6.4 Printer
A permanent record of test results can be obtained by using the built-in
printer or transmitting through the RS232 output to an external printer or
computer. Figure 20 shows a sample printout from the built-in printer.
6.4.1 Built-In Printer
The 2100AN Turbidimeter has a built-in 28 column thermal printer. The printer is
active for output when the printer selection setup (number
02
) is set to
INT
or
BOTH
(see Section 6.4.2.2).
Observe the following procedures with the built-in thermal printer for best results:
•
Always use Hach thermal paper (Cat. No. 47090). Use of other thermal paper
may result in marginal print quality and reduced print-head life.
•
Leave the roll of thermal paper in the sealed plastic wrapper until the paper
is used.
•
Do not rub the thermal paper with a hard object.
•
Do not use chemical paste on thermal paper.
Note: A red line on the edge of the thermal paper indicates when the paper supply is low.
6.4.1.1 Loading Paper into the Built-In Printer
Note: Always use Hach thermal
paper (Cat. No. 47090-00). Use of
other thermal paper may result in
marginal print quality and reduced
print-head life.
The following steps describe installation of a new roll of thermal printer paper into
the 2100AN Turbidimeter. Removing the printer access door may simplify paper
replacement. The printer door hinge pin (located on the left side) is slotted for
easy removal when in the full open position. Open the door carefully and lift the
left pin from the slot. Carefully remove the printer door. Reverse the procedure
starting with the hinge pin located on the right side to reassemble.
1. Cut the end of the paper into an arrow shape using scissors.
2. Open the printer access door.
3. Insert the point of the printer paper into the paper entrance slot on the back of
the printer.
4. Push the printer paper through the entrance slot until the point of the paper
appears at the exit slot.
5. Pull the point of the paper out of the exit slot until the full width of the paper
is visible and clear of the opening.
6. Insert the point of the printer paper through the slot in the printer access door
while closing the printer door.
7. Pull the paper to advance through the printer, or press
LINE FEED
to advance
the paper one line at a time.
