What Is New About the 7600/9600
CSIC Ink Cartridges
CSIC (Customer Satisfaction Ink Cartridge) chips on the Ink Cartridges, inform the Printer about:
• The type of ink (dye or pigment).
• The color of the ink.
• The quantity of the ink.
• The vendor, date manufactured, etc.
7 Nozzle Sets, Pigment or Dye
The 7600/9600 are equipped to handle either pigment or dye ink from the factory. The User has three ink combinations to choose from (all combinations include cyan, light cyan, magenta, light magenta, and yellow).
• 7 color pigment (black and light black)
• 7 color pigment (matte black and light black)
• 6 color pigment (two matte blacks)
• 6 color dye (2 photo blacks)
If the User installs eith er of t he pig ment ink se ts, the Printer recognizes the ink and becomes a pigmen t Printer. The
customer can switch from one pigment set to t he o ther, but never to dye. If the User installs dye inks f irst, the Printer
will not accept pigment inks (and vice versa).
4 Platen gaps
The Printer has a Paper Thickness Sensor like the other Epson Large Format Printers. This sensor r ecognizes
two thickness of paper, and sets the platen gap accordingly ( Standard or Wide). There are two additional gaps (Nar-
row and Wider). These gaps must be set through the Driver, or SelecType.
User Waste Ink Tank Replacement
The Waste Ink Cartridge is designed for the User to remove. It has a CSIC like chip attached to it, and is easily slid
out of the right side of the printer. The quantity of ink contained by the Waste Ink Cartridge is stored on the CSIC
What Is New About the 7600/9600 Printer Component, Software Item, LCD Display, Printer Button Page 7.
Stylus Pro 7600/9600 Field Repair Guide 7/22/02
chip. Consequently, a new cartridge will also reset the Cartridge Counter.
Easy Removal of the Cap and Pump
After the Right Side Cover has been removed, only 4 more screws must be removed to remove th e Cap and Pump
Assembly. All 4 screws are removed from the back side of the Printer.
One Print Head
7 nozzle sets, on a one piece Print Head. One Print Head mechanical adjustment (head rotation).
Back Light on LCD
The back lit LCD is easy to read.
Auto Open Valves in the Ink Bays
Inserting an Ink Cartridge opens a spring loaded Valve located on the inside of each Ink Bay.
No Front Paper Sensor
The Front Paper Sensor has been eliminated. The Paper Edge Sensor is used for Leading Edge detection.
Electronic Paper Sensor Adjustments
The Rear Paper Sensor and the Edge Sensor adjustments are performed from the Self Diagnostic/ Check:Adjust
menu. The Printer senses the paper and writes the appropriate level to the Main Board. On earlier Epson Large
Format Printers, a potentiometer was used to set the level.
Edge to Edge Printing
The 7 600/9600 Printers can print with no top, bottom, or side margins. All margin adjustments are cri tical for this type
of printing. The printer also has many foam screened openings in the Platen area to catch over spray.

Epson User Print Quality Solutions
The Stylus Pro 7600/9600 provide the Print er User with three methods for tuning their Printer to their job specifications, media, and ink.
The print quality solutions discussed in this document are the responsibility of the User and the Epson
User Phone Support Group to implement. The purpose of this document is to inform the Service
Technician of the User solutions, only.
The three methods for tuning the User’s Printer fall into two groups.
• Methods that work with the Epson Printer Driver.
• Methods that work with Non-Epson Printer Drivers and RIPs.
Epson Printer Driver Support
Epson Printer Servic e Utilit y
This utility allows the User to control:
• Ink drying time between passes (to reduce smearing).
• Paper feed pitch (to reduce horizontal banding).
• Suction Fan power (to reduce vertical rippling on thin media).
• Cut Method (to reduce cutting errors on thin media).
• Ink density (to increase or reduce saturation).
• Turn off MicroWeave (to increase speed, but cause horizontal banding).
• Update Firmware.
• Perform Bi-Directional and Head Gap Adjustments.
• Perform a strong Print Head Cleaning
The Epson Printer Service Utility consists of menu choices and test prints that allow the User to adjust the custom
settings. The adjusted custom settings are named and saved. They can be loaded from the Custom menu on the
Printer Driver at the User’s discretion.
A Technician should use his media, image, and driver (computer) to bypass all User settings.If the
Epson User Print Quality Solutions Printer Component, Software Item, LCD Display, Printer Button Page 48.
Stylus Pro 7600/9600 Field Repair Guide 7/22/02
Printer is aligned properly, and works with the Technician’s media, image, and Prin ter Driver, the issue
should be referred back to Epson Phone Support.
Epson Printer Driver (Paper Config Section)
This Section of the Printer Driver does essentially what the Epson Printer Service Utility does. It can be used to adjust
and save custom settings. They can be loaded from the Custom menu on the Printer Driver at the User’s discretion.
This method has no test print support, and requires more experimentation and User knowledge.
