1.0: SAFETY PRECAUTIONS
CAUTION
The equipment described in this manual does not represent high risk of danger. However, it
is installed on a machine that can be dangerous:
 The equipment described in this manual is covered with fix panel (only opened with a tool) that
provide protection from electrical components and most of mechanical motions. However,
there is four (4) belts that can be exposed to the user. ALWAYS turn OFF the machine before
approaching hands from every motion part to remove a jam, service or clean the machine. Go
against this notice can result in a severe injury or death.
 The equipment described in this manual is designed and manufactured to the highest KLR
standards. Special attention made to ensure that the operation of the machine is safe and
convenient without compromising the efficiency. Keeps hands away from the working area of
the machine.
 Keep hands away from the working machine. Do not force through gaps or from the top.
 If the system is linked to another machine or install onto another machine. Lock the electrical
box of the other machines before performing any maintenance on this equipment. Please refer
to the local regulations and laws on locking out machinery. Go against this notice can result in
a severe injury or death.
 When working on the electrical components. Disconnect the equipment at the source and use
a lockout device to avoid any risk of danger. Make sure you also have the space required to
complete the work to avoid any risk of danger.
 Any modifications with any aspect of the mechanical, safety, electrical design, design, or any
parts connected with the equipment will void the warranty and liability of KLR Systems. If a
change is required, contact KLR Systems for approval. All technical handling must be done by a
qualified technician or by KLR Systems.
 KLR is not responsible for any abuse, mishandling, misuse, improper maintenance and repair
by owners and users.
 Equipment must be supervised when operating.

CAUTION
 Safety switches: DO NOT bypass any safety components for any reason. Violation will void all
warranties and responsibility from KLR Systems. If a safety component is broken, it must be
replaced before starting the machine.
 Safety panel (fix panel) or safety doors: As a safety, component does not try to remove or
unscrew them unless it is necessary for a maintenance operation. If it is the only option, use a
lockout device during this procedure and reassemble every single piece as it was when finished.
 When the machine is set to interlock mod, that means the KLR.950 run command and speed is
controlled by another equipment. Careful when handling the equipment because it may start
when you do not expect it. ALWAYS keep hand away from belts and mechanisms even when
the machine is stopped.

3.0: PRODUCT SPECIFICATION
3.1: Range of applications intended use and general functions
Used to print on clip, the inkjet printer KLR.937 is designed to be installed on the bag closer KLR.950. The
printer uses the interface of the KLR.950 to create convenient layout. These following values are in the
prototype version and are subject to change:
 Speed in excess of 60 packages a minute.
 Uses the convenient touch screen (HMI) of the bag closing machine.
 Uses an easy display to create many different layouts, can be fine tuned according to the user’s
needs.
 Made of stainless steel and anodize aluminum.
 Print automatically when loading the clips in the KLR.950 (if set in the parameters).
3.2: Dimensions (for transport)
Note: some parts are not assembled when the printer is sent alone.
Height: 5 inches
Length: 9.5 inches
Width: 5 inches
3.3: Specification for electricity
WARNING
 Using another cable then the one provided by KLR can
damage the equipment and void warranty.
This machine is intended to be connected to the bag closing machine:
Electrical need: 28 Volts DC from the KLR.950 bag closer.
Provided in the packaging with the machine:
PE-95003-1
In case of loss, order from KLR to get a new one and be sure to have the cord as per requirement for
your machine.

4.0: INSTALLATION
4.1: DC Power supply
CAUTION
 Electrification or electrocution hazard, only qualified
technician can perform these tasks.
When installing a KLR.937 ink jet printer, changing the power supply, or to troubleshoot a not
functioning ink jet printer. The power supply must be set to 28 volts rather than 24 volts. Follow these
instructions to set it properly:
Note: From KLR, the power supply setting will always be 28 volts regardless of what options on the
machine. But in fact, only the machine that uses an ink jet printer must be adjusted to 28 volts
1. Remove the back panel of the bag closing machine.
2. Turn ON the machine.
3. With a multimeter set to DC mod, probe the + and – from the output and use a terminal
screwdriver on the ADJUST screw.
4. Adjust the voltage until you reach 28 volts.

5.0: BASIC SETUP AND OPERATION
 Before using the machine, it is important that every operator of the machine and
maintenance personnel take part in a training session given by KLR systems
technicians.
This part of the manual is for the user that want to do daily tasks or small modifications to a machine
that has already been configured by KLR as per requirements. Every KLR.937 ink jet is set in factory as
per the costumer’s needs prior to delivery. For complete setup, from a blank layout to a fully functional
print, see Unlock advanced parameters and Advanced printing configuration.
5.1: Ink jet printer configuration
Note:
This section is only for the machine that has the
KLR.937
"
ink jet printer
"
option. Moreover,
"
air
printer" is another option available on this equipment. To have more information regarding to air
printer, see KLR.930 manual.
Press PRINT CONFIGURATION button.
5.1.2: Changing date and text on clips
Note:
Make changes in the printer configuration such as date is saved automatically in the system.
However, it can take between 2 to 5 clips before the changes really happen. Always make sure the
changes are as intended looking at the result on the fifth clip.
5.1.2.1: Basic ink jet configurations
Some parameters are locked to simplify for configuration that changes rarely. Different setup can be
made as per requirement. There are up to 10 different fields and up to 10 different setups can be saved.
Press in the general location of the clip to change any of these fields.

5.3: Automatic date system
5.3.1: Date offset
Date offset is available without unlocking the advanced parameters. To make sure to understand this
feature, read also dynamic variable and Time configuration.
The value of Date offset is in days. Press the arrows to select the desired offset. Press directly on the
black field to open a pop-up keyboard.
Note: Date offset works only with the dynamic variables.
5.3.2: Dynamic variables
Dynamic variables are functions that use the "actual time" and modify a desired field in real time. It is
very versatile.
For example: User want to print on the clip the exact hour and minute of the day the product has been
packaged. Then, he could add a specific date offset of five days which correspond to shelf life of the
product.
Note: Let’s assume the positioning is already good. To know to position and adding new fields, see the
"advanced printing configuration".
1. Press in the general location of the clip.

2. Edit the two (2) field. By adding in front a "%" and 2-4 specific caracters, then the function will
happen. In the example, hour and minute was required:
a. In the field 1: %HH (stand for hours);
b. In the field 2: %MI (Stand for minutes).
Note: User would achieve the same result by using only one WORD (field). For example: %HH:%MI in
WORD 1. Each field accept 20 characters. Moreover, there is a limit of 10 words.
3. After the specific caracters, every other caracters will show up as well, so it is possible to do
something like follow:

5.4: Changing ink cartridge
The ink level is not the absolute truth because the machine does not register a quantity of ink in the
cartridge. The level is base on when the user is changing the cartridge for a brand new one, he needs to
press on the level to reset the counting. Always check periodically the quality of print on the clip itself.
Follow these steps to change the cartridge:
1. Unclip the empty cartridge.
2. Unpackage the new one. Do not put fingers on the sensitive part as per the manufacturer
recommendations.
3. Insert the cartridge by inserting against the side.

4. Push slightly to engage the connections.
5. Clip it.
6. Press on the ink level to reset the bar. The machine will calculate how many milliliters the print
head is spraying.
