Sets whether to detect the paper width or not. Setting to OFF deactivates the sensor that detects the paper width when paper is loaded on the printer. This allows the user to use paper whose width is out of the sensor’s detectable range. It means that the user can print an image larger than the paper size. The user should know that doing so soils the platen and may cause a print quality or any other trouble.

Sets whether to detect the paper skew or not. Setting to OFF does not carry out the detection and printing is continued even if the paper is skewed. When this setting is set to OFF, the user should have known the risk. This setting is not available for cut sheet because the skew detection function after printing is not provided for cut sheet.

When this is set to ON, the top edge area of paper soiled by the previous borderless printing is automatically cut off.

The printer runs a nozzle check automatically at the specified timing.ON: EVERY JOB

used. When the set number of pages is reached, the nozzle check pattern is printed on the top of the page. The counter for counting the pages is not reset even by power-off.When this setting is changed, the counter is cleared. Printing patterns preset in the printer is not counted except the network status sheet.

2.3 Ink Supply Mechanism

The ink supply mechanism consists of the Ink Cartridge, Ink Holder, and Pressure Pump Unit.

 Ink Cartridge

This is the cartridge that contains ink, and equipped with the CSIC that stores the information on detecting attachment of the cartridge, the type of ink and life etc.

 Ink Holder

This is the holder that the Ink Cartridges are installed and relays the connection between the Ink Cartridges and the Ink Tubes/Pressure Pump Tubes.

 Pressure Pump Unit

This is the unit to stabilize the supply of ink from the Ink Cartridge (Ink Pack) to the printhead. The ink stored in the Ink Pack is supplied to the printhead by sending the air from the Pressure Pump Unit to the sealed Ink Cartridge so as to apply pressure to the Ink Pack.

2.4 Cleaning Mechanism

The cleaning mechanism consists of the Maintenance Tanks, the Ink System Unit and the AID function.

 Maintenance Tank

This is the tank that retrieves (absorbs) the waste ink. This printer is equipped with three Maintenance Tanks.

• HP side:

for the waste ink at capping, flushing, and borderless-printing of less than 24 inch

• Center:

for the waste ink at borderless-printing of over 728 mm to 44 inch

• Left side (opposite to HP):

for the waste ink at borderless-printing of over 44 inch

 Ink System Unit

The Ink System Unit consists of the Cap, Flushing Box, Wiper, Pump, and the Carriage Lock. The positions of these parts are changed by the drive of the Cap/Wiper Motor. The control of this positioning change is monitored by the Cap Unit HP Sensor.

 Cap Unit

This is the unit that protects the nozzle surface of the printhead. It is equipped with five caps and each cap is used for every two rows of nozzles.

 Pump

This is the unit to suck ink from the nozzles. It is driven by the Pump Motor.

 Carriage Lock

This is the part that locks the Carriage Unit. It is driven by the Cap/Wiper Motor.

Flushing Box

Wiper

Pump

 Flushing Box

This is the box to receive ink at flushing. The box is mobile and stored at the rear of the Ink System Unit when unused. When in use, it is automatically moved to the specified position by the Cap/Wiper Motor.

Carriage Lock

 Wiper

This cleans the nozzle surface of the printhead by wiping it. The Ink System

Cap Unit

Unit is equipped with two wipers (the one for all nozzles and the other for one nozzle).

Stylus Pro 11880/11880C Revision B

 AID (Auto Ink droplet Detection) Function

This is the function that detects the dot-missing automatically. Voltage is applied to the Flushing Box from the DC-DC converter on the AID Board (BOARD ASSY.,HEAD). This voltage application generates the electric field at the space between the nozzle

Flushing Box

plate of the printhead and the Flushing Box. The ink discharged from the nozzles is electrically charged while dropping through the generated electric field. Since the ink is charged, the landing of the drop of ink on the Flushing Box can be detected electrically. Discrimination of the nozzles with dot-missing becomes possible, since whether the discharged drop of ink lands or not can be detected by each nozzle level. In the case that dot-missing occurs, the cleaning is executed automatically.

