Epson® Stylus Pro 7900 & 9900 Instructions

How to install and use Piezography ink on the 7900 and 9900 printers.


Epson 7890 Printer

Use these procedures to convert your color printer to a Piezography printer.  If you are installing user refillable cartridges, please refer to the installation instructions in the "Support" menu above.

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 de-facto 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

This printer has been discontinued and unless you know intimately the condition of the printer you are going to convert, you should first verify that your printer functions perfectly with Epson inks or with PiezoFlush 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.

Flush cartridges.

Normally 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 (Light Grey Warm) is installed. Shade 5 which is 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 get rid of 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 spare maintenance tank (available through Epson) or a maintenance tank chip resetter *coming soon to a inkjetmall near you*

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.

Ink Change Procedure

Important Note: 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 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).

  • If you have a new printer, choose Ink Change Option A.

  • If you have an older printer that may have a head-failure due to excessive initial fills and you want to be more gentle with your printer, you can print out each channel using about 40-50 sq ft of cheap bond roll paper (per channel) and a special purge tif file downloadable below. choose Ink Change Option B. For more background information on Option B please read this.

Ink Change Option A:

  1. Test the printer with Epson inks, and have the necessary equipment on hand.

  2. Make sure you have a new maintenance tank in, otherwise this procedure won't work and will just fail silently without giving you a specific error message.

  3. Open the ink bays, and remove the remaining Epson cartridges from the printer.

  4. Install the flush or ink cartridges in the printer, and lower the ink levers.

  5. Turn the printer off.

  6. Hold the Menu/Right, Paper Feed/Down and OK buttons while turning the printer on. The printer will start in “Serviceman Mode”.

  7. Push the Menu button, scroll to and select CLEANING.

  8. Scroll and select INIT FILL.

  9. When finished, exit Serviceman Mode by turning the printer off, then back on regularly.
  10. If you have just installed Piezography ink, print a nozzle check pattern. If the ink channels are still stained with the original color inks, run a power cleaning on all channels.

  11. If you have just installed the flush cartridges, turn off the printer, allow it to sit overnight or longer (longer periods of time are not harmful to the printer), and then repeat the above steps to put the ink set in the printer. Allowing the printer to remain filled with flush fluid will help remove residue from the previous ink set.

  12. Important Note: Do not rely on the "automatic" nozzle check cycle on this printer. Always do you nozzle checks manually on gloss paper so you can also check the gloss channel nozzles.

Ink Change Option B: Purging the Ink from your printer through QTR and a special Purge Target:

  1. If you have an older printer that may have a head-failure due to excessive initial fills and you want to be more gentle with your printer, you can print out each channel using about 40-50 sq ft of cheap bond roll paper (per channel) and a special purge tif file downloadable below.

  2. Remove the Epson ink cartridges and replace with the Piezography filled SC-P cartridges. The cartridges must be filled according to the chart at the bottom of this document.

  3. Open QuadTone RIP Print Tool in Mac, or QTR in Windows. You will need to read the NEW Piezography manual to learn how to use QuadTone RIP (but, you need to do this anyways…)

  4. Set Page Setup for the printer and paper size you intend to use for purging.

  5. Open the X900-inkpurge.tif image (this image is a very specific RGB color and you should not modify it in any way nor allow its color management profiles to be applied, replaced, or adjusted. You can scale it larger as you need in QTR Print Tool or QTR

  6. Select Printer model and “No Color Management” (refer back to how to print with Print Tool), then click Print to send this purge file to QuadTone RIP.

  7. In the Print Window select the QuadTone RIP from the pull down list (layout).

  8. In the Mode pull down list, select QuadTone RIP Calibration (which will gray out the three curve pull down lists).

  9. Select 100% Calibration Ink Limit if printing on scrap heavyweight, coated/print paper or about 50-80% if printing on uncoated, very thin or typing paper.

  10. Select the paper feed: either sheet or roll 10. 1440dpi is fine to select for this purpose, bi-directional will print faster than uni-directional.

  11. Click Save.

  12. Click the Print button to print this purge page.

  13. Repeat 4-12 until you can see that the inks have been fully swapped out. It will be obvious.

Printer Specs & Review

Epson 7890 Printer

The 7900 and 9900 and SC-P printers have essentially the same ink-set as the 4900 printer with auto-switching black inks and 10 printable channels. This printer enables both Gloss and Matte K7 Piezography as well as our (2016 release) Piezography Pro Dual K5 MK/PK ink set. We still suggest getting an extended warranty 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 hereto 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 Editionset of curves and documentation. This will guide you through the process of installing your Piezography printer on both Windows and Mac operating systems so you can print.
