WARNING: The Sellenis S-Jet 600 printers are built, assembled and tested to Sellenis’ standard of

quality and specification to ensure reliable, trouble free operation of the printers. The Printer

controller and associated printhead must not be dissembled, opened, altered or tempered with to

ensure guaranteed functionality and performance as specified. Please use the Sellenis S-jet600

series as per Sellenis’ specification, instructions and information.

If a S-Jet 600 problem is suspected, the user should first attempt to correct or verify the problem,

following the Troubleshooting Guide of this document, before contacting Sellenis’ Help Desk.

Furthermore, when it becomes necessary to contact the Help Desk, the user may greatly speed up

problem resolution by providing detailed information such as:

Software version

Printer configuration (one head? Two head etc…?)

Printing mode (standard, repeat, simulated etc…)

Template being printed

Pen to product distance

Etc…

after starting

/running printer

software

Most likely cause is

printer IP is not set

Software needs

restarting

Least likely cause is

that Ethernet cable

inside controller not

connect to the main

Sellenis board

Set printer IP as per the sellenis note entitled

“connecting to printer & firmware version display

Ver 4” – see appendix 1

Exit Sellenis software wait 30 secs to 1 minute then

re-launch the software again

If the controller has been opened and before it was

opened it was ok, then open the controller and

check all cables have been recconnected to their

respective corret positions (see appendix

Printing Process

Condition

Probable cause

Correction

Not printing on

products in

standard printing

mode

“ SENC direction “

setting is incorrect

“group 1” distance

setting incorrect

Nozzles blocked

Photocell not adjusted

Shaft encoder wheel

not rotating and not in

contactwith conveyor

Inaccurate print speed

setting when running

on internal shaft

encoder

Ensure standard mode printing is checked

Ensure photocell is connected to controller

Ensure photocell sensititivity is adjusted correctly

Ensure “SENC Direction” in configuration screen is

set correctly (AB if shaft encoder wheel is rotating

clockwise and BA if it is rotating anticlockwise)

Measure distance from photocell to printhead and

enter the value in “Group 1” space

Check that cartridge nozzles are not blocked clean

nozzle face accordingly

Ensure shaft encode wheel is rotating or that

internal shaft encoder is set

Not printing on

products in repeat

printing mode

Same as above

Repeat spacing on

product in repeat

printing mode

appears to be

bigger than

expected

“Repeat spacing” set

incorrectly

From version V4402 onwards “Repeat spacing” is the

distance from end of a template (not end of the image)

to the start of the next template (not the start of next

image). Therefore if it is desired to have a narrow

repeat spacing between repeat images do not create a

template with empty space at the start or end of a

template.

Note: Repeat printing mode MUST be implemented

with real shaft encoder and real photocell ..it does run

with internal shaft encoder or internal photocell

“Printing too fast”

error

The print speed set in the

simulated printing mode is

set high

Set print speed so that the number of “PD count” is

approximately equal to number of “Images” shown

on the print screen statistics table.

Review maximum print speed specification related

to print resolution

Printing stops

automatically and

print stop red icon

comes on.

Cartridge empty of ink

Cartridge unrecognised

Check ink level in ink info screen

Replace cartridge

Controller

suddendly cannot

read one or more

cartridges

If not above causes then

possible electrical

interference

restart printer. Switch power off …wait 1 or 2

minutes then switch power back on. Restart printer

software.

Ensure adequate earthing of system as well as

conveyor.

Print Process

Condition

Probable cause

Correction

It is possible that the below two errors can occur if either the controller or the printhead has been opened and then

either the main board has been damaged or the printhead flexible circuit has been cut during disassembly or re-

assembluy into the printhead. Please do not open controller or printhead to avoid the risk of damaging these two

components and voiding the warranty.

No printing from a

pen and in the

print statistics

screen the ASIC of

that pen displays

255 number

Printhead not

connected to controller

and therefore

controller is unable to

communicate with

printhead

Faulty main board

Check printhead is connected to controller.

