Chapter 1 Overview and Basic Operations

Post-Printing Verification Settings

This product monitors dot missing periodically with the auto nozzle check system, and performs the auto
head cleaning if any dots are missing. Select from 6 modes that are available for different levels of
requirements for print quality and movement.
When extremely high reliability and safety are required, be sure to detect dot missing using an application
in addition to the printer driver setting. For the details, see "When Extremely High Reliability and Safety are
Required" on page 130.
Sets this function from [Post-Printing Verification Settings] on [Maintenance And Utilities] of the printer driver.
The printer's Post-Printing Verification Settings can be checked using Self-test Mode. For the details, see "Self-
test" on page 156.	1
• High Reliability Mode (Void Image Print)
Missing dots check is performed after printing each page to check that dot missing has not occurred.

When dot missing is detected, the Void Image Print is performed at the bottom of the previous page. And after the dot missing is resolved by the auto head cleaning, reprinting starts from the corresponding page.

The Void Image is printed in solid black by default; however, other image files can also be

registered. Since dots are missing for the page on which the Void Image is printed, take proper action such as discarding it.

•High Reliability Mode (Reprint)

Missing dots check is performed after printing each page to check that dot missing has not occurred. When dot missing is detected, the following screen of the EPSON Status Monitor 3 is displayed. Select the next operation from [Restart printing] (printing the next data) and [Reprint] (reprinting after dot missing is resolved by the auto head cleaning.)

•Economy Mode for Low Print Volume (Void Image Print)

Missing dots check is performed after printing each page with removing the timer cleaning.

When dot missing (more than neighboring 2 dots missing) is detected, the Void Image Print is performed

at the bottom of the previous page. And after the dot missing is resolved by the auto head cleaning, reprinting starts from the corresponding page.

The Void Image is printed in solid black by default; however, other image files can also be registered.

•Economy Mode for Low Print Volume (Reprint)

Missing dots check is performed after printing each page with removing the timer cleaning.

When dot missing (more than neighboring 2 dots missing) is detected, the EPSON Status Monitor 3 is

displayed. Select the next operation from [Restart printing] (printing the next data) and [Reprint] (reprinting after dot missing is resolved by the auto head cleaning).

When customer want to select this mode, do NOT uncheck [Use EPSON Status Monitor 3] of [Driver Preferences] in [Driver Utilities] tab.

•Anti-missing Read Mode

Does not perform missing dots check after printing each page, but checks missing dots while not printing.

•Anti-missing Color Mode

Does not perform missing dots check after printing each page, but checks missing dots while not printing. Prevents missing colors due to missing dots on the condition with adjoining 2 dots in above and below or 3 dots in all nozzles. Does not perform head cleaning to missing dots with less than 2 dots that are not adjoining.

These functions do not guarantee a 100 percent prevention of dot missing.Small amount of ink is used for detecting nozzle clogging.

The auto head cleaning is performed automatically after nozzle clogging is detected. Ink is expended during the head cleaning.

Nozzle clogging detect function cannot be disabled.

When you want to select [High Reliability Mode (Reprint)] or [Economy Mode for Low Print Volume (Reprint)], do not uncheck [Use EPSON Status Monitor 3] of [Driver Preferences] in [Driver Utilities] tab.

In the High Reliability Mode or Economy Mode for Low Print Volume, printing takes more time since the missing dots check is performed after printing each page.

When an unrecoverable missing dot occurs, the printer operates differently for each mode as shown below.

Printer Status	Fatal error	Maintenance error

	High Reliability Mode	High Reliability Mode
Post-Printing	Economy Mode for Low	Economy Mode for Low

Chapter 1 Overview and Basic Operations

When an Unrecoverable Missing Dot Occurs

When 1 dot of unrecoverable missing dot is detected with the Post-Printing Verification Settings for the printer driver set to the High Reliability Mode /Economy Mode for Low Print Volume /Anti-missing Read Mode, the printer becomes in fatal error status. To continue printing, turn off and on the printer and change the mode to the Missing Dot Acceptable Print Mode.

Missing dots check detects an unrecoverable missing dot.

A fatal occurs (page 56)

The operator turns off and on the printer.

The printer starts up in the Missing Dot Acceptable Print Mode

In the Missing Dot Acceptable Print Mode, it takes long to complete printing because missing dots check is performed after printing each page. The EPSON Status Monitor 3 appears each time of printing until the missing dot error is resolved. (The window may not appear depending on the printer driver version.)

In the Missing Dot Acceptable Print Mode, EPSON Status Monitor 3 is displayed even if [Use EPSON Status Monitor 3] is not selected in [Driver Preferences] from the [Driver Utilities] tab.

When 2 or more dots of unrecoverable missing dot is detected in the Missing Dot Acceptable Print Mode, maintenance is requested and the printer needs repair.

Basic Operations

This section describes the basic operation methods of the product that can be used by an operator and the general operations of the product.

To prevent operation errors, the button can be set so that it cannot be used to turn off the power.

This can be set in [Start]-[Control Panel]-[Power Options]-[Advanced]-[Power buttons].

Do not turn off the power using the commercial circuit breaker. The printer's power off sequence will not be executed and the ink may become clogged.

If the power is cut off due to an outage, etc., turn on/off the power of the product after the power is restored.

Turning On/Off the Power of the Printer

It is possible to specifically control the power of the printer portion of the product. While the product is operating, by turning on/off the printer only when you need to print, it is possible to reduce the standby power consumption.

The power status of the printer can be verified using the "Printer Power ON/OFF" utility.

An API is available for turning on/off the power of the printer using the customer's application. (See "TM-C3400-LT Reference Library" on page 125)

There is no power lamp for the printer.

When the power button is pressed, the power of the main unit and the printer will turn on together. (default setting)

If Windows is running, turn on the printer using the "Printer Power ON/OFF" utility. Double-click TMC34LT_POWER on the desktop.

Press the On button. When the power of the printer turns on, the power status of the printer will change to green.

Turning Off the Printer

When the printer is turned off, the printer's power off sequence will be executed, the fan will operate for several seconds, and the power will turn off.

Press the Off button in the "Printer Power ON/OFF" utility. The power status of the printer will change to gray.

Printer status

The Printer Status utility monitors the printer's status, and when an error or warning condition occurs, it is displayed on the screen.

After confirming the error/warning, press the [Close] button to close the screen.

When the printer is in a normal state, the "Printer Status" will not be displayed.

It is also possible to display the printer status display utility from "TMC34LT_UTIL” on the desktop.

The ink level can be verified using the Printer Status utility.

When the ink level becomes low, and it is almost time to replace the ink cartridge, a message will be displayed onscreen. Prepare a new ink cartridge.

When it becomes time to replace the ink cartridge, a message will be displayed onscreen and the product will stop printing. You will not be able to print until you install a new ink cartridge.

The ink cartridge that is shipped with the product is for initial ink charging. When an ink cartridge is installed for the first time (during setup), ink will be consumed for ink charging, and you will need to replace the ink cartridge earlier than usual.

The amount of ink consumed will vary depending on the use environment and use conditions of the product.

To preserve the quality of the print head, it will become time to replace the ink cartridge before the ink in the cartridge is completely used up.

The ink cartridge contains 3 colors of ink. Even when one particular color is specified, all 3 colors of ink are used for printing and for keeping the print head in good condition. When the ink level of even one color comes to the lowest limit, the product stops printing.

Ink Cartridge Replacement Procedure

See "Loading the Ink Cartridge" on page 46. The same procedure can be used for replacing the cartridge. Pull out and remove the used ink cartridge.

For the ink cartridge model, see "Ink Cartridge" on page 199.
