parity your system uses: None, Odd or Even.

Pin 18, Default = +5V

Sets the signal on pin 18 to +5 volts or open.

Pitch, Default = 10 cpi

Choose the character width in characters per inch (cpi).

Power Save Time, Default = 5 min.

Sets the interval the printer waits for more data before it goes into the power save mode. Power Saving must be set to Enable (the factory default) for this to be effective.

Power Saving, Default = Enable

Change to Disable if you wish to prevent the printer from entering the Power Save mode after the selected interval.

Print Mode, Default = Utility

Choose the quality and typeface of printing. Switch to NLQ Courier or NLQ Gothic for Near Letter Quality printing. If you are printing draft-type documents, select DRAFT, then select either HSD or SSD under DRAFT Mode. Both of these Items are in the Font Group.

MENU MODE > 39

Print Registration, Default = 0

Change the setting as required to obtain the best registration for bidirectional printing.

Print Suppress Effective, Default = Yes

If your system uses the DC1 and DC3 codes for something other than the print suppress mode, change the setting to No.

Proportional Spacing, Default = No

Change the setting to Yes to engage proportional spacing of characters.

Protocol, Default = Ready/Busy

Appears only if the optional Serial Interface is installed. Change to X-ON / X-OFF if that is the type of protocol your system uses.

Receive Buffer Size, Default = 64K

Selects the amount of memory devoted to holding received data. Choosing 1 Line will tie up your computer while printing, but if you abort the print job, the printer will stop much sooner.

Reset Inhibit, Default = No

Select Yes if you wish the printer to ignore the reset command sent by software. This prevents your software from changing the settings you make through the front panel controls or through printer commands.

NOTE

This will also prevent your software from clearing out existing settings when you finish printing one document and switch to another.

Serial Data 7/8 Bits, Default = 8 Bits

Appears only if the optional Serial Interface is installed. Change to 7 Bits if your system uses a 7-bit data format.

MENU MODE > 40

SI Select Pitch 10 cpi, Default = 17.1 cpi

IBM emulation only. Sets the pitch to be engaged when the printer control panel is set for 10 cpi and the SI command is received.

SI Select Pitch 12 cpi, Default = 20 cpi

IBM emulation only. Sets the pitch to be engaged when the printer control panel is set for 12 cpi and the SI command is received.

Size, Default = Single

Change to Double for double width and height printing.

Skip Over Perforation, Default = No

Change to Yes if you want the printer to go to the next page when it comes within 1" (25 mm) of the bottom of the page. Keep it set to No if your software has its own page formatting controls.

Style, Default = Normal

Change to Italics if you want the printed characters to be slanted.

Time Out Print, Default = Valid

If your software spends a long time processing between portions of data it feeds to the printer, change the setting to Invalid to keep your printer from dumping the received data while it is waiting for more.

MENU MODE > 41

l Your printer driver settings can override any settings from the

printer menu or printer front panel.

Before sending a file to the printer, many word processors send either an “initialization string” or an

I-Prime

signal to the printer.

The initialization string contains codes that override the panel and menu settings. To change your printer to ignore the reset code, enter the

This will print a line showing the emulation you have selected.

Problem

Ink smears on the paper when I print narrow columns.

Solution

This may be caused by excessive printhead travel from the centering position. Enter the Menu and set the Centring Position to

MODE 1

. See

“Using Your Printer, Menu Mode.”

For the wide carriage printer, if MODE 1 doesn't work, try setting the Centering Position to

MODE 2

Problem

I've installed a new ribbon and the printing is smeared and streaked.

Solution

The ribbon shield (1) is either loose or missing.

Remove the ribbon cartridge and check the ribbon shield.

If it is loose, secure it.

If it is missing, find it and install it.

TROUBLESHOOTING > 65

Problem

There are dots missing in my printouts.

Solution

The head gap may not be set correctly. Try moving the headgap lever to a lower setting. If that doesn’t help, the printhead may be damaged; call for service.

Problem

Continuous-form paper sticks to the sheet guide.

Solution

In cold dry weather, static charges can build up and make the paper cling to the sheet guide. Try moving the paper guides together so that the paper rests on the guides rather than on the separator.

Problem

The Print Quality and Character Pitch keys on the front panel don't work.

Solution

The Operator Panel Function in the printer menu can be used to disable these buttons (Limited Function). If the printer is part of a customized system or if it is used by a number of people, the system manager may have used this option to make sure the printer is always set properly.

Check with your system manager before changing any menu settings.
