I. GENERAL INFORMATION
I. a–INTRODUCTION:
A Traulsen Blast Chiller will come standard with one printer, the
record printer. All SmartChill® controls have the option to enable
or disable the use of a second printer, the label printer.
When facing the front of the unit the record printer is located in
the left printer housing and the label printer is in the right printer
housing.
Both printers, record and label, have the same part number
950-60355-00 and are interchangeable with the exception of
any RBC50 models manufactured prior to 2008, with 90 degree
printer boards in which case the part number is 950-60408-00.
I. b–OPERATION:
SmartChill® printers are thermal printers, meaning no ink is required. Upon receipt of a signal from the SmartChill® control,
the printers will print specied data. The record printer ONLY
uses 2 ¼” thermal paper and the label printer ONLY uses 2 ¼”
Traulsen thermal label stock part number 400-60004-00.
The record printer will print power on diagnostics information,
single batch data, and twelve hour data logs.

I. GENERAL INFORMATION (cont’d)
I. f–ENABLE-DISABLE LABEL PRINTER (cont’d):
To enter from the keypad, press “MORE” from the “MAIN
MENU”. Press “SETUP”, and change the “PASSWORD
(PIN)” to “85”. Press and hold the upper left, upper right
and lower right keys simultaneously. Then release all
keys. Display will read as follows:
Press “NEXT”, this will bring you to the Label Printer
option screen:
II. BASIC SERVICE PROCEDURES
& ADJUSTMENTS (cont’d)
II. c–LOADING THE PRINTER MEDIA:
• Place printer media on spindle (see gure 1; reference 7).
• Fold the end of the printer media to a centered point allows
smoother transition when feeding (see gure 1; reference 4).
• Lift the cutting wheel cartridge (see gure 1; reference 3) and
release the feed roller tension arm (see gure 1; reference 6).
• Feed the printer media over the feed roller (see gure 1; refer
ence 5) and through the cutting wheel cartridge.
NOTE: Thermal coating side must face up.
• Engage feed roller tension arm and cutting wheel cartridge.
II. d–RUNNING A TEST PRINT:
• Start at the “MAIN MENU”
• Press “MORE”
• Press “SET UP”
• Change “PASSWORD (PIN)” to “75”
• Press the top left, top right and the bottom right buttons
simultaneously and release to enter the “SERVICE MENU”
• Press “NEXT”
• Select “PRINTERS”
• Press “RECORD READY” or “LABEL READY” for a test print.
Press the up or down arrow to toggle between “LABEL
PRINTER (NO)” and “LABEL PRINTER (YES)”.
Press “NEXT” until you reach the screen with “EXIT” option. Press “EXIT” then press “YES” to save settings.
II. BASIC SERVICE PROCEDURES
& ADJUSTMENTS:
II. a–CHECK RECORD PRINTER MEDIA:
The record printer must be loaded with 2 ¼” thermal
paper. The thermal side must be facing up.
Verify paper has thermal coating by running a blunt object across the thermal coating. The friction will create
enough heat to leave markings on the thermal coated
side.
II. b–CHECK LABEL PRINTER MEDIA:
The Label printer must be loaded with 2 ¼” Traulsen
label stock, part number 400-60004-00. Labels must
be facing up.
Traulsen label stock can be identied by the ½” or by
¼” black place marker on the top right corner of each
label.