Non-Epson Drivers/RIPs Support
The Stylus Pro 7600/9600 Printers utilize numerous media and ink control featur es that are accessed by
commands built into the Epson Printer Driver. The purpose of the control features is to improve print
quality and minimize banding, and saturation issues. Non-Epson Drivers and RIPS do not support
those control features.
The SelecType / Paper Config menu allows the User to configure the Print er to use a group of custom settings on
every job that is received that does not contain Epson Printer control featu re commands. The following i s a list of custom settings supported.
• Paper Number (to assign a number to the custom settings).
• Cut Pressure (to control cutter blade pressure).
• Cut Method (to reduce cutting errors on thin media).
• Paper feed pitch (to reduce horizontal banding).
• Drying time (to increase Ink drying time between passes to reduce smearing).
• Suction Fan power (to reduce vertical rippling on thin media).

Ink Cartridge Errors
APS FYI Bulletin 07/18/02
1. Question:
I just purchased an UltraChrome Stylus Pro 7600/9600 printer and intend to use it with Matte Black ink only. Could I
initialize and perform initial ink charge of the printer with Matte Black ink?
1. Answer:
No, you will not be able to initialize the print er and perform initial ink charge with Matte Black inks. You must first initialize the printer with the UltraChrome Black/LBlack ink that was shipped with the printer. Once the printer has been
initialized, then perform the ink swit ch as described in the SP 7600/9600 User's Guide under Switching Between
Black Ink Modes section. This switching process will take about 10 minutes and it will take of up to 180 - 215 ml of
ink total across all 7 ink cartridges.
2. Question:
I have already installed the Matte Black inks into my Stylus Pro 7600/9600 printer as part of the initial charge cycle
and now I am getting "Wrong Cartridge” error and the printer will not initialize even after placing the UltraChrom
Black/LBlack inks into the printer. What is wrong and how should I recover from this?
2. Answer:
You must remove the Matte Black ink and initialize the printer using the UltraChrome Black/LBlack ink that shipped
with the printer. If this does not work contact technical support for assistance. If the ink initialization flag data is corrupted the printer may not be able to recognize the UltraChrom Black/LBlack ink cartridg es and it may be required to
change the NPD value under Maintenance Mode 2* to “0” to get the printer to initialize. Make sure the customer has
the UltraChrom inks installed then switch the NPD value to “0”.
1. Power Off the printer. Press Paper Source + Paper Feed - (down) + Cut/Eject buttons then power On the printer.
2. Navigate to Service Config mode then change the NPD value to “0”.

Glossary
Artifact A defect, that is within an image. It can mean something on the gr aphic that was not
intended, or something missing that was intended. All image quality defects are artifacts.
Bi-Directional Adjustment: An electronic adjustment, that ensures that a printer can coordinate left to right , with
right to left, printing.
Capped Position: The print head at it’s stand by position, with the cap mechanism sealing the nozzles. Coating: The top layer of graphics paper (media) that consists of a special substance
designed to trap ink and keep it from being absorbed into the paper fibers. Non-pap er
based ink jet media uses coating to allow the ink to bond with the surface. A coatings
purpose is to minimize dot gain, and control saturation.
Color Shift: An unintended change of a gradient or tone.
Continuous Tone: The qualities of a photograph that makes an image appear real. The smoo th and li fe-
like transition from one color shade to the next , like in a photograph. Epson Ink Jet
printers are not continuous tone printers. But when working properly, their printed
images fool the human eye into seeing continuous tone transitions.
Debris: A term that refers to unintended ink on the page deposited by debris dropping from
the print head.
Deflected Nozzle: A nozzle is firing, but the ink drop is not landing where it is intended too. Irregular
spacing on the nozzle check pattern indicates this condition.
Dithering: The dot pattern placed on the printed surface to create and image. Also known as
screening.
Dot Gain: A drop of ink tends to travel out from it s point of impact, as the media absorbs it . The
purpose of the coating (on the media) is to minimize dot gain.
Glossary Printer Component, Software Item, LCD Display, Printer Button Page 55.
Stylus Pro 7600/9600 Field Repair Guide 7/22/02
Drop of Ink: Ink that appears to have dripped from the print head, or any other component of the
ink supply.
Dye Ink: Ink that colors the printed surface with dye. It is less durable than pigment ink, but
has a wider color range (gamut).
Electronic Alignments: Printer adjustments, which are performed using soft wa re routines that, allow the
printer to compensate for physical variations in its mechanism.
Error Diffusion: The type of dithering (screening) proprietary to Epson, that empl oys a random dot
pattern to ensure that the human eye can discern no pattern.
Flight Time: The time it takes a drop of ink to travel from the print head to the printable surface.
Gamut: The range of colors that a printer can produce.
Ghosting: A term that refers to components of an image that are intende d to be on top of each
other (or adjacent), but are offset.
Gradient: A smooth transition between one col or shade, and the next. A co ntinuous tone image
requires a smooth gradient for all its tonal shifts.
