Piezography Ink Install Instructions for the Epson® Stylus Pro 7890 & 9890 Printers

How to install and use Piezography ink on the 7890 and 9890 printers.


Use these procedures to convert your color printer to a Piezography printer. If you are installing a Continuous Ink System (CIS), please refer to the installation instructions provided with the CIS. If you are installing user refillable cartridges, please refer to the installation instructions provided with the refillable cartridges. If you lost your refillable cartridge instructions, please go to our main support page to view the cartridge instructions. Whether you use refillable cartridges, CIS, or pre-filled cartridges (available outside the USA), the placement of the shades of Piezography ink are critical and not arbitrary. You must refer to the shade placement chart provided here on this document. Most Piezography systems depend upon the QuadtoneRIP software with which to control the ink shades. Installation instructions and support of that software is provided by the manufacturers of those software. We provide our own guides to our suggested use of QuadToneRIP, so that you can get the best results from that product. Additionally, Piezography on the Mac requires the use of Print-Tool. This software has quickly become a defacto utility for anyone wanting to properly color manage their printing workflow. A full manual for Piezography can be downloaded with the free Piezography Community Edition.

Printer Testing

Verify that your printer functions perfectly with Epson inks before installing Piezography inks. In addition to printing a perfect nozzle check, make certain that the printer does not have unfixable banding problems by making test prints. Take the time to scrutinize your printer’s performance before the next step. It is not possible to diagnose many printing problems on a printer that has not first been tested with Epson inks. Ideally you should also align your print-head for UniDirectional printing before switching to Piezography inks.

If you are having problems with your printer or print-head, please look at our detailed instructions on how to clean your print head.


Use of flush cartridges with the x890 and x900 printers

The use of flush cartridges is suggested and recommended when switching to Piezography inks from a non-Epson or non-Piezography ink set, or if you have been experiencing clogging problems with your current ink set. Otherwise, the actual Piezography inks can be used to "flush" out the pre-existing color inks from your printer. If you do not use flush carts, you may need to print some additional media before all traces of color ink have been removed. The yellow position is where the lightest shade 7 is installed. Shade 6 which is just marginally darker is installed in the light magenta position. On very old printers which will have deposits of color pigments in the dampers, a yellow and magenta cast in the highlights and 1/4 tones will be present for awhile without the use of flush carts. So weigh the costs of flushing with PiezoFlush (which will easily resolubize old pigments) or flushing with or printing out with Piezography ink to eliminate the initial color cast.

Items needed to have on hand when changing inks

A set of ink cartridges; a set of ink; a set of flush cartridges and flush fluid (if used); either ink or flush fluid for the Photo Black slot; a spare maintenance tank (available through Epson), or a waste tank chip resetter to reuse your waste tank.

Note about the maintenance tank: Instead of replacing a full maintenance tank, you may use a chip resetter to reset your maintenance tank chip to read empty, and reuse the tank many times. Follow instructions for reusing maintenance tanks, here: http://www.inkjetmall.com/tech/content.php?141-Reuse-Waste-Ink-Tanks

Changing inks in your printer.

Important Notes: In order to run an initial fill cycle, your new cartridges must each be at least 30% full. If they are less than 30% full, the printer will not allow you to continue until you replace those cartridges determined to be too empty to proceed. Once beginning an initial fill cycle, there is no way to abort it, and so your printer will be waiting for you to replace those cartridges it instructs you to install. If your Piezography and PiezoFlush cartridges are new, they will be full, but if they have been used in the past, removed, and you are now in the process of reinstalling them, you need to know how full they are before you go forward with the procedure. If you are not sure how full your Piezography cartridges are, install them and turn the printer on normally. The ink status monitor will display the ink levels. If they are not all at least 30% full, refill with ink and reset chips to read full (do NOT reset chips on carts that are less than full, because you can risk running the cart empty and getting air in your ink system).

Additionally, during this procedure, your maintenance tank may fill up, requiring you to replace it. If your maintenance tank is partially filled, it is a good idea to have a spare on hand. Maintenance tanks are available from Epson ink retailers, or you can follow our instructions for reusing them.

