Removing Jammed Paper
Note: If the cutter remains blocked due to a paper jam, unplug the printer and use the manual lever to move
the cutter blade prior to perform the steps below.
If a paper jam occurs, follow the steps below:
1. Cut the paper at the paper entrance.
Presenter Lock

2. Push down the Presenter lock (Figure 12)
and gently move the Presenter as indicated
(Figure 13).

3. Unlock the head up switch raising the print head
(Figure 14).
4. Gently pull the paper out of the mechanism.

5. Lock the head up switch and bring the Presenter back to the inicial position. Lock the Presenter.
Key Panel
The key panel gives visual printer status and manual control to the operator.
These functions are accomplished using one switch and LEDs, described below:
• POWER LED: This green LED will be on whenever power is applied to the printer and the power switch is on.
• PAPER LED: This red LED will be on when the printer is without paper. If the print head is up, this red LED
will blink.
• ERROR LED: This red LED will blink in error conditions. See ERROR TABLE on next page.
• PAPER FEED BUTTON: Use to feed paper line by line with fast button touches or feed paper continuously, by
pressing and holding down the button.

Presenter can not eject the paper
Presenter Operation
The presenter mechanism is responsible for the ejection of the receipts printed by the kiosk printer. It is designed
so that paper jam probability is minimized. However, due to paper feed conditions (wrong paper feeding, paper
wrinkles etc.) paper jam may occur, especially when replacing paper. We may, then, consider the following:
• When a paper jam occurs in the presenter entrance, the paper will not reach the presenter sensor (located in
the presenter cover) – in this case, the kiosk printer goes into error condition, thus requiring manual intervention.
After removing the jammed paper (see “Removing Jammed Paper” on page 13), the printer must be turned off
and on again, in order to the printer to come back on line.
• When the paper jam occurs in the presenter paper exit, the kiosk printer will try to force the paper out for 8
seconds. If that does not happen, the printer will wait for 10 seconds, after which it will try a new paper
presenting sequence. If the second try is not effective, the printer will go permanently in error condition, thus
requiring a manual intervention to remove the paper. Note that this paper jam may occur while replacing paper
or if there is vandalizing of the paper exit. In addition, and in order to prevent that, the presenter has a clutch
device that prevents paper jamming if paper exit is blocked.
Retractable Function
It is possible to set the retractable function by command. If this feature is enabled, after a full cut command the
presenter will push the paper and return it to its sensor. By default, if the paper remains below the sensor during
10 seconds, the presenter will pull the paper automatically. The retractable delay can also be programmed by
command. The printer is prepared mechanically to pull the paper avoiding receipt jam.
Reliability of presenter operation without the recommended paper is not guaranteed.

KC-1800 · Revision 1.1
Operation Modes
The printer can be operated in the following modes:
Normal (Remote mode)
In this state, the printer is being controlled by the host through the serial, parallel or USB interfaces.
Dump mode
In this mode advanced users and programmers can identify communication problems between the host and the
printer or check if a certain programmed data is correctly being sent to the printer, thus being a debugging tool. To
start the hexadecimal dumping, turn on the printer while pressing the paper feed switch. A message will be
printed on the paper asking you to press once more the paper feed switch if Dump mode is desired, as shown:
- Press PAPER switch once for DUMP MODE
Self-testing
To run a self-test, turn the printer off. Press and hold the Paper Feed switch and turn it on. When the printer starts
printing, the paper feed button can be released. A message will be printed asking you to wait the self-test. In the selftest you will find the printer firmware version, among other information.

Communication InterfacesCommunication Interfaces
Communication Interfaces
Communication InterfacesCommunication Interfaces
Communication between a host and the printer can be performed in three communication protocols: USB, Parallel
or Serial RS-232, according to the printer model.
Communication cables are not supplied with the printer
Serial Interface
The RS232 serial interface uses a female DB-25 connector. The serial port can operate using the DTR/DSR mode,
with 7 or 8 data bits, with or without parity, even or odd parity, one start bit and one or more stop bits. In the
RS232 standard, the logic low level corresponds to a +12V voltage level and a logic high level corresponds to -12V.
DTR / DSR mode
In this mode, the printer’s DTR line controls the flow of data sent from the host’s TX line and received by the
printer’s RX pin. In this case, when the printer’s DTR signal is low (+12V) the printer requests the host to send
data. When the DTR signal is high (-12V) the printer tells the host to stop sending data.

the Bulk mode with a “B” receptacle as show below. The USB cable must have in one side an “A” plug to connect
in the host, and in the other side an “B” plug to connect in the printer. The printer is self-powered and does not draw
power from the standard type B USB interface cable.

The following table described some of the problems that might occur while using the printer. For ever y problem
there is a possible cause described here and a suggested procedure to solve the problem.
Problem
The printer does not turn on.
The printer does not respond
to the commands sent.
Parallel communication is
faulty.
Serial communication is faulty.
Possible Cause
There is no power in the electric
outlet.
A problem with the power cord – it
may be broken or not well
connected to the printer and / or
outlet.
The parallel / serial / USB cable has
one or more lines with faulty
connections / broken wires.
Wrong programming sequences.
The parallel cable has one or more
lines with faulty connections /
broken wires.
The pin layout does not follow the
Centronics standard.
The serial cable has one or more
lines with faulty connections /
broken wires.
The pin layout does not follow the
correct protocol.
The baud rate is incorrectly set.
Possible Cause
Check if there is a central switch for
the room / outlets. Connect some
other equipment to the outlet to
check its operation.
Turn off the printer, check the power
cord’s continuity and a perfect
connection between the printer and
the electric outlet.
Check for a good connection
between the printer and the host or
change the cable.
The programming sequences can be
checked in the dump mode. Put the
printer in dump mode and run your
application again. The printer will
show the hexadecimal and ASCII
codes of all bytes being received
from the host.
Check for a good connection
between the printer and the host or
change the parallel cable.
Check the correct pin layout in this
manual.
Check for a good connection
between the printer and the host or
change the serial cable.
Check if the pin layout used
complies with the protocol being
used for data transmission.
Remember that the printer uses the
DTR/DSR protocol.
If the baud rate set on the printer is
different from the baud rate of the
host, the printer will print random
characters or not print at all. Check
carefully the host’s serial baud rate
configuration as well as the printer’s
DIP switch settings.

Cleaning the Presenter:
Remove debris and paper dust from the presenter by using a vacuum cleaner, or by blowing or by using a dry soft
brush. Perform this operation when replacing paper roll.
Printer head cleaning procedure:
Adhesion of dusts of paper and foreign materials may deteriorate the print quality and the lifetime of the head and
platen. When they adhere, clean the head according to the following procedures:
1. Take measures against static electricity such as a disposable wrist strap for the work.
2. Cleaning should be done with the presenter or the cutter (depends on your configuration) lifted up and
the platen part separated from the head (use the head-up lever).
Note: do not hit the thermal head surface with anything hard!
3. Wipe off the heating element part of the head surface lightly with cotton swabs to which Ethyl-alcohol
is applied. Be sure to clean the platen roll as well.
4. After Ethyl-alcohol has completely been dried, set the platen and perform the action check (print a self
test ticket and check the printing quality).
Note: do not use anything that may destroy the heating element, such as sandpaper. Do not apply
any unnecessary force to the thermal head.
Tests revealed that this procedure becomes necessary more often as the printer head gets used.