The mechanism that moves the carriage is explained below. The carriage movement mechanism consists of the following components:

 Carriage Unit

 CR Motor

 Timing Belt

 CR Scale

 CR Encoder Sensor

 CR HP Sensor

 PG HP Sensor

Rotational drive of the CR Motor is transmitted to the Carriage Unit through the Timing Belt, and the Carriage Unit is moved left and right along the carriage guide shaft. The CR Encoder Sensor installed on the back of the Carriage Unit reads the jagged surface of the CR scale and sends the read values to the Main Board Assy. The control of the position and the speed of the Carriage Unit are based on these read values.

2.5.2 Platen Gap Adjustment Mechanism

The platen gap adjustment mechanism consists of the PG Motor, the Carriage Unit, and the PG HP Sensor. The drive of the PG Motor rotates the PG switching cam of the Carriage Unit through the driven gears. Lifting or lowering the Carriage Unit by this rotation of the PG switching cam adjusts the platen gap. The adjusting movement of the PG switching cam (PG positions) is controlled with the PG HP Sensor by detecting the rotation of the actuator mounted on the same shaft as the cam.

2.7 Other Mechanisms

 Front Cover Opening/Closing Detection Sensors

These sensors are mounted on both sides of the printer to detect the opening/closing status of the Front Cover. When either of the sensors detects the opening status of the cover, the CR Motor stops.

 Ink Mark Sensor

This is a reflective photo interrupter with a sender and a receiver mounted on the bottom surface of the Carriage Unit. The light emitted from the white LED reflects on the paper or the printed special pattern on the paper. The receiver of the sensor reads the reflected light, and the printer processes the correction based on the read data. The functions of the Ink Mark Sensors are listed below.

 Auto Bi-D adjustment

Acquires the value of the Bi-D correction automatically by detecting the peak block of relative density from the printed special adjustment patterns.

 Auto Uni-D adjustment

Acquires the value of the Uni-D correction automatically by detecting the peak block of relative density from the printed special adjustment patterns.

 Detection of the remaining amount of the roll paper

Checks the remaining amount of the roll paper by scanning the bar-code printed on the paper.

2.8 Colorimetric Calibration (Color ID) Overview

This printer employs “Colorimetric Calibration (Color ID)” to correct unit-to-unit variations in color. Colorimetric Calibration (Color ID) corrects not only the weight of ink droplets which differs depending on the individual characteristics of printhead but also variable factors such as drive circuit and voltage. This enables a higher-accuracy calibration.

OVERVIEW

1. Printing/ Measuring the color of a correction pattern A correction pattern printed by a completed product is used for the calibration. A calibrator is used to perform the color measurement of the printed pattern.

2. Writing the correction value Correction values are automatically calculated based on the result of the color measurement and stored in the NVRAM on the main board.

3. Reflecting the correction value Every time the printer makes a print, the printer driver reads out the correction values from the NVRAM. Each ink droplet weight and the number of ink droplets for each dot are corrected according to the information.

DISASSEMBLY & ASSEMBLY

CHAPTER

Page 76

EPSON Stylus Pro 11880/11880C Revision B

4.1 Overview

This chapter describes procedures for disassembling the main components of EPSON Stylus Pro 11880/11880C. Unless otherwise specified, disassembled units or components can be reassembled by reversing the disassembly procedure.

 WARNING

Procedures which, if not strictly observed, could result in personal injury are described under the heading “WARNING”.

 CAUTION

“CAUTION” signals a precaution which, if ignored, could result in damage to equipment.

 CHECK POINT

Important tips for procedures are described under the heading “CHECK POINT”.

 REASSEMBLY

If the assembly procedure is different from the reversed disassembly procedure, the correct procedure is described under the heading “REASSEMBLY”.

 ADJUSTMENT

Any adjustments required after reassembly of components or parts are described under the heading “ADJUSTMENT REQUIRED”. Be sure to perform the specified adjustments with reference to Chapter 5 “ADJUSTMENT”.

