26.9 Standard Cutter
Troubles
• 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?
• 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 cable from the printer's front to P-6 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, discon-
necting ground from pin 5. At the very end of a cutting cycle,
pin 5 is again connected to ground, when the microswitch
closes.
• The return spring in the cutter mechanism could eventually get
slack and need to be replaced.
• If no cause of malfunction could be found, the cutter is prob-
ably defective.
