Safety Instructions

When handling the ink cartridges

❏ Keep ink cartridges out of the reach of children

and do not drink.

❏ If ink gets on your skin, wash it off with soap and

water. If it gets in your eyes, flush them immediately with water.

❏ Before installing the new ink cartridge in the

printer, shake it horizontally as shown in the illustration. Shake it back and forth horizontally in five centimeter movements about 100 times within 30 seconds for white, and about 15 times within five seconds for all other cartridges.

❏ If you remove an ink cartridge for later use,

protect the ink supply area from dirt and dust, and store it in the same environment as this product. Note that there is a valve in the ink supply port, making covers or plugs unnecessary, but care is needed to prevent the ink from staining items that the cartridge touches. Do not touch the ink supply port or surrounding area.

When transporting this product

❏ Before transporting the printer, make sure the

print heads are in the home (far right) position.

Illustrations used in this guide

❏ The illustrations in this guide are from a similar

Caution:

Do not shake cartridges (that have been installed previously) with too much force.

❏ Use the ink cartridge before the date printed on

its package.

❏ Use up the ink cartridge within six months of

installation for best results.

❏ Do not dismantle the ink cartridges or try to refill

them. This could damage the print head.

❏ Do not touch the green IC chip on the side of the

cartridge. This may affect normal operation and printing.

❏ The IC chip on this ink cartridge retains a variety

of cartridge-related information, such as the ink cartridge status, so that the cartridge may be removed and reinserted freely. However, each time the cartridge is inserted, some ink is consumed because the printer automatically performs a reliability check.

Epson Stylus Pro WT7900/7910 User’s Guide

Introduction

See “Shaking a White Ink Cartridge” on page 65

Automatic maintenance feature

This product is wide-format ink jet color printers that provide a white ink printing feature, supporting 24-inch paper. Read this section before using your printer.

White Ink Printing

In addition to normal color printing, white printing onto a transparent film is also possible by using a combination of newly developed white ink and Epson ClearProof Film (Epson special media). This allows you to use transparent films for your pre-press workflow and color proofing.

Epson ClearProof Film

Epson ClearProof Film requires a specific operating environment and handling method that differs from using traditional Epson special media. Follow the instructions that come with the media.

Auto white ink refresh

Automatically refreshes old white ink with new ink to avoid sedimentation in the ink tube.

See “White ink refresh” on page 78

See “Auto white ink refresh function” on page

Ink changing to protect the print head

Automatically changes white ink to cleaning liquid in the print head when powering off. Cleaning liquid prevents ink sedimentation in the print head. It cannot be used for printing or cleaning outside the printer. Turn off your printer if it will not be used for a long period of time, for example during nighttime hours or weekends.

See “Cautions when powering off” on page 9

See “MAINTENANCE” on page 25

See “About Epson ClearProof Film (Epson special

media)” on page 59

White Ink Maintenance

Sedimentation (ink components settle to the bottom of liquid) may be caused when using white ink. Continuing to use white ink when sedimentation has occurred may result in reduced print quality or printer failure. To avoid white ink sedimentation, you need to manually maintain the white ink as well as allowing the printer to perform automatic white ink maintenance.

User maintenance

Shaking the white ink cartridge

You must shake the white ink cartridge periodically to avoid sedimentation in the ink cartridge.

See “Maintaining White Ink” on page 63

See “Notes for storing white ink cartridges” on

page 65

Cautions when powering off

When not using your printer for a long period of time, sedimentation of the white ink may occur in the print head nozzle, which may cause problems such as printer failure. To avoid such problems, the printer automatically changes white ink to cleaning liquid in the print head when powering off. Make sure you follow the instructions below when turning off your printer.

❏ Always use the

Ink changing (auto) is not possible if you turn off your printer by unplugging the printer cable, or cutting the power at a distribution switchboard or circuit breaker.

❏ Do not unplug or operate a distribution

switchboard or circuit breaker until the LCD panel display switches off after pressing the button. Ink changing takes two to three minutes. Wait for a while until the ink changing procedure finishes and your printer is completely turned off.

button on the control panel.

Epson Stylus Pro WT7900/7910 User’s Guide

Caution:

If an unexpected power-off is triggered by electrical power failure or a short circuit, you must turn on your printer and then turn it off again by pressing the Power button.

