The Navigator DFE supports printers built on Memjet's DuraFlex platform. In this document we'll show you items specific to DuraFlex. On this site is a library of documents generally applicable to the DFE as well as documents specific to DuraFlex. You'll find both of them to be useful. They are organized in folders.
There are 4 basic applications that work together to drive a DuraFlex printer:
- Navigator Server
- Navigator DFE web client
- NCE (Navigator Configurations Editor)
- DuraFlex spooler
We'll talk about each of these in this document.

Version change information
The Server has 2 primary points of interest. The Workflow Action renderer settings and the Device Manager.
To access or change these settings, go to Manage Workflow actions > Render Action.
Navigator DFE contains the Harlequin Core scalable RIP. Depending on the number of RIP licenses you’ve purchased in conjunction with your hardware configuration it may be possible to enable additional RIPs for processing. Some printers may require additional RIPs to handle the data processing requirement. e.g. 2-wide or duplex.
Specific settings for this window are as follows:
- # RIPs per PC: This will correlate with the number of RIP licenses you have purchased. Enter the number of desired RIPs in this input field. Consult your support representative for help configuring the RIP instances correctly. A base system should have "1" under 'RIPs per PC'. So far, so good. If you want to have 3 RIPs working on your jobs simultaneously, enter 3. How this matches up to your RIP license in the LDK tool may be a little confusing if you don't understand the concept of the control RIP. An LDK license of 7 RIPs gives you 6 maximum for this dialog box. There is 1 RIP who controls the other RIPs in the Harlequin Core Scalable RIP. So if you want to have 6 RIPs working on your jobs simultaneously, you get a license for 7. 1 control RIP and 6 workers.
- # Threads per RIP: The number in this field should reflect the number of colors you are printing. This setting is per RIP instance. Ex: If you are printing CMYK, then you would want this value to be 4 regardless of the number of RIP instances. If you are printing a single color you would want to enter 1 in this field. Depending on your specific implementation this number may deviate from this general rule.
- Memory per RIP: This will be limited by the amount of RAM in your PC. Increasing this value may or may not affect the performance of your RIP.
If you followed along with our installation guide, or if someone installed your printer for you, this step is likely complete.
If you have not connected your DFE to your printer, then head to Device Manager.
To continue with connecting your printer to the DFE click here. If you've already done that, continue reading below....
There are a lot of controls and options hiding behind the "Advanced.." button. Likely this will be configured by Xitron or by your printer vendor. If you need help with the Advanced options, you might want to seek some advice from your technical contact at your vendor.
Let's go through them by number. The number in the picture corresponds to the number below.
1. Auto-start on Idle
The default state for this item is checked. Unless you have a good reason, leave it checked. It could just be called “Print the jobs”. Because turning it off stops you from printing anything until you turn it back on. If checked, the software will automatically start the print process when a job is submitted to the press.
If unchecked, the job will not be started and will sit on the press waiting to be printed. T It might become very important to you if you are trying to chain together very small jobs (e.g. multiple 1 page jobs that you want to print without gaps or without mid-job servicing) If so, look at this.
2. Auto clear fault.
The default state for this item is unchecked. If unchecked, the software will NOT attempt to automatically clear FAULTs on the press. Then you can see what is causing your faults because the error message will remain on screen and the printer will sit and wait for intervention.
If checked, the software will attempt to automatically clear the FAULT by re-initializing the press.
This flag controls whether the press will print data if media is present or not. It may be advisable NOT to print when there is no media under the print sensor. When this feature is enabled, the press will only print on the media and any excess image on the tail end of the sheet will be clipped so as to not cause ink to continue to be ejected once the media is no longer present. If this option is unchecked the tail end of the image can bleed off. Please note that extra image on the left or right of the media could still bleed as there are no sensors tracking media width. In the DFE it is possible to offset when the printing will start on the sheet to get a bleed on the lead edge of the sheet.
11. Y-resolution (DPI). (paper path direction) Choose each resolution, one at a time.
The DFE browser application has extensive documentation on this site.
However, there are a few DuraFlex specific items we will cover here.
Under the DuraFlex device dialog box....
To get to the printer management page, click the settings button from the DFE main page.
That will bring you to the Duraflex engine controls.
You will see Printer Status on the left. The second column has global print settings that effect every print job.
There are test prints you can send to the printer and maintenance you can perform on the printer.
We'll go over these in detail below.
When you first open the Duraflex engine controls window it will look like this:
However, Duplex and Stitched-wide systems will look different.
Pause after every job will cause the RIP to pause after the last page of every job and require the user to release the next job with a manual click on the main page of the DFE.
This may be useful if your workflow requires frequent paper changes.
Mid Job Servicing turns on or off the Duraflex mid job servicing feature. Please see your printer manual for more detail.
Test Prints Printer manufacturers may add jobs they wish to create as a test print (for quality or positioning tests for example) via the Navigator Server "Import Files" menu.
Printhead Cleaning. You can choose from three levels of printhead cleaning here. They take increasing levels of ink and time. Start with Light if you are not sure what to do.
There are several advanced engine controls hidden behind a lock with a password. This is to prevent inadvertent clicking of maintenance functions that may take considerable time.
To unlock these functions, click the lock as seen below.
UPDATE JULY 2022:
New feature added to support plastic "system bring-up" fake printheads. This dialog now looks like this:
Details on the "bring-up" plastic printheads follows below.
A password dialog will come up.
Consult your printer supplier for this password. The default password in our development builds is "xitron". Your printer manufacturer may have their own password. Once the password is accepted you will see the screen below.
The functions may be self - explanatory but please consult your printer manual for more detail on what to expect from these functions.
Currently, these functions are:
Circulate Ink (used during initial system installation if using plastic printheads)
Drain Ink (used during initial system installation if using plastic printheads)
1. Top of Form Adjustment: This input field is for entering an additional TOF adjustment on top of the position that exists in the Advanced Device Settings within the Navigator Server application. This will assist in offsetting the content of a job toward or away from the TOF sensor when setting up bleed jobs or in other special circumstances.
Note and/or warning:
If you are making changes to the hydration settings when a value already exists in this input field, please double-check your positioning once you have the desired hydration settings in place. You may end up with declog or spit bars on your printed piece.
2. Top of form adjustment: For duplex units, this adjustment is for the second printhead(s).
The Job Editor window has a a few significant changes.
The pulldowns for items 1, 2 and 3 of this list are bound to the Quality pulldown to get default settings. The Quality pulldown is essentially the Render Config list from within the NCE. The following items can be overridden from what exists in the Quality/Render Config pulldown:
- Paper: This is the list of available ICC profiles that are available in your system.
- Calibration: This will override the default calibration selected in the Quality/Render Config pulldown.
*Note: If a render config and calibration have the exact same name, that calibration will override any item selected in this pulldown.
- Tone Curve: This pulldown contains the list of available tone curves that are defined in the NCE.
- DuraFlex button: This is for entering the speed of the media transport on your unit. A more detailed description is located below..
DuraFlex speed controls.
- Maximum Speed, checked: This is default. This will use the setting from Navigator Server for your chosen resolution.
- Maximum Speed, unchecked. Enter the speed for the media transport system, on a per job basis, in the field here.
Navigator Configurations Editor
The spooler is occasionally useful if you want to see more information about what the job is doing, what the data rate between the DFE and printer is, or if you want to look at the logs.
You can also set the spooler buffer and do other configuration from behind the Configure button.