IV. ADVANCE SERVICE PROCEDURES & ADJUSTMENTS
IV. a–CUTTING WHEEL OPERATION:
The cutting wheel is located in the cutting wheel cartridge (see
gure1; reference 3; page 2). The cutting wheel moves right to
left to cut paper/labels then resets back to the right.
The cutting wheel must reset all the way back to the right for the
printer to initialize. If the cutting wheel jams the printer will not
initialize and will not print.
If debris is blocking the cutting wheel remove debris and cycle
power. The cutting wheel should reset on its own. If cutting
wheel does not reset, manually reset the cutting wheel by adjusting the plastic Phillips head adjustment screw located on the
left hand side of the cutting wheel cartridge. If the wheel will not
move or is very resistive in movement it is likely it will not reset
properly and the printer must be replaced.
IV. b–CHECK PRINTER POWER-BASIC:
1) The quickest way to verify the printer is receiving power is to
release then re-engage the feed roller tension arm (see gure
1; reference 6; page 2). Any time the feed roller tension arm is
re-engaged the printer should index the printer media approxi-
mately 1/8”. The printer media will also index on system power
up.
2) If the printer media does index when the feed roller tension
arm is engaged and printer still does not print then reference
Section II. a, b, c, & d to check printer media or Section IV. d to
check data cables and SmartChill® control.
IV. c–CHECK PRINTER POWER-ADVANCED (cont’d):
4) If 2 pin connector is secure and has proper voltage
and still does not print, replace printer.
5) If 2 pin connector does not read 8.5VDC check DC
power supply for proper voltage. (Voltages are labeled
on relay board and DC power supply terminals). For
more information on troubleshooting DC power supply
contact Traulsen Service Department at 800-825-8220.
IV. d–CHECK PRINTER DATA HARNESS:
The white harness is the printer data harness. If the
printer indexes when following instructions in Section IV.
b but does not print, check the white data harness (see
gure1; reference 2; page 2) for damage or weak connection.
IV. e–INTERCHANGE INSTRUCTIONS:
Both printers, label and record, are exactly the same
printer and interchangeable. When plugged into PTR
1 ports (see gure 2; reference 1; page 5) on the back
of the SmartChill® board the printer will act as a record
printer. When plugged into PTR 2 ports (see gure 2;
reference 2; page 5) on the back of the SmartChill® board
the printer will act as a label printer.
NOTE: Always inspect all boards and cables for signs of
water damage or corrosion. Corrosion will impede printer
and or control board operation.
3) If the printer media does not index when the feed roller tension arm is engaged reference Section IV. c to further check
printer power.
NOTE: The printer media will not index if the cutting wheel is
jammed.
IV. c–CHECK PRINTER POWER-ADVANCED:
1) The red harness is the power harness for the printer. Ensure
this harness is plugged in securely and shows no signs of dam-
age to both the printer (see gure 1; reference 1; page 2) and
the SmartChill® board (see gure 2; page 5).
2) If the red power cable seems to have a weak connection
tighten the connection and refer back to Section IV. b to check
printer operation.
3) If the red power cable seems to be secure and shows no
signs of damage, check the 2 pin connector, grey and black
wires, on the back of the SmartChill® board (see gure 2; refer-
ence 3; page 5) for 8.5VDC and secure connection.

VII. TROUBLESHOOTING
Certain procedures in this section may require electrical and refrigeration system test or measure ments while power is applied to the cabinet. Exercise extreme caution at all times. If test points
are not easily accessible, disconnect power, attach test equipment and reapply power to test.
Not Printing1. Check printer media to insure it is the proper type and loaded properly see Sec. II. a, b.
2. Check printer power see Sec. III. b, c, d.
3. Check for water damage or corrosion see Section III. e.
Loading Media1. Always fold the tip of the media to a point Section III c.
Error Code1. Check Printer Media.
2. Generic error message indicating a printer has failed to print (printer not specied).
Corrosion1. Routinely inspect printer boards, cutting wheel cartridges, cables & board for signs of
corrosion.
2 Pin Connector1. Often after resent service the 2 pin connector (grey and black wires) on the back of the
SmartChill
®
control can become loose or disconnected causing a printer failure.
Verify Printer Power 1. The quickest way to verify a printer has power is to release then re-engage the
tension arm. The printer should index the media about 1/8”.
Printer Fails To Initialize1. If a printer continues to feed paper with only a few random characters printed every so
often, the printer has failed to initialize. If this happens simply power cycle the control.
Printer Replacement1. Both printers, record and label, have the same part number 950-60355-00 and are inter
changeable with the exception of any RBC50 models manufactured prior to 2008, with
90
degree printer boards in which case the part number is 950-60408-00.