❏ Make sure that there is enough cleaning liquid

remaining when powering off. Both white ink and cleaning liquid is required for the ink changing procedure. The printer turns off without changing ink if there is not enough cleaning liquid remaining. Prepare extra cleaning cartridges in advance.

Instructions for Using Paper

Notes for handling paper

See the instructions below and the handling instructions supplied with the paper for more details.

❏ Use Epson special media under the following

conditions (temperature: 15 to 25˚C and humidity: 40 to 60%). In particular, use Epson ClearProof Film under the following conditions (temperature: 20 to 25˚C and humidity: 40 to 60%).

See “About Epson ClearProof Film (Epson

special media)” on page 59

❏ Do not bend the paper or scratch on the surface

of the paper.

❏ Keep fingers off the printable surface of the

media, as fingerprints may reduce the print quality.

❏ Set the roll paper by handling the edges of the roll

paper. Whenever possible, use gloves to handle media.

❏ Do not use a dryer to dry the printouts.

❏ Avoid direct sunlight.

❏ See the instructions of the paper for keeping the

color from fading. The print can keep the color for a long time if you store it properly.

Note:

Typically, prints and photos fade over time (change color) due to the effects of light and various constituents in the air. This also applies to Epson special media. However, with the correct storage method, the amount of color change can be kept to a minimum.

❏ See the instructions included with the Epson

special media for detailed information on handling the paper after printing.

❏ The colors of photos, posters, and other printouts

appear different under different lighting conditions (light sources*). The colors of printouts from this printer may also appear different under different light sources. * Light sources includes sunlight, fluorescent light, incandescent light, and other types.

❏ The paper may bend if the temperature and

humidity will change rapidly. Be careful not to bend or soil the paper, and flatten it before setting it in the printer.

❏ Do not lose the paper package so that you can use

it for storing the paper.

Notes for after printing

See the instructions below for after printing.

❏ Do not rub or scratch the print; otherwise, the ink

may come off.

❏ Do not touch the surface of the print; otherwise,

the ink may come off.

❏ Be careful not to bend or pile paper on top of

another, and dry it completely. The color may be changed where the paper is piled. If you leave paper lying on top of another, the scratches may stay on the paper even after the paper dries.

Notes for storing the paper

See the instructions below and the handling instructions supplied with the paper for more details.

❏ Avoid locations that are subject to direct sunlight,

excessive heat, or moisture.

❏ Keep the paper in the package and keep it on a flat

surface.

❏ Remove roll paper that is not in use from the

printer. Roll it properly and then store it in the original packaging. If you leave the roll paper in the printer, its quality will deteriorate.

❏ Do not wet the paper.

❏ Store printouts in a dark place to avoid direct

sunlight, excessive heat, and moisture to retain the printed color.

❏ If you put the prints on the album before they dry,

they may be blurred. After you print, be sure to dry the paper completely.

Paper Information

About Epson ClearProof Film (Epson special media)

Pay careful attention to the following important notes for using Epson ClearProof Film. Refer to the instructions included with the media for more details.

Usage Environment

This media requires a limited environment for use. Temperature: 20 to 25 ˚C Humidity: 40 to 60 % Avoid direct sunlight, high temperature, and high humidity. To maintain quality, maintain this environment for after printing. Otherwise white ink may appear to change color due to the humidity.

About Release Film

Notes for Setting up Media

❏ Cut off the edge of the media in a straight line if

the conditions of the edge are as follows. Otherwise the media may jam inside the printer or print quality may decline. 1. The edge of the media is wrinkled 2. The media is folded, bent, wavy, or warped. 3. The release film is separated.

❏ When printing on Epson ClearProof Film after

printing on anything other than Epson ClearProof Film, clean the inside of the printer and the roller if they are smeared. Otherwise paper powder remaining inside the printer may stick to the printing surface and scratch the surface when wiped.

Notes for After Printing

❏ Do not touch the printing surface immediately

after printing is complete. Otherwise ink may come off and blotches may remain.

There is a white release film on the reverse of this media. Do not remove the release film until printing and drying is complete. This film protects the media from damage and prevents dust adhering during printing. Note the following usage points.

❏ Do not load the media into the printer after

removing the release film. Otherwise the surface of the media may be scratched and stained.