When you have to remove any parts or components that are not described in this chapter, refer to “7.2 Parts List” (p245) in the Appendix.

4.1.1 Precautions

Before starting the disassembly or reassembly of the product, read the following precautions given under the headings “WARNING” and “CAUTION”.

W A R N I N G

 When the Front Cover is opened, a safety-interlock mechanism

causes the CR motor and the PF motor to stop. Never disable the interlock function for operator protection.

 This printer is equipped with a lithium battery. When handling

the lithium battery, the following precautions should be followed.

• When replacing the battery, replace only with a specified

type of battery. Using a different type of battery may cause excess heat or explosion.

• Dispose of used batteries according to manufacture’s

instructions and local regulations. Contact your local government agency for information about battery disposal and recycling.

• When disposing of the battery, be sure to securely cover its

(+) end with tape to prevent combustion or explosion.

• Do not recharge the battery.

• Do not use the battery if it is discolored or damaged, or if any

leakage of electrolyte is observed.

• Do not dismantle, solder or heat the battery. Doing so could

result in leakage of electrolyte, heat generation, or explosion.

• Do not heat the battery or dispose of it in fire.

• If the electrolyte leaked from the battery contacts with your

skin or gets into your eyes, rinse it off with clean water and see a doctor immediately.

 The power switch is installed on the secondary side of the

power circuit, so power is always supplied unless the power cord is unplugged. Unless otherwise stated, be sure to unplug the power code before disassembling or assembling the printer to prevent electric shock and damage to the circuit.

DISASSEMBLY & ASSEMBLY Overview 76

Page 77

EPSON Stylus Pro 11880/11880C Revision B

W A R N I N G

C A U T I O N

 Always wear gloves for disassembly and reassembly to avoid

injury from sharp metal edges.

 If ink gets in your eye, flush the eye with fresh water and see a

doctor immediately.

 Never touch the ink or wasted ink with bare hands. If ink comes

into contact with your skin, wash it off with soap and water immediately. If irritation occurs, contact a physician.

 Make sufficient work space for servicing.  Locate the printer on a stable and flat surface.  The ink-path-related components or parts should be firmly and

securely reinstalled on the printer to prevent the ink from leakage.

 Use only recommended tools for disassembly, assembly or

adjustment of the printer.

 When using compressed air products; such as air duster, for

cleaning during repair and maintenance, the use of such products containing flammable gas is prohibited.

 Apply lubricants and adhesives as specified.  Be careful not to soil the printer or the floor with the leaked ink

when removing the ink-path-related components or parts. Spread a sheet of paper or cloth on the floor in advance.

 Do not touch electrical circuit boards with bare hands as the

elements on the board are so sensitive that they can be easily damaged by static electricity. If you have to handle the boards with bare hands, use static electricity discharge equipment such as anti-static wrist straps.

 When reassembling the printer, make sure to connect the

connectors of the electric components or parts correctly and securely. Use extreme care when connecting FFCs (flexible flat cables). Improper connection of the FFCs, such as inserting them diagonally into the connectors, could cause shortcircuiting and lead to breakdown of the electric elements on the boards.

C A U T I O N

 When reassembling the printer, make sure to route the FFCs

and other cables as specified in this chapter. Failure to do so may cause an unexpected contact of the cables with sharp metal edges, or lead to lower the noise immunity.

 When the printer has to be operated with the covers removed,

take extra care not to get your fingers or clothes caught in moving parts.

 When you have to remove any parts or components that are

provided as after-service-parts but are not described in this chapter, carefully observe how they are installed and make sure to remember it before removing them.

 The cutter blade is razor-sharp. Be especially careful when

handling the cutter.

 Carbide blade employed for the cutter blade is hard but brittle.

Be careful not to hit it against metal parts of the printer as it can be easily damaged.

 When you removed any parts (especially cables) that are

secured with acetate tape or two-sided tape, be sure to reinstall and secure them with the tape as exactly the same as they were.

 Disassembling the frame and some components of the printer is

prohibited because they are assembled with precise measurements in 1/100 mm unit at the factory.
