17.15 Cutter Troubles
Description:
The paper cutter unit does not work properly.
Possible Causes and Suggested Remedies:
• Cutter not properly connected.
- Is the cutter properly connected to the DIN-connector inside
the printer's front hatch and is the cable visibly undamaged?
- When the CUT instruction is executed for the first time after
power up, the firmware checks the cutter device. If the
instruction fails, e.g. because no cutter is fitted, the error
message 37 “Cutter device not found” is returned. This
condition will remain, even if a cutter is connected, until next
power up.
• Intermec Fingerprint instruction missing.
- 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.
• Printhead lifted.
- Is the printhead lifted? If so, lower the printhead.
• Bad connection between cutter interface and CPU board.
- Is the cable from the printer's front to P58 on the CPU board
correctly connected and undamaged?
• Cutter mechanism jammed.
- 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
completing a cutting operation, the motor may be damaged by
overload.
• Wrong voltage.
- Measuring the voltage on connector P58, pin 1 (P24) to pin 3
(GND) or pin2 (cutter output) to pin 3 (GND) when a CUT
instruction is executed should give a voltage of 24V
during 2 seconds.
- Pin 5 on connector P58 is connected to a microswitch sensing
the cutter's home position. At rotation, the switch closes pin 5
to pin 3 (GND) and at the very end of the cutting, the
microswitch opens up which indicates that the cutter is back.
At home position, the microswitch is normally open.
- If no voltages, check if the printhead is lowered completely.
- Check if the headlift sensor provides the correct signal when
the printhead is lowered (see chapter 8.8).
- Check if the printer anything at all. If so, the P24 voltage is OK
and T57–59 or the surrounding resistors may be damaged.
• Slack return spring.
- The return spring in the cutter mechanism could eventually get
slack and need to be replaced.
• No cause of malfunction could be found.
- The cutter motor is probably defective. Replace the entire
cutter or just its mechanism.