❏ Remove the release film slowly and carefully after

thoroughly drying the print surface. If it is not completely dry, the print surface may be folded or bent and defects may remain. If the release film is removed with too much force, part of the film may remain and this will be difficult to remove.

❏ Static electricity is generated when removing the

release film. Keep away from delicate instruments when removing, and touch a metal object to remove the static after removing the film.

❏ Do not wet the printed media. Otherwise water

stains may remains.

❏ Do not laminate the printed media. Otherwise

white ink becomes transparent.

❏ The minimum media length when using auto cut

is 420 mm. Cut manually if you want to cut a length less than 420 mm.

See “Cutting the roll paper after printing” on

page 36

❏ Make sure you do not stick the film on the

printing surface. Otherwise ink may come off or the surface may be scratched.

Maintenance

Daily Maintenance

Maintenance

❏ If you have not printed for a while, turn the

printer on once a month and execute PRINT WITH WHITE INK from NOZZLE CHECK on the control panel. This can prevent sedimentation in the nozzles.

See “Nozzle check” on page 75

Instructions for placing the printer

Observe the following when setting up the printer:

❏ Choose a flat and stable location that can support

the printer weight (about 103 kg).

❏ Use only an outlet that meets the power

requirements of this printer.

❏ Leave enough room for easy operation,

maintenance, and ventilation.

See "Choosing a place for the printer" in the

Setup Guide

❏ Operate the printer under the following

conditions (temperature is 10 to 35˚C and humidity is 20 to 80%).

Even when the conditions above are met, you may not print properly if the environmental conditions are not proper for the paper. Be sure to use the printer where the paper conditions are met. See the handling instructions of the paper for more detailed information. Keep the printer away from drying, direct sunlight, or heat sources to maintain the appropriate humidity.

Notes for when you are not using the printer

The print head nozzles are very small, thus, they can become clogged easily if dust gets on the print head. To avoid this, close the roll paper cover or the front cover when you are not using the printer. If you are not using the printer for a long time, put a non-static cloth on the printer to avoid getting dust on the printer.

About ink cartridges

Maintaining White Ink

Due to the properties of the white ink, sedimentation can occur. To maintain optimum printing conditions, make sure you periodically perform the following maintenance procedure.

❏ Turn the printer on once a week and shake the

white ink cartridge. This can prevent sedimentation in the white ink cartridge.

Notes for handling the ink cartridges

❏ When INK LOW appears on the LCD panel,

replace the cartridges with a new one as soon as possible to avoid ink to being expended while printing.

❏ Use up the ink cartridge within six months of

installation for best results.

❏ If you move the ink cartridge from the cold place

to warm place, condensation may occur. Leave it at room temperature for more than four hours before using the ink cartridge.

❏ We recommend using an ink cartridge by the

expiry date printed on the cartridge carton. If you use an ink cartridge after the expiry date, print quality may be affected.

❏ Store ink cartridges under the same condition as

the printer.

❏ Do not touch the ink supply port or its

surrounding area. The ink may leak from it.

❏ Do not touch the green IC chip on the side of the

ink cartridge. Doing so may affect normal operation and printing.

❏ Because the green IC chip has the cartridge’s own

information and the ink remaining information, you can still use the ink cartridge after pulling out the ink cartridge from the printer.

❏ Do not disassemble or remodel the ink cartridge,

otherwise you may not be able to print normally.

❏ Do not drop or knock it against hard objects;

otherwise, the ink may leak.

Notes for replacing ink cartridges and shaking the white ink cartridge

❏ To maintain optimum printing conditions, shake

the ink cartridge with referring to the sections below.

See “Shaking the White Ink Cartridge” on

page 66

See “Replacing ink cartridges” on page 68

❏ Do not leave the printer without ink cartridges

installed. The inks inside the printer may dry and you may not be able to print.

❏ Install all ink cartridges. You cannot print if any

of the slots are empty.

❏ Make sure that the printer is turned on when you

replace an ink cartridge or shake a white ink cartridge. If the printer is turned off while replacing an ink cartridge or shaking a white ink cartridge, the amount of ink remaining is not detected correctly and you cannot print properly.

❏ Be careful as there is ink around the ink system

port on the used ink cartridge.

❏ To ensure you receive premium print quality and

to help protect your print head, a variable ink safety reserve remains in the cartridge when your printer indicates to replace the cartridge.