Grainy: A breakdown of the “illusion of continuous tone”. A printed image that does not have
smooth tonal transition, and sharp detail.
Head Angular Adjustment:
Glossary Printer Component, Software Item, LCD Display, Printer Button Page 56.
A term that refers to a mechanical print head alignment that ensures that an ink jet’s print heads
nozzles are on the same vertical plane. (Also known as the B head slant or the C head slant.) The
head is rotated until it is vertically linear.
Stylus Pro 7600/9600 Field Repair Guide 7/22/02
Head Gap Adjustment:
An electronic print hea d adjustmen t that ensures tha t the printer knows the exact dis tance betw een
nozzle sets on separate heads.
Head ID: The calibration value written on the print head that allows the printers electronics to
compensate for the print heads “personality” (inaccuracies).
Head Linear Adjustment:
A mechanical print head alignment that ensures that on a two-head ink jet printer that all the noz-
zles are on the same hor i zon tal plane. (Also known as H e ad Height and BC Head Sl a nt.) The r ig ht
head is moved in relation to the left head.
Home Position: The print head’s horizontal reference position, as determined by the Home Position
Sensor
Horizontal Banding: An image defect that extends from the left, to the right margin (parallel to the direc-
tion of print head movement). The defect could be a lighte r or darker “band” than is
intended. It usually repeats, with the same interval, from the top margin to the bot-
tom.).
Horizontal Over-lap: A type of horizontal banding, whe re multiple print h ead passes overlap while printing.
The banding looks darker than the intended image. Multiple passes of the print hea d
should place ink on the paper next to, but not on top of earlier passes.
Glossary Printer Component, Software Item, LCD Display, Printer Button Page 57.
Stylus Pro 7600/9600 Field Repair Guide 7/22/02
Horizontal Under-lap: A type of horizontal banding, where multiple print head passes have a space
between them. The banding looks lighter than the intended image. Multiple passes of
the print head should place ink on the paper exactly next to earlier passes with no
space in between.
Illusion of Continuous Tone. A term that refers to “fooling” the human eye into perceiving a dot matrix image as a
photograph (continuous tone image). Epson ink jet printers are not continuous tone
printers. However, when working properly, their printed images fool the human eye
into seeing continuous tone transitions
Ink Color Contamination: The intended color of the ink supply has been altered.
Ink Impurities: Foreign objects in the ink supply.
Margin Shift: A term that refers to an image with irregular right and left side margins.
Mechanical Alignments: Printer adjustments, that requires physically moving parts of the mechanism.
Media: The surface that is being printed on, usually paper.
Metamerism: The different appearance of colors caused by different light sources and viewing
angles
Micro Weave: The way an Epson Ink Jet printer interlaces (weaves) bands of and image during
printing.
Moiré Pattern: A repetitive pattern, within an image, which is not intende d. I can appear like a pais-
ley or herringbone pattern.
Over Saturation: Too much ink has been applied to the printable surface for the media to support.
Paint Brush Effect: Something horizontally across the printed surf ace, that was not intended. Usually
caused by an ink soaked fiber hanging off the print head.
Pigment Ink: Ink that deposits colored particles (pigment) on the printed surface to create an
image. It is more durable than dye based ink, but does not have as wide a color
range (gamut).
Glossary Printer Component, Software Item, LCD Display, Printer Button Page 58.
Stylus Pro 7600/9600 Field Repair Guide 7/22/02
Pixilated: An image quality issue that is caused by a low-resolution image printed at high reso-
lution.
Platen Gap: The distance between the print head, and the printable surf ace.
Rippling: A term that refers to a condition caused by over saturated paper warping.
Saturation: The amount of ink applied to the printed surface.
Screening: The dot pattern placed on the printed surface to create and image. Also known as
dithering.
Skew: Crooked paper in the printer.
Smear: An image that has been rubbed by something, causing it to be deformed, or
smeared. The direction or any repetition of the smear should be noted.
Smudge: Something on the printed surface, that was not intended. Usually transferred to the
page because of contact with a dirt y roller o r the print head. Any re peti tion should be
noted and measured.
Sublimation Ink: Ink that is first printed on thermal transfer media, and then transfer red using heat to
another surface.
Sympathetic Nozzle: A nozzle that is not intended to fire, firing in conjunction with an intended nozzle.
Tone: The specific shade of a color.
Under Saturation: Not enough ink has been applied to the printable surface to properly saturate the
media.
UN-sharp: “Fuzzy “qualities in an image usually caused by too much dot gain.
Vertical Banding, Irregular: Vertical bands perpendicular to the direct ion of print head movement, that are not lin-
ear. Usually created by paper “rippling”, caused by over saturation.

V ertical Banding, Linear: An image defect that extends from the top, to the bottom margin (perpendicu lar to the
direction of print head movement). It usually repeats, with the same interval, from the
left margin to t h e ri gh t.
White Specks: A term that indicates that the intended image has small missing areas where no ink
has been deposited.