Try connecting the printhead to another controller.

If it works ok when connected to another controller

then it is likely the a printhead channel in the main

board has failed. Return board to sellenis

No printing from a

pen and in the

WARNING: The Sellenis S-Jet 600 series are Windows touch screen based printer systems. The S-

Jet 600 priner controller MUST be used as a printer controller and no more. It must not be used as a

personnel PC for surfing the internet and/or downloading other software applications. It is

recommended that the printer controller not be connected to the internet if not necessary for its

functionality unless it is using nicelabel or external protocol.

The below issues will only occur if the user has opened, replaced some parts and altered the S-Jet

600 printer controller buid and assembly specification. For example:

if the printer controller has been openened and one of the USB hub in the controller has

been removed and replaced

if one or more of the cables have been disconnected and reconnected to different ports of

the USB hubs inside the controller

if one or more of the cables have been disconnect and not reconnected again to the

appropriate port/connection.

If any of the printer settings in Windows has been atered or if the user has been using the

printer controller as a pc surfing the web and/or installing other applications.

Connection to Printer & Display of Firmware version

Page 9of 24

Connection to Printer & Display of Firmware version

Connection to the printer and display of Firmware version in pre-programmed boards (Software

version V4xxx) can take up to 15 seconds.

The following are description of steps to take to diagnose and try to resolve possible issues that

might prevent the software from connecting to the printer and therefore not displaying the

firmware version on the start up screen.

If the firmware version fails to display, please restart the software again and wait for up to

30 seconds and only then if connection was not established should you investigate

further?

The software writes all errors to the Log file. Looking at this log file can reveal why the software

has not connected to the printer and why it has not displayed the firmware version. To open the

software log file, the user needs to sign in to the software and open the log window (picture 1) by

clicking on the icon shown in picture 1.

Picture 1

The screen as shown in picture 2 is displayed. Scroll down to the latest date and time and click

on the correct last time of the last date to open the last event log.

Picture 2

Log window

Page 10 of 24

If the log contains errors, these will be shown in red text and can explain why the printer was not

connecting. Below are explanations of all possible error lines associated with the software not

being able to connect to the printer:

1. "Failed to open port, code: XXX”- FTDI chip issue. It might be because windows has

locked the micro USB driver on the main board. Solution - restart Windows and then

restart the printer software.

2. "Failed to connect to send socket.”- This means that we need to set the printer IP as it

appears not to be set. Solution - check if IP is set to 192.168.100.200. Go to Windows

and open Control Panel. Thereafter:

a. open “Network and Internet”

b. Open “Network and sharing centre”

c. Click on “change adapter settings” (on the left side of screen)

d. Right click on one of the “ASIX AX88179 USB 3.0 to Gigabit Ethernet Adapter #/“

e. Click on “properties”

f. Select “Internet Protocol Version 4 (TCP/IPv4)

g. Click on “properties”

h. Select “use the following IP address”

i. On the top box enter the following printer IP address 192.168.100.200 then enter

on the box below this the subnet address 255.255.255.0 then press ok

j. Now go back and open the printer software.

Important note

If another main USB hub was connected to the controller and was replaced by a new new main

USB hub, then in this case, Windows might not allow you to set the printer IP address as

described above. If when trying to set the printer IP address as above, a message is displayed

as below

---------------------------

“Microsoft TCP/IP

---------------------------

The IP address 192.168.100.200 that you have entered for this network adapter is already

assigned to another adapter 'ASIX AX88179 USB 3.0 to Gigabit Ethernet Adapter #4' or 'XXXX

USB 3.0 to Gigabit Ethernet Adapter #4 on this computer. If the same address is assigned to

both adapters and they both become active, only one of them will use this address. This may

result in incorrect system configuration.

Do you want to fix the problem by entering a different IP address for this adapter in the list of IP

addresses in the advanced dialogue box?
