Troubles
The cutter does not work
• Is a cutter unit fi tted and properly connected to the DIN-con-
nector inside the printer’s front hatch and is the cable visibly
undamaged?
• Check the safety microswitch that prevents the cutter from
operating when opened.
• Make sure that a CUT command is transmitted in the current
program or that the cutter is enabled by means of a CUT ON
statement.
• Is the printhead lifted? If so, lower the printhead.
• Is the cabling from the printer's front to P-6 and P-606 on the
CPU board correctly connected and undamaged?
• Verify that no paper shavings, residue from label adhesive,
or foreign objects obstruct the cutting operation. Clean as
described in Chapter 12.3. If the cutter is stopped from com-
pleting a cutting operation, the motor may be damaged by over-
load.
• Measure the voltage P24 between pin 1 (+24V) and pin 3
(ground) of connector P-6 on the CPU board, when a CUT
command is being issued. Pin 2 should get a supply voltage of
almost 24V. Pin 5 is connected to an internal, home position-
sensing micro-switch of the cutter. The microswitch must be
opened, disconnecting ground from pin 5. At the very end of
a cutting cycle, pin 5 is again connected to ground, when the
microswitch closes.
• If no cause of malfunction could be found, the cutter is probably
defective.
The built-in LTS does not work correctly?
• Verify that that cable from the cutter connector on the printer's
front is properly connected to P-606 on the CPU board.
• Verify that there is no jumper fi tted on P-607 on the CPU
board.
• Adjust the sensitivity according to the same principles as the
front-mounted LTS, see Chapter 12.4.
The cutter does not cut at the right place
• Verify that the start and stop adjust values are correctly set.
• Verify that the printer is set for the right media type.
• Verify that the LSS works correctly correctly, see Chapter
26.2.
• Verify that the LTS is managed by the appropriate Fingerprint
instructions.
