PM-417D and PM-417P Installation Guide
This website will provide software and information on setting up a Postmark PM-417D or PM-417P print engine.
The encoder provides the speed of the transport belt to the printer to ensure accurate registration and stitching. The PM-417 requires a 300PPI input. All postmark provided encoders use an 1800 pulse per revolution encoder with a 6" circumference wheel (Figure 1). The input connector for the encoder is an M12 Circular connector (Figure 2). After securely mounting the encoder using the included instructions, connect the M12 cable from the encoder to the back side of the Ink Tank Assembly Box (Figure 3).
Photo Sensor (TOF - Top of Form Sensor)
The Photo Sensor (also referred to as TOF sensor) identifies the leading edge of the substrate being printed on. Different substrates and transport assemblies may require different types of TOF sensors. The postmark provided sensor is a contrast sensor which can be used with a retroreflective target or on a solid belt (Figure 4). The input connector on the Ink Tank Assembly Box for the sensor is a 4pin M8 circular connector. This connection is common for most industrial sensors.
The included mounting hardware for the sensor can be used for standard 22mm sensor mounts as well as a variety of fiber optic cable sensors for specific applications.
To install the sensor, loosen the orange handle and slide the sensor mount onto the 12mm shaft (Figure 5).
Center the sensor where media will be fed and lock the sensor in position (Figure 6).
After the sensor has been mounted, connect the M8 connector from the sensor's yellow cord (Figure 7) to the back of the ink tank box next to the encoder input (Figure 8).
Waste Lines and Maintenance Cartridge
The PM-417 requires an exit path for any waste ink which is used for cleaning and draining the printhead (Figure 9).
The default configuration for the PM-417 is to use the included maintenance cartridge box (Figure 10) and a disposable maintenance cartridge to collect the waste ink (Figure 11).
The maintenance cartridge box connects to the back of the ink tank assembly using a length of 2mm ID tubing and an M8 male to female cordset (Figure 12).
Waste ink can also be diverted to a different receptacle if requested although it requires some software adjustments. By default, the system will generate an error code if the maintenance cartridge is not installed or the calculated waste ink levels indicate that the maintenance cartridge should be replaced.
The Maintenance cartridge box location is not critical. There are two threaded M4x0.7 Mounting holes on each side of the maintenance cartridge box for mounting or it can be placed on a table top for some applications (Figure 13). There are two mounting holes included in the backing plate on the PM-417 where the box can mount under the ink tanks of the printer (Figure 14). The default configuration can be seen in Figure 15.
In order for a computer to communicate with the PM-417, a USB and a serial RS-232 connection are required. Postmark includes a 6ft USB A to B Cable which installs on the back side of the Ink Tank Assembly Box near the encoder and photocell input.
USB is the main connection that drives the printhead. All print data, service instructions, and settings are sent via USB. The USB connection port is shown in Figure 16.
The maintenance utility will only communicate over USB.
RS-232 provides the necessary "start print" and "stop print" commands required by the printhead to print. These communications are handled either by the Xitron software or by an external controller. Without the RS-232 communication, the printer will never start printing although it may show the status as "printing".
Postmark includes a USB to RS-232 adapter (Figure 17) which allows this communication to be sent via an emulated serial port in windows.
Drivers for the USB to Serial converter can be downloaded here:
Starting the printer for the first time
Once all the connections have been made it is time to install the ink cartridges and turn on the system. If using a maintenance cartridge, be sure that it is installed in the maintenance cartridge box.
Install the ink cartridges in their corresponding ink tank holder and close the blue latches (Figure 18).
The printer should start loading ink automatically as long as everything is connected correctly and there are no errors. It is recommended to watch the printer status during this process by opening the maintenance utility.
Using the Maintenance Utility
Download the maintenance utility .zip file from the link below and extract the contents to a known location:
A 64 bit operating system is recommended for most applications including use of the Maestro / Xitron software. The 64 bit version of the maintenance utility can be found in the 64 bit folder included in the above link.
The maintenance utility is a self sufficient program and does not require an installer. You will just need to open the correct version based on your operating system.
With the printer turned on and connected, run the maintenance utility 4PM_MaintenceUtilityEn.exe
A window will come up prompting a mode to be selected (Figure 19).
For most applications, key operator mode is sufficient.
For advanced servicing and troubleshooting, Administrator Mode can be used by inputting the password: printmodule
For the initial setup run the maintenance utility in key operator mode.
Next a window will come up asking which connection the printer is using (Figure 20), in most cases this will be via USB. The maintenance utility can be ran in offline mode for training or remote servicing aid.
The maintenance utility will now be ready to use given the printer is working correctly. The following manual can be referenced for details on the functionality of the maintenance utility:
As the printer is loading ink, press the printer status button in the maintenance utility to monitor the status (Figure 21).
The ink loading process usually takes about 30 minutes. If any error codes arise during this process consult the service manual for more details. If ink does not start loading it is possible there is an error preventing the printer from starting, which will be shown in the printer status window. Again, consult the service manual if this happens.
Once the ink has finished loading the status of the printer should show online / ready (Figure 22):
At this point setup has been completed and you are ready to install the xitron software as explained here:
Please note that a sample print from the Xitron software must be made before you are able to print test patterns and calibrations from the maintenance utility, doing so initializes the RS-232 serial communication. The Xitron software handles the RS-232 communication and must be open (unless you are using an external controller).