Notes for storing the ink cartridges

❏ Store ink cartridges under the same condition as

the printer (temperature is 10 to 35˚C and humidity is 20 to 80%).

❏ Although nothing may be printed, the printer

uses ink from all cartridges during head cleaning and other maintenance operations to keep the print heads in good condition.

❏ Although the ink cartridges may contain recycled

materials, this does not effect printer function or performance.

❏ Ink cartridges that are removed before ink is

expended can be reinstalled in the printer and used again if the expiry date printed on the ink cartridge packaging has not passed. Avoid getting dirt on the ink system port and store the removed ink cartridge properly. You do not need to put the ink cartridge in the package. The ink system port has a valve in it so you do not need to put a cap on it; however, be careful not to tamper with the ink system port.

Notes for storing white ink cartridges

Note the following if you do not use white ink cartridges directly after purchase and store them for a long time.

❏ Before storing, shake the box with the white ink

cartridge inside quickly back and forth horizontally in roughly five centimeter movements, about 100 times within about 30 seconds.

❏ Lay the cartridge down flat. If you store the

cartridge vertically, you may not be able to clear white ink sedimentation even after performing maintenance.

❏ Every one month, shake the box with the white

ink cartridge inside quickly back and forth horizontally in about five centimeter movements, over 10 times.

When the message appears on the LCD panel

When the white ink cartridge needs shaking, a message appears on the LCD panel. Also, the date at the bottom of the LCD panel showing the days remaining until you next need to shake the white ink cartridge. You can continue printing even if the message is displayed, but we recommend that you shake the white ink cartridge to maintain the best print quality.

Shaking a White Ink Cartridge

Due to the properties of the white ink, sedimentation can occur. To maintain optimum printing conditions, make sure you remove and shake the cartridge once a week, even if it is installed in the printer.

Checking the days remaining until next you need to shake the cartridge

The LCD panel shows the days remaining until the next white ink maintenance is required.

See “Display” on page 15

Note:

If a month passes without shaking, a warning message is displayed and you cannot print. When this happens, shake the white ink cartridge to clear the error.

Furthermore, the automatic head cleaning is performed the number of times you set on the control panel; one time for the default setting or three times (maximum) until the clogged nozzles are cleared. However, after manual head cleaning, the automatic head cleaning is performed once in spite of the settings on the control panel.

Capping function

Capping is a function for automatically covering the print head with a cap (lid) to prevent the print head from drying out. Capping is performed in the following situations.

❏ When several seconds have elapsed after printing

finishes (that is there is no print data sent).

❏ When printing is stopped.

Take care of the following points to ensure that the print head is capped properly.

❏ If the print head is not positioned on the right

side (it is not capped), turn the printer on, then off again. By turning the printer off with the button, the head is capped properly.

AUTO NOZZLE CHECK function

The printer performs a nozzle check without printing a pattern and detects the clogged nozzles automatically. If there are missing dots, it performs cleaning automatically (taking two to 12 minutes).

When the AUTO NOZZLE CHECK function is ON, it works in the following cases:

❏ After the initial ink charging is completed.

❏ After head cleaning.

❏ After changing the white ink and the cleaning

required.

❏ When printing is started.

❏ If you turn the power off when a paper jam or

error occurs and the print head is not capped, turn the printer on again. Shortly, the print head is capped automatically. Check that it is properly capped, then turn the printer off.

❏ Do not move the print head manually under any

circumstances.

❏ Do not remove the power plug of the printer or

cut the power at the circuit breaker when the power is on. The head may not be capped properly.

the platen, use something like a toothpick to remove it.

Keeping the Printer

When storing the printer, place it on a horizontal surface with the ink cartridges installed in the printer.

Caution:

The printer must be kept flat. Do not tilt it, stand it on end, or turn it upside down.

If you do not use your printer for a long time

❏ If you do not use your printer for a long time, the

print head nozzles may become clogged. We recommend that you print regularly to prevent clogging. Also, turn on the printer at least once a month, and leave it on for a few minutes.

❏ Do not leave the printer without ink cartridges;

otherwise, the ink will dry out and the printer is not able to print properly. Even if you do not use the printer, leave all of the ink cartridges in the slots.

❏ Do not leave the paper in the printer for a long

period of time; otherwise, the roller for securing the paper may leave a mark on the surface of the paper.

Maintenance

If you do not use your printer for more than a month

❏ If you do not use your printer for a long time,

execute white ink maintenance.