  1. Test your printer with Epson ink: print and evaluate nozzle check patterns and test images. Look for missing or misplaced lines in the nozzle check pattern, and examine your prints for potential banding problems, which will appear as unintended light or dark lines running through parts of your image. Fix any printer problems you may find, before you proceed to the next step. Note that if you have a brand new printer, you must install your Epson ink cartridges, in order to run these tests. Please follow the instructions in your printer manual for information on how to do this.
  2. Turn the printer off, remove the Epson ink cartridges and install the Piezography K7 ink and/or the PiezoFlush cartridges into the slots of the printer matching the color name on each cartridge. Close the cartridge bay doors.
  3. While the printer is OFF, press the EnterDown arrow and Right arrow buttons on the printer’s control panel. Turn the printer on and continue holding these buttons until the printer starts in "Self Testing" mode. Release the three buttons.
  4. Press the Down arrow button several times until the word "Cleaning" appears on the LCD screen on the printer. Press the Right arrow button to display "Std. CL1" shows on the screen. Press the Down arrow button until "Init Fill" (initial fill) is displayed. Press the Enter button as directed on the printer, to begin the initial fill process.
  5. Follow the instructions on the LCD screen to complete the Initial Fill cycle. After it completes, turn the printer off and back on, to exit the "Self Testing" mode.
  6. Print a nozzle check pattern, in "Manual" mode. (Do not use the automatic nozzle check pattern utility). A correctly printed nozzle check pattern will contain seven gray sections and one pink-colored section. The lightest shades of the K7 inks are very faint, and their nozzle check patterns may be difficult to see. However, if you can see them, then they are correct.

Epson 7890 Printer

Printer Specs & Review:

The 7890 and 9890 printers have the same inkset as the 3880 printers with auto-switching black inks and 8 printable channels. This printer enables both Gloss and Matte K7 Piezography as well as our (2016 release) Piezography Pro Dual K4 MK/PK inkset. The 7890 and 9890 are slightly newer than there build-cousins (the 7900 and 9900) and so have a little less head and maintenance issues than those other models. We still suggest getting an extended warrenty though, or plan on replacing the dampers and cleaning assembly at least every 2 years.

Piezography ink does much better than Epson ink in these printers due to having a smaller and more uniform nano-particle in the ink.

Storage of previously used ink cartridges

You may wish to remove and save one or more cartridges that you have removed from your printer, for use in the future. If you want to store your cartridges for later use, place the removed cartridges in plastic bags, close the bags tightly to minimize ink evaporation, and place the cartridges in a box so that they sit upright, as they do when they are in the printer. Storing a previously opened cartridge on its side or upside down will allow ink to leak out of the air vent holes. We recommend taping over the vent holes to prevent evaporation. Many of our ink cartridge (large and small) come with vent-hole plugs. Make sure to place these vent-hole plugs back into the cartridge before storage. Make sure to remember to remove them when you want to use the cartridge again though!

Note: On small format cartridges, it is very important that you do not allow ink to touch the air inlet filter. Make sure your cartridges remain upright at all times.


Getting started with Piezography printing and QuadtoneRIP.

Now that you have your inks installed, you must print your images through QuadToneRIP shareware software. It is not possible to achieve good results without using QuadToneRIP. Go here to download and install QuadtoneRIP for Mac or PC.

We provide a comprehensive user manual for Piezography along with a set of pre-made curves "profiles" for use with QuadtoneRIP and various fine-art inkjet papers. After installing QuadtoneRIP make sure to ask download and install our free Community Edition set of curves and documentation. This will guide you through the process of installing your Piezograhy printer on both Windows and Mac operating systems so you can print.

Supported Papers

We support an ever evolving list of fine art inkjet papers. You can see the list of officially supported papers here. Please note that this list is new as of 2016 and we have not yet updated every curve for every inkset and every printer and every paper (over 1500 different curves). This will take some time. Many curves work perfectly for a vast amount of differently branded papers. The Hahnemuhle Photo Rag curve (for example) will work just fine on Moab Entrada Rag. If you do not see your paper listed in the pre-made set of curves available from the Piezography Community Edition download, experiment by using a curve made for a similar paper.