See “Maintaining White Ink” on page 63

❏ When activating AUTO NOZZLE CHECK in the

panel settings, the printer checks the print head nozzles for clogging, and performs print head cleaning automatically if needed.

❏ If you have not used your printer for a long time,

print a nozzle check pattern to check for clogging. If the nozzle check pattern is not good, perform head cleaning before printing your data.

See “Nozzle check” on page 75 See “Head cleaning” on page 77 See “Power cleaning” on page 78

❏ You need to perform head cleaning a few times

before the nozzle check pattern is correctly printed. If the nozzles are still clogged after performing head cleaning three times, perform power cleaning.

See “Head cleaning” on page 77 See “Power cleaning” on page 78

If you do not use your printer for more than a year

If you do not use your printer for more than a year, the white ink may be clogged in the print head and ink tube. If the print head and the ink tube are still clogged after executing POWER CLEANING and WT INK REFRESH, contact your local Epson dealer/ representative.

See “Power cleaning” on page 78

See “White ink refresh” on page 78

Protecting the print head

This printer has a capping function that automatically puts a cap on the print head to keep it away from drying. If the print head is left uncapped, the print quality may decline. When you are not using the printer, make sure the print head is located on the far right so that it is capped.

See “Capping function” on page 79

❏ After performing the head cleaning a few times,

turn off the printer and leave it overnight or longer, so that the ink may dissolve.

❏ If the nozzles are still clogged after trying the

instructions above, contact your Epson dealer.

Troubleshooting

You cannot print (because the printer does not work)

Cause What to do

The printer does not turn on.

The printer is not correctly connected to the computer.

Is the power cord plugged into the electrical outlet or the printer?

Make sure the power cord is securely plugged into the printer.

Is there any problem with the electrical outlet?

Make sure your outlet works by trying to connect the power cord of another electric product.

Is the cable plugged properly?

Make sure the printer’s interface cable is securely plugged into the correct terminal of the computer. Also, make sure the cable is not broken nor bent. If you have a spare cable, try with the spare cable.

Does the interface cable specification match the specifications for the computer?

Make sure the interface cable specifications match the specifications for the printer and computer.

See “Interface” on page 114

Is the interface cable directly connected to the computer?

Make sure the interface cable is directly connected to the computer without passing through any device, such as a printer switching device, or extension cable.

When using a USB hub, is it being used correctly?

In the USB specification, daisy-chains of up to five USB hubs are possible. However, we recommend that you connect the printer to the first hub connected directly to the computer. Also, some hubs may cause unstable operation. If problems occur, connect the printer directly to the USB port of the computer.

Is the USB hub recognized correctly?

Make sure the USB hub is recognized correctly in the computer. If the USB hub is recognized correctly, unplug all of the USB hubs from the computer’s USB port, and then connect the printer’s USB connector directly to the computer’s USB port. Ask the USB hub manufacturer about USB hub operation.

Printing is not available under a network environment.

The printer has an error.

Are the network settings correct?

Ask your network administrator for the network settings.

Connect the printer directly to the computer using a USB cable, an d then try to print.

If you can print via USB, there are some problems with the network environment. Ask your system administrator, or refer to the manual for your network system. If you cannot print, see the appropriate section in this manual.

Confirm if errors have occurred in the printer by checking the lights and messages on the printer’s control panel.

The printer sounds like it is printing, but nothing prints

Cause What to do

The print head moves, but nothing prints.

The nozzle check pattern is not printed correctly

Cannot print with white ink

If the print head moves, but nothing prints, confirm the printer operation.

Print a nozzle check pattern. You can check the printer’s operation and status without connecting the printer to the computer.

See “Nozzle check” on page 75

If the print head moves, but nothing prints, make sure MOTOR SELF ADJUSTMENT is displayed on the LCD panel.

The printer adjusts the motor inside of the printer. Please wait without turning off the printer. After about three minutes, the printer returns to normal operation.

Are the print head nozzles clogged?

If the nozzles are clogged, the print quality is reduced. Clean the print head and then print the nozzle check pattern again.

See “Head cleaning” on page 77

If the nozzle check pattern has missing dots, perform a print head cleaning.

If you replace the ink cartridges while the printer is turned off, the remaining amount of ink cannot be detected correctly so that the Ink Check light does not come on even when the ink cartridge needs to be replaced; otherwise you cannot print correctly. Be sure to follow the instructions in this manual to replace the ink cartridge.

See “Replacing Ink Cartridges” on page 68

Has the printer not been used for a long time?

If the printer has not been used for a long time, the nozzles dry up and may be clogged. See the following section.

See “If you do not use your printer for more than a year” on page 85

Are the print head nozzles clogged?

If the nozzles are clogged, print quality is reduced. Execute head cleaning and then print a nozzle check pattern. If the nozzles are still clogged, try power cleaning or white ink refresh and then print the nozzle check pattern again.

See “Head cleaning” on page 77 See “Power cleaning” on page 78 See “White ink refresh” on page 78

Has the printer not been used for a long time?

When not using your printer for a long time, sedimentation of the white ink may occur in the print head nozzle, and then the nozzles may be clogged. See the following sections for more information on what to do if you have not used your printer for a long time.

See “If you do not use your printer for more than a month” on page 85 See “If you do not use your printer for more than a year” on page 85

Epson Stylus Pro WT7900/7910 User’s Guide

Problem Solver

The prints are not what you expected

Cause What to do

Print quality is poor, uneven, too light, or too dark.

Are the print head nozzles clogged?

If the nozzles are clogged, the print quality is reduced. Print the nozzle check pattern.

See “Nozzle check” on page 75

Is there any gap in the print head during bidirectional printing?

With bidirectional printing, the print head prints while moving left and right. If the print head is misaligned, ruled lines may be printed misaligned with gaps. If vertical ruled lines are misaligned with bidirectional printing, adjust the gap.

See “Print head alignment” on page 80

Are you using a genuine Epson ink cartridge?

If you use the non-genuine Epson ink cartridges, printouts may smear, or the color of the printed image may be changed because the ink remaining is not correctly detected. Be sure to use the correct ink cartridge.

Are you using an old ink cartridge?

Print quality decreases when an old ink cartridge is used. Replace the old ink cartridge with a new one. Be sure to use the ink cartridge before the expiry date (within six months after installing to the printer).

Does the Auto white ink refresh turn off?

If AUTO WT INK REFRESH is turned off, printouts may have uneven results depending on the printing frequency. When the white ink density is uneven, execute the WT INK REFRESH.

See “White ink refresh” on page 78

Has the printer not been used with white ink for a long time?

If the printer does not use the white ink for a long time, white ink sedimentation is not cleared even if AUTO WT INK REFRESH is turned on. In this case, execute WT INK REFRESH.

See “If you do not use your printer for more than a year” on page 85

Print quality is poor, uneven, too light, or too dark.

Did you open the front cover during printing?

If the front cover is opened during printing, the carriage stops suddenly causing unevenness in the color. Do not open the front cover during printing.

Does INK LOW appear on the LCD panel?

Print quality may decrease when the ink is nearly expended. Replace the ink cartridge with a new one. If the print quality is not good after replacing the ink cartridge, perform head cleaning a few times.

The print is not positioned properly on the paper.

Left/right ruled lines are bumpy.

Have you specified the print area?

Check the print area in the settings of the application and printer.

Is the paper size setting correct?

If the PAPER SIZE setting and the size of the actual paper do not match, the print may not be where you want it, or part of it may be cut off. In this case, check the print settings.

Is the paper skewed?

If PAPER SKEW CHECK in the panel settings is OFF, the paper is printed even if it is skewed. In this case, the print will not be in the print area. Set PAPER SKEW CHECK to ON in the Menu mode.

See “PRINTER SETUP” on page 22

Does the print data fit within the paper width?

If the print image is bigger than the paper width, printing normally stops. However, if the PAPER SIZE CHECK is OFF, the paper is printed even if the paper width is exceeded. Set PAPER SIZE CHECK to ON in the Menu mode.

Is the roll paper margin set to 15 mm or 35 mm?

When using auto rotation, or when printing to the full width of the paper (for example, printing at A2 horizontal size on 24-inch wide roll paper), if the ROLL PAPER MARGIN is set to 15 mm or 35 mm, the data extends beyond the print area on the right side of the paper is not printed. Set the ROLL PAPER MARGIN to 3mm.

See “PRINTER SETUP” on page 22

Is the print head misaligned (leaving gaps)? (during bidirectional printing)
